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.

Murray-Darling basin freshwater shells: riverine reservoir effect [PDF]
, 2009 We report carbon isotope measurements on pre-bomb museum samples of freshwater mussel shells collected alive from riverine locations in New South Wales, Australia. The calculated reservoir ages, ranging from -60 to +112 years, are much smaller than those

Fisheries Management and Ecology, EarlyView.ABSTRACT Identifying efficient otolith subsampling strategies that maintain data quality for stock assessments is imperative given limited resources to meet age‐estimation demands of managed fish stocks. Our objective was to evaluate the performance of three different subsampling strategies: (1) fixed otolith subsampling, (2) proportional otolith ...

Otolith Chemistry Reveals Natal Region of Larval Capelin in Coastal Newfoundland, Canada
Frontiers in Marine Science, 2020 Identifying natal origins of animals is key to determining the relative productivity of natal habitats, dispersal of individuals among local populations (i.e., connectivity), and, ultimately, metapopulation dynamics.

Fisheries Management and Ecology, EarlyView.ABSTRACT We updated the stock status of Lutjanus analis, Lutjanus jocu, Lutjanus synagris, and Ocyurus chrysurus harvested along the Brazilian northeastern coast. Stock boundaries were defined according to the Marine Ecoregion classifications at a finer scale, to reflect the population structure of each species.

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 ...

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.

Validation of daily growth increments and estimation of growth rates of larval and early juvenile black skipjack, Euthynnus lineatus, using otoliths [PDF]
, 1993 ENGLISH: Increments in otoliths (sagittae) were examined, using light and scanning electron microscopy, to determine ages and estimate growth rates of larval and early-juvenile black skipjack, Euthynnus lineatus.

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.
