Nutritional regulation of egg production of Calanus finmarchicus in the North Atlantic

The proposed work is a combination of two projects: (1) An
examination of the role of food quality (C, N , fatty acids) in
influencing egg production of Calanus finmarchicus, using
ship-board experiments in which copepods are fed in situ food.
Experiments will be undertaken on Marine Productivity cruises in
spring and autumn. The work is proposed as a tied studentship.
(2) Complementary ship-board experiments in which copepods are
fed labelled tracers in food to examine the extent to which
Calanus can synthesise de novo so-called "essential" fatty acids.
Analysis of results will be underpinned by the quantitative
stoichiometry theory proposed by Anderson and Pond
(2000: Limnol Oceaogr 45, 1162-7).
