摘要
本研究主要对标记枪注射法植入电子标记的水温条件与鱼种规格进行了分析与评估。本文通过对大、小两种规格的虹鳟,在不同水温条件下电子标记过程中生长和存活情况进行了评估,以期获得利用该方法植入电子标记的最佳时机。研究结果表明:12℃水温条件下,大规格鱼种在生长、成活率上与对照组均无显著差别;小规格鱼种在成活率上与对照组差异显著。7℃水温条件下,大规格和小规格鱼种在成活率上与对照组均差异显著。水温12℃,体重50g,体长16cm以上的虹鳟是电子标记最佳的植入时机。
In this paper,in order to looking for the optimum implanting period,the growth and survival rate of yearling rainbow trout with two kinds of sizes after implantation at different water temperature were evaluated.The results showed that there were no significant differences in the survival rate and growth of yearling tagged rainbow trout with 50g in comparison with the control group at 12℃,but yearling tagged rainbow trout with 30g was not exception in the survival rate under the same condition.Moreover,there were significant differences in the survival rate of rainbow trout with two sizes in comparison with the control at 7℃.Thus,we suggested that it is the optimum implantation while the yearling rainbow trout has 50g of body weight and more than,16cm of body length at 12℃.
