, 2016 In the Western Baltic Sea two genetically distinct cod stocks “Eastern Baltic cod” and “Western Baltic cod” occur with considerable mixing of stocks. In this study we evaluated the applicability of otolith shape analysis for classification of individuals

Archaeometry, EarlyView.ABSTRACT This study investigates the use of otolith shape analysis for species identification and size estimation in Ariopsis felis and Bagre marinus, based on 181 modern otoliths obtained from a scientific collection and recent sampling in the coastal regions of Campeche and Yucatán, as well as 39 archaeological otoliths corresponding to the Early ...

Listening in on the past: what can otolith δ18O values really tell us about the environmental history of fishes? [PDF]
PLoS ONE, 2014 Oxygen isotope ratios from fish otoliths are used to discriminate marine stocks and reconstruct past climate, assuming that variations in otolith δ18O values closely reflect differences in temperature history of fish when accounting for salinity induced ...

Fish and Fisheries, EarlyView.ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

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.

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

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.

FLUCTUATING ASYMMETRY IN THE OTOLITH WIDTH AND LENGTH OF ADULT TELEOST (Beryx splendens LOWE, 1834) (FAMILY: BERCIDAE) COLLECTED FROM THE ARABIAN SEA COASTS OF SULTANATE OF OMAN [PDF]
Croatian Journal of Fisheries, 2010 Fluctuating asymmetry was described for the otolith width and length of adult teleost Beryx splendens. The results showed that the level of asymmetry of the otolith width was the highest among the two asymmetry values obtained for the otolith of B ...
