Chromosomal Analysis of Selected Freshwater Ornamental Fishes

Chromosomal analysis of six freshwater ornamental fishes, Red tail shark minnow (Epalzeorhynchos bicolor), Tiger loach/Zebra loach (Botia striata), Red fin shark (Epalzeorhynchos munense), Silver shark (Balantiocheilos melanopterus), Albino rainbow shark (Epalzeorhynchos frenatus) and Rani loach (Botia lohachata) collected from natural water body or ornamental fish hatcheries located in Howrah, Hooghly and South 24 Parganas of West Bengal, India was carried out. The diploid chromosome number (2n) of Red tail shark minnow, Tiger loach/Zebra loach, Red fin shark, Silver shark, Albino rainbow shark and Rani loach were found to be 50, 50, 40, 50, 46 and 78 respectively.
