本文研究了眼斑拟石首鱼生长的特性以及外界因素对其生长的影响。未成熟鱼体重与体长关系为W=0.0123SL~(3.0511)(r=0.9919,3.5≤SL≤42cm),成熟鱼其关系为W=0.0042SL~(3.2422)(r=0.9098,70≤SL≤93cm);此鱼幼鱼全长与体长呈直线关系TL=1.1506SL+0.2866(r=0.9852,3.0≤SL≤7.5cm)。在适宜的温度条件下(尤其在23～28℃)鱼的生长快速,平均最大生长率达4.88g/d。在海水养殖中引起鱼死亡的临界DO值为2.0mg/dm~3左右。我国北方养殖一年鱼的体重可达500g,南方可达1000g左右。其生长率第一年大于1.16g/d,第二年大于2.14g/d,第三年大于3.97g/d,该种鱼在我国是一种有发展前途的新品种。
In this paper, the characteristics of the growth of coral fish and the influence of external factors on its growth were studied. The relationship between body weight and body length of unripe fish was W = 0.0123SL ~ (3.0511) (r = 0.9919,3.5≤SL≤42cm), the relationship of mature fish was W = 0.0042SL ~ (3.2422) (r = 0.9098,70≤SL ≤93cm). The juvenile fish had a linear relationship with body length TL = 1.1506SL + 0.2866 (r = 0.9852,3.0≤SL≤7.5cm). Fish grew rapidly under suitable temperature conditions (especially at 23-28 ° C) with an average maximum growth rate of 4.88 g / d. The critical DO value for fish death in mariculture is about 2.0 mg / dm ~ 3. China’s northern farming year fish weight up to 500g, the south up to about 1000g. Its growth rate is more than 1.16g / d in the first year, 2.14g / d in the second year and 3.97g / d in the third year. It is a promising new species in our country.
