Pacific halibut (Hippoglossus stenolepis) were reared from the egg stage through full yolk sac absorption. Fertilization success and egg and larval development were monitored. Forty percent fertilization was achieved and hatching success ranged from 15 to 40%. Eggs hatched between 312 and 434 hours at temperatures ranging from 5 to 7°C. At 6°C, the yolk sac was fully absorbed by day 55 from hatch. Salinity of neutral buoyancy was measured and estimates of the location of developing eggs and larvae in the natural environment were made.
