GILL NET SAMPLING STANDARDISATION IN LARGE RIVERS OF FRENCH GUIANA (SOUTH AMERICA).

Knowledge and Management of Aquatic Ecosystems, 2001
In this paper is analyzed the sampling efficiency of repeated batteries of mixed gillnets mesh size from 15 to 70 mm. The study was conducted in three French Guiana rivers : the Sinnamary, Comté and Malmanoury rivers.

Differential effects of freshwater browning across fish species: consequences for individual‐ to community‐level fish traits in north temperate lakes

Biological Reviews, Volume 101, Issue 1, Page 128-146, February 2026.
ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Hooking efficiencies of SMART drumlines and their possible deployment rates vs gillnets for bather protection

Frontiers in Marine Science
IntroductionFor 87 years, gillnets have been deployed off up to 51 beaches in New South Wales, Australia, to reduce bites on humans by white (Carcharodon carcharias), bull (Carcharhinus leucas), and tiger (Galeocerdo cuvier) sharks. Recently, to minimise

Mapping Mediterranean bentho‐demersal communities to better inform marine conservation

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Marine protected areas are one of the most common conservation tools being implemented worldwide to reach conservation targets, but their implementation does not usually take the heterogeneous distribution of bentho‐demersal communities into account.

Fisher Behavior While Illegally Fishing for Atlantic Goliath Grouper (Epinephelus itajara, Epinephelinae) on the Amazon Continental Shelf, Brazil

Fisheries Management and Ecology, Volume 33, Issue 1, Page 1-13, February 2026.
ABSTRACT In 2002, the Brazilian government banned fishing for Goliath grouper, Epinephelus itajara (Lichtenstein, 1822), through 2007. This grouper was the first fish species targeted by a specific law in Brazilian environmental legislation. Grouper stocks showed no signs of recovery, so the ban was renewed multiple times since 2007. Official estimates

Qualitative contrast comparisons of differently coloured gillnets.

, 1979
A regularly returning problem for Norwegian gill net manufacturers has been that fishermen often change their fancy for gill net colours, and also that fishermen from different districts have separate colour preferences. This necessitates production and. stocking of a great variety of differently coloured nets, and also creates peak demands for special

Discards monitoring in the Gillnet Sole Fishery

, 2011
The Gillnet Sole Fishery Study Group started discards monitoring. Data were supposed to be collected in three different ways: Self-sampling, catch monitoring by means of onboard cameras (CCTV) and monitoring under the Data Collection Regulation.

Detailed Insight into Gillnet Catches: Fish Directivity and Micro Distribution

Water
Gillnets are widely used in research and commercial fishery activities. As passive gear, gillnets can be selective and dependent on the diel migration of fish. In areas with limited littoral extent, inshore–offshore migration may cause bias in the gillnet catch.
