Wild tuna, a species of large ocean fish, have decreased in number because of over fishing 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.

野生金枪鱼是一种大型海洋鱼类，由于过度捕捞，其数量已经减少。最近，人们尝试养殖金枪鱼，把它们放在海洋的笼子里喂养，直到它们足够大到可以出售。然而，金枪鱼养殖面临着一些问题和批评。

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.

首先，雌性金枪鱼不会在人工饲养中产卵，因此金枪鱼养殖者必须捕获大量的野生金枪鱼幼崽来充实他们的农场，这将进一步减少野生金枪鱼的数量。这些小金枪鱼被关在笼子里喂养，直到它们长大可以出售。由于在金枪鱼养殖场捕获的雌性金枪鱼不能产卵来替代已出售的那些，金枪鱼养殖户继续捕捞野生金枪鱼幼崽来维持他们的农场运转，从而加剧了野生金枪鱼数量的下降。

Now listen to part of a lecture on the topic you just read about.

Professor:

You read about some concerns that have been raised about farming tuna.However,researchers are finding promising solutions to these problems.

你读到一些关于金枪鱼养殖的担忧。然而，研究人员正在为这些问题寻找有希望的解决方案。

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.

首先，金枪鱼养殖场的确需要饲养野生和幼金枪鱼，但由于一项突破性进展，这种情况可能很快就会改变。科学家们发现，他们可以通过注射特定的激素，让被捕获的雌鱼产卵。这些注射的激素可以让雌鱼可靠地产卵，而不会对金枪鱼或消费者的健康构成威胁。有了这一进步，金枪鱼养殖可以在没有进一步减少野生种群的情况下进行。

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. 。。。。此处省略300字听力原文！
