Induced breeding attempt of vulnerable freshwater mud eel, Monopterus cuchia (Hamilton 1822)

Abstract

A breeding attempt was conducted during 2012-13 for breed a vulnerable freshwater fish species Monopterus cuchia. Broods were reared in the pond of BFRI, FPSS, Santahar, Bogra, Bangladesh. For induced breeding purposes average 350g injected female and average 230g injected male of M. cuchia were stocked and after injection transferred into the three habitats such as Cistern, Hapa and Pond. Different doses were applied. Only Pond Habitat had shown the desired result by using Pregnyl. Pond was dried up and collects total three-thousand (3000) cuchia Larvae from six holes (Pit). Larvae were shifted into two habitats (a. Cistern and b. Tray). From four months results, it was observed that the mean final length and weight of fry under Tray habitat were 10.68±1.89 cm and 1.09±0.24g. Besides Cisterns habitat were 10.78±0.32 cm and 1.02±2.35g respectively. Percentage of survival rate was 80 and 77.
