澳洲鳗仔鳗增长率及成活率的研究

Growth and Survival Rate of Australian Glass Eel

以澳洲鳗仔鳗为研究对象，测定它们在饲养初始阶段的增长率和成活率。得出其个体平均特定增长率为１．８８％／ｄ～２．３１％／ｄ，总成活率９３．７９％。与有关欧洲鳗的报道相比，其特定增长率、成活率明显高于欧洲鳗。由此证明澳洲鳗与日本鳗、欧洲鳗一样，能适应人工饲养环境和接受配合饲料。本文亦对部分澳洲鳗仔鳗因拒食导致死亡的现象作了描述和分析。

This paper studies the main rearing features of Australian glass eel ( Auguilla australis ) during the initial period after stocking. It is showed that the mean specific growth rates of the glass eels is 1.88%/d～2.31%/d and the total survival rate is 93.79%. The specific growth rate and the survival rate of Australian glass eels are much higher if compared with those of European glass eel , which proves that Australian glass eel is able to adapt to the pond condition and accept formula feed as Japanese or European glass eels . Description and analysis on the death of some Australian glass eel caused by non acceptance of feed and subsequent starvation were also made in the article.
