摘要
杂交鳢是以乌鳢(Channa argus)为父本,斑鳢(C.maculata)为母本杂交获得的子一代,相比亲本,具有生长速度快、抗逆性强、成活率高、易驯食膨化颗粒饲料的优势。概括了近几年来国内外乌鳢(♂)×斑鳢(♀)杂交繁育历史、杂交繁育技术,同时对乌鳢(♂)×斑鳢(♀)杂交子一代的遗传特性、胚胎发育、生长性能、抗逆性、血液指标、肌肉营养成分等研究现状进行了总结。
Hybrid snakehead is the first filial generation crossbred by Channa argus（male parent） and Channa maculate（female parent）.In comparison with parents,it grows in high speed,has a high survival rate,strong stress resistance and easily tames to feed puffed granule feedstuff.This paper summarized that the crossbreeding history and crossbreeding techniques of hybrid snakehead in China and abroad in recent years,and the genetic characteristics,embryonic development,growth performances,stress resistance,blood index,muscle nutrition of first filial generation crossbred by Channa argus and Channa maculate.This paper will supply some basis for germplasm innovation of Channa argus and scientific breeding of varieties.
