摘要:
通过一周年的采样,运用鱼类的相关生长方程研究了在网箱条件下黄鳝的生长变化。结果表明:黄色大斑黄鳝体长(L)与体重(W)相关式为: W=0.001899L3.1014(r2=0.986)。体长和体重以第2月龄增加最快。体长和体重生长方程为:Lt=28.85[1-e-0.2165(t+0.1178)] ;Wt=31.02[1-e-0.2165(t+0.1178)]3.1014 。在网箱养殖条件下生长1周年正是网箱养殖商品鳝所需要的最好苗种规格,体长达到23.35~32.98 cm,体重达到35.52~41.24 g。本文为黄鳝人工苗种养殖方式和选留人工繁殖后备亲本提供科学参考依据。

Abstract: Through one-year sampling, growth change of Monopterus albus cultured in cage was studied using related growth equation for fish. Results showed that: the related equation of body length (L) and weight (W) of yellow and big spot rice field eel was W=0.001899L3.1014(r2=0.986) . Body length and weight increased fastest in the second month. The growth equation of body length and weight was as follows: Lt=28.85[1-e-0.2165(t+0.1178) , Wt=31.02[1-e-0.2165(t+0.1178)]3.1014 . By means of one-year cultivation in cage, the fry size met the requirement of commercial rice field eel best; its body length and weight were respectively 23.35 - 32.98 cm and 35.52 - 41.24 g. This provides scientific reference basis for artificial fry breeding of Monopterus albus, and selecting and remaining reserved samples of artificial breeding.
