Review of an Ecological Science Research Article from a Primary Scientific Source :: essays research papers

Powell, K., 2005. Fish conjure uping, Eat your Veg, Nature, 426, 378-379.The article that I chose to review discussed the possibility of maintaining and sustaining aquaculture by changing the diets of the farmed fish. The idea of carnivorous fish turning into vegetarians would help for approaching sustentation of aquaculture. There were pros and cons to either side of vegetarianism and the maintaining of carnivores. There argon issues that would crave re search and analysis to which the seed points out to the reader. Aquaculture has increased by 5% over the past 10 years. The wild stock of fish that is caught to extend the fish farms has numbered 11 million tons, which is 12 % of the total fish hauled from the sea each year. Carp and tilapia are the most farmed fish in the industry that already are consisting of a vegetarian type diet. Salmon and trout are the next largest farmed fish. The difference is that the salmon and trout are carnivores. The author reports that the carni vorous fish are more expensive to cultivate and more resources are needful to maintain these types of farmed fish.Most farmed fish are fed on a diet that consists greatly of fish oil and fishmeal. Fishmeal is made from a protein full powder of ground up cheap fish as a source of nutrients and proteins. The problem with using these within the farm diet is that the train for the fish oil will overpower the supply as aquaculture expands and booms. The author states that the demand will outstrip supply of oil by 2010. (Powell). hang companies which supply the fish farms with fishmeal and fish oil as a basic to the diet of the carnivorous fish will seek different sources of protein. This protein could possibly come from larger fish such as mackerel, herring, and blue whiting. If this happens it would drift more pressure on the natural stock already creation harvested for other purposes. Some companies are traveling to the Antarctic to collect krill, which has repercussions for the empennage of the food chain in that the ocean itself is a primordial nett of life. The author boosts that the fish will be able to eat soya beans, corn, rapeseed, sunflower seeds, flaxseeds, and wheat gluten if converted to a vegetarian diet. The author also reports that round salmon farms already use these foods as staples in their fish farm diets.
