Deep-water fishing tactics of the Spanish fleet in the Northeast Atlantic. Seasonal and spatial distribution

Scientia Marina, 2011
The classification and identification of all the Spanish fishing activity targeting deep-sea species was conducted using a non-hierarchical classification technique designed for large matrices (CLARA).

Comparative assessment of eDNA metabarcoding and longline deployments for elasmobranch surveying across a large tropical marine park network

Aquatic conservation
Medium‐ to large‐scale marine protected areas (MPAs) are playing an increasingly important role in global marine biodiversity conservation. A key question is “how do we collect relevant data on biodiversity and population trends to inform their design ...

Analysis of the fishing effort of the Mexican longline tuna fleet operating in the Gulf of Mexico in 2004

Ciencias Marinas, 2010
The Gulf of Mexico yellowfin tuna (YFT) longline fishing effort for 2004 was analyzed. The data used to describe the longline characteristics and estimate the catch efficiency of the vessels (catch in number of organisms per trip) were obtained from ...

Interactions Between a Large Marine Protected Area, Pelagic Tuna and Associated Fisheries

Frontiers in Marine Science, 2020
The efficacy of large marine protected areas (MPA) for the conservation of mobile pelagic species is widely debated. Here, we quantified spatial and temporal trends in standardized catch per unit effort (CPUE) of two target pelagic species, yellowfin ...

Is it all about the haul? Pelagic false killer whale interactions with longline fisheries in the central North Pacific

Fisheries Research, 2020
Pelagic false killer whales (Pseudorca crassidens) are killed or seriously injured in the Hawai‘i-based deep-set longline fishery more than any other cetacean, with bycatch regularly exceeding allowable levels.

Study on the catch, bycatch and discard of Chinese pelagic longline fisheries in the Atlantic Ocean

Aquaculture and Fisheries
Catch, bycatch and discard information is important for the assessment and management of fisheries. Using Chinese pelagic tuna longline observer data from 2010 to 2018, we studied the catch composition in the Chinese pelagic tuna longline fisheries in ...

A sub-regional management framework for South Pacific longline fisheries [PDF]

, 2007
The principal objective of this study was to determine if additional net benefits can be derived from the sub-regional longline fishery by the introduction of a new management agreement that would centre on the provision of licensing arrangements that ...

At-vessel fishing mortality for six species of sharks caught in the northwest Atlantic and Gulf of Mexico [PDF]

, 2007
From 1994-2005 the Commercial Shark Fishery Observer Program (CSFOP) placed fishery observers aboard US bottom longline vessels engaged in directed fishing for sharks in the region from New Jersey to Louisiana, USA.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Comparative analysis of depth distribution for seventeen large pelagic fish species captured in a longline fishery in the central-eastern Pacific Ocean

Scientia Marina, 2012
The objective of this study was to estimate depth distribution of pelagic species captured in a longline fishery and to evaluate the difference in depth distribution among species.
