You read about some concerns that have been raised about farming tuna.However,researchers are finding promising solutions to these problems.
First, it’s true that tuna farms need to be stocked with wild young, but this may soon no longer be the case, thanks to a breakthrough. Scientists found that they can get captive females to lay their eggs by injecting them with certain hormones. These injected hormones get the females to lay eggs reliably, without posing health risks to the tuna or to the consumers later on. With this advancement, tuna farming can be done without further reducing wild populations.
Second, yes, tuna must eat a high-protein diet and they usually get protein from fish, but the protein that tuna need doesn’t have to come from fish. It can also be gotten from plants. Certain plants that are high in protein can be processed to make an inexpensive food for tuna. This food made from plants could supply captive tuna with all the protein and nutrients they need,and since the plant-derived food is inexpensive, the cost of tuna from tuna farms can be kept low.
Third, parasites attack many ocean fish farms, but steps can be taken to treat infestations. For example, scientists studying a parasite problem in tuna farms in southern Australia discovered how to greatly reduce blood fluke infestations there. They found that when tuna cages were moved farther off-shore into deeper waters, far fewer tuna had blood flukes in their bodies. It turns out that blood flukes need to stay close to shore to do well. That’s because certain resources that blood flukes require for their life cycle are not available farther off-shore. Because the tuna cages were moved into deeper waters where the blood flukes cannot thrive, blood fluke infestations among the caged tuna were basically stopped.
The article states that Wild tuna, a specific kind of large ocean fish, are in danger of extinction due to overfishing. Farming tuna in cages is an idea presented in the reading to compensate for this decline but provides three problems for this idea. However, the professor explains that there are promising solutions for these problems and refutes each author's reasons.
First, the reading says that there is no chance for female tuna to lay eggs in captivity. The professor opposes this point by explaining that there is a specific hormone that can be used to increase the ability of female tuna to lay more reliable eggs. Thanks for this development to solve the female problem.
Second, the article posits that farming tuna is an expensive field because it depends on other fish' costs. In contrast, the professor says that tuna feed on sea plants rather than fish. According to the professor, tuna can meet their needs in a different way from other large fishes, and this could be a significant advantage for tuna farmers to raise tuna at a lower cost.
Third, the reading says that it is likely that tuna in cages are appropriate for parasites' infection. The professor casts doubt on this point by explaining that more attention could be paid to the location of these cages. He also states that tuna are risky for parasite attack if their cages were far from shores because the location close to the shore provides more suitable environments for tuna and decreases the possibility of growing any kinds of parasites.
