Winter survival in wrasse - FC0110
|
Description
R&D
Summary objective:-
To investigate the winter physiological state of wrasse,
including the effect of temperature and slainity and
identify methods to improve their survival in winter through
the development of refuges.
Key customer purpose:-
To find suitable methods to ensure good overwintering
survival in wrasse used of the biological control of
sea-lice in salmon aquaculture. |
Objective
1) To compare survival and physiology of winter-caught
wrasse subjected to conditions of low temperature and low
salinity. Specifically:
a) To determine salinity and temperature survival thresholds
for corkwing and goldshinny wrasse, in order to compare
with values previously obtained for the same species tested
during the summer;
b) To examine the bllof chemistry of winter-caught wrasse,
and relate the results to the ability of wrasse to survive
winter conditions in the wild.
2) To design and test refuges in relation to improving
winter wrasse survival in Atlantic salmon netcages. |
