Comparison of Reproductive Performance,Growth Performance and Disease Resistance Performance among Acipenser schrencki ,Acipenser baeri and Their Hybrid Offsprings
摘要
Abstract
This study aimed to compare the reproductive performance,growth performance,muscle nutrition and disease resistance performance among four kinds of sturgeon (A.schrencki ,A.baeri,A.schrencki ♀ x A.baeri♂(simply called schhybrid),A.baeri ♀ x A.schrencki♂ (simply called baehybrid).The Results showed:the absolute fecundity of A.schrencki was 80 000-280 000 granules and that of A.baeri was 50 000-160 000 granules;the average fertility rate of the four kinds of sturgeon was from 70% to 90%,the hatching rate from 60% to 80%,while the average fertilization rate and hatching rate of A.schrencki were the highest,and those of baehybrid was higher than those of schhybrid.The average opening rate of the four sturgeons was 85%-95%,and the highest was found in baehybrid,the next was in schhybrid.There was no significantly difference among the main muscle nutrition of the four sturgeons (P > 0.05).When 2-month old,the survival rate of baehybrid was the highest;when 12-month old,the average body length and weight of the two hybrids were higher than those of A.schrencki and A.Baeri(P>0.05).The a value of the four sturgeons was approximately 3 when 2-12 month old,so they all belonged to the constant growth style.The condition factor (CF) of the four sturgeons was 0.33 to 0.44.The activities of ACP,AKP,SOD of five immune tissues in baehybrid and schhybrid were higher than those in A.schrencki and A.baeri,while the activities of NO,MDA were lower.The experiment results roughly showed that the hybrid offsprings of A.schrencki and A.baeri are good,especially baehybrid.关键词
