We use for the first time whole‐genome sequencing to explore current and historical patterns of genetic diversity in European hake in the Northeastern Atlantic, focusing on the recently expanded distribution range in the North Sea. Genomic data revealed a complex scenario with three populations: North Sea, Celtic Sea and Portugal.

ABSTRACT Identifying efficient otolith subsampling strategies that maintain data quality for stock assessments is imperative given limited resources to meet age‐estimation demands of managed fish stocks. Our objective was to evaluate the performance of three different subsampling strategies: (1) fixed otolith subsampling, (2) proportional otolith ...

The Overlooked Threat of Global Warming on Elasmobranch Fertility
ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

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.

Anchovy Engraulis encrasicolus diet in the North and Baltic Seas
The diet of anchovy (Engraulis encrasicolus) in the North and Baltic Seas was studied using stomach analysis from four sampling events in different areas. Zooplanktivory was confirmed; the most frequent prey items (in over 40% of stomachs) were copepods, malacostracan larvae and fish larvae. In the Baltic Sea, Paracalanus spp.

Abstract The John Dory Zeus faber is a commercially exploited demersal fish species with a known distribution ranging from the Northeast Atlantic to parts of the Indian and Pacific oceans. A previous genetic survey using cytochrome c oxidase subunit I (COI) DNA barcodes suggested the presence of two geographically segregated taxonomic units within Z ...

Otolith Exchange Results Of European Anchovy (Engraulis encrasicolus) 2014
European anchovy (Engraulis encrasicolus) is a small pelagic species of high commercial importance in European waters, in both the Atlantic and the Mediterranean Sea. Ages reading on anchovy are important input data for the assessment and carried out by number of laboratories using international ageing criteria. The report on the latest workshop on age
