To study the
influence of diet composition on growth and feeding behavior in European
lobster larvae/juveniles (Homarus Gammarus)
under laboratory conditions .
lobster is a potential new species in aquaculture, however, knowledge of
nutritional requirements during juvenility is relatively low. No artificial
pelleted diet exist for this species, which is required for further
commercialized farming of this species
and knowledge about tailoring an optimal diet is therefore important.
have shown that during early ontogeny diets based on frozen krill are far
superior for survival and development of zoea stage (I-IV) larvae of European lobsters than other live
frozen feeds or artificial diets. In an experimental set up with lobster larvae and later juveniles kept in individual chambers, we will evaluate
possible differences in growth and feeding behavior by feeding pelleted/extruded/gelatinized
diets based on krill meal and compare
these processed feeds with frozen krill.
We will analyze various biochemical components of feeds, larvae and juveniles.
The results will gain important knowledge regarding future formulation of
artificial diets for this species.
