Abstract

<abstract abstract-type="main" id="are12077-abs-0001"> <title>Abstract</title> <p>Two experiments were conducted regarding the effect of poly‐β‐hydroxybutyrate (PHB) on the survival and development of Chinese mitten crab (<italic>Eriocheir sinensis</italic> Milne‐Edwards) larvae. Different PHB delivery approaches (particulate, enriched in filter feeding prey, or a combination of both) and feeding levels were applied to crab larvae from the zoea 2 (Z2) up to the megalopa stage. Bio‐encapsulation into rotifers and <italic>Artemia</italic> at a PHB dose of 100 mg L⁻¹ seemed an efficient approach to deliver PHB to the larvae and resulted in a significantly enhanced survival, development rate and osmotic tolerance. The results indicate that PHB should only be applied as a feed additive rather than as a food source, and that the availability of an adequate amount of nutrients seems to be of major importance for the PHB to induce these beneficial effects.</p> </abstract>
