Impacts of climate change on different domains of fish hatchery operations concerning to productivity.
Domain of impacts | Species | Climatic variables | Specific impacts | References |
---|---|---|---|---|
Broodstock development | Carps | Flash flood and water quality deterioration | Huge mortality of broodfish in open-water | Deshwara (2017) |
Carps | Climate induced river siltation | Breeding ground destruction | Akhter and Rahman (2016) | |
Indian major carps | Rainfall and change in flood regimes | Reduced seed production in hatcheries | Vass et al. (2009) | |
Tilapia | Rising temperature | Occasions of egg collection from a tilapia brood have been reduced from 11 to 7 times | Haque (2009) | |
Breeding and spawning | Tilapia | Temperature | Poor spawning in both high and low temperature. Egg production declined at 33 °C and stopped at 35 °C | M. S. Hossan et al. (2013) |
Tilapia | Temperature | Growth performance of tilapia decreased after 34 °C and such tendency continued above this temperature | Rahman et al. (2021) | |
Common carp | Temperature | Negatively impacted different stages of breeding | Usman et al. (2015) | |
Hatching and larval development | Tilapia | Temperature | Temperature affects hatching and development of larvae | Hossain et al., 2021 |
Tilapia | Temperature | Increased water temperature (from 30 to 33 °C) significantly decreased larval development. | Faruk et al. (2012) | |
Climbing perch | Temperature | Manipulated temperature stimulated growth-related gene expression at juvenile stage | Ahammad et al. (2021) | |
Disease occurrence | Shrimp | Temperature | Temperature fluctuations caused disease outbreak in hatcheries | Ahmed and Diana, 2015a, Ahmed and Diana, 2015b |
Prawn | Fluctuation of pH, salinity, and temperature | Caused viral diseases in prawn and shrimp | Arcier et al. (1999) | |
Grass carp, Common carp | High temperature | Caused mainly viral and other microbial diseases | Cheng et al., 2008 | |
Impacts on economy | Fish hatchery of carp and other species | Storms, temperature fluctuation and erratic rainfall | Caused massive economic losses through adverse effects on breeding, hatching and nursing | Bhattacharjya et al. (2022) |
Brood fish of carp and other species | Heavy rainfall | Washed away of reared brood fish from fish hatcheries due to heavy rainfall driven flood | Bhattacharjya et al. (2022) |
