Abstract
Background
External factors affecting the embryonic development of fishes have importance in aquaculture and conservational studies. The temperature directly affects the development rate and hatching success of fish eggs. An optimum level of temperature is required for each species for the highest hatching rate and proper development. The Nilgiri melon barb Haludaria fasciata is an indigenous ornamental fish of India and this study aims to find the effect of temperature on its embryonic development and find the optimum temperature for hatcheries.
Methods
The H. fasciata were bred in a controlled condition and fertilized eggs were selected for the study. The embryonic development stages were observed under a digital microscope. The eggs were incubated at different temperatures ranging from 10 to 35 C to find their effect on embryonic development on achieving each stage and hatching success.
