Farming & Aqua Culture In Bangladesh
Bangladesh is a country with hundreds of rivers and ponds and is notable for being a fish-loving nation,
The main it will be more than 80 percent of the animal protein in the diet comes fromfish. Fish are caught both from natural resources and by farming .
Bay of Bengal
Marine shrimp farming is an aquaculture business for the cultivation of marine shrimp or prawns for human consumption.
By the end of 1987, the regulatory process for culturing shrimp was still relatively pure, and the average yield per hectare was low in Bangladesh.
Farm ponds during high-water exchange between the trapping or gathering of local estuaries and stocking ponds are directly acquired their stock in the wild postlarval and juvenile shrimp initially relied on.
In 1980, almost all of the Inland capture by shrimping is done by the intensive aquaculture. Farm ponds during high-water (tidal water
) exchange between the trapping or gathering of localestuaries
and stocking ponds are directly acquired their stock in the wild postlarval and juvenile shrimp initially relied on. Shrimp are associated with mangrove
in the wild.

Mangrove estuaries such as the southwestern in Bangladesh Sundarbans
, where the rich and productive ecosystems
provide the spawning grounds
for shrimp and fish.
Almost 100% aqua culture farm in Bangladesh is Organic and Natural.
In General Bangladeshi farmed shrimp is wild and natural.For Black Tiger during 1980’s about 95% fish spawn used to be collected from natural sources. but now it will be 70%. In general spawn Seed/larva Collect) from Bay of Bangle and Sundarbans
and it’s preserve in floodplains and Man Made Pond for some days (culture) to become good size and shape. All floodplains and ponds are situated beside sea or shore are and connected with Ocean directly by river and canal that’s why can exchange and full fill up with sea tidal water, so the environment is like Ocean
Different types of farming systems evolved from earlier ‘no-stocking’ subsistence shrimp farming. In case of Black Tiger shrimp, three farming systems can be identified based on the intensity of production:
a. Extensive Culture System
b. Improved Extensive Culture System
c. Semi Intensive Culture System
The majority of shrimp farms fall into the first two systems. These systems differ little fromeach other with regard to farm management practices such as pond preparation, occasionaluse of lime and fertilizer, separate sluices for flushing and drainage, nursing of PL in nurseryponds and use of screens in sluice gates to prevent predators.
Shrimp Farming Zone
Most of the firm are located on a coast and in mangrove areas. In the grow-out phase, the shrimp are grown to maturity.
The post larvae are transferred to ponds where they are fed until they reach marketable size, which takes about another three to six months. Bangladeshi natural floodplains act as nutrient-rich nurseries for a large number of larva and juvenile fish species and more rich than Sea water, so no additional food is needed. So our farmer not feeding them any.
Black Tiger Shrimp's Pond                                                 Fresh Water Shrimp's Pond
The tides provide for some water exchange, and the shrimp feed on naturally occurring organisms. Some area in Bangladesg found farmers grow wild shrimp by just opening the gates and inbound tidel water with wild larvae.
Generally Bangladesh has no bio & and hybrid shrimp. For Fresh Water shrimp farming is also natural, and our fresh Water shrimp is unique for it’s taste and quality.
Harvesting Black Tiger Shrimp's
Bangladesh have no Vannamei, It’s prohibited in Bangladesh by our government. As Vannamei is not our native species so our government prohibited it for assure the standard for our origin species. Although we are going behind to world competition due to lacking of vannamei, but it's the question of our own species quality and originate. I think everyone can understand the scenario how our govt is serious about our product quality and standard.
Others shrimp like Cat Tiger , Harina & White Prawn are 100% wild catching mainly from the Bay of Bengal and river.
Harvesting the shrimp is done by fishing them from the ponds using nets or by draining the ponds. Pond sizes and the level of technical infrastructure vary.
Harvesting Fresh Water Shrimp's
The World Bank and the Asian Development Bank financed projects to develop shrimp aquaculture in the 1980s. The Food and Agriculture Organization of the United Nations (FAO) has provided assistance to the shrimp and fishing industry in meeting fish safety and quality control standards based on the Hazard Analysis Critical Control Point (HACCP) approach.
