Methods are described for rearing turbot (Scophthalmus maximus L.) and brill (Scophthalmus rhombus L.) to late larval stages; the major part of the work was done on the former species. Turbot were reared to 16–0 mm and brill to 17–0 mm in length. Rearing tanks ranged in capacity from 8 to 60 1. Turbotlarvae hatched at 2–7–3–0 mm and successful first feeding was established on rotifers (Brachionus plicatilis) at a length of 3–6–3–8 mm; larvae were transferred to a diet of Artemia nauplii at 5–6—6–0 mm. Experiments on the effect of temperature on growth and yolkabsorption rates in yolksac turbot larvae showed optimal growth efficiency at 15–0 °C. Delayed initial feeding reduced subsequent survival. Drawings of larval development of turbot and brill were made as an aid to their identification in plankton samples.

Activities of digestive enzymes and main histological characteristics of the intestine were investigated in larvae of three salmonid species (Coregonus maraena, C. atterensis, Thymallus thymallus), of burbot (Lota lota), and pikeperch (Sander lucioperca) at the onset of exogenous feeding (0 day degrees (°d)) and at 250°d thereafter. At the onset of exogenous feeding the activities of proteolytic, lipolytic, and carbohydrate splitting enzymes were detected in the intestines of all species. The enzymatic activities showed significant species specific differences indicating specializations in functionality and digestion ability. In C. atterensis and L. lota the activities of most enzymes were low in comparison to the other investigated species and therefore their digestive system was only poorly developed. In S. lucioperca it was moderately developed and in T. thymallus and C. maraena well-developed. After 250°d, the activities of the investigated enzymes changed in a very species specific way. Histologically, the intestines of the investigated species revealed no species specific differentiations at the onset of the first feeding with the exception of the absence of goblet cells in L. lota and C. atterensis. These differentiated after 250°d.

Marine Rotifers

Pagrus auratus eggs were obtained from wild broodstock with naturally and artificially ovulated fish. Larvae were cultured for periods of up to 1 month on a diet of marine rotifers, Brachionus plicatilis. Small yolk-sac larvae hatched without functional eyes, mouth or digestive tract and for 3 days spent long periods at rest. Growth was initially rapid but slowed by 3 days as yolk reserves were nearing depletion. By Days 4-5, the mouth had opened, eyes were pigmented, yolk was depleted, and a rudimentary gut had formed. Larvae were now able to maintain a horizontal swimming mode and were actively searching for and attacking prey. First-feeding was observed in some larvae. Growth was retarded during the transition from endogenous to exogenous nutrition and then increased, probably as feeding proficiency improved with experience. Larvae starved from hatching did not survive for longer than 8 days.

Abstract Pikeperch, Sander lucioperca (L.) is a valuable species that is in high demand among consumers due to its nutritional features such as delicious meat, white and soft texture and lack of intermascualr bones. The main barriers in the development of pikeperch aquaculture are the challenges of its larviculture. A major problem in the larval period is that pikeperch must feed on live food, which imposes high costs on producers. Therefore, substituting live food with formulated diets is necessary, but this process cannot be performed easily and it requires an action plan to be successful. The aim of this study was to provide a brief overview of different aspects related to pikeperch nutrition including its natural feeding habits, nutritional requirements, digestive tract ontogeny, and the most common live foods used in pikeperch first feeding. Moreover, different weaning methods in pikeperch culture are provided to introduce an appropriate strategy to assist this fish in adapting to formulated diets.
