Marine biology deals with the study of various aquatic organisms. Aside from getting more information and unravelling different mysteries of the ocean, marine biologists also aim to learn more about processes that will ultimately provide for the growing needs of populations all over the globe. Aquaculture is one of these processes where people can expect higher availability and cheaper prices of goods and food. Here are some more information.

What is Aquaculture?

Aquaculture is described as the farming of saltwater and freshwater organisms such as molluscs, fishes, crustaceans and aquatic plants. Aquaculture is different from fishing. It is also called aquafarming, presents the cultivation of aquatic populations under controlled conditions. Mariculture defines aquaculture applied in marine environments. Certain types of aquaculture involves algaculture, shrimp farming, fish farming, oyster farming and the raising of cultured pearls. Some of the methods include aquaponics, integrating both plant and fish farming.

Effects on the Environment

Since aquaculture has spread rapidly, there are some individuals showing concern about the impact on the environment. Aquaculture can be more damaging environmentally, compared to exploiting wild fisheries. The concerns involve handling of waste, side effects of antibiotics, contesting between wild and farmed types and giving feed for carnivorous fish sought after by consumers. Sufficient research and improvements in commercial feeds triggered the reduction of the environmental effects.

The Processes

You may not consider everything you just read to be crucial information about Marine Biology. But don’t be surprised if you find yourself recalling and using this very information in the next few days.

Farming carnivorous fish such as salmon boosts the pressure on wild fish. New studies present that enough diets for salmon and other carnivorous fish can be created from protein sources aside from fish meal, thereby minimizing pressure on fishery resources.

There are recirculating aquaculture systems located inland, well-located facilities and facilities applying polyculture techniques. These help manage the bad effects of fish waste to the environment. Fish waste is made up of nutrients needed in all components of food webs in the water. It is also organic. Aquaculture has a very concentrated nature that can trigger above normal fish waste levels in the water.

Types of Aquaculture

Algaculture is a type of aquaculture that includes the farming of algae species. Microalgae makes up most of cultivated algai. Fish farming is the most common type, which involves raising commercial fish in enclosures and tanks for food. Some of the fish types kept include trout, catfish, salmon and tilapia.

Freshwater prawn farming is almost the same as marine shrimp farming. The main species involved is the giant river prawn. Mariculture is described as a special branch of aquaculture that includes the cultivation of marine organisms in the open ocean. This includes the farming of oysters, prawns and marine fish. Shrimp farming is another form of aquaculture which involves the cultivation of marine shrimp to be eaten by humans.

Some countries heavily rely on aquaculture to provide for their ever-growing population, such as China. China recently accounted for about 70% of the aquaculture production worldwide. About 90% of all United States shrimp consumption is imported or farmed. Chile is also joining the bunch by doing salmon aquaculture and exporting in different regions.

Now that wasn’t hard at all, was it? And you’ve earned a wealth of knowledge, just from taking some time to study an expert’s word on Marine Biology.

Marine biology involves the study of different life forms in the ocean, both plant and animal. Scientists and individuals continue to show interest in the ocean since there are still so many things left undiscovered. Some parts of the saltwater environment remain unknown simply because human beings cannot access these readily. You have to know more about the hierarchy of the life forms and how each interact with each other and the environment.

Microscopic Beings

Microscopic life in the ocean is very diverse and is understood in the least sense by individuals. Viruses, for example, is rarely explored and considered. Phytoplankton’s function and role is understood better because of its vital position as the most numerous primary producers in the planet. Phytoplankton is grouped into cyanobacteria or blue or green algae or bacteria, diatoms, different kinds of algae like brown algae, red algae and green algae, euglenoids, cryptomonads, chlorophytes, dinoflagellates, prasinophytes and silicoflagellates.

Zooplankton is usually larger and may not be microscopic. Several protozoa are zooplankton, including radiolarians, dinoflagellates, foraminiferans and zooflagellates. Some of the beings are also phytoplankton, with the plant and animal type usually breaking down into very tiny organisms. Other zooplanktons can include arthropods, polychaetes, cnidarians, urochordates and annelids.

