Effects of climate change on pelagic small fish in the coastal waters of China
Climate change continues to affect marine environments and has also altered marine fish communities and ecosystem stability.Pelagic small fishes,which are commercially important for Chinese marine fisheries,are sensitive to climate change.Although many recent studies have examined the impact of climate change on fish,there are relatively few comprehensive and systematic studies on the effect of climate change on pelagic small fishes.The current study summarizes the impacts of climate change on marine environmental factors,such as in-creases in seawater surface temperature,salinity,pH,dissolved oxygen and chlorophyll a concentration,sea level,as well as frequency of extreme events,in terms of the effect on pelagic small fishes.Development,habitat,migra-tion pattern,community structure,and resource abundance of pelagic small pelagic fishes are all impacted by these environmental factors and climate change.Pelagic small fish migrate to high-latitude oceans;shifts in distribution areas result in community structure changes,impacting fishery resources.This study investigates the effects of cli-mate change on marine fisheries to determine mitigation strategies.Such strategies help to establish a theoretical framework for the sustainable development of marine fisheries in the context of climate change.
