Challenges in Composite Fish Culture:

1. Water Quality Management: Maintaining optimal water quality parameters such as dissolved oxygen levels, pH, temperature, and ammonia levels can be challenging in composite fish culture systems. Poor water quality can lead to stress, disease outbreaks, and reduced growth rates in fish.

2. Feed Management: Providing the right feed in the correct quantities can be a challenge in composite fish culture. Different species of fish have varying nutritional requirements, and ensuring all fish receive adequate nutrition can be complex.

3. Species Compatibility: Selecting fish species that are compatible in terms of feeding habits, water quality requirements, and growth rates is crucial in composite fish culture. Incompatible species can lead to competition for food and space, resulting in poor growth rates.

4. Disease Management: Disease outbreaks can quickly spread in composite fish culture systems due to the close proximity of different fish species. Regular health monitoring, proper biosecurity measures, and prompt treatment of sick fish are essential to prevent disease outbreaks.

5. Harvesting and Marketing: Coordinating the harvesting of multiple fish species at different growth stages can be challenging in composite fish culture. Additionally, finding markets for diverse fish species can be a hurdle, especially if there is limited demand for certain species.

6. Infrastructure and Investment: Setting up and maintaining composite fish culture systems requires significant infrastructure and investment. Adequate pond construction, water supply, aeration systems, and feed storage facilities are essential for successful fish farming.

In conclusion, while composite fish culture offers several advantages such as increased productivity and efficient resource utilization, it also presents various challenges that fish farmers need to address to ensure the success of their operations. Proper management practices, regular monitoring, and adaptation to changing conditions are key to overcoming these challenges in composite fish culture.