The Plants

How can you put a limit on learning more? The next section may contain that one little bit of wisdom that changes everything.

There ocean has very diverse plant life. Microscopic photosynthetic algae provide a big portion of the photosynthetic output of the world compared to all the terrestrial forests. Majority of the niche occupied by sub plants on terrain are usually known as seaweeds that build kelp forests. The intertidal zone is an ideal place to find plant life in the ocean, where beach grass and mangroves may proliferate. These can function as habitat for other animals.

The Fishes

Fish has transformed several biological functions from other big organisms. Fish breathe by getting oxygen from the water through the gills. The fins function by stabilizing and propelling fish in the water. Some of the most popular fishes include clownfish, sardines, bottom fish, sharks, barracuda and ling cod. Fishes will thrive in different depths and parts of the ocean, depending on their need. Some will migrate to other regions depending on the current temperature, habitat and availability of food.

Reptiles, Birds and Mammals

There are many reptiles that live in the sea like sea snakes, saltwater crocodiles, sea turtles and marine iguanas. Majority of these reptiles have to come back to land to lay their eggs. Some of the extinct species like the ichthyosaurs transformed and no longer needs to return to land. Several seabirds are also present such as penguins, albatrosses and gulls. These spend most of their time in the ocean, while others prefer to stay inland.

There are mainly 5 kinds of marine mammals. The polar bear is considered a marine mammal since it greatly depends on the ocean. Cetaceans include toothed whales like porpoises and the sperm whale. The sea otter is part of the Family Mustelidae. Sirenians include the sea cow, manatee and dugong. Seals, walruses and sea lions are grouped as pinnipeds.

On Research

If you intend to do research as a marine biologist, you need to finish college with a Bachelor of Science degree (4 years) at the very least, preferably from a known university offering specialization in marine sciences. Having this degree will allow you to work as a lab technician or on a ship running samples. You may also be assigned as a scientist. It is recommended that you have good grades in high school too.

A bachelor’s degree is not actually enough qualification to permit you to work as a scientist wherein you do your own research. You will need to get a master’s degree at the very least, but given the current employment conditions, you will also need a PhD in Marine Biology, lasting 4 to 5 years. As soon as you finish the PhD, you will be required to spend 3 to 4 years more in positions referred to as post-doctoral fellow. You can be hired as a temporary contract position by a scientist to run a part of the research semi-independently. As soon as you complete the stage, you will be considered qualified enough to be hired by a government agency, university or private research group.

Things to Do

Hopefully the information presented so far has been applicable. You might also want to consider the following:

As a marine biologist, you need to perform an active research program which includes publishing the results in peer-reviewed journals. You are also expected to review documents from other existing researchers in your field. If you are currently employed in a university, you will be tasked to teach, as well as supervise the training of research students at the PhD and Master’s level. You will need to be an active member of the community, such as joining committees in the academic department. You may also be tasked to apply for research grants. Funds are highly needed to do research.

About the Course and Other Requirements

Marine Biology is usually a major course in many universities. You can also choose to specialize further by going for areas like benthic biology or living on the ocean bottom, ichthyology or fish studies, etc. It is important to have a very keen mind, as well as the ability to be meticulous and careful. A lot of research will need you to repeat the same work again and again. Majority of scientific research does not lead to awards. You have to be patient with the developments. You will need to have a lot of positive reinforcement to stick to the course for the long term.

Tips to Get In

Always aim for good grades to stay competitive and possibly get scholarships. Focus on your writing skills and train more in your maths and computer programs. You should always volunteer as an assistant if the opportunity comes up, since what you learned in university may not entirely be the same as the actual job you will be performing once you get out of school. You will adjust to the situation more as you get more experience.

So now you know a little bit about Marine Biology. Even if you don’t know everything, you’ve done something worthwhile: you’ve expanded your knowledge.

