湖鲱(Coregonus artedii Lesueur)为鲑科、白鲑属。冷水鱼。广泛分布于北美洲高寒地区的江河湖泊中,是北美主要经济鱼类之一。该鱼食物链短(典型的浮游生物食性),生长快,肉质好,是寒冷地区大中水面增殖的理想品种。1997年3月从加拿大Sask省移植湖鲱的发眼卵,进行室内孵化、培育和大水面投放的初步试验,并对孵化的幼鱼的一些生理功能进行了认真观察,现报告如下。 Coregonus artedii Lesueur is a salmonidae and a white-tyrannosaurus. Cold water fish. Widely distributed in lakes and rivers in the alpine regions of North America, it is one of the major economic fishes in North America. The fish food chain is short (typical plankton feeding), fast growth, good flesh, is cold and ideal for large and medium surface water proliferation. In March 1997, the initial test of hatching, nurturing and surface watering of the eye of the lake was transplanted from Sask Province, Canada, and some physiological functions of the hatched juvenile fish were carefully observed. The report is as follows.
