New research developments in aquatic animal larval feeding and nutrition—recent literature Abstract excerpts compiled by Meredith Brooks, Hatcheryfeed marine-based diet when later challenged with the second vegetable-based diet. The data highlighted that positive effects were likely due to nutritional programming, and that this feeding technique can improve the use of plant material ingredients in feeds for Atlantic salmon.

Feeding n-3 HUFA rich diets to the larvae of the pink shrimp Farfantepenaeus paulensis increases stress tolerance and subsequent growth

Newly hatched Salmo salar

Early nutritional intervention can improve utilisation of vegetable-based diets in diploid and triploid Atlantic salmon (Salmo salar L.) This study explored using nutritional programming in Atlantic salmon during their early life stage to improve utilization of vegetable-based diets. Fry were fed either a marine-based diet or a vegetable-based diet for the first three

weeks; all fish were then fed the same commercial, marine-based diet for 15 weeks, and thereafter fed a second vegetable-based diet for an additional six weeks. Growth performance, feed intake, nutrient utilization and intestinal morphology were monitored, and results showed that fish initially given the vegetable-based diet had 24% higher growth rate and 23% better feed efficiency compared with fish fed the

This study investigated the subsequent growth performance of shrimp that were fed enriched Artemia during their larval phase. From mysis I to eight day-old postlarvae (PL8), Farfantepenaeus paulensis shrimp were fed either newly hatched Artemia nauplii or Artemia enriched with high levels of n-3 HUFA. Shrimp were exposed to salinity and total ammonia (TAN) stress tests at PL8, and those fed the enriched Artemia demon-
