      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.

      In composite fish culture, a combination of five or six fish species is used in a single fish pond. These species are selected so that they do not compete for food among them and are having different types of food habits. As a result, the food available in all the parts of the pond is used. For example, Catlas are surface feeders, Rohus feed in the middle-zone of the pond, Mrigals and Common Carps are bottom feeders and Grass Carps feed on the weeds, together these species can use all the food in the pond without competing with each other. This increases the fish yield from pond.

      Composite fish culture is a sustainable and efficient aquaculture practice that involves the simultaneous cultivation of multiple compatible fish species in the same pond. One of the significant advantages of composite fish culture is enhanced productivity through the utilization of different ecological niches within the pond. By introducing species that occupy different parts of the water column and have diverse feeding habits, the available resources are utilized more effectively. This results in higher overall fish production compared to monoculture, where a single fish species is cultivated in the same pond.
      Another advantage of composite fish culture is risk reduction. In monoculture systems, if one species faces disease outbreaks or adverse environmental conditions, the entire stock is at risk. In composite fish culture, the presence of multiple species creates a more resilient and balanced ecosystem. If one species faces challenges, the others may still thrive, providing a certain level of insurance against losses. Additionally, the combination of species with different food preferences can help maintain water quality by minimizing nutrient buildup and controlling the proliferation of unwanted organisms, contributing to a more stable and sustainable aquaculture system.
