Iodine indirect effect on thyroid gland: structure and hormone receptor (TRα) in common sole, Solea solea larvae
Author(s): Mona M Mourad and Rania F Ismail
Abstract: The effect of feeding
Solea solea with
Artemia enriched in iodine during metamorphosis was evaluated. In the present study, three treatment groups were used; i) control fish fed with untreated
Artemia, ii) low dose (T
Low), in which sole were fed with instar Ó€
Artemia exposed to potassium iodate
® (0.1g IKO3/L) for 3 hours and iii) high dose (T
high), in which sole were fed with instar Ó€
Artemia exposed to potassium iodate® (0.2 g IKO
3/L
,). Growth performance, thyroid follicles (localization and morphometric analysis), and thyroid hormone receptor (TRα) were measured. A significant increase in the expression of thyroid hormone receptor type 1 (TRα) occurred in the iodine supplemented larvae and was 3.55±1.13 fold higher than the control. The thyroid gland was not significantly modified in the group fed on
Artemia supplemented with iodine; indicating that iodine-supplementation for sole post-larvae is unnecessary in open circuit seawater systems.
