Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish
Fish and Fisheries, EarlyView.ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...

Relationship between fish size and otolith length for 63 species of fishes from the Eastern North Pacific Ocean [PDF]
, 2000 Otoliths commonly are used to determine the taxon, age, and size of fishes. This information is useful for population management, predator-prey studies, and archaeological research.

Fisheries Management and Ecology, EarlyView.ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Variation in the isotopic signatures of juvenile gray snapper (Lutjanus griseus) from five southern Florida region [PDF]
, 2010 Measurements of 18O/16O and 13C/12C ratios in the carbonate of juvenile gray snapper (Lutjanus griseus) sagittal otoliths collected during 2001–2005 from different southern Florida regions indicated significant variations in the ratios between Florida ...

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.

Influence of constant and periodic experimental hypoxic stress on Atlantic croaker otolith chemistry
Aquatic Biology, 2014 The chemical composition of fish otoliths may provide information on the environmental exposure histories of fishes if ‘vital effects’ on element incorporation are minimal.

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)
Fisheries Management and Ecology, EarlyView.ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to
