Abstract:对全长5.0~115.0mm不同发育时期鳜鱼视网膜结构及3种视细胞的密度进行了观测。结果表明:刚孵出的鳜苗视网膜感受细胞为高密度的单锥细胞,且不具视网膜运动反应。视杆细胞和双锥细胞出现较晚。随其生长发育,视锥和神经节细胞密度降低,视杆细胞密度增加。外核层细胞核与神经节细胞的比值增大,同时视网膜各层次的发育渐趋完善。全长30.0~43,0mm是视网膜结构及视觉特性发生明显变化的过渡时期。后期网膜上不同区域视锥的类型、形态和数量呈现异质分布,双锥约占视锥数量的90%。鳜鱼视觉结构的变化与其从浮游到底栖的生态迁移及捕食方式的变化相适应。

Abstract:测定了不同规格红螯螯虾在17℃和26℃条件下的耗氧率以及17℃、20℃、22℃、24℃、26℃的窒息点。结果表明:在相同温度条件下,单位体重的耗氧率和窒息点随体重增加而下降;在大小相近的个体中,单位体重的耗氧率和窒息点随温度的升高而增加。17℃时,体重0.11~2.34g的个体,耗氧率0.090~0.198mg/(g·h);26℃时,体重0.030~48.900g的个体,耗氧率0.081~0.883mg/(g·h);体重0.031~2.3408的红螯螯虾窒息点的范围在0.152~0.663mg/L之间。同时,红螯螯虾夜间的耗氧率高于白天。
