白鲫与4种鲤杂交及其自交F_1鱼苗的形态特征及生长
|
摘要
相同室外网箱养殖条件下,比较白鲫自交F_1及其与散鳞镜鲤、黑龙江野鲤、禾花鲤和兴国红鲤四种鲤鱼杂交F_1鱼苗的形态特征与生长的差异。结果显示:全长/体长、体长/体高、体长/头长、头长/头高等可量性状参数比值差异显著,可作为几者之间形态区别主要参数。其中白鲫(♀)×黑龙江野鲤(♂)的全长为体长的1.64倍,体长为体高的3.00倍,为头长的3.50倍,为尾柄宽的7.68倍,尾柄长为尾柄宽的1.48倍。各方面指标显著优于其他组别。从数据可以看出白鲫(♀)×黑龙江野鲤(♂)体略高,头略短,尾柄略窄长,体型较修长,表明该杂交组合鲫鱼体长体重增长率方面都显著优于其他组合,体型合适。
Comparative research on the Changfeng variety and Xiankeju carps early seedsʼ morphological characteristics and growth was done under the conditions of same indoor pond.The results showed that measurability parameters ratios including full length/body length,body length/body height,body length/head length,and head length/head height were significantly different.Meanwhile,these parameters could be used as the main parameters to differentiate two varieties.Hybrid F1 full length of white crucian carp(♀)× Heilongjiang wild carp(was 1.64 times to the body length,body length was 3.00 times to the body height,body length was 3.50 times to the head length,body length was 7.68 times to the width of the tail handle.The length of the tail handle was 1.48 times to the width of the tail handle.The indicators in all aspects of hybrid group were significantly better than those of other groups.It could be analyzed from the data that the white carp(♀)×Heilongjiang wild carp(hybrid F1 body was slightly higher,the head of it was slightly shorter,the tail stalk wass narrow and long,and the body shape was relatively slender,which all indicated that the hybrid carp had significant growth in body weight and body weight.In other combinations,the body type was suitable.In summary,the hybrid combination had better growth performance in the early stage.
