Halda River is the only natural site and the only carp farming in Bangladesh, where fertilized eggs are of carp anglers and egg collectors in April-June raised almost every year since time immemorial. The collected eggs are incubated in artificial mud made the scoop on the river in order to produce carp fries. Seedlings are shipped from here to various parts of the country for aquaculture.

Based on these risk factors, the river was once a haven for fish, egg release is now a very dangerous result of the drastic decline in the availability of eggs and fish fries natural species, less farmed fish have come here for the release of eggs in recent years.
