When creating feeds for fish larvae and fry, nutritional requirements as well as the physical characteristics of feeds must be carefully considered. Physical characteristics are described by particle sinking rates, feed stability and nutrient leaching.
Together, nutritional and physical properties determine feed intake and digestion rates and are therefore essential for feed attractiveness. Feeds for larvae and fry are high value products. Therefore, yields from such products should be optimized. Depending on fish species, the feed conversion ratio (FCR) for hatchery feeds can be as low as 0.6:1.
Using the right feeding system to reach a precise, controlled and regular feed supply improves FCR values considerably.
However, even with the best feeding system, feed attractiveness remains crucial for success. Particularly larvae rely on chemicals emitted from feeds in order to initiate a search response that eventually leads to feed ingestion. Various substances, such as free amino acids, nucleotides, nucleotides and ammonium bases, improve feed attractiveness for fish.
