The age and growth of the blackspot seabream, Pagellus bogaraveo, were determined by examining sagittal otoliths from fish sampled in eastern Adriatic Sea. A total 674 specimens (181 males, 90 hermaphrodites, 108 females, 295 immatures) ranging 8.80 to 47.27 cm (21.93 ± 9.00 cm) length analyzed. maximum observed for whole sample was 13 years. dominated 1-year-old as a consequence an abundance j...
Abstract The lack of reliable fisheries statistics hampers full assessment the status marine resources. Central to this problem are data-poor such as Albanian seas and in particular SSF sector. present study aims portray small-scale fishery south waters based on daily onboard monitoring species catches during a two-year period (2016-2018). Results revealed total 6 11 fishing métiers for nets lo...
To understand better the growth mechanisms in the economically important fish Pagellus bogaraveo, in terms of muscle fibre hyperplasia v. hypertrophy, the lateral muscle of this fish was studied morphometrically from hatching to juvenile comparing rostral and caudal locations. Fish were sampled at 0, 5, 23, 40, 70, 100, 140 and 180 days. Fibre types were first identified by succinate dehydrogen...
A brief review of investigations carried out at IAMC-CNR Messina on the reproductive biology of farmed blackspot sea bream Pagellus bogaraveo, a new candidate species for aquaculture, is presented. Different aspects of sexuality, including hermaphroditism, gametogenesis, spermatozoal ultrastructure, maturity staging, seasonal development of gonads, and spawning in captivity, were studied. Prota...
Pagellus acarne is found in coastal waters worldwide and it includes important species of commercial recreational fisheries. In this study, 16 morphometric variables the sagittal otolith, including six characters, shape indices, four ecomorphological indexes, were investigated for first time among P. stocks collected from Aegean Marmara Seas coasts Turkey. Statistically significant differences ...
The study investigated growth, mortality and exploitation rate of Pagellus bellottii collected off Sierra Leone, aimed to support efficient management its stock. A total 8, 216 specimens were at random from January-November, 2016 on-board a demersal trawler. Data analysis employed methods implemented in the computerized FiSAT II software using pooled length-frequencies constant class size. Grow...
