Fisheries and Climate Change in Tropical Rivers: Challenges and Adaptation Strategies: A Review (original) (raw)

2020, Journal of Fisheries and Life Sciences

Every ecosystem is affected by climate change day by day. The decline in fish catch in tropical rivers, changes in species distribution, spawning time, mortality, and loss of habitat, as well as falls in productivity in developing countries, is an alarming phenomenon that needs quick intervention. Tropical species are amassed differently across the various region, they also possess diverse life history physiologies and ecological communities. Thus, in contrast to polar and temperate regions, different responses to climate change might be exhibited by tropical species and their communities. This review provides a critical summary of the effect of climate change on fisheries in tropical regions and the current state of knowledge on the challenges faced. It discusses research priorities to understand better the ways of adapting to such challenges by browsing how species and ecological communities are acclimatizing to climate change in the most biodiverse places in such regions. Other strategies for managing climate change were also considered to be of relatively much importance. This paper suggests other important strategies for mitigating the effects of climate change, considering the social and economic outlays.
