Reducing sea turtle bycatch with net illumination in an Indonesian small-scale coastal gillnet fishery

Frontiers in Marine Science, 2022
Small-scale fisheries are economically and culturally important throughout the world’s coastal waters. These fisheries, however, often have high bycatch rates of protected marine species.

Assessment of Australian Sea Lion Bycatch Mortality in a Gillnet Fishery, and Implementation and Evaluation of an Effective Mitigation Strategy

Frontiers in Marine Science, 2022
Globally, the bycatch of marine mammals in fisheries represents the greatest source of human-caused mortality that threatens the sustainability of many populations and species.

Cetacean bycatch in Indian Ocean tuna gillnet fisheries

Endangered Species Research, 2020
Pelagic gillnet (driftnet) fisheries account for some 34% of Indian Ocean tuna catches. We combined published results from 10 bycatch sampling programmes (1981-2016) in Australia, Sri Lanka, India and Pakistan to estimate bycatch rates for cetaceans ...

Foraging activity of harbour porpoises around a bottom-gillnet in a coastal fishing ground, under the risk of bycatch.

PLoS ONE, 2021
Bycatch of harbour porpoises (Phocoena phocoena) by gillnets is a recognised threat to populations. To develop effective mitigation measures, understanding the mechanics of bycatch is essential.

Disentangling the causes of protected‐species bycatch in gillnet fisheries [PDF]

Conservation Biology, 2017
Abstract Gillnet fisheries are widely thought to pose a conservation threat to many populations of marine mammals, seabirds, and turtles. Gillnet fisheries also support a significant proportion of small‐scale fishing communities worldwide. Despite a large number of studies on protected‐species bycatch in recent decades, relatively few

High contrast panels and lights do not reduce bird bycatch in Baltic Sea gillnet fisheries

Global Ecology and Conservation, 2019
Bycatch is a cause of mortality among marine mammals, sea turtles, fish and birds. For some species this mortality may be sufficient to cause population declines.

Updated estimates of harbour porpoise (Phocoena phocoena) bycatch in the Danish North Sea bottom-set gillnet fishery

J. Cetacean Res. Manage., 2023
The bycatch of harbour porpoise in the Danish North Sea bottom-set gillnet fisheries between 1987-2001 is estimated using two methods involving extrapolation of observer data.

Management of gillnet bycatch of cetaceans in New Zealand

J. Cetacean Res. Manage., 2023
Bycatch of dolphins in inshore gillnets first attracted scientific and management attention in New Zealand in the 1980s. During 1984-88, 50-150 dusky dolphins were killed each year at Kaikoura in gillnets set at the surface to catch bait for rock lobster.
