Cetacean bycatch in Indian Ocean tuna gillnet fisheries [PDF]
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 ...

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 ...

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 (Gadus morhua) [PDF]
Animal WelfareThe 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)

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.
