Morphological and chemical analysis of archaeological fish otoliths from the Lower Murray River, South Australia

open access: yes, 2012
We analysed otoliths from excavations along the Lower Murray River (n=24), dating from the mid- to late-Holocene period. We identified the species, and estimated the size and age of fish.

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

open access: yesFisheries 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.

Life-history of Lake Horowhenua common smelt: analysis of otolith chemistry and vertebral counts [PDF]

open access: yes, 2013
Lake Horowhenua is a coastal eutrophic lake on the west coast of the North Island. A recent survey of the lake found lower than expected fish diversity but comparatively abundant native fish populations, comprising mostly shortfin and longfin eels ...

Age and growth of larval Sardinella aurita (Pisces: Clupeidae) from northeastern Venezuela, determined by otolith microstructure analysis

open access: yesCiencias Marinas, 2006
Age and growth of Sardinella aurita larvae were analyzed based on daily growth increments in sagitta otoliths. Larvae were obtained from ichthyoplankton samples collected from the outer shelf off Margarita Island and from Mochima Bay (northeastern ...

Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the

Recent Anomalously Warm Ocean Conditions and Changes in the Migration and Spawning Distribution of Chub Mackerel (Scomber japonicus) in the Western North Pacific

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Extreme ocean warming has become increasingly pronounced in the western North Pacific in recent years. Coincident with this, both the egg abundance and the catch per unit effort (CPUE) of chub mackerel (Scomber japonicus) in fisheries targeting southward‐migrating adults have decreased.
