Digestive physiology of juvenile Dover sole - FC0106
|
Description
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. |
Objective
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.
