Focus on small scale fisheries: drift gillnet fishery off Cochin, 1981 and 1982 [PDF]

, 1984
In recent years, the drift gillnet fishery has become one of the fast growing fishing methods in the coastal fishing sector because of its economic viability and selectivity for catching larger pelagics which find ready acceptance and consumer demand in ...

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.

Integrating Porpoise and Cod Management: A Comparison of Days-at-sea, ITQs, and Closures [PDF]

The purpose of this study is to determine if management measures based on effort reductions, in particular days-at-sea (DAS) controls, can approach a harbor porpoise individual transferable quotas (ITQ) program in terms of efficiency.

Discards monitoring in the Gillnet Sole Fishery [PDF]

, 2012
The Gillnet Sole Fishery Study Group monitored discards since 2011. This document describes results from the self-sampling. No observer trips in the Dutch Sole Gillnet Fishing have taken place under the EU data collection framework (DCF).

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

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’
