Metabarcoding gillnets to assess unaccounted catch depredation or escape [PDF]

Environmental DNA, 2022
Gillnets are the world's most common net‐based fishing gear, comprising walls of light mesh designed to entangle fish. Gillnets are often retrieved with holes in the netting, which means some animals escape or are depredated unseen, but with some ...

Calibration of fish biomass estimates from gillnets: Step towards broader application of gillnet data

Ecological Indicators, 2023
Fish are an important component of aquatic ecosystems, thus representative and reliable assessments of their population variables are essential for a variety of ecological applications, management and conservation.

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 ...

Evidence of hawksbill turtle (Eretmochelys imbricata) depredation on fish caught in gillnets

Frontiers in Marine Science, 2023
Bycatch is a major global threat to marine megafauna and occurs in nearly all fishing fleets, including small-scale fisheries that use gillnets. Gillnets represent a threat to endangered air-breathing megafauna, who incidentally entangle in bottom-set ...

Experimental Mixed Gillnets Improve Catches of Narrow-Barred Spanish Mackerel (Scomberomorus commerson)

Fishes, 2023
A new gillnet made from multiple mesh sizes ranging from 125 to 180 mm of stretched mesh (experimental gillnet) was tested under commercial fishing conditions to compare the fishing performance with that of conventional gillnets with a 125 mm mesh ...

Effect of mechanical properties of monofilament twines on the catch efficiency of biodegradable gillnets. [PDF]

PLoS ONE, 2020
Gillnets made of the biodegradable resin polybutylene succinate co-adipate-co-terephthalate were tested under commercial fishing conditions to compare their fishing performance with that of conventional nylon polyamide (PA) gillnets.

Comparative selectivity of monofilament and multifilament gillnets for pearl mullet, Alburnus tarichi (Actinopterygii, Cypriniformes, Alburninae), in Lake Van [PDF]

Acta Ichthyologica et Piscatoria
Approximately 25% of annual inland capture fish production in Türkiye is from pearl mullet, Alburnus tarichi (Güldenstädt, 1814), which is an endemic species to the Lake Van Basin.

Does the monofilament nylon gillnets catch double more fishes than conventional multifilament gillnets in Danube delta: myth or reality

Scientific Annals of the Danube Delta Institute, 2017
The monofilament gillnets are prohibited by law for fishing in Romania. There is an untested myth among Romanian fishery stakeholders and folks that monofilament nylon gillnets have double times fishing catch than conventional multifilament gillnets ...

Effect of gillnet mesh size on the capture probability and capture patterns in the Asian paddle crab (Charybdis japonica) fishery [PDF]

Heliyon
In the Asian paddle crab (Charybdis japonica) gillnet fishery in the Yellow Sea, China, the minimum mesh size (MMS) regulation has been of a major importance due to high bycatch rates of undersized crabs. In this study, we evaluated how gillnet mesh size
