Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South Georgia. [PDF]

Conserv Biol
Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

Perceptions and attitudes of residents toward small-scale longline tuna fishing in the Galapagos Marine Reserve: conservation and management implications

Frontiers in Marine Science, 2023
Longlining represents a cost-effective fishing modality for catching tuna, but its use is contentious due to the unintended catch of endangered, threatened, and protected (ETP) species.

The impact of predation by marine mammals on Patagonian toothfish longline fisheries [PDF]

, 2015
Predatory interaction of marine mammals with longline fisheries is observed globally, leading to partial or complete loss of the catch and in some parts of the world to considerable financial loss.

Investigation of the Effects of Hook Size and Bait Type on the Catch of Whiting, Merlangius merlangus (Linnaeus, 1758) (Gadidae) in Bottom Longline Fisheries of the Black Sea

Aquatic Sciences and Engineering, 2021
This study was carried out along the Ünye coasts of the South-eastern Black Sea (Turkey), in order to investigate the effects of hook size and bait type on the catch of whiting, Merlangius merlangus (Linnaeus, 1758) (Gadidae) in the bottom longline ...

Selectivity of the longline system used by the Mexican fleet in the exclusive economic zone

Ciencias Marinas, 1998
The longline is the most common fishing gear used to catch pelagic fish species. It consists of a principal line or mother line from which secondary lines with hooks hang.

Pelagic longline gear depth and shoaling [PDF]

Fisheries Research, 2006
Temperature-depth recorders (TDRs) were attached to pelagic longline gear in the Hawaii-based commercial fishery to obtain actual fishing depths and to test the accuracy of catenary algorithms for predicting fishing depths. Swordfish gear was set shallow by typically deploying four hooks between successive floats.

Hauling Speed of Tuna Longline-I

NIPPON SUISAN GAKKAISHI, 1971
The present report showed the outline of hauling speed and the influence of catch and accident on it observable in the records collected from the hauling work of the 10 strings of tuna longline about at 155°E near the Equator conducted by the Choho-maru (266 gross tons), And the results obtained were summarized as follows: 1.

Relative abundance of pelagic sharks in the western North Atlantic Ocean, including the Gulf of Mexico and Caribbean Sea [PDF]

, 2007
Little information exists on the status of pelagic shark populations in the Atlantic Ocean, especially in the Gulf of Mexico and Caribbean Sea. We derived indices of relative abundance for pelagic sharks based on mandatory logbooks and observer reports ...

Deadweight anchoring behavior for aquaculture longline

Latin American Journal of Aquatic Research, 2020
The similarity theory was used to study the behavior of five anchoring and one "rezon" type deadweight designs, using scale models. The surface sediments extracted from Charagato Bay, Cubagua Island, were characterized to evaluate the efficiency of these models on these substrates.
