In this study, we examined how CO2-driven acidification affected larval survival and condition in red king crab (Paralithodes camtschatica), an important fishery species in Alaska. Experiments on the effects of reduced pH on morphology; survival; growth rate; mass; and Ca, Mg, C, and N contents of the larvae were conducted at 4 larval pH treatment. The complete methods, which should be read and understood prior to using this data, are under review and are published as a preprint as: Long, W.C., Gardner, J.L., Conrad, A., Foy, R., 2023. Effects of ocean acidification on red king crab larval survival and development. bioRxiv, 2023.2010. 2002.560246. https://doi.org/10.1101/2023.10.02.560246

In this study, we examined how CO2-driven acidification affected the embyro development and hatching of snow crab (Chionoecetes opilio), an important fishery species in Alaska. Ovigerous females were held in one of three treatments: ambient pH (~8.1), pH 7.8, and pH 7.5, through two annual reproductive cycles. Morphometric changes during development and hatching success were measured for embryos both years and calcification was measured for the adult females at the end of the 2-year experiment. The complete methods, which should be read and understood prior to using this data, have been published as: Long, W.C., Swiney, K.M., Foy, R.J., 2023. Direct, carryover, and maternal effects of ocean acidification on snow crab embryos and larvae. PLOS ONE 18(10), e0276360. https://doi.org/10.1371/journal.pone.0276360

This is data from a laboratory experiment in which snow crab juveniles were held at three different pHs (ambient, pH 7.8, and pH 7.5). Growth, survival, and morphology were recorded. The complete methods, which should be read and understood prior to using this data, are under review as: Long, W.C. (In Review). Ocean acidification reduces juvenile snow crab, Chionoecetes opilio, survival but does not affect growth or morphometrics.

This is data from a laboratory experiment in which red and blue king crab (Paralithodes camtschaticus and P. platypus) juveniles were held at three different pH levels (ambient, pH 7.8, and pH 7.5). Growth, survival, feeding and respiration were recorded. The complete methods, which should be read and understood prior to using this data are published as: Long, W.C., Pruisner, P., Swiney, K.M., and Foy, R. 2019. Effects of ocean acidification on respiration, feeding, and growth of juvenile red and blue king crabs (Paralithodes camtschaticus and P. platypus). ICES J. Mar. Sci. 76(5): 1335-1343. https://doi.org/10.1093/icesjms/fsz090.

This dataset contains the sample sizes and p-values for analysis of the size of juvenile Dungeness crab reared in ambient and high CO2 analysis compares the effect of CO2 within a single life-stage. The “Size Diff” is the average size of crabs rear in ambient CO2 minus the average size of crabs reared in high CO2. The “Percent Diff” is the percent difference between the ambient and high CO2 measurement.

A stage-structured pre-recruitment model for three species in the Eastern Bering Sea (snow crab, Tanner and red king crab) is parameterized using data from experiments on the effects of ocean pH and temperature on larval and juvenile snow, Tanner and red king crab. The model is then used to project eggs from hatching until they reach the first size-class in the models on which stock assessments are based (post-recruitment model). The pre-recruitment model is projected to 2100 under future projected time-trajectories of ocean pH, surface temperature and bottom temperature for locations chosen to be representative of the three species. The results of the projections are the expected time to achieve the first size-class in the post-recruitment model and the probability of surviving to this size-class, expressed relative to the time and survival probability for a reference period of 2006-2020

This dataset includes observations of how CO2-driven acidification affected the growth and survival of juvenile blue king crab (Paralithodes platypus.), an important fishery species in Alaska. Early benthic instar crabs were randomly assigned to one of three pH treatments: (1) surface ambient pH ~ 8.2, (2) likely in situ ambient pH 7.8, and (3) pH 7.5. Thirty crabs were held in individual inserts in each treatment for one year and checked daily for molting or death. The complete methods, which should be read and understood prior to using this data, are published as: Long, W. C., Van Sant, S. B., Swiney, K. M., and Foy, R. 2017. Survival, growth, and morphology of blue king crabs: Effect of ocean acidification decreases with exposure time.

This is data from a laboratory experiment in which blue king crab juveniles were held at three different pHs (ambient, pH 7.8, and pH 7.5) for a year. Growth, survival, and morphology were recorded.

Juvenile red and blue king crabs (Paralithodes camtschaticus and P. platypus) were exposed to three pH levels: ambient (pH 8.1), pH 7.8, and pH 7.5 for three weeks. Oxygen consumption and feeding ration were determined immediately after exposure to treatment water and after three weeks exposure. Growth can be calculated from the wet mass observations.

In this study, we examined how CO2-driven acidification affected the growth and survival of juvenile golden king crab (Lithodes aequispinus), an important fishery species in Alaska. Juveniles were reared from larvae in surface ambient pH seawater at the Kodiak Laboratory. Newly molted early benthic instar crabs were randomly assigned to one of three pH treatments: (1) surface ambient pH ~ 8.2, (2) likely in situ ambient pH 7.8, and (3) pH 7.5. Thirty crabs were held in individual inserts in each treatment for 127 days and checked daily for molting or death.
