Reproductive processes are by no means fully impaired in captivity. The gradual and progressive development of the gonads remains, in general, uninhibited upto the final stage of gamete maturation, and it is only at the point of gamete release that the sequence is arrested. Both gonadal maturation and breeding behaviour have long been known in responses to environmental stimuli viz., temperature, light, rainfall etc. Our fishery scientists have made a timely breakthrough by inventing the technique of induced breeding through hormonal manipulation. Though the induced breeding technique has now been successfully used for carps many brackishwater and marine fishes have either responded to this technique with partial success or no response. This is because of the lack of understanding the mechanisms involved in the environmental complexities and their impact on neuroendocrine mechanisms in control of reproduction.