Salary Overview

Being a marine biologist is already a dream job for several individuals since you get the opportunity to travel all over the world, study interesting aquatic plans and animals and support different conservation efforts. You do not have to worry about travel expenses, hotel accommodations and having to purchase expensive tools and equipment, since there are already plenty of facilities and laboratories available willing to provide for your every need. You can also receive grants and other financial opportunities, provided that your type of research is interesting enough to make developments in technology and history.

Asking Questions

There can be several questions asked by the average applicant. How much can I expect to earn per week or month? Will I be paid per expedition or project or by the hour? What determines the salary difference between job positions? Will experience affect the salary? How do salaries of marine biologists compare with marine service technicians salary? How soon can I expect a raise? How big a raise can I get in the first few years?

Determining Salary

I trust that what you’ve read so far has been informative. The following section should go a long way toward clearing up any uncertainty that may remain.

There can be several factors in determining a marine biologist’s salary such as location, type of industry, benefits, type of project, degree attained and level of experience. If you check the salaries according to state, you will find that Massachusetts and Washington individuals get the highest median salary.

Depending on Location

For those interested to work in sunny locations, you will find that San Diego and Miami offer the highest salaries. A marine biologist salary range can stay the same consistently during the first few years on the job. After about 10 years in the industry, you will observe the salaries tend to shoot up significantly. The salary of marine service technicians also tend to be lower compared to marine biologists. Marine service technicians can earn more than $20 per hour after working for 20 years.

Perks and Advantages

Some marine biologists may be hired on a project basis. Individuals invited into expeditions are usually very experienced and are paid higher than the rest of the group. Some marine biologists are invited because of their specific focus and thrust in terms of studying animal and plant life and the different ecosystems.

You can also get some added advantages that may not come in the form of money, such as getting free tickets or discounts to different locations all around the globe, getting access to restricted laboratories and other institutions and getting to meet people who may offer you grants and other means of support. You can also join different seminars and forums that only selected people can attend.

There’s a lot to understand about Marine Biology. We were able to provide you with some of the facts above, but there is still plenty more to write about in subsequent articles.

Marine biology is a branch of science which can also break down into several other specializations. Before you pick the course, make sure that you have the right mindset and skills to go through everything. You may be surprised to know that some aspects of the course can actually be boring and time-consuming. Here are some more guidelines on what you can expect from the course and how well you can cope with the requirements.

The Courses

Universities usually offer anywhere from 1 to 5 marine biology courses. All courses usually have the same requirements for students to enter and are very closely integrated. All courses share several basic modules. However, there are also important differences, so it is an excellent idea to view the course descriptions and modules first before finalizing your choice. The Marine biology course will delve on the biology of the organisms residing in the sea, taking into consideration the chemical and physical processes in the oceans and habitats. Marine Biology & Coastal Ecology involves a cross-system approach, wherein interactions and marine ecosystems take center stage.

Other Focuses

The Marine Biology & Oceanography course focuses more on integrating biological knowledge, with some inclusions on ocean processes. You will most likely cover topics like ocean biogeochemistry and physical processes together with the ecology and biology of marine life. One of the basic ways wherein the various ethos of the courses is developed is during the second year field course and methods modules. Join a number of course preview sessions to grab the chance to talk to students and staff regarding the various courses.

Once you begin to move beyond basic background information, you begin to realize that there’s more to Marine Biology than you may have first thought.

On Certain Changes

Once you find out more about the Marine Biology course, you may want to change your application. It is usually not a problem to transfer between 3 marine courses at Plymouth. In most cases, applicants will change their mind after joining the course preview day. Just inform the school during preview day or by writing a letter or email then amend the UCAS entry. Schools usually have a set number of places on each course to help plan for field courses and practical work. Even though the first year of every course is the same and theoretically possible to change, there might only be a very limited number of places.

