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

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.

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 ...

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

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.

, 2020 Bottom trawls impact the seafloor and benthic ecosystem. To estimate the trawling impact, information is required about the dimensions of the gear that determine their footprint, sediment penetration depth and hydrodynamic drag that determines the amount of sediment mobilised in the wake of the trawl. Here we present the dimension of gear components of

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 ...
