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.

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 ...

Relative Impacts of Simultaneous Stressors on a Pelagic Marine Ecosystem

Frontiers in Marine Science, 2019
Climate change and fishing are two of the greatest anthropogenic stressors on marine ecosystems. We investigate the effects of these stressors on Hawaii’s deep-set longline fishery for bigeye tuna (Thunnus obesus) and the ecosystem which supports it ...

Sea Turtle Bycatch Mitigation in U.S. Longline Fisheries [PDF]

Frontiers in Marine Science, 2017
Capture of sea turtles in longline fisheries has been implicated in population declines of loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea) turtles. Since 2004, United States (U.S.) longline vessels targeting swordfish and tunas in the Pacific and regions in the Atlantic Ocean have operated under extensive fisheries regulations to ...

Killer whale depredation and associated costs to Alaskan sablefish, Pacific halibut and Greenland turbot longliners. [PDF]

PLoS ONE, 2014
Killer whale (Orcinus orca) depredation (whales stealing or damaging fish caught on fishing gear) adversely impacts demersal longline fisheries for sablefish (Anoplopoma fimbria), Pacific halibut (Hippoglossus stenolepis) and Greenland turbot ...

Horizontal and vertical movements of immature dusky sharks Carcharhinus obscurus in relation to commercial longline fisheries in the western North Atlantic Ocean

Animal Biotelemetry, 2021
Background Many species of sharks, including the dusky shark Carcharhinus obscurus, are often incidentally captured in commercial pelagic and bottom longline fisheries.

Bycatch Estimates From a Pacific Tuna Longline Fishery Provide a Baseline for Understanding the Long-Term Benefits of a Large, Blue Water Marine Sanctuary

Frontiers in Marine Science, 2021
Bycatch on pelagic tuna longlines has contributed to population declines in several far-ranging, oceanic species and presents a conservation challenge that area-based management tools are increasingly promoted to address.

Greenland shark (Somniosus microcephalus) feeding behavior on static fishing gear, effect of SMART (Selective Magnetic and Repellent-Treated) hook deterrent technology, and factors influencing entanglement in bottom longlines [PDF]

PeerJ, 2018
The Greenland Shark (Somniosus microcephalus) is the most common bycatch in the Greenland halibut (Reinhardtius hippoglossoides) bottom longline fishery in Cumberland Sound, Canada.

SHARK LONGLINE FISHERY IN TANJUNGLUAR-EAST LOMBOK

Indonesian Fisheries Research Journal, 2013
Studies on artisanal shark fisheries in Tanjungluar - East Lombok were conducted during the year 2001-2011 (except in 2003 and 2007). A sampling method called “rapid market survey” method was employed to collect catch data from surface and bottom longlines fishing, rapidly. Biological data and fisheries data were collected during survey. Catch data for

Review of dolphinfish biological and fishing data in Japanese waters

Scientia Marina, 1999
The dolphinfish (Coryphaena hippurus) performs seasonal migrations into adjacent waters of Japan, where it is exploited by several fisheries. The annual dolphinfish landings in Japan have tended to decrease in recent years.
