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.

Complex movements, philopatry and expanded depth range of a severely threatened pelagic shark, the oceanic whitetip (Carcharhinus longimanus) in the western North Atlantic. [PDF]
PLoS ONE, 2013 Oceanic whitetip sharks (Carcharhinus longimanus) have recently been targeted for conservation in the western North Atlantic following severe declines in abundance. Pop-up satellite archival tags were applied to 11 mature oceanic whitetips (10 females, 1

Visualizing the Food-Web Effects of Fishing for Tunas in the Pacific Ocean
Ecology and Society, 2004 We use food-web models to develop visualizations to compare and evaluate the interactions of tuna fisheries with their supporting food webs in the eastern tropical Pacific (ETP) and the central north Pacific (CNP) Oceans.

Spatial dynamics and expanded vertical niche of blue sharks in oceanographic fronts reveal habitat targets for conservation. [PDF]
PLoS ONE, 2012 Dramatic population declines among species of pelagic shark as a result of overfishing have been reported, with some species now at a fraction of their historical biomass.

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.

Submarine canyons as coral and sponge habitat on the eastern Bering Sea slope
Global Ecology and Conservation, 2015 Submarine canyons have been shown to positively influence pelagic and benthic biodiversity and ecosystem function. In the eastern Bering Sea, several immense canyons lie under the highly productive “green belt” along the continental slope.

Global seabird bycatch in longline fisheries [PDF]
Endangered Species Research, 2011 Bycatch in longline fisheries is believed to govern the adverse conservation status of many seabird species, but no comprehensive global assessment has been undertaken. We reviewed the extent of seabird bycatch in all longline fisheries for which data are available.

Frontiers in Marine ScienceDespite regulations aimed at curbing shark finning and bycatch, shark fishing mortality rates continue to escalate, partly due to unintended consequences of these policies which, along with illegal, unreported, and unregulated fishing and ghost fishing ...
