Integrated Tpo 65 (Tuna Fish Farming,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,)
Reading passage:
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.
Both the reading and the lecture discussed about the concerns related to wild tuna, a large ocean fish whose number is decreased due to overfishing. The passage explains the problems; however, the speaker provides some promising solutions for the mentioned issues by the author.
First of all, the text claims that due to the fact that female tuna can not lay eggs in captivity, farmers must capture more young tuna for feeding them and selling them after their growth. As a result, the tuna population will be decreased in response to the action. Conversely, the lecturer says that the problem is solved by the technology which injects a hormone into the tuna. The hormone gives rise to laying eggs by the tuna. Moreover, the hormone is not dangerous and both the tuna and its eggs will be healthy after injection. Therefore, the advancement solves the mentioned issue by the author because the farmers do not need to capture myriad numbers of tuna.
Secondly, the author states that the tunas need high protein foods in large quantity that is expensive and costly. So, tuna farming is not profitable. On the other hand, although the lecturer accepts that the tunas need a high protein diet, she believes that if we supply the necessary proteins by plants instead of fishes, providing tuna's food is not costly anymore. Actually, the plants which are full of protein are cheap; so, the author's concern can be solved by the idea.
Finally, the passage explains that various tunas are infected by special parasites such as blood flukes that do not let them grow and kill them. Nevertheless, the professor talks about a remedy that is at the hand for facilitating the disease. She says that many ocean animals are infected by parasites. However, we can treat the disease. For example, in southern Australia, the problem is solved by replacing the tuna cage to deeper water because the blood flukes parasite can not be alive at the deep part of the ocean. It is due to the fact that the vital food for the parasite is available in the close shore water. Therefore, by transporting tuna to offshore water, tuna will not be infected by the blood flukes because the parasite can not thrive at the deep ocean.
