Answer» <p>Fish can be obtained by two ways : 1) Capture fishing it is the process of obtaining fish from natural resources. 2) Culture fishery : it is the practice of farming fishes. Farming can be done in both freshwater ecosystem ( which includes river water, pond water ) and marine ecosystem.</p><p>the answer of second question-An advantage of composite fish culture is that it increases the yield of fish. In a composite fish culture, five or six different species are grown together in a single fish pond. Fishes with different food habitats are chosen so that they do not compete for food among themselves. Also, this ensures a complete utilization of food resources in the pond. As a result, the survival rate of fish increases and their yield also increases.</p>
