Observations of larval snow crab (Chionoecetes opilio) 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 2015-04-20 to 2016-06-13 (NCEI Accession 0259404)

In this study, we examined how CO2-driven acidification affected larval survival and condition in 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. Experiments on the effects of reduced pH on morphology; starvation survival; mass; and Ca, Mg, C, and N contents of the larvae were conducted in a design that fully crossed maternal treatment (pH at which the ovigerous females were held during embryo development) and larval treatment (which were the same 3 pH treatments). The complete methods, which should be read and understood prior to using this data, are under review as: Long, W.C., Swiney, K.M., Foy, R.J., 2023.
