Digestive physiology of juvenile Dover sole - FC0106

R&D Summary objectives:- Investigate the feeding and digestive physiology of juveile sole to enable the development and testing of diets suitable for the rearing of sole under laboratory conditions. Key customer purpose:- Provide direct support to Conway's sole ecology studies and enable MAFF to be aware of the potential future for commercial intensive culture systems.
1) Quantification of digestive enzyme responses to artificial and fresh feeds during the development of post-larval and juvenile sole, and assessment of the contribution of fresh diets to the level of enzyme activity in the gut. 2) Investigation of feeding rates and assimilation efficiencies in fish fed fresh and artificial diets. 3) Measurement of the energetic cost to the fish of digesting fresh and artificial diets. 4) Assessment of any diurnal variation of the above parameters, which would be relevant to the determination of optimal feeding regimes. 5) Methods of diet preparation to be refined, to provide diets with high stability in water. Stability to be tested by physical and chemical leach-loss trials. 6) Testing of diets with growth trials.
