Wild tuna, a species of large ocean fish, have decreased in number because of overfishing Recently, attempts have been made to farm tuna by feeding the fish in ocean cages until they become large enough for sale. However, tuna farming has faced several problems and criticisms.
First, female tuna do not lay eggs in captivity, so tuna farmers must capture large quantities of young wild tuna to stock their farms, further reducing wild tuna populations. These young tuna are caged and fed until they are large enough to be sold. Since the captured females in tuna farms cannot lay eggs to replace the tuna that are sold, tuna farmers continue to catch young wild tuna to keep their farms going and so worsen the decline in wild tuna populations.
Second, tuna raised on farms are very expensive because they depend on costly, high-protein food derived from other fish. Tuna feed almost exclusively on small fish, which supply them with the proteins and nutrients they require. A single tuna can grow more than four meters long, weigh close to 700 kilograms, and eat 70 kilograms of food a day! It is unlikely that tuna farms can remain profitable while supplying so much expensive food for the tuna.
Third tuna confined to ocean cages are likely to become infested with parasites, organisms that feed on and weaken the animal they attach to. Tuna farmers off the coast of southern Australia have had problems with infestations of blood flukes, a type of parasite that lives within the blood vessels and heart of infected fish. Parasite infestations weaken tuna, slow their growth, and can even cause death, usually by making them susceptible to other diseases. Tuna farms in southern Australia have had 10 percent of their tuna die before they could be sold.
The reading and lecture are both about the difficulty regarding the tuna fish farming. The author of the reading feels that there comprises a lot of problems during the farming of tuna. The lecturer challenges the claim made by the author. He is of the opinion that the researcher has developed a promising solution in regards to this complexity.
To begin with, the reading says that female tuna does not lay eggs in the controlled condition. As a result, farmers were forced to catch a large amount of wild tuna. The speaker refutes on it by saying that the keeping of large stock would not be a problem any longer. He also points out that scientists have developed a hormone, which on injecting to the fish in captivity would cause to lay eggs--and it had no side effects on the health of the fish as well as consumers.
Furthermore, the article claims that tuna fish farming is costly--it requires a large amount of animal product diet--increases the cost of production. However, the lecturer, on the other hand, offers a counterargument on it. He discusses that farmers can use an alternative solution to this. He elaborates that instead of animal protein, they can use the processed form of plant protein. Consequently, the price would decrease.
Finally, the writer posits that tuna fish was highly contagious to parasites; blood flukes attached to it, and impedes overall growth. Additionally, it contends that only 90% would survive during the time of selling. On the contrary, the professor opposes it by asserting that some steps can be taken, as a result, the populations of blood fluke would decrease. According to him," In South-Eastern Australia, when tuna fish is raised in off-shore, its number has been decreased". It is because the blood fluke cannot complete its life-cycle far from the shore, and cannot thrive.
