Size selectivity of hooks in a Portuguese longline fishery targeting "red" sea breams (Pagellus acarne and Pagellus erythrinus) was studied. Experimental longlining was carried out with 3 hook sizes (numbers 11, 13 and 15; MUSTAD brand, round bent, spade end, Quality 2316 DT) and two baits (razor shell and ghost shrimp). A total of 33600 hooks were fished in 28 fishing trips. Pagellus acarne and Pagellus erythrinus dominated the catches along with two other sea breams (Sparidae): Diplodus vulgaris and Spondyliosoma cantharus. Species diversity was lower than in the previous "white" sea bream longline selectivity study (BIOECO/93/004), but catch rates were much higher; reaching 20-30% (number of fish per 100 hooks), with total catches of up to 60 kg per 1200 hook set. Biological studies of the two "red" sea breams were carried out. Age and growth studies using otoliths allowed the construction of age-length keys for both species and the estimation of growth parameters for P. acarne. Stomach content analysis was carried out in order to evaluate the feeding habits and diets of the two "red" sea breams.
