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.

Lessons from seabird conservation in Alaskan longline fisheries [PDF]

Conservation Biology, 2019
Abstract Although bycatch of seabirds and other long‐lived species is a critical conservation issue in world fisheries, case studies documenting significant reductions in the mortality of these low‐productivity species in a fishery are rare.

Sex and Size Influence the Spatiotemporal Distribution of White Sharks, With Implications for Interactions With Fisheries and Spatial Management in the Southwest Indian Ocean

Frontiers in Marine Science, 2022
Human activities in the oceans increase the extinction risk of marine megafauna. Interventions require an understanding of movement patterns and the spatiotemporal overlap with threats.

Fishing trip cost modeling using generalized linear model and machine learning methods - A case study with longline fisheries in the Pacific and an application in Regulatory Impact Analysis.

PLoS ONE, 2021
Fishing trip cost is an important element in evaluating economic performance of fisheries, assessing economic effects from fisheries management alternatives, and serving as input for ecosystem and bioeconomic modeling.

Vertical distribution of blue Shark (Prionace glauca) in The Indian Ocean [PDF]

E3S Web of Conferences, 2021
Each fish species tends to choose a suitable environment suitable for its survival and reproduction horizontally and vertically. Blue shark (Prionace glauca) is the dominant catch of pelagic sharks by-catch in the Eastern Indian Ocean longline tuna ...

Rights-Based Management, Competition, and Distributional Equity in Hawai‘i’s Largest Commercial Fishery

International Journal of the Commons, 2020
Many global fisheries have transitioned to rights-based management to improve bioeconomic outcomes, but several fishing communities have experienced negative social impacts.

The Challenges of Managing Depredation and Bycatch of Toothed Whales in Pelagic Longline Fisheries: Two U.S. Case Studies

Frontiers in Marine Science, 2021
Direct interactions with fisheries are broadly recognized as the leading conservation threat to small cetaceans. In open-ocean environments, one of the primary gear types implicated in these interactions is the pelagic longline.

Vulnerability of the Oceanic Whitetip Shark to Pelagic Longline Fisheries [PDF]

PLOS ONE, 2015
A combination of fisheries dependent and independent data was used to assess the vulnerability of the oceanic whitetip shark to pelagic longline fisheries. The Brazilian tuna longline fleet, operating in the equatorial and southwestern Atlantic, is used as a case study.

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 ...
