Observations of larval red king crab (Paralithodes camtschatica) survival and conditions in laboratory experiments for the Physiological Response of Commercially Important Crab Species to Predicted Increases in pCO2 project in Kodiak, Alaska from 2017-04-10 to 2017-07-08 (NCEI Accession 0292530)

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
