Loss of Ocean Treasure: The Decline of Fish as a Sustainable Source of Food

INTRODUCTION President Roosevelt's words are truly sadly in a terrible dilemma. The surprises and rewards of fish as a source of sustainable food are decreasing day by day. The United Nations Food and Agriculture Organization, except "show fish as an animal in the world", is "estimated to be derived from aquatic animals 15 to 20% of animal protein" and " Protein source (FOA, 2014).

"For a variety of reasons, I think Asian salmon is a good food.I like many other fish, it can provide a lot of protein and healthy fat.Problem: Beyond the Central American Waterway It becomes annoying and pushes out other species, it feeds plankton and plankton is at the bottom of the food chain.If you like harmful chemical substances such as dioxin and polychlorinated biphenyl and heavy metals such as mercury I eat it in the food chain.

Please consider the soil food web like a sea lifeline. The big fish ate the small fish to the plankton which is the basis of the marine food chain. Microorganisms are "soil plankton" or the foundation of terrestrial food web. The study showed that this is indeed true. Microorganisms inevitably nourish humans by using the food chain as a climax and support the feeding of nourishing birds. Currently, basically every modern traditional agricultural practice is related to basic soil building activities of microorganisms (cultivation, fungicide, artificial fertilizer, single planting).

The sea and river are the main source of food for humans. It is strange that biosynthesis and the food chain before predation allow fish growth every time the fish becomes part of the meal. When considering the biological environment that people need to maintain a balanced ecosystem in a marine environment, the influence of the Predator - Predator food chain on the survival of large fish becomes important. The food web in the water environment starts with a microscopic phytoplankton which is the basis of the marine food chain. (Herring D, 2010). They are eaten by small fish, these small fish are eaten by big fish, and big fish are eaten by big fish.

According to the website of FishBase.org, 33,200 species of fish are known, many of which live in the sea. Many of these fish are good sources of protein, so many people eat them. Fishery is very important as fishery creates employment and can feed millions of people. Today, usually through sea fishing, the sea will provide about 2% of the calories required by people. Tuna, anchovy and squid are harvested near the sea surface. Pollock, flatfish and squid were caught near the seabed. In the North Pacific and the North Atlantic, more than 1 million tons of salmon are captured annually and nearly 8 out of 10 fish are eaten as human food. Other fish, fertilizer, glue, pet, other animal foods
