Survival probabilities of thornback skate (Raja clavata) and spotted skate (Raja montagui) discarded by tickler chain beam trawl, pulse trawl, and flyshoot fisheries. [PDF]
PLoS ONEWe measured discards survival probabilities of thornback (Raja clavata) and spotted skate (Raja montagui) in tickler chain beam trawling (5 trips, n = 183 for thornback skate, n = 137 for spotted skate), pulse beam trawling (9 trips, n = 94 for thornback

Using tickler chains to promote more environmentally benign trawls in an Australian penaeid fishery [PDF]
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 ...

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.

On the effect of tickler chain on the catches landed by a 55 ft. trawl net [PDF]
, 1965 The communication deals with the results of comparative tests conducted from Cochin base to study the effect of a tickler chain on the catches landed by a 55' shrimp otter trawl. The net was operated with and without chain and 82 hauls of 61 hours and 28 minutes total duration were made.

Experiments in fishing with shrimp trawls: on the standardisation of tickler chain [PDF]
, 1967 The communication deals with the results of experiments conducted off Gujarat coast for the standardisation of "Tickler chain" for shrimp trawls. Of the short link chains made of 3.2 mm, 4.8 mm and 6.2 mm rods the second was observed to increase the yield of shrimp in the net and without in any way adversely affecting the performance of the gear.

Catch comparison of pulse trawls vessels and a tickler chain beam trawler [PDF]
, 2011 Comparative fishing trials were conducted in May 2011 (week 19) on commercial beam trawlers fishing with conventional tickler chain beam trawls (on MFV GO4), pulse wings made by HFK-Engineering of Baarn, the Netherlands (MFV TX36), and pulse trawls produced by the DELMECO-Group of Goes, the Netherlands (version used on MFV TX68).

Trawling effects on biogeochemical processes are mediated by fauna in high-energy biogenic-reef-inhabited coastal sediments [PDF]
Biogeosciences, 2022 Dynamic, sandy environments are generally less vulnerable to mechanical stress compared to silty, low-energy habitats. Biogenic reef communities, however, may provide an exception to this.

Impact of bottom trawling on sediment biogeochemistry: a modelling approach [PDF]
Biogeosciences, 2021 Bottom trawling in shelf seas can occur more than 10 times per year for a given location. This affects the benthic metabolism, through a mortality of the macrofauna, resuspension of organic matter from the sediment, and alterations of the physical ...

Condition and survival of discards in tickler chain beam trawl fisheries
, 2020 Dutch demersal fisheries in the North Sea is a mixed fishery that mainly targets Dover sole (Solea solea) with plaice (Pleuronectes platessa), turbot (Scophthalmus maximus), brill (Scophthalmus rhombus) and other species as valuable bycatches. The fleet currently uses two gear types: pulse beam trawls and conventional tickler chain beam trawls.
