Title: Effects of rearing temperature on development and survival of embryonic and larval goldfish
Abstract: The effects of rearing temperature on a number of survival and development parameters were examined in goldfish. Females were induced to ovulate between 4 and 33 days after warming from 12°C to 20°C. Eggs were fertilized in a Tris-saline medium and incubated in moist air until eyeing at which time they were immersed in water. The optimum temperature for rearing eggs and larvae was 22°C. At 27°C and 17°C, there was a higher incidence of abnormal larvae at hatching and reduced larval viability compared to 22°C in some, but not all, experiments. Eggs incubated at 12°C produced inviable larvae. High proportions of 12°C larvae were abnormal at hatching and fish raised at 12°C failed to feed.
