摘要:

Gulf killifish were maintained in either 3‰ or 35‰ commercial sea salts on a LD 12:12 photoperiod regime and sampled by heart puncture at one of 6 different times of day. Maximum titers of circulating prolactin occurred at the same time of day (8h after light onset) in fish acclimated to either 3‰ or 35‰. Fish acclimated to 3‰ had an additional increase in serum prolactin (8h after light offset) not noted in 35‰ acclimated fish.
