12 Sibling intracohort cannibalism present day 9 to 15 post hatching 2-5% mortality Present Gisbert et al, 2000
13 Full yolk-sac resorption At onset of exogenous feeding (9 days post hatch), yolk sac reserves are not completely depleted from the cardiac stomach, suggesting a period of mixed nutrition. 9.0 °C * day Gisbert et al, 2000
14 Onset of exogeneous feeding 5-7 days 6.0 °C * day Gisbert et al, 2000
14 Onset of exogeneous feeding From hatch to 6 dph (days post hatch) growth was negatively allometric (b = 0.76), reflecting utilization of yolk for morphogenesis, growth, and metabolic energy 6.0 °C * day Gisbert et al, 2001
