This dataset is from laboratory experiments that investigated the temperature dependence of swimming performance and behavioral characteristics of juvenile Pacific cod.

This dataset is from laboratory experiments that examined the direct effects of projected levels of ocean acidification on the eggs and larvae of walleye pollock.

This dataset is from a laboratory experiment examining whether marine fish embryos physiologically adapt to changing temperature environments.

This dataset is from a laboratory study that examined the growth responses of northern rock sole eggs and larvae across a range of CO2 levels to evaluate the potential sensitivity to ocean acidification.

This dataset is from a study examining the use of demersal and pelagic habitats in the southeast Bering Sea by age-0 Pacific cod, based on 4 years of demersal trawl surveys and 1 year of pelagic trawl surveys on the shelf, and 1 year of spatially intensive beam trawl sampling in a nearshore focal area along the central Alaska Peninsula.

This dataset contains data from a series of experiments that determined the upper thermal tolerance of early benthic stage red and blue king crabs. Experiments included determining the temperature at which 50% of crabs died after 24 hour exposure, determining the effect of temperature on feeding ration, and the effects of temperature on long-term growth and mortality.

This dataset is from a study examining the growth responses of juvenile walleye pollock at ambient and 3 elevated CO2 levels.

Annual growth increment patterns observed in the hard parts of many marine organisms are often related to factors in the physical environment, and investigators are increasingly using dendrochronology (tree-ring science) methods to explore these relationships. Dendrochronology techniques were applied to otolith growth increments in 3 flatfish species collected from the eastern Bering Sea: northern rock sole Lepidopsetta polyxystra, yellowfin sole Limanda aspera, and Alaska plaice Pleuronectes quadrituberculatus. Within each species, otoliths were visually crossdated to ensure that the correct calendar year was assigned to each growth increment. Growth-increment widths were measured in each otolith, crossdating was statistically checked, and a master chronology was generated for each species by averaging measurement time series after age-related growth declines had been removed. The 3 final chronologies spanned 18 to 20 yr and were significantly correlated with each other, indicating a high level of growth synchrony among species. Final chronologies were compared to annual and monthly climate variables, and were most strongly related to summertime eastern Bering Sea bottom temperatures.

Annual growth increment patterns observed in the hard parts of many marine organisms are often related to factors in the physical environment, and investigators are increasingly using dendrochronology (tree-ring science) methods to explore these relationships. Dendrochronology techniques were applied to the otolith growth increments of yellowfin sole Limanda aspera to determine the extent to which somatic growth and otolith growth are coupled. Otoliths were visually crossdated to ensure that the correct calendar year was assigned to each growth increment. Growth-increment widths were measured in each otolith, crossdating was statistically checked, and a master chronology was generated by averaging measurement time series after age-related growth declines had been removed. The final chronology spanned 43 yr and was significantly related to Bering Sea bottom temperature and sea surface temperature. The relationship between otolith growth and somatic growth was explored using regression analysis. Population-wide otolith anomalies were found to be significantly related to population-wide anomalies in body size, as indexed by fish weight-length ratios.

This data set describes the holding temperatures and developmental stages of larvae of red and blue king crab (Paralithodes camtschaticus and P. platypus) reared to the first crab stage at the Kodiak Laboratory.
