Effect of water temperature on embryonic development of yellowfin tuna was investigated. Eggs were incubated at different water temperatures: 22, 24, 26C (Experiment-1) and 28, 30, 32C (Experiment-2). Developmental condition was observed and the elapsed time from the 2 or 4 cell stages until hatching was measured. Hatching occurred at 18.58 h for eggs incubated at 32'C. Eggs incubated at 22T stopped development after the morula (late cleavage) stage. Experiment-3 was designed to examine the relationship between hatching time and the incubation temperature, and was expressed by two regression lines which intersected at 269:C.Journal
