Demersal Ichthyofaunal Assemblages in Mauritanian Deep-Waters

, 2017
A total of 2.7 million individuals and 191 tons of demersal fishes were caught at 283 trawling stations in Mauritanian waters, from 80 to 1860-m depth, during four scientific surveys. We identified 403 species belonging to 139 families . Great concentrations of families with low diversity were dominant up to 500-m depth off Cape Blanc, Cape Timiris and

Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

Journal of Fish Biology, EarlyView.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

Behavior of prey links midwater and demersal piscivorous reef fishes

Neotropical Ichthyology
Pelagic and demersal guilds of piscivorous fishes are linked by a variety of biological and physical processes that mediate interactions with common prey species.

Food intake of early juvenile western Baltic cod (Gadus morhua) during settlement transition

Journal of Fish Biology, EarlyView.
Abstract This study examines the gut contents of 203 early juvenile Atlantic cod [17–101 mm ± 18.48 mm standard deviation (SD)] from the Western Baltic Sea (ICES Subdivision 22) collected between 2020 and 2022. According to the observed prey (proportion of pelagic, intermediate and benthic items) in the cod guts, settlement transition from a pelagic to

Seychelles demersal fishery an analysis of data relating to four key demersal species

, 1992
Seychelles demersal fishery is described based on historic catch and effort data, and on biological studies of four key species: Batrican (Pristipomoides filamentosus), Job Gris (Aprion virescens), Bourgeois (Lutjanus sebae), and Maconde (Epinephelus chlorostigma).

Phylogeography of the widely distributed John Dory (Zeus faber, Actinopterygii: Zeiformes) reaffirms the prevalence of at least two deeply divergent clades

Journal of Fish Biology, EarlyView.
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 ...

Spatio-temporal trends in diversity of demersal fish assemblages in the Mediterranean

Scientia Marina, 2019
The high species richness, coupled with high proportion of endemism, makes the Mediterranean one of the world’s ‘biodiversity hotspots’. However, the continuous increase in fisheries in the last few decades has led to the overexploitation of their main ...

Reproduction and embryonic development of monkeyface prickleback Cebidichthys violaceus in captivity

Journal of Fish Biology, EarlyView.
Abstract Understanding the sequence of embryonic and larval development and the factors necessary to induce reproduction in captivity are critical for developing new species for commercial or conservation aquaculture. In this study, we describe the adult reproductive behaviours and development of eggs, embryos and early larvae of captive monkeyface ...
