Exploring fishing threat at fleet segment and subregional scale: Least expert knowledge and a resilience versus disturbance‐based approach as conservation's tools for cartilaginous fish

Ecology and Evolution, 2023
Based on an explorative but rigorous elicitation framework, we obtained the bycatch fishing probability at the fishing fleet segment level using expert estimates.

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

Fisheries 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 ...

Elasmobranchs small-scale fishery in Guatemala: Socioeconomic aspects and value chain structure

Social Sciences and Humanities Open
Small-scale fishing (SSF) stands as a cornerstone of economic activity along Guatemala's coastlines. Fisheries products, including those derived from elasmobranchs, serve as vital sources of income for fishers and dealers.

Artisanal elasmobranch fisheries of northwestern Baja California, Mexico

Ciencias Marinas, 2020
Elasmobranch species composition and spatiotemporal variability can often be characterized from landing surveys of local fisheries, with important management implications. In the present study, we describe the elasmobranch landing composition of 4 major

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

An informational summary on elasmobranchs in Elkhorn Slough [PDF]

, 1994
Shark angling derbies have been held in Elkhorn Slough since 1946, and archery derbies since about 1973. Elkhorn Slough is an important pupping and breeding area for leopard sharks, Triakis semifasciata, and bat rays, Myliobatis californica, and a ...

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Branchial localization of acid (A‐type) and base (B‐type) excreting ionocytes in Amazonian stenohaline freshwater Potamotrygon ray

Journal of Fish Biology, EarlyView.
Abstract The branchial epithelium of Potamotrygon—a member of the only strictly freshwater elasmobranch family Potamotrygonidae—was observed via immunohistochemistry, and two distinct forms of ionocytes were identified. The acid (A‐type) and base (B‐type) secreting cells with respective basolateral–apical localizations of Na+/K+‐ATPase–Na+/H+ exchanger
