Revisiting Maturity Data: Using Oocyte Diameter and Gonadosomatic Index to Retroactively Apply a New Maturity Scale to Greenland Halibut (Reinhardtius hippoglossoides)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Greenland halibut (Reinhardtius hippoglossoides) is a deep‐water flatfish which lives at temperatures of 1°C–4°C and produces large eggs (> 3 mm). The combination of low temperatures and large eggs has resulted in an unusual ovary development cycle, with vitellogenesis taking more than 1 year.

Widow rockfish: Proceedings of a workshop, Tiburon, California, December 11-12, 1980 [PDF]

, 1987
This workshop was organized because of the increase between 1978 and 1980 in coastwide landings of widow rockfish, from less than 1,000 mt to more than 20,000 mt, and because of scientists' concern with the lack of knowledge both of the fishery and ...

Habitat Suitability Modeling Predicts Two Migratory Groups of the Japanese Sardine, Sardinops melanostictus, in the Sea of Japan

Fisheries Oceanography, EarlyView.
ABSTRACT The Japanese sardine, Sardinops melanostictus, is a major fishery resource in the Sea of Japan (SOJ) and East China Sea (ECS); however, recent research on suitable habitats and migration patterns of this fish in these seas is lacking. We aimed to identify the oceanographic conditions (temperature, chlorophyll‐a concentration, and sea surface ...

Larval Transport Pathways Reveal Critical Habitat and Benefits of a Marine Protected Area to Fisheries

Fisheries Oceanography, EarlyView.
ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.

Growth Autocorrelation in Atlantic Bluefin Tuna Thunnus thynnus Larvae in the Northwest Mediterranean and the Gulf of Mexico

Fisheries Oceanography, EarlyView.
ABSTRACT Growth and survival rates during the early life stages are key vital parameters driving population dynamics of fish. Growth rates generally present a pattern of autocorrelation. Growth autocorrelation is stronger when faster and slower growing individuals continue to grow faster and slower.

Biological characteristics and mortality of western butterfish (Pentapodus vitta), an abundant bycatch species of prawn trawling and recreational fishing in a large subtropical embayment [PDF]

, 2006
The western butterfish (Pentapodus vitta) is numerous in the bycatch of prawn trawling and recreational fishing in Shark Bay, Western Australia. We have thus determined crucial aspects of its biological characteristics and the potential impact of fishing

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.
