Impact of Dietary Variations on Kuruma Shrimp (<i>Penaeus japonicus</i>) Assessed through Individual-Based Rearing and Insights into Individual Differences

Abstract

This study developed an individual-rearing method to compare the effects of live feed (sandworms Perinereis aibuhitensis), formulated pellet diets, and a mixture of live feed and formula feed on the Kuruma shrimp Penaeus japonicus, aiming to minimize the influence of non-dietary factors on the growth of P. japonicus, like cannibalism. Results indicated that live feed, with its higher protein, essential amino acids, and fatty acid content, led to significantly better growth and feeding performance in P. japonicus (p Vibrio and Photobacterium while decreasing Shimia and Rhodobacterales (p p P. japonicus, contributing to improved feed selection, development, and feeding strategies.
