摘要
采用鱼鳍细胞空气干燥法制片,Giemsa染色,对厦门沿岸海域2种虾虎鱼的染色体核型进行了分析研究.其中,犬牙缰虾虎鱼(Amoya caninus)的染色体数目为2n=50,臂数为NF=84,有8对中部着丝点染色体(M),7对亚中部着丝点染色体(SM),2对亚端部着丝点染色体(ST)和8对端部着丝点染色体(T).髭缟虾虎鱼(Tridentiger barbatus)的染色体数目为2n=44,臂数为NF=68,有5对中部着丝点染色体(M),6对亚中部着丝点染色体(SM),1对亚端部着丝点染色体(ST)和10对端部着丝点染色体(T).未发现有异形染色体.其中犬牙缰虾虎鱼的染色体数目是文献中尚未报道的1类虾虎鱼染色体类型.
The karyotypes of two Gobioid fish species were evaluated based on metaphase of fin cells by the colchicine-hypotonic-air drying and Giemsa staining technique.The fish were collected from the Xiamen coastal waters.The Amoya caninus has 50 chromosomes and is diploid.Its karyotype comprises 8 pairs of metacentric chromosome（M）,7 pairs of submetacentric chromosome（SM）,2 pairs of acrocentric chromosom（ST） and 8 pairs of telocentric chromosome（T） with a fundamental arm number（NF） amounting to 84.The diploid number of Tridentiger barbatus is 44,the karyotype shows 5 pairs of metacentric chromosome（M）,6 pairs of submetacentric chromosome（SM）,1 pair of acrocentric chromosome（ST） and 10 pairs of telocentric chromosome（T）,with a NF of 68.No satellite chromosomes,sexual chromosomes or special chromosomes were detected in either Amoya caninus or Tridentiger barbatus.Amoya caninus with these diploid numbers has not been previously reported.
