dc.description.abstract | The development of an inert food to replace live prey during the early stages of marine fish larvae requires research in different fields and therefore a precise work strategy. Our research on this subject has been carried out in successive steps using the gilthead seabream Sparus aurata. The first step was the design of a food particle that would be well accepted and ingested by free-swimming marine larval fish during the first developmental stages. We chose microencapsulation by polymerization of the dietary protein as the most appropriate method for making the particles; different types of microcapsules were made using a basic diet containing only the major dietary components. In the second step, our aim was to keep the larvae alive in a routine rearing system in 300-L tanks, using exclusively this kind of food, long enough to detect any changes in growth, survival, or anatomical and histological status of the larvae, in order to verify whether the technological changes were positive. The third step focused on diet formulation and searching for clues to inefficient assimilation and growth. The use of ‘in vitro’ digestibility techniques allowed us to detect the inhibitory effect of some diet ingredients on larval proteases and to determine more suitable sources of protein. We now have a microcapsule able to efficiently support growth and development of S. aurata larvae, at least during the first 2 weeks of life, although the larvae still need to feed on rotifers during the first 2–4 days of exogenous feeding. This microcapsule will make it possible to make advances in determining the specific nutritional requirements of larval fish. | es_ES |
