Anisakiasis is a gastrointestinal fishborne zoonosis caused by the ingestion of third stage larvae of the genus Anisakis. Between January and December 2013, 1112 specimens of four commercial fish species (Engraulis encrasicolus, Merluccius merluccius ...

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

Tissue effect on RNA:DNA ratios of marine fish larvae [PDF]
In some routine studies of larval condition based on RNA:DNA ratios, heads and/or guts are removed for further age and feeding analysis. Also, during capture larvae are often found with their eyes missing. In this work we analysed tissues effects (muscle,

The morphology, fine structure and spectral sensitivity of retinal photoreceptors of two anchovy species were investigated using light and electron microscopy and microspectrophotometry. Distinct regional specialisation of cones was observed. Long and short (bilobed) cones were observed in the horizontal retinal belt, including the nasal and temporal ...

Passive Gauze‐Based eDNA Sampler Proves Efficient and Cost‐Effective in the Marine Environment
Here, we present the first empirical comparison of the metaprobe 2.0, a low‐cost, passive eDNA sampler, against an industry standard Sterivex filtration method using dip‐collected 1‐L water samples (“water bottles”). Across 14 joint deployments, we assessed detection and quantification of eDNA of two elasmobranch and two teleost species. While Sterivex

Feeding of anchovy Engraulis encrasicolus larvae in the northwestern Adriatic Sea in response to changing hydrobiological conditions [PDF]
Results from depth integrated and vertically stratified plankton sampling in the northwestern Adriatic Sea were used for comparison of gut contents of larvae of European anchovy Engraulis encrasicolus with composition and concentration of potential prey ...

ABSTRACT The large estimates of mesopelagic fish biomass have long fuelled harvesting interests in the relatively untouched twilight zone of the ocean. The silvery lightfish—one of the most abundant species inhabiting the North Atlantic mesopelagic layer—is a candidate for such a fishery despite its enormous ecological importance and the insufficient ...

El solapamiento de la dieta del carite estriado Indo–Pacífico Scomberomorus commerson (Lac., 1802) y del pez sable Trichiurus lepturus (L., 1758) en la costa mediterránea egipcia [PDF]
The immigrant S. commerson (Lac., 1802) represents more than 2% of the total Egyptian catch and its distribution stretches from East to West along the Egyptian Mediterranean coast. The feeding habits of T. lepturus and S.

ABSTRACT In this study, we explored the population genetic structure and its relation to environmental adaptations of the dolphinfish (Coryphaena hippurus) in the western Atlantic Ocean and Mediterranean Sea. Although previously two populations within the Mediterranean Sea were identified, recent evidence suggests more complex structuring.
