Aquatic Biotechnology is now at the stage where practical applications are being identified and commercialized. Governments and the public are increasingly aware of the potential of aquatic biotechnology to product healthy, quality and pollution free aquatic products for consumption and medicinal purposes. The public expects that government will ensure biotechnology activities and products are safe for humans and environment. They also see a role for their government help in capitalizing on the potential of biotechnology to increase employment, economic and environmental securities.
Aquatic Biotechnology
Aquatic Biotechnology includes several components: aquaculture biotechnology (fish health and broodstock optimization); aquatic bioprocessing (obtaining valuable compounds from marine organisms); and aquatic bioremediation (use of microorganisms to degrade toxic chemicals in the aquatic environment)
Benefits of Aquatic Biotechnology
Aquaculture sector has benefited significantly from various enabling technologies that improve fish health and broodstocks. Biotechnology is emerging as an important subset of these enabling aquaculture technologies and its application promises important economic returns as well as health and environmental benefits.
Contributions of Aquatic Biotechnology to Mankind
Aquatic Biotechnology has also been instrumental in the design of new pharmaceuticals and medicines. The chemical properties of a pacific sponge species have been used to produce over 300 chemicals, many of which are used as anti-inflammatory drugs for cancer and arthritis. Dogfish sharks, horseshoe crabs, and nudibanchs (sea slugs) are a few of the many marine species used in medical research to better understand and address neurological disorders such as Alzheimers and Parkinsons disease. The adhesive responsible for barnacle attachment has been studied for mending broken bones.
World Aquaculture Markets
World Fisheries exports in 2004 is worth over US$63 Billion annually and growing. The United Nations Food and Agricultural Organization (UNFAO) reported that by 2030, aquaculture will provide 50% of the total fish production worldwide. Worldwide, over a billion people rely on fish as their main source of animal protein and some island states depend on fish exclusively.
Currently, 70% of the total food fish supply is obtained from fishing in marine or inland waters; 30% is derived from aquaculture. The total food fish supply has been growing at a rate of 3.6% per annum since 1961, while the world's population has been expanding at 1.8% per annum. The proteins derived from fish and other marine creatures account for between 13.8% and 16.5% of the animal protein intake of the human population.
According to the UNFAO, ocean fish resources have dramatically worsened. About 47% to 50% of wild stocks are fully exploited and are therefore close to maximum limits. Another 15% to 18% are over exploited and have no further potential. The remaining 9% to 10% of wild commercial fish stocks have been completely depleted. The current Australian CSIRO report on the future, released in November 2002, paints an even gloomier picture, with some commercial species facing imminent extinction.
The average consumption per capita increased from about 9kg per annum in the early 1960's to 16 kg in 1997. This shows a doubling in consumption, outpacing the population growth.
Pharmaceutical And Biotechnology Industry
Because of our ever-increasing population that is predicted to reach eight billion by 2020, the need for food will remain a top priority, transcending all socio and geo-political boundaries. The increased demand for food will call on agriculture, specifically, to act as the biggest source of industry. And with the increased demand for foodstuff, better-quality yield and huge agricultural output will be required. (Though there has been vast improvement in the sector thanks to the improved quality of seeds, pesticides, and fertilizers.)
This is where the agriculture biotechnologist steps in. Agricultural biotechnologists are professionals who provide a set of tools, which, if incorporated suitably with other technologies, can be used for the sustainable development of agriculture and the food industry as a whole.
Scope of the Agri-Biotech Industry
With increased R&D efforts in the agri-biotech industry, the scope of agriculture-based biotech work has become tremendous. Agriculture biotechnologists' roles are multifarious. From being people with strong scientific expertise to being good administrators and good marketers with sharp business acumens and strong communication skills, the career options for an agri-biotechnologist are vast. Choosing the right avenue is the main priority.
Nature of the Job
Today, with modern technologies like micro propagation which allows for the multiplication of virus-free plants and tissue cultures, agriculturists have successfully combated natural hindrances to productivity such soil imbalances, crop diseases, and genetic breeding. Therefore, the agriculture-based biotech industry needs people who are qualified in the fields of molecular biology, plant transformation and tissue cultures, biochemistry, plant genetics, pathology, entomology, and agronomy for trait evaluation and integration.
Career Options for Agri-Biotechnologists
The field of agriculture-based biotechnology is evolving each day, offering numerous career options. Besides employing people for research and development, the industry also caters to various other agri-biotech-related fields including horticulture, floriculture, dairying, poultry farming, and fishery. Agri-based biotechnologists can also sharpen their academic skills by working with food processing or post-harvest technology, better known as genetically modified (GM) technology.
Career Challenges in the Agri-Biotech Industry
With growing consciousness of the ills of chemically treated foodstuff, changes in approaches to farming are taking place all over the globe. The stage has been set for the advent of bio-chemicals and bio-insecticides, biofertilizers, and biofuels. Agriculture-biotechnology careers are never short of challenges, both natural and man-made. For instance, in the next two-and-a-half decades alone, the world must produce the same amount of food or more than what it produced in the last 10,000 years.
For a biotechnologist, the challenge does not end with producing sufficient amounts of foodstuff. The challenge lies not only in meeting requirements within deadlines but, at the same time, causing minimal harm to the earth. Agriculture biotechnologists have to combat odds like the depletion of precious top-soil at the rate of seven percent in 10 years in order to fulfill the increasing water requirements which will have doubled by that time.
Other Career Options
Several other career openings are available for agri-business graduates. From the more general opportunities within the agricultural and land-based sectors such as equine management, animal science, and horticulture, to global buying and trading of agricultural produce, the opportunities are vast for agriculture biotechnologists.
