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 a 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 the lecture are both about the concerns about tuna farming. The author of the reading feels that tuna farming has faced some obstacles. The lecturer challenges the claims made by the author. He believes that there are promising solutions to overcome these problems.
To begin with, the author argues that females in tuna farms cannot lay eggs. The article mentions that caging tuna without reproducing is going to worsen the decline of tuna populations. This specific argument is challenged by the lecturer. He claims that this problem can be solved by injecting females in the tuna farm with hormones. Additionally, he says that these hormones will allow laying eggs and increasing the number of tuna on the farm.
Secondly, the writer suggests that the tuna farm will cost a huge amount of money. In the article, it is said that tuna feed on high-protein food derived from fish, and this kind of food is expensive. The lecturer, however, refutes this by mentioning that getting protein does not have to be from fish. He elaborates on this by bringing up the point that cheap plants can provide all types of protein and can be used in the tuna farm.
Finally, the author posits that the tuna in the tuna farm can be infected with parasites that might weaken the tuna. In contrast, the lecturer notes that it has been found that the tuna caged in deep-sea will get sick, while the tuna near the shore is healthy and does not have any diseases. His position is that the cage better is placed near the shore.
