Spatiotemporal and Environmental Effects on Demersal Fishes Along the Nearshore Texas Continental Shelf

Fishes
The goal of this study was to analyze data from a 10-year bottom longline survey to examine spatial, temporal, and environmental effects on demersal fishes along the Texas coast within the northwestern Gulf of Mexico.

Demersal fish community on the inner shelf of Ubatuba, southeastern Brazil

Brazilian Journal of Oceanography, 1998
Fluctuations in the distribution and abundance of demersal fishes collected by otter trawl on the continental shelf of Ubatuba were examined over a two-year sampling period, in an area up to 50 m depth. A total of 111 species were collected. Seasonal and

Contrasting population genetic structures of congeneric coastal flounders associated with different early life histories

Journal of Fish Biology, EarlyView.
Abstract Marine fish species are likely to exhibit little genetic differentiation among populations due to their high dispersal potential during early life stages and migratory nature. However, recent studies have increasingly reported intraspecific genetic differentiation resulting from species‐specific ecological traits, environmental factors, and ...

Assessing local adaptation and divergence at early life stages within Eastern Baltic cod (Gadus morhua)

Journal of Fish Biology, EarlyView.
Abstract Many commercially exploited fish stocks have declined over the last few decades. It is therefore essential to identify natural populations and understand local adaptation for sustainable management. Salinity is a key environmental factor shaping local adaptation, and adaptive trait divergence often occurs at the egg and larval stages.

Demersal Fish Community in the Near-Shelf Zone of the Cosmonaut Sea, Southern Ocean

Diversity
Studies on the demersal fish composition of the East Antarctic nearshore region are very scarce due to the harsh physical geography of the East Antarctic region, which is covered in ice and snow year round, leading to a scarcity of scientific surveys ...

Divergent exploratory‐avoidant behavioural strategies may drive niche differentiation in juvenile Antarctic fishes

Journal of Fish Biology, EarlyView.
Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Challenges in licensing the industrial double-rig trawl fisheries in Brazil

Latin American Journal of Aquatic Research, 2015
Bottom trawling is important in Brazilian fisheries and is currently highly multi-specific due to the overexploitation of the original targets; unselective fishing method; very large permitted fishing area and the country's high marine biodiversity ...

From occasional records to regular presence: Increasing occurrence of the bastard grunt Pomadasys incisus in the French Ligurian Sea (northwestern Mediterranean)

Journal of Fish Biology, EarlyView.
Abstract The bastard grunt Pomadasys incisus (Bowdich, 1825), an Atlantic teleost, has recently been recorded at multiple sites along the French Ligurian Sea. Three juveniles were captured in Villepey Lagoon, while several groups of sub‐adult and adult individuals were observed at Cagnes‐sur‐Mer and Monaco between 2020 and 2024.

Integrating environmental DNA, diving surveys and DNA barcoding to track endangered twaite shad (Alosa fallax) spawning sites

Journal of Fish Biology, EarlyView.
Abstract The twaite shad (A. fallax), an anadromous fish species belonging to the Clupeidae family, has experienced population declines throughout Europe. This decline is attributable to a range of anthropogenic pressures, including migration barriers, environmental pollution, habitat degradation, predation by invasive species and unsustainable fishing
