The influence of temperature on the stage at hatch of laboratory reared Gadus morhua and implications for comparisons of length and morphology
A staging table for yolk‐sac larvae of Atlantic cod Gadus morhua was developed and applied to determine the development stage at hatch. Larvae ( n = 20) were sampled during the period from 50% hatch to first‐feeding from four temperature treatments ( c . 2, 4, 8 and 12° C). Data recorded included st...
