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.

Evaluating the Sustainability of an Eastern Mediterranean Gillnet Fishery Based on the Catches of Undersized Individuals and the Reproductive Period of Targeted Species

Fishes
The catch composition of a coastal gillnet fishery in the Eastern Mediterranean Sea was analyzed through a two-year experimental fishing survey. Seven fish species occurred regularly in the hauls.

Early‐life temperature drives recruitment success in Eurasian perch (Perca fluviatilis) populations

Journal of Fish Biology, EarlyView.
Abstract Interannual fluctuations in the abundance of young‐of‐the‐year (YOY) European perch (Perca fluviatilis) were studied in two large French peri‐alpine lakes using a 12‐year dataset of late summer hydroacoustic surveys. Previous research has highlighted the importance of temperature.

Sawfish captures in the Queensland Shark Control Program, 1962 to 2016

Endangered Species Research, 2017
Within the Great Barrier Reef World Heritage Area in Queensland, Australia, lack of information on the distribution of sawfishes presents difficulty for informed management of their habitats and populations.

Marine heatwaves shape size‐dependent thermal exposure, habitat use and marine residency in Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Marine heatwaves (MHWs) are increasing in high‐latitude oceans, yet behavioural responses of anadromous fishes to these potential stressors during short marine feeding seasons remain poorly understood. We combined acoustic telemetry (internal temperature and depth) with satellite‐derived sea surface temperature data to quantify Arctic char ...

The effect of Hanging Ratio Factor on the catch amount of multifilament gill nets in coastal waters of Bushehr province, Persian Gulf [PDF]

بوم‌شناسی آبزیان, 2014
The aim of this study was to comparing the effect of different hanging ratios (E=0.5 and 0.6) of drift gillnets on catch rates, length composition and Catch per Unit Effort (CPUE) in Bushehr coastal waters between late September 2010 to late March 2011 ...

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

Nodular Lesions in the Pyloric Caeca of Sardinella aurita (Teleostei) Associated With the Cestode Anthobothrium sp. 1 Larvae (Platyhelminthes: Eucestoda) Off Tunisia, Mediterranean Sea

Journal of Fish Diseases, EarlyView.
ABSTRACT Examination of round sardinella Sardinella aurita Valenciennes, 1847 (Clupeidae) from the Gulf of Tunis (Tunisia) revealed the first local and Mediterranean record of Anthobothrium sp. 1 sensu Jensen & Bullard, 2010 (Tetraphyllidea incertae sedis, Anthobothrium).

Reproductive status of the swordfish, Trichiurus lepturus (Teleostei, Trichiuridae), exposed to small-scale fishing on the north coast of Santa Catarina state, southern Brazil [PDF]

Biotemas, 2009
The swordfish, Trichiurus lepturus, caught by small-scale fishermen from a community of southern Brazil was investigated based on 398 individuals landed from August 2006 to August 2007, aiming to evaluate in which periods and fishing techniques the ...
