Popis:	1. 1. Histological examination showed that treatment with thiourea deactivated the thyroid gland in both freshwater (FW) and seawater (SW)-acclimated fish. 2. 2. FW acclimated fish treated with thiourea survived and showed no significant changes in serum osmolality or [Na + ]. 3. 3. SW-acclimated fish treated with thiourea survived less than 3 weeks and showed significant increases in serum osmolality and [Na + ]. 4. 4. SW-acclimated fish treated with thiourea and throxine survived until sacrificed and showed no significant changes in serum osmolality or [Na + ] compared to controls. 5. 5. It appears that a functional thyroid is essential for maintenance of [Na + ] and osmotic balance and for survival of Fundulus in SW.
