KARAKTERISASI KROMOSOM SIDAT BICOLOR, Anguilla bicolor bicolor McClelland, 1844 DI WAY SEMANGKA, LAMPUNG

The eels of genus Anguilla are catadromous, their juvenile grow in estuaries, rivers and lakes, and their spawning areas being offshore in the ocean. The eels of Anguilla have high economic potency due to good taste and high protein content. Eel Anguilla bicolor bicolor has been cultured but the seed was depending on the glass eels availability from nature. However, genetic study for Anguilla bicolor bicolor in Indonesia was limited. The aim of this research was to characterize the chromosome of eel Anguilla bicolor bicolor, to be used as a basic information for conservation and aquaculture development. Chromosome preparation was done by blood culture splash method. The results revealed that the diploid chromosomes (2n) of Anguilla bicolor bicolor was 38, classified as 34 (17 pairs) of metacentric and 4 (2 pairs) of submetacentric chromosomes. Displaying karyotype formula of 2n = 38 = 34m + 4 sm
