Characteristics of the shark fisheries of Fiji [PDF]

, 2015
Limited information is available on artisanal and subsistence shark fisheries across the Pacific. The aim of this study was to investigate Fiji’s inshore fisheries which catch sharks.

Estimating Cetacean Bycatch From Non-representative Samples (I): A Simulation Study With Regularized Multilevel Regression and Post-stratification

Frontiers in Marine Science, 2021
Bycatch, the non-intentional capture or killing of non-target species in commercial or recreational fisheries, is a world wide threat to protected, endangered or threatened species (PETS) of marine megafauna.

Fisheries Bycatch of Chondrichthyes

, 2017
This chapter reviews the current state of knowledge about global chondrichthyes bycatch, including how the combination of biological characteristics of these species and the impact of different fishing methods reflect their vulnerability to bycatch.

Adjusting time-of-day and depth of fishing provides an economically viable solution to seabird bycatch in an albacore tuna longline fishery

Scientific Reports, 2023
Marine megafauna exposed to fisheries bycatch belong to some of the most threatened taxonomic groups and include apex and mesopredators that contribute to ecosystem regulation. Fisheries bycatch is a major threat to the conservation of albatrosses, large

Evaluating the appropriateness of risk-based approaches to assess the sustainability of fishery impacts on seabirds

Endangered Species Research, 2023
Many seabird populations are declining, with fisheries bycatch as one of the greatest threats. Explicit risk criteria should be used to identify whether bycatch is a problem for particular species and fisheries, but these are often poorly defined.

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.

Looming-eyes buoys fail to reduce seabird bycatch in the Icelandic lumpfish fishery: depth-based fishing restrictions are an alternative

Royal Society Open Science, 2023
Bycatch in gillnets from lumpfish (Cyclopterus lumpus) fisheries is an important conservation issue in the north Atlantic, with up to 30 000 seabirds potentially killed each year. To date, no technical solutions exist to reduce the bycatch of seabirds in

The economic cost of seabird bycatch in Argentinean longline fisheries [PDF]

, 2012
SummarySeabird mortality in longline fisheries is believed to be an important cause of the reductions in many seabird populations worldwide, and results in reduced fishing efficiency and economic losses for fishing companies.

Focusing on the relevant probabilities in population assignment to identify and correct bias

The Journal of Wildlife Management, EarlyView.
Understanding and calculating conditional probabilities is essential to avoid misinterpretation of population assignment results. We demonstrate how to calculate conditional probabilities for assignments, identify the conditions under which the ability to assign individuals accurately is poor, and provide suggestions on how to mitigate these issues ...

Bycatch in Indian trawl fisheries and some suggestions for trawl bycatch mitigation

Current Science, 2022
Globally, trawl is the major fishing gear used in marine fisheries and in India, it contributes to more than onethird of the marine fish production. Trawl fishing has been critically evaluated from a sustainability perspective, especially analysing its bycatch composition.
