In this study, we conducted comparative laboratory experiments on the environmental sensitivity of eggs and feeding larvae of Arctic cod, saffron cod, walleye pollock and Pacific cod. Experiments examined how variability in temperature and food availability influences growth, development, condition and survival at these early, critical life stages. These experiments take advantage of a new multi-species broodstock program at the Alaska Fisheries Science Center’s (AFSC) cold-water laboratory at the Hatfield Marine Science Center (HMSC). Both Arctic cod (Boreogadus saida) and saffron cod (Eleginus gracilis) play a crucial role in the region by channeling energy between plankton and higher level marine mammals and seabird in a moderately simple pelagic, ice-dominated food web. These CSV files are from laboratory experiments conducted from 2015 to 2016 on the temperature response of eggs and larvae of four ecologically important Alaskan gadids to determine how temperature affected a suite of vital rates in the egg and yolk sac larval stages, including growth, survival, condition metrics, and lipids. Data are presented as 10 CSV files: Time-0 eggs.csv Condition- Lipids.csv Condition-BD-SL.csv Survival-Cumulative mort LS ONLY.csv Survival-Survival Fraction ALL.csv Growth.csv Larval mortality schedule.csv Egg mortality schedule.csv Larvae time to starve.csv Egg mort and hatch.csv
