  abstract = {{A}n experimental trawl survey was conducted in the {B}ay of {S}t {V}incent between {D}ecember 1984 and {A}pril. {I}n all, 85 hauls were performed during cruises. {T}he trawled fish represented 233 species and 59 families. {B}iomass and density estimates declined 13-fold between the first and last cruises. {T}his decline is not due to the survey catch (less than 2 % of the biomass of the bay), nor is it likely to be due to trawling-induced changes in habitat. {N}atural causes are the most likely reason for the decline. the #r$-type species (#{L}eiognathidae$, #{L}ethrinus nematacanthus$) had the largest population fluctuations, whilst longer living and later reproducing species (#{S}aurida undosquamis$, large #{U}peneus$ spp.) had the smallest. {T}rophic structure is studied using three expressions : number of species, biomass and density per trophic group. {N}umber of species per trophic group was the most insensitive to changes in time and place, with density being the most sensitive. {S}tudy of the variations in trophic structure could help with the monitoring of major changes in fish populations caused by fishing or environnmental changes.
