The fisheries' biodiversity consists of the physical and biological components which support the livelihoods of millions of people. With the growing population and with the changes in the modern world, there is an increase in the demand for fish protein which has led to more development of aquatic resources. Our main focus is to meet the needs and compelling demands of the market and to ensure growth that fulfills the needs of customers. We focus on providing the best fishery for tomorrow which will eventually help in the sustainable development of the ecosystem. There are a number of studies carried out to assess the fish diversity status in relation to hydrological and meteorological parameters in both spatiotemporal scales. The functional evenness and divergence of these catches have also altered in a substantial manner. The trends state that global fisheries are increasingly targeting species that play a major role within the marine ecosystem and underlining the importance of incorporating functional diversity in ecosystem management.
