柴窝堡湖高白鲑生长与移殖效应分析

Growth and fisheries evaluation of introduced Coregonus peled in Chai Wo-pu Lake

2004年6月-2007年5月，采集柴窝堡湖高白鲑标本79尾，对其年龄与生长状况及高白鲑在柴窝堡湖移殖效应进行了分析。研究表明：柴窝堡湖高白鲑1龄平均逆算体长L1=11.7cm、2龄平均逆算体长L2=26.1cm；体长与体重的回归方程为W=0．013474L^309069；高白鲑在柴窝堡湖生长正常，能够形成捕捞群体，但由于柴窝堡湖现有的渔业捕捞方式，影响了高白鲑在柴窝堡湖渔业移殖效应。

The Age and growth of 79 individuals of Coregonus peled in Chai Wo- pu Lake was investigated from June 2004 to May 2007. The results revealed that the back- calculated body length of fish aged 1 and 2 is L1 =11.7cm and L2=26.1cm respectively.By beans of biostatistics analysis,The regress fomulation between body length, L（cm）, and body weight, W（g）, may be expressed as W=0.013474L^309069 , that means Coregonus peled grew normally in Chai Wo- pu Lake. The investigation demonstrated that Coregonus peled can develop to fishery population size in Chai Wo- pu Lake, however, the fishery pattern in Chai Wo- pu Lake hold back the development of Coregonus peled population at present.
