Freshwater Fish Population Dynamics: A Study of the Effects of Environmental Factors on Fish Abundance and Distribution

Abstract

The exact design of the food processing organ in fish with varying feeding behaviors is still being better understood. To put it another way, there are many questions about how herbivore fishes differ from non-herbivore fishes in terms of the structural and functional changes they undergo to make use of the food in their environment. As long as the catchments are at least moderately fertile, it is safe to assume that the productivity will increase with the reservoir's catchment area. The reservoirs are mostly the result of hydroelectric or irrigation projects, and either boards of authority or irrigation/power agencies are the owners. Fisheries are typically seen as a secondary activity in these areas of water. The interests of the fisheries were not taken into consideration throughout the design and building phase because the majority of them were only regarded as fisheries resources after construction.
