    ABSTRACT: A comprehensive aging study of vermilion snapper, Rhomboplites aurorubens, was conducted, using 1,465 otoliths collected between 1991 and 1995 from the commercial and headboat fisheries from North Carolina through the Florida Keys. An additional 19 otoliths came from fishery-independent samples from the South Atlantic Bight for fish smaller than 254 mm total length (TL), which is the legal size limit. Marginal increment analysis revealed that rings on the otoliths were deposited annually. This observation is further substantiated by the increasing modal radius of each age ring corresponding to the increasing modal size of the fish at age. Observed ages ranged from age 1 (202 mm mean TL) to age 14 (535 mm TL). The largest fish was 600 mm TL and was estimated to be age 13. The weight–length relationship was described by the equation: W = 9.55 × 10(L), where W = whole weight in kilograms and L = total length in millimeters. The von Bertalanffy equation was estimated using the inverse, weighted, back-calculated lengths at the last annulus. The equation was Lt = 650 (1−e ), where t is age in years.

    ABSTRACT: Species composition and gear competition for the small-scale fisheries in the Cyclades waters (off Naxos Island, Aegean Sea, Hellas) was studied based on samples collected during 1997–1998 with gill nets of different mesh sizes and longlines with hooks of different sizes. Comparisons used univariate and multivariate techniques based on species compositions by number and weight and the commercial/total catch ratio in terms of weight and number. The results of the various techniques were in agreement and suggested that the different gear/size/season combinations fall into two groups (all gill nets and all longlines), which differed from each other in terms of species composition, species diversity and dominance. In contrast, the commercial/total catch ratio did not differ either within and between gears. The implications of the results for the management of the Mediterranean fisheries resources are also discussed. # 2002 Elsevier Science B.V. All rights reserved.
