Studies relating the populational structure of target species to operational and environmental variables contribute directly management fisheries in these resources. Therefore, this study aimed provide data on fishing ecology swordfish ( Xiphias gladius) caught by Brazilian longline fleet operating western Atlantic between 2010 2016. Generalized additive mixed models were used evaluate relation...

The Saleh Bay is one of the bays in West Nusa Tenggara utilized as grouper fishing ground. However, previous spawning potential ratio study, some species have been overexploited Bay. This study aimed to estimate status utilization with a catch per unit effort (CPUE) approach and spatio-temporal intensity grounds Data were gathered using fish landing data geo-reference ground used several method...

Fishery Observing System (FOS) was developed as a first and basic step towards fish stock abundance nowcasting/forecasting within the framework of the EU research program Mediterranean Forecasting System: Toward an Environmental Prediction (MFSTEP). The study of the relationship between abundance and environmental parameters also represents a crucial point towards forecasting. Eight fishing ves...

the catch composition of the bottom trawl fishery along the coasts of karataş was evaluated in the 2002-2003 fishing season. a total of 110 species were registered, the fishes showed the highest diversity (90 species) followed by 15 crustaceans species and 5 species of cephalopods. the highest catch per unit effort (cpue) value (66.8 kg h -1 ) was recorded in september when the fishing season w...

Southern Resident killer whales (SRKW, Orcinus orca) are a small, endangered population of fish-eating that inhabit coastal and inland waters the western United States British Columbia. SRKW have been in decline since 1995, with food availability, vessel disturbance, pollutants proposed as drivers their decline. We used 17 years sightings data from core summer habitat Salish Sea to examine tren...

Understanding the key factors influencing population dynamics of fish stocks requires knowledge their spatial distribution and seasonal habitat selection, but these spatio-temporal are often not explicitly included in ecological studies stock assessment models. This study standardized data sardine fishery-dependent catch-per-unit- effort (CPUE) from west coast Portugal using Bayesian hierarchic...
