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

open access: yesPLoS 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.

Cable length optimization for trawl fuel consumption reduction [PDF]

open access: yes, 2013
A numerical method for optimization of the cable lengths in trawls with respect to the ratio between the estimated trawl drag and the predicted catch efficiency is developed and applied.

Selectivity of Fishing Gear for Scomberomorus guttatus (Bloch & Schneider, 1801) Commodities in Pangandaran Fishing Ground, West Java [PDF]

open access: yes, 2020
Scomberomorus guttatus is a large pelagic fish commodity in Pangandaran Regency. It has the highest amount and production values, therefore it needs to be maximally utilized but remains its sustainability. The purpose of this research is to determine the

Enhanced algorithm for gear calculation for justified selection of materials of gears and wheels

open access: yesIzvestiya MGTU MAMI, 2014
This paper proposes a new improved algorithm for gear calculating allowing justified selection of sizes and heat treatment of the material for manufacture of gears and wheels, considering service life and operational mode. On the basis of the proposed algorithm, a program for gear calculation is developed.

Improving penaeid-trawl efficiencies via ground gear with tickler chains

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

Bioeconomic assessment of a change in fishing gear selectivity: the case of a single-species fleet affected by the landing obligation

open access: yes, 2017
The European Union Common Fisheries Policy has established a discard ban, which states that fish below a reference size cannot be sold directly for human consumption.

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

open access: yesScientia 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

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

open access: yesPLoS 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 ...
