黄海区太平洋鲱鱼(Clupea pallasi)目前为黄海重要经济鱼类之一,但世代波动大影响产量。在研究发育与人工增殖的实验中,静水孵化率低,特别在静水发育中的胚胎,位于卵块中间或底层的卵,自尾芽期后即开始不同程度的发育缓慢或停止发育。只有卵块边缘的卵或孤立的卵,才易发育与孵化。其发育程度 The Yellow Sea Pacific herring (Clupea pallasi) is currently one of the major economic fish in the Yellow Sea, but generational fluctuations have a major impact on production. In studies of development and artificial proliferation, the hydrostatic hatching rate is low, especially in the hydrostatic embryos, eggs located in the middle or bottom of the egg mass, which develop slowly or stop developing to varying degrees after the tail bud stage. Only eggs on the edge of eggs or isolated eggs, it is easy to develop and hatch. Its degree of development