The Fieldwork

The fieldwork can vary between courses. Marine Biology, Marine Biology & Coastal Ecology and Marine Biology & Oceanography typically have the same field course during the first year. The second year field course has a new emphasis. One course is located in a different place, focusing more on the experimental approach to study habitats in shallow water.

Another is found in a different location and focuses on the different kinds of flora and fauna in the region. The Marine Biology & Oceanography is done in a new location, involving boat work on a research vessel. Follow up analysis in the lab may be done. You may be provided with some pamphlets and manuals to exactly determine what you should expect during fieldwork.

Take time to consider the points presented above. What you learn may help you overcome your hesitation to take action.

The Research Coordinator

The managerial positions can land you a salary of about $75,000 to $100,000 each year, higher positions in institutional management can even reach up to $150,000 each year. As a research coordinator, you will need to create a sound expedition plan. You will also go on ships and submersibles. The work includes gathering of data and samples. The job can mean collecting invertebrates then getting extracts back at the laboratory. The extract will be checked and observed as well. Different chemicals found in the extract will be tested on different human diseases to know if there are any changes that can potentially treat.

The job requires a doctorate degree because of the high level of administrative and managerial work. You do not need to have the doctorate degree if you want to do lab work. You can also land a teaching job instead. Some courses will help you prepare better for the profession such as chemistry, molecular biology and biochemistry.

Being an Oceanographer

How can you put a limit on learning more? The next section may contain that one little bit of wisdom that changes everything.

An oceanographer earns anywhere between $100,000 and $150,000 each year. Being a full professor can help you land teaching jobs and get a bigger salary. You will typically work about 60 hours each week. The job description entails creating new graduate programs in oceanography. You have to work with groups of graduate students and continue research in different oceans and seas to boost the telepresence program. You will be tasked to watch, study and gather data from creatures, habitats, sea vents and ecosystems.

Studying Mammals

Marine biologists will have to study different organisms, depending on their location and personal preference. If you become a marine mammal biologist, you have to earn a bachelor’s degree at the very least. However, most people in the position have a master’s or doctorate degree. Salary ranges anywhere between $40,000 and $80,000. The hours per week will depend on the project and deadlines. On the average, you have to work about 8 to 10 hours per day. Some of the work entails studying the ecology of marine mammals. You have to observe the behavior and interactions of seals, whales, sea otters and dolphins.

Study the Habitat

You have to study their environment as well at different phases of their lives. You will spend several months per year writing proposals and papers. You also have to learn how to apply for grants to fund your many researches. You will spend some time on a boat or submersible too, catching, tagging, viewing and counting marine mammals. You may discover some of the rarest species and inform others how to better protect them.

As a marine biologist, you will be expected to conduct different experiments as well as research on different animals and organisms. There can be several fields that you can readily be involved in. You can study organisms that have been existing for millions of years. You can also choose to study mammals and their behavior and habitats. You can choose to directly be a marine biologist, a teacher of it or a professor in a related field.

Becoming an Oceanographer

There are three main disciplines of oceanography namely physical oceanography, marine geology and geophysics and marine chemistry and geochemistry. All these three are related. Oceanographers using these disciplines usually work together to uncover the different mysteries of ocean science. Preference is provided to projects that mix the disciplines of oceanography and use vital principles from each one to create and learn an even, process or system.

Humans need to constantly look for more ways to provide water, shelter and food, since the global population continues to grow. The oceans still have a lot to offer to support human life for several centuries. Oceanographers work to learn more about the different locations and reactions of the ocean to find more ways to meet the growing demands of the world.

Engineering Underwater

Most of this information comes straight from the Marine Biology pros. Careful reading to the end virtually guarantees that you’ll know what they know.

If you are more interested in the engineering field, you can choose to become an ocean engineer. It provides vital links to other oceanographic disciplines like chemical and physical oceanography, marine biology and marine geology and geophysics. You get to help create and invent different oceanographic tools and devices that will change the way oceans and coasts are studied. Some of the well-known instruments include sediment traps, seismometers, acoustic measuring devices, underwater vehicles and underwater video equipment.

