The River Halda in Bangladesh is Now Suitable for Fish Breeding
The egg collectors of Chattagram, Bangladesh are hoping to collect much more fish egg from the natural fish breeding area than the previous years. The natural fish breeding area is the Halda River of Chattagram, Bangladesh. Egg collectors are hopeful about it.
Lockdown is going on due to the COVID 19 coronavirus pandemic, so all the industries and vehicles are closed. This has decreased pollution a lot. And that’s why a favorable environment is created for fish breeding in the Halda river according to the researchers.
On the other hand, Hathazari Upazila Executive Officer has said that for the first time this year a list of 300 egg collectors was prepared for the planned egg collection.
Halda River is the only natural fish breeding area in Bangladesh. It is a breeding area for Rui, Catla, Mrigal, Kalibaus and Carp species of fish. If the environment is favorable then the fish lay eggs during April-June. Heavy rains, new moon or full moon, hill incline and thunderstorms are suitable for laying eggs.
Hathazari one hundred megawatt picking power plant and Asian Paper Mill is the main reason of pollution of Halda river. These were closed for a long time. So the amount of pollution has decreased. Also, the pollution has lessened because the factories nearby are closed due to lockdown.
Soil excavation with dredgers is also stopped. All these together have created a favorable environment for the fish breeding process. And so the researchers are hopeful that fish will lay many eggs this year.
Sixty tinny ponds and three hatcheries have been created for planned larval and fry production. And so for the first time this year a list of 300 egg collectors has been prepared to collect eggs in the right way.
Hathazari Upazila Executive Officer Ruhul Amin said cards would be issued to everyone who buys eggs. On the other hand, all kinds of assistance will be given to those who will collect eggs.
It has been reported that the egg collectors have completed all the preparations in the hope of collecting more eggs from this only natural fish breeding area in Bangladesh. Last year, 10,000 kg of fish eggs were collected from here.
