Technology improves fish hatchery production in Bangladesh

Jessore district in southwestern Bangladesh is an important source of fish seed in the country. However, 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.
