Abstract
Due to the reduced supply of commercially important temperate eels tropical species including Anguilla marmorata Quoy Gaimard 1824 are being targeted as an alternative to satisfy the high demand for eel products. However optimum ecological conditions for its aquaculture remained understudied. The present study evaluated the salinity conditions optimum for the growth of A. marmorata in the nursery culture. Growth performances of elvers were assessed after 90 days of culture at 0 10 15 20 and 25 ppt salinity. Results showed that survival and feed conversion ratio were not influenced by the culture salinity. Significant improvement in per cent weight gain specific growth rate and daily length increase were observed at 15 and 20 ppt. Polynomial quadratic regression analysis indicates that salinity of 18.14 ppt is optimum for the growth of this eel in nursery culture. These findings can serve as a basis for developing brackish water nursery culture of the tropical eel A. marmorata.
