Biological control of Oryzias melastigma (Mc-Clelland) in less saline ponds of Bakkhali by Megalops cyprinoides (Broussonet).

A. V. Prabhakara Rao and P. K. Ghosh

In the rain-fed ponds of Bakkhali containing very low saline water (0.16 - 1.28 ppt), when large populations of Oryzias melastigma got established, such populations could effectively be checked through introduction of a few numbers of Megalops cyprinoides. The feeding intensity of the predators at different sizes on O. melastigma and the growth obtained thereof were discussed together with a description of the habitat.
