Otter trawling for fish is one of the world's most productive yet problematic fishing methods
due to its bycatch and discards; issues that have been mitigated in some fisheries by …

Knowledge of the size‐selectivity of fishing gear types is crucial to fisheries management
and ecology. The gillnet selectivity of most freshwater fish is poorly known. We caught 694 …

Fishing with experimental gill-nets was carried out during 1994 and 1995 off the western
coast of Portugal, using mesh sizes between 40 and 90mm. Most sets were concentrated in …

The selectivity of 3 trawl codends,(1) a commercially used standard codend,(2) a narrow
codend (100 meshes on its circumference instead of 200) and (3) a square mesh top panel …

The bottom-trawl fishery in Portuguese continental waters is a multi-species one targeting
benthic, demersal and pelagic fish, and cephalopods, where the blue whiting …

Weight/length relationships, condition factor, gonadosomatic and hepatosomatic indices,
conversion factor for gutted to total weight and spawning season of hake in the Portuguese …

This study reports the estimated relationships between body length and girths (head and
maximum) for 30 commercially important marine fish species from the Algarve coast …

Knowledge on selectivity is considered essential for an adequate management of the trawl
fishery. This paper compares the selectivity of conventionally used codends of 44 mm …

The feeding habits of the axillary seabream, Pagellus acarne (Risso, 1810), from the Gulf of
Tunis were investigated in relation to season, sex and fish size (juveniles TL< 14.5 cm and …

The aim of this study was to determine the selectivity of 40 mm square (40S) and 50 mm
diamond (50D) mesh codend for five species, red mullet (Mullus barbatus), annular sea …
