Acoustic deterrence to facilitate the conservation of pantropical spotted dolphins (Stenella attenuata) in the Western Pacific Ocean

Frontiers in Marine Science, 2022
Commercial fishing constitutes an important food source but induces undesirable bycatch on animals worldwide. This study extends bycatch research geographically to the Western Pacific Ocean, filling a knowledge gap regarding bycatch and mitigation ...

The bycatch composition of shrimp trawl fishery in the Oman coastal waters, the Arabian Sea [PDF]

Acta Ichthyologica et Piscatoria, 2015
Background. Shrimps are one of the most valuable marine resources of Oman and shrimp fisheries is greatly contributing to the national economy, and sustainability of traditional fisheries villages. However, the shrimp trawl fishery has one of the highest

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.

Teaching fisheries bycatch: Exploring economic and behavioral drivers of bycatch through a classroom game

Agricultural and Resource Economics Review, 2022
AbstractThis paper presents a pedagogical exercise to explore the economics of price-based fisheries bycatch. In the exercise students experience the economic incentives that lead to bycatch due to highgrading; the discarding of low-value fish. We first discuss existing fisheries economics pedagogical activities and how our exercise is distinct.

Assessing incidental bycatch of seabirds in Norwegian coastal commercial fisheries: Empirical and methodological lessons

Global Ecology and Conservation, 2015
With diminishing seabird populations and little knowledge on incidental bycatch in fisheries in the Northeast Atlantic, this study aimed to screen seabird bycatch in Norwegian coastal fisheries in 2009. The purpose was to 1) quantify magnitude of seabird

ICHTHYOFAUNA BYCATCH OF THE ARTISANAL FISHERY OF PENAEID SHRIMPS IN PERNAMBUCO, NORTHEASTERN BRAZIL

Boletim do Instituto de Pesca, 2019
The shrimp trawl fisheries are highly efficient in capturing target species but is an unselective gear that commonly catches untargeted organisms, which are usually discarded due to their small size or no commercial value. To understand and, eventually,

Fisher-based assessments of sea turtle bycatch in small-scale fisheries in Pacific Mexico

Endangered Species Research
Reducing bycatch of sea turtles and other protected species in artisanal fisheries depends on first understanding where, how, and to what extent bycatch is occurring. We implemented rapid bycatch assessments (RBAs)—i.e.

Bycatch in the Maldivian pole-and-line tuna fishery.

PLoS ONE, 2017
Tropical tuna fisheries are among the largest worldwide, with some having significant bycatch issues. However, pole-and-line tuna fisheries are widely believed to have low bycatch rates, although these have rarely been quantified.

Questionnaire surveys to investigate marine mammal fisheries bycatch: systematic review and best practice

Frontiers in Marine Science
Bycatch is the most significant threat to marine mammals globally. There are increasing requirements for national governments to fulfil their obligations to international agreements and treaties to assess fisheries catch and bycatch of non-target species.

Bycatch of northern fulmar (Fulmarus glacialis) in Norwegian longline fisheries: Assessing spatiotemporal variations in scale and risk to improve management

Global Ecology and Conservation
Seabirds are vulnerable to bycatch in longline fisheries but for most species the impacts are largely unknown. To address this knowledge gap, studies can estimate bycatch directly using observations or calculate the theoretical risk of bycatch using ...
