Using tickler chains to promote more environmentally benign trawls in an Australian penaeid fishery

Aquaculture and Fisheries, 2023
There has been an increasing emphasis on reducing the environmental impacts of penaeid trawls by modifying their anterior sections. In one Australian estuary, this approach has culminated in a new generic trawl comprising a slightly smaller mesh size ...

Determination of gill-net selectivity for King Fish (Scomberomorus Commerson, Lacepede 1800) using Mesh size in Sungailiat, Bangka Belitung Province

Revista Ambiente & Água, 2021
Selectivity is a fishing gear characteristic capable of catching fish of a specific size and species from the existing population distribution. Mesh size is one of the important factors that influence gillnets’ selectivity, because different length ...

Refining tickler chains for penaeid trawls

Aquaculture and Fisheries, 2022
Tickler chains are simple additions to the ground gears of benthic trawls that can improve the catches of some target species, albeit with considerable variability.

Collecting size-selectivity data for Antarctic krill (Euphausia superba) with a trawl independent towing rig. [PDF]

PLoS ONE, 2018
For the development of efficient trawls to minimize catch loss, escape mortality and potential negative ecosystem impacts from the fishery, the understanding about trawl selectivity processes are crucial.

Improving penaeid-trawl efficiencies via ground gear with tickler chains

Aquaculture and Fisheries, 2021
Penaeid trawls often have poor ecological efficiencies measured as unwanted bycatches (with high discard mortality) and

Toward elimination of unwanted catches using a 100 mm T90 extension and codend in demersal mixed fisheries.

PLoS ONE, 2020
Most European fishing fleets will need to drastically reduce their unwanted catches to comply with new rules of the common fisheries policy. A more practical way to avoid increasing on-board sorting time and issues linked to storage capacity is to ...

Investigating the Mesh Size Selectivity of Olive Flounder (Paralichthys olivaceus) Gillnets for Fisheries Resource Management in the East Sea

Fishes, 2023
This study aimed to evaluate the mesh selectivity of gillnets used in olive flounder (Paralichthys olivaceus) fishing by examining the distribution of total length (TL) across various mesh sizes.

Estimating the selectivity of unpaired trawl data: a case study with a pelagic gear

Scientia Marina, 2016
Most selectivity experiments employ either the covered codend or paired gear methods. It is not always possible, however, to use these methods. Owing to operational, biological and/or environmental considerations, there may be no obvious way or it may be

Increasing trammel mesh size reduces biomass removal, mitigates discards and increases economic revenue in artisanal fisheries

Frontiers in Marine Science
Small-scale fishing plays a major role in regional economies worldwide and, with a large number of small vessels involved, it provides employment and livelihood to coastal communities.
