Biomass and abundance biases in European standard gillnet sampling. [PDF]
PLoS ONE, 2015 The European Standard EN 14757 recommends gillnet mesh sizes that range from 5 to 55mm (knot-to-knot) for the standard monitoring of fish assemblages and suggests adding gillnets with larger mesh sizes if necessary.

A global meta-analysis of gillnet bycatch of toothed whales: Mitigation measures and research gaps. [PDF]
iScienceSummary: Odontocetes are globally distributed and are foundational to the structure and function of marine food webs, and hence bycatch impacts from gillnet fishing need to be considered in the context of their conservation and population viability ...

Looming-eyes buoys fail to reduce seabird bycatch in the Icelandic lumpfish fishery: depth-based fishing restrictions are an alternative. [PDF]
R Soc Open Sci, 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

Evaluation of the influence of correcting for gillnet selectivity on the estimation of population parameters. [PDF]
PLoS One, 2023 Gill nets are a common sampling technique in inland and marine fisheries. However, gill nets are size selective and may result in bias estimates of population parameters.

Impact of gillnet soaking time on survival, stress physiology, and muscle quality in Atlantic Cod (<i>Gadus morhua</i>). [PDF]
Anim WelfThe aim of this study was to investigate the effects of gillnet soak time to gain a better understanding of fish welfare, mortality, stress, and quality (as measured as muscle haemoglobin) during experimental gillnet fishery of Atlantic cod (Gadus morhua)

Spatiotemporal distribution and fishing ground driving mechanism of swimming crab Portunus trituberculatus in Hangzhou Bay and its adjacent waters. [PDF]
Sci RepThe marine ecological environment of Hangzhou Bay and its adjacent waters ( 30°–31° N, 121.5–123.5° E ) shaped by various factors, serves as a spawning and feeding ground for diverse species of fish, shrimp and crabs, including a traditional gillnet ...

Comparison of fishing efficiency between biodegradable gillnets and conventional nylon gillnets [PDF]
Fisheries Research, 2019 Abstract Gillnets made of a new biodegradable resin (polybutylene succinate co-adipate-co-terephthalate (PBSAT) were tested under commercial fishing conditions to compare their fishing performance with that of conventional nylon (PA) nets. The relative catch efficiency between the two gillnet types was evaluated over the entirewinter fishing season ...

A TECHNICAL STUDY OF MODIFIED GILLNET IN KENDAL REGENCY WATERS [PDF]
Russian Journal of Agricultural and Socio-Economic Sciences, 2019 Gillnets are the fishing gear selected by Kendal fishermen particularly in small-scale artisanal fisheries because gillnets need relatively small capital, have easy operation, use medium- or small-sized fishing vessels, and are selective towards catches.

Applied Sciences, 2021 Although gillnet fisheries are increasingly common in Korea, few studies have conducted sea trials using tie-down gillnets. Here, we analyzed the mesh size selectivity using tie-down gillnets with four different mesh sizes (84, 90, 105, and 120 mm) to ...
