Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Revisiting Maturity Data: Using Oocyte Diameter and Gonadosomatic Index to Retroactively Apply a New Maturity Scale to Greenland Halibut (Reinhardtius hippoglossoides)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Greenland halibut (Reinhardtius hippoglossoides) is a deep‐water flatfish which lives at temperatures of 1°C–4°C and produces large eggs (> 3 mm). The combination of low temperatures and large eggs has resulted in an unusual ovary development cycle, with vitellogenesis taking more than 1 year.
