Best Practices for Assessing and Managing Bycatch of Marine Mammals

Frontiers in Marine Science, 2021
Bycatch in marine fisheries is the leading source of human-caused mortality for marine mammals, has contributed to substantial declines of many marine mammal populations and species, and the extinction of at least one.

Bycatch mitigation in the West Greenland lumpfish (Cyclopterus lumpus) fishery using modified gillnets

Royal Society Open Science, 2023
Bycatch in gillnets is a global issue and mitigation measures that balance target species catch rates, bycatch reduction and fisher support are scarce. In the North Atlantic lumpfish fisheries, bycatch includes marine mammals and seabirds, and there are ...

Estimating protected species bycatch from limited observer coverage: A case study of seal bycatch in static net fisheries

Global Ecology and Conservation, 2020
Fisheries bycatch represents a major anthropogenic threat to marine megafauna worldwide. To identify populations at risk, it is essential to estimate the total number of individuals removed from a population as bycatch.

A socio‐psychological approach for understanding and managing bycatch in small‐scale fisheries

People and Nature, 2023
Fisheries bycatch is the greatest threat to migratory, long‐lived marine animals. Addressing bycatch ultimately requires changing fisher behaviour, yet social and behavioural sciences are rarely applied to bycatch mitigation, with an absence of theory ...

Advances in Scale Assessment of Seabird Bycatch: A New Methodological Framework

Diversity, 2023
This paper presents a methodology for indirectly estimating the scale of seabird bycatch using existing data. The study focuses on five key species of ducks that winter in the Polish waters of the Baltic Sea and are highly susceptible to bycatch: Long ...

Genetic assignment of fisheries bycatch reveals disproportionate mortality among Alaska Northern Fulmar breeding colonies

Evolutionary Applications, 2022
Global fisheries kill millions of seabirds annually through bycatch, but little is known about population‐level impacts, particularly in species that form metapopulations. U.S.

Comparing Dynamic and Static Time-Area Closures for Bycatch Mitigation: A Management Strategy Evaluation of a Swordfish Fishery

Frontiers in Marine Science, 2021
Time-area closures are a valuable tool for mitigating fisheries bycatch. There is increasing recognition that dynamic closures, which have boundaries that vary across space and time, can be more effective than static closures at protecting mobile species

Marine mammal bycatch in gillnet and other entangling net fisheries, 1990 to 2011

Endangered Species Research, 2013
Since the 1970s the role of fishery bycatch as a factor reducing, or limiting the recovery of, marine mammal populations has been increasingly recognized.

Bushmeat and bycatch: the sum of the parts [PDF]

Molecular Ecology, 2007
AbstractIn many developing countries, the killing of wild animals for commercial purposes (the bushmeat trade) is a significant factor in the reduction of biodiversity, and probably represents a major threat to the survival of many more populations than we know. This includes marine species such as cetaceans, sea turtles and sirenians (‘marine bushmeat’

Why study bycatch? An introduction to the Theme Section on fisheries bycatch [PDF]

Endangered Species Research, 2008
Several high-profile examples of fisheries bycatch involving marine megafauna (e.g. dolphins in tuna purse-seines, albatrosses in pelagic longlines, sea turtles in shrimp trawls) have drawn attention to the unintentional capture of non-target species during fishing operations, and have resulted in a dramatic increase in bycatch research over the past 2
