摘    要:以半滑舌鳎渤海野生群体和人工养殖群体为基础群体,建立了半滑舌鳎家系18个。对不同家系鱼苗进行荧光标记后放在同池进行生长比较,结果表明不同家系鱼苗生长速度差异显著,筛选出生长快速的家系2个(家系15和16号),生长较快的家系4个(家系6号、7号、16号和30号),生长速度一般的家系12个(家系1号、3号、4号、10号、12号、14号、19号、24号、27号、28号、33号和34号)。利用鳗弧菌感染其中12个家系,结果显示,2号家系感染后的成活率为79.25%,被认作抗病力强家系;2个家系(12号和14号)感染后的成活率为50%~60%,被认作抗病力较强家系;6个家系(3号,6号,7号,10号,16号和19号)成活率为35%~50%,被认作抗病力一般的家系;3个家系(15号、27号和30号)的成活率在35%以下,被认作抗病力差的家系。结果表明通过家系选育方法可以筛选出生长速度快、抗病力强的半滑舌鳎优良家系,从而为半滑舌鳎高产、抗病优良品种培育提供新的技术手段。

关 键 词:半滑舌鳎  家系  选育  生长率  抗病力

Abstract:Half-smooth tongue sole(Cynoglossus semilaevis G?nther)is distributed along the coast to the Yellow Sea,and Bohai Sea.It is a cultured marine fish species which is highly valued because of its delicious,tender meat and nutrition.However,diseases of the farmed fish have taken place constantly and yield losses due to epidemic diseases restrict earnings and progress of fishery.To develop new strain with enhanced disease-resistance and fast growth is an important task in tongue sole aquaculture.In the present study,wild population from Bohai sea and cultured population were used as basic populations.18 families of half smooth tongue sole were established.Growth comparison indicated that significant differences were observed in growth rate among the 18 families.Among these 2 fast growth families(family 15 and 16),4 secondly fast-growth families(family 6,7,16 and 27),and 12 common growth families(family 1,3,4,10,12,14,19,24,27,28,33 and 34)were obtained.12 families were chosed for pathogenic bacteria, Vibrio anguillarum,challenge experiments which showed that one family(family 2)had strong disease resistance with the survival rate of 79%;2 families(family 12 and 14)had secondly strong disease resistance with the survival rate of 50%-60%;6 families(family 3,6,7,10,16 and 19)had common disease resistance with the survival rate of 35%-50%;and 3 families(family 15,27,and 30)had low disease resistance with the survival rate of less than 35%.
Keywords:Cynoglossus semilaevis  family  selection breeding  growth rate  disease resistance
