Starter

Optimal starter feeds should have high crude protein and fat content tailored to the species' needs. Use the right particle size (crumble or micro pellet) and type (floating or sinking) specific to the species. Palatability is crucial for encouraging intake. Select feeds designed for the starter stage that deliver  rapid, healthy growth and minimize waste.

Before introducing fish into a grow-out pond or cage, keep them in nursery ponds or cages or use hapas. This way your fish are at the right density for optimal feeding. Use clean nets and check water quality, like temperature and oxygen. Recirculation systems need to be clean and the filter's bacterial population should be mature. Give the fish time to adjust to water temperature differences. Quality monitoring during transfer ensures fish are healthy and stress is minimized.

Count and check fingerlings before purchase by weighing or counting a fixed volume, like one cup, and averaging. Weigh batches to verify quantities and record details during counting. Alternatively, count fingerlings when releasing them into ponds or cages. Tracking fingerling quality during the culture period ensures better outcomes. Always be present during counting to ensure accuracy. 

Record keeping is essential to know how your fish are doing and where to focus. At De Heus we have designed a record keeping guide which helps you to calculate feed conversion rate (FCR), monitor growth and plan harvesting and feed purchase. When comparing your key data to benchmark you also know when there is an issue or where you can improve. Integrating quality monitoring of feeding, growth, and water quality into your records provides a complete picture for better decision-making.

As long as the water is clean, fish can stay healthy and grow well. Water quality parameters like oxygen levels, ammonia levels, and water temperature directly impact fish health and therefore feeding and overall performance. These parameters can change with environmental factors and feeding practices. Therefore, it is essential to regularly monitor water quality to maintain optimal conditions for your fish.
