Controlled Ghost Fishing: Effects of Soaking Times and Mesh Sizes on Catchability in Trammel Net Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Trammel nets are used with extended soaking times to increase the catching efficiency for demersal fish in commercial fishing. Long soaking time causes deterioration or damage to species caught in the first days. Effects of soaking time were investigated with 36‐mm, 42‐mm, and 46‐mm mesh sizes soaked over 1, 3, 5, and 7 days on target, non ...

Classification of European Illex coindetii and Loligo forbesii Squid Stocks by Trace Element Analysis of Statoliths

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT We investigated whether statolith microchemistry analysis could classify ommastrephid and loliginid squid species into fishery stocks. Statolith nucleus (early life stage) and edge (life stage at time before catch) of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) from various areas of the North East Atlantic Ocean and ...

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...

Conservation strategy insights for three protected Phengaris butterflies combining population genomics and landscape analyses

open access: yesInsect Conservation and Diversity, EarlyView.
Phengaris butterflies depend on specific wetland habitats, host plants and ant species, making them highly vulnerable and protected across Europe. Population genomics and resistance mapping combined to assess genetic structure and habitat connectivity in fragmented landscapes.
