Journal of Fish Biology, EarlyView.Abstract This study reports three cases of pigmentation disorders in Squalus acanthias from the Gulf of Venice. Two specimens exhibited spotless phenotypes, whereas one exhibited hypermelanism. Morphological assessments were conducted for two individuals, alongside genetic analysis of mitochondrial genes to determine phylogeographic relationships. Both

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).

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea
Journal of Fish Biology, EarlyView.Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

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 ...

Temporal Changes in a Tropical Nekton Assemblage and Performance of a Prawn Selective Gear [PDF]
, 1995 The temporal variation of components of a moderately diverse (H=1.46) tropical estuarine fish assemblage (long. 146°30'E, lat. 8°45'S) was directed by salinities that had been determined by local oceanographic and probably topographic conditions.

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).

A bioregional classification of the continental shelf of northeastern North America for conservation analysis and planning based on representation [PDF]
, 2007 Understanding how well National Marine Sanctuaries and other marine protected areas represent the diversity of species present within and among the biogeographic regions where they occur is essential for assessing their conservation value and ...

Journal of Fish Biology, EarlyView.Abstract Understanding fish behaviour and activity patterns is essential for interpreting their ecology and the processes that shape population dynamics, yet such information remains limited for wild fishes because observing individuals in situ is challenging.
