Fish growth research focuses on understanding the factors that influence the growth rate of fish species in aquaculture settings, natural environments, and fisheries. This research may involve studying the impact of environmental factors such as temperature, water quality, and food availability on fish growth, as well as genetic and nutritional factors. By understanding how these factors affect fish growth, researchers aim to optimize growth rates in aquaculture and fisheries, improve stock assessment methods, and ultimately enhance the sustainability and productivity of fish populations.
