Ocean and Coastal ResearchBycatch species are as important as target species in the challenge of comprehensive fishery management. This is especially the case for vulnerable species such as elasmobranchs in offshore areas of the Colombian Pacific Ocean (CPO), for which ...

Evolution and ecology of feeding in elasmobranchs [PDF]
Integrative and Comparative Biology, 2007 Paleozoic chondrichthyans had a large gape, numerous spike-like teeth, limited cranial kinesis, and a non-suspensory hyoid, suggesting a feeding mechanism dominated by bite and ram. Modern sharks are characterized by a mobile upper jaw braced by a suspensory hyoid arch that is highly kinetic.

Fish and Fisheries, EarlyView.ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.

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.

Elasmobranchs small-scale fishery in Guatemala: Socioeconomic aspects and value chain structure
Social Sciences and Humanities OpenSmall-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

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 ...

Journal of Fish Biology, EarlyView.Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Journal of Fish Biology, EarlyView.Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.
