摘 要:Breeding for adaptable deep sea aquaculture species sees progress in China,although some fish farmers struggle to cultivate the right species for the right price.The large yellow croaker,an ocean fish species indigenous to coastal China,was abundant until the late 1970s,when numbers went into sharp decline due to overfishing.Traditional fish ing grounds,such as Zhoushan,in the northwest of the East China Sea,saw significant reductions in catches.
