1. ‘‘Present status of Fish Hatchery in Bangladesh’’
In the past decades the rivers of Bangladesh were the mentor natural source of carp seed production. Due to the
destruction of natural habitats and also increase demand the natural available of carp seed has largely declined and
the aquaculture venture and gradually replaced by the hatchery produced fry since early 80’s when artificial fish
breeding technique and low cost hatchery design have been successful adapted in Bangladesh.
In the year of 2014, the total carp fry production in Bangladesh was 3,52,010 kg of which 9,207 kg and 3,42,803
kg from 92 public hatcheries and 790 private hatcheries respectively. In the resent analysis shows that in 2018, the
total annual carp production was 6,87,427 kg by which, the annual carp hatchling production was 12,059kg from
government hatcheries and 6,66,088kg of carp hatchlings from 818 private hatcheries which is the 996.66% of the
total carp hatchling production in Bangladesh and where government hatcheries contribution was just 2.00%.
At present there are 824 private nurseries 102 government fish hatcheries and 124 government fish seed
multiplication farms in the country. A total of 6,86,754 kg spawn was produced from private and government
hatcheries in the year 2018. Collection of fish seed from natural ground has a
total of 9,274kg. The total fingerling production in 2018 was 236.2 lac.
In 2017-18 there were about 49 Penaeus monodon hatchery of and 46
Macrobracium rosenbergii hatcheries of which 27 hatcheries were government
hatcheries about 141204 lac bagda post larva (Pl) were produced in these
hatcheries. Almost all bagda hatcheries are located in cox’s Bazar region.

Such in coastal areas, hatcheries here have high mortality rates due the quality of the water being pumped from
underground reserves. Oxygen concentration in this water, which is used in brood and nursery ponds and
incubation jars, is very low, while the levels of dissolved carbon dioxide are high. This is an unfavorable
combination that leads to very low survival rates of hatchlings, even from the best quality eggs and resultant
economic losses. The project supported installation of aeration towers to provide additional oxygen to the water
Supported by worldfish–water flows through four to six layers of perforated galvanized sheets before passing to
incubation jars and nursing tanks. This simple process increases the oxygen level from 3 to 8 mg per liter. The

and cost $USD300 a piece, which is easily affordable by the hatchery owners.
