摘要
采用石蜡组织切片的方法,对大黄鱼(Pseudosciaena crocea)5个品系以及斜带髭鲷(Hapalogenys nitens)、牙鲆(Paralichthys olivaceus)、青石斑鱼(Epinephelus awoara)、尼罗罗非鱼(Tilapia nilotica)和条纹斑竹鲨(Chiloscyllium plagiosum)等鱼类肌肉纤维组织学特性的研究表明:野生大黄鱼与野生养殖品系肌肌肉纤维在组织学上没有明显差异,而雌核发育品系及其杂交后代则相对野生品系表现出显著差异,它们的肌肉纤维更细密;不同种鱼之间肌肌肉纤维在组织学表现出巨大的差异,是与各个种类的遗传特征和生存模式相适应的。
Muscles of 5 large yellow croaker （Pseudosciaena crocea） strains and 5 other species of fish in the southeast coastal waters were observed by using paraffin section. The results showed that among large yellow croaker strains, there was no significant difference in muscle fibers between wild fish and their cultured progenies, but gynogenesis strain and its hybrid progenies showed a greater density of muscle fibers than other strains. There were also evident differences between species, and the differences reflected the genetic features and living mode of the fish species.
