A water temperature of 1°C can change profits.

Warm Fish Treasure is a next-generation heating film developed for aquaculture of fish and shrimp. Unlike traditional rod heaters, it adopts a surface heating method to reduce temperature unevenness in tanks and aquaculture ponds, achieving a uniform and stable rearing environment. In aquaculture, water temperature is a crucial management factor that significantly affects growth rate, feed intake, and survival rate. Warm Fish Treasure maintains a temperature difference of less than 2°C between the film and water temperature, preventing localized overheating, thereby reducing stress on aquatic products and supporting the creation of a healthy growth environment. Additionally, it achieves an electric heat conversion efficiency of over 98%, offering more than 30% energy savings compared to conventional electric heaters. With high corrosion resistance and waterproof performance suitable for seawater aquaculture, it can be used safely for extended periods. As a new heating solution for aquaculture that balances energy savings and productivity improvement, it contributes to the stable management of land-based aquaculture businesses.
