World Hatchery Forum: Feeds, genetics and equipment for hatcheries Fifteen panelists presented recent developments in hatchery feeds, genetics and equipment for shrimp and fish at the World Hatchery Forum and how they can improve hatchery performance. Shrimp feeds: Simplicity, fast growth feeds and precision feeding “In the past, it was not impossible to condition broodstock without fresh feeds but in a commercial trial in Mexico, Skretting demonstrated that replacing most of the fresh feeds with a specialized broodstock diet led to the same results,” said Eamonn O’Brien, product manager at Skretting. Another aspect O’Brien highlighted is the wide variety of feeding protocols, feed sizes and also additives used in shrimp hatcheries leading to a lot of complexities in production and difficulties to standardize the outputs. He suggested the use of advanced, more sustainable and stable formulas that can help improve hatchery success, advocating for simplicity. As a case of success, O’Brien presented a trial Skretting performed in a commercial hatchery in Brazil testing a high-quality diet against an established cocktail mixture in Brazil. Results showed higher survival, less feed in use, and cleaner tanks, among other results. Ricardo Cedeño, specialist in shrimp farms at Cargill, also highlighted the importance of simplicity. He presented Cargill’s liquid feeds for shrimp, which