You can gather in a few minutes data that used to take years to complete. You can conveniently work even from remote places, such as laboratories and ships. The innovations and inventions of ocean engineers have allowed oceanographers to go farther offshore and into new depths. Discoveries have been made because of oceanographic engineers like ocean volcanoes, new species of plants and animals, physical processes and hydrothermal vents.

A Writing Job

Some marine biologists are very concerned about the current condition of the ocean. You may want to work as a reporter or writer to help people become more aware about the environmental effects of various inland processes. You can start a job in environmental reporting, science writing, public relations and communications. You may also want to teach and educate people directly in colleges, museums, aquariums and universities.

More Marine Jobs

If you finish Marine Biology, you can open a lot of career opportunities. You can become one of the related professionals: science writer, marine educator, ecotourism guide, maritime or environmental lawyer, aquavet, park ranger, filmmaker or photographer, marine historian, economist, marina manager, aquaculturist, spokesperson for grants or fundraiser, environmental planner, computer specialist, hatchery specialist or ship captain or mate. You have to gauge your own hobbies, knowledge, skills and specialties to determine the best potential career.

That’s how things stand right now. Keep in mind that any subject can change over time, so be sure you keep up with the latest news.

Studying marine mammals may be one of the most interesting parts in a marine biologist’s profession. There are 3 main orders that you need to know about. Each category has its own unique mechanism, feeding pattern and characteristics. These animals tend to live in different places as well, others in groups and the rest in families or alone. Once you become familiar with their lifestyle and features, you get to appreciate the species more.

Cetacea Order

The whole lifecycle of the order Cetacea is aquatic. There are a couple of sub-orders founded ont he feeding mechanism – Odonticeti and Mysticeti. The sub-order Mysticeti includes baleen whales, blue whales, minke whales, grey whales and right whales. The whales feature mechanisms to boost the success feeding.

The sub-order Odonticeti includes animals like killer whales, dolphins, toothed whales and porpoises. River and coastal species reside in small home ranges if they are offshore. Others prefer warm equatorial waters, while the rest are located in every ocean like the bottle-nosed dolphins and killer whales. Some animals like big baleen whales move from the tropics for winter breeding to high latitudes for summer feeding. Animals propel themselves using the broad and boneless tail flukes. They also shed skin and exude oil as much as 12 times per day to reduce friction.

Pinnipedia Order

These animals adapt to the environment through a variety of processes. Heat conservation is done and get a low SA/V ratio and develop insulation through their hair and blubber. All the animals moult, after breeding in the summer while the others should stay out of water until everything is done.

Those of you not familiar with the latest on Marine Biology now have at least a basic understanding. But there’s more to come.

The respiration is done by exhaling before the deep dives. They have relatively high concentrations of haemoglobin and myoglobin. The heart of the animals drop during deep dives and the blood is limited to the heart and brain. Dives can be as deep as 1700m, lasting anywhere between 80 to 160 hours.

Sirenia Order

Sirenians are sought mainly for their hide, oil and meat. They spend their entire lives in the water and are the only aquatic animals labeled as herbivores. The flat tail propels itself via paddles. These can walk at the benthic or move backwards. Locomotion is usually slow but they can also burst at around 13 knots. Sirenians inhale before they dive, just like whales.
When they breathe, they can swap about 90% of lung volume.

Manatees can see very clearly underwater, while taste and smell are retained. These touch when they greet each other and lead to chirps, between calf and mother. Dugongs can live for as long as 70 years but fecundity is rather low. The animals reach puberty at 10 years old and produce only 1 calf every 5 years. Their population has to be protected to maintain the ability to recover from environmental stress and hunting.

Interacting with Man

All animals have interactions with man, although sirenians are the most widely known to be friendly towards humans. Fishing nets and fishing lines tend to be a problem for most of these animals.

There’s no doubt that the topic of Marine Biology can be fascinating. If you still have unanswered questions about Marine Biology, you may find what you’re looking for in the next article.
