采用同池比较法 ,研究了一龄和二龄阶段“全红”、“大花”、“麻花”、“粉玉”及“粉花”五种不同体色瓯江彩鲤生长率和存活率的差异 ,结果表明 :( 1 )在一、二龄阶段 ,“麻花”存活率均最高 ,分别是 98.8%和96.3% ,但各体色彩鲤间差异不显著 ( P>0 .0 5) ;( 2 )不同体色彩鲤的生长率在不同阶段表现不同。一龄阶段 ,不同体色彩鲤的绝对增重率、瞬时增重率均依次为“大花”>“麻花”>“粉花”>“全红”>“粉玉”,差异极显著 ( P<0 .0 1 ) ;二龄阶段 ,不同体色彩鲤的绝对增重率、瞬时增重率均有显著差异 ( P<0 .0 5) ,但次序和I龄阶段不完全相同 ;( 3)一龄阶段 ,“大花”和“麻花”始终保持较快的增长 ;二龄阶段 ,则是“粉玉”和“大花”始终保持较快的增长 The same pool comparison method was used to study the growth rate and survival rate of Oujiang color common carp in five different body colors, “red”, “big flower”, “twist flower”, “pink jade” and “pink flower” The results showed that: (1) In the first and second instar stages, the highest survival rates of “twist” were 98.8% and 96.3%, respectively, but there was no significant difference between each color carp (P> 0.05) 2) Different body color carp growth rate in different stages of performance. In the first instar, the absolute weight gain rate and instantaneous weight gain rate of different body color carp were in the order of “big flower”> “twist”> “pink flower”> “all red”> “pink jade” <0. 01). In the second stage, the absolute weight gain rate and instantaneous weight gain rate of different body color carp were significantly different (P <0.05), but the order was not exactly the same as that of I stage ) In the first age stage, the “Big Flowers” and “Twigs” kept a relatively fast growth. The second growth stage was that “Pinks” and “Big Flowers” always maintained a relatively fast growth
