There are two main methods for raising adult redfish: semi-intensive pond culture and intensive indoor flow-through systems. Among these, the semi-intensive pond method is more widely practiced due to its cost-effectiveness and scalability.
First, wintering is a crucial phase in the production cycle. Redfish typically require around 12 months to reach marketable size, and proper wintering is essential to ensure their survival and growth during colder months.
Next, stocking is an important step. The recommended stocking density ranges from 300 to 600 fish per 15 hectares, with fingerlings measuring approximately 5 cm in length. Before stocking, the pond should be filled with water 1 to 2 weeks in advance. Fertilizer is usually applied once when the water reaches a depth of 30 cm, and again after the pond is fully filled.
If smaller fingerlings are used, they should be introduced when the water depth reaches 30 cm. As water temperatures increase, the water level can gradually be raised, and feeding should occur three times daily. If the stocked fingerlings are larger than 15 cm, it's important to maintain a sufficient population of plankton in the pond. If not, additional fertilizer may be needed to support the ecosystem. The ideal stocking temperature should be above 10°C to promote healthy growth.
Regarding feed, American redfish require a diet with at least 35% protein content, including over 12% fishmeal. To enhance palatability, some shrimp head powder can be added. Additionally, the size of the feed pellets should match the size of the fish to ensure efficient consumption and digestion. Proper feeding practices are key to achieving optimal growth and minimizing waste.
