Investigating the Dynamics of Sex‐Structured Stock Assessment Models Under Sexual Size Dimorphism

Fisheries Management and Ecology, EarlyView.
ABSTRACT The integration of separate sexes in stock assessment models represents an advancement towards more realistic modeling of interactions between fisheries and target species. However, increased model complexity can also introduce additional uncertainty into the modeling process.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

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.

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

THE EFFECTS OF DIFFERENT HANGING RATIOS ON CATCHING EFFICIENCY OF GILLNETS IN NORTHEASTERN TURKISH AEGEAN COASTS

, 2020
In this study, it was aimed to determine the effect of hanging ratio on the catch per unit effort in gillnets. The study was carried out at 0-30-meter depth in the Northeastern Aegean coast of Turkey between October 15, 2015 - October 15, 2017.

Navigating morphometric minefields: Modelling heteroscedasticity in length‐conversion models

Journal of Fish Biology, EarlyView.
Abstract A common problem when combining data on species' traits from multiple sources is that researchers often measure the same trait in different ways. For example, the length of a shark can be measured in a straight‐line or over‐the‐body, and for lengths that include the tail (e.g., fork and total lengths), with the tail in ‘stretched’ or ‘natural’

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 ...

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.
