The Itasenpara bitterling has an embryonic period up to 7 months, when the embryo experiences large seasonal temperature changes. We examined the temperature requisites for normal development during the embryonic stage. Fertilized eggs reared under any of the constant temperatures ranging from 5 degrees C to 30 degrees C did not achieve complete embryogenesis, and none reached the swim-up stage. The optimum temperature for normal embryonic development was found to be stage-dependent: 10-30… CONTINUE READING
