Abstract:
We have investigated the effect of adaptation to low salinity water on the thyroid status of the euryhaline teleost, Sparus auratus. We show that, following low salinity adaptation, the plasma T(4) concentration increases and branchial deiodination activities of T(4), T(3), and rT(3) decrease. Moreover, branchial and hepatic enzyme activities that are putatively involved in thyroid hormone metabolism respond differentially in low salinity conditions. Our results indicate the involvement of thyroid hormones in Sparus auratus osmoregulation. Moreover, the gills appear well equipped to play an important role in the modulation of plasma thyroid hormone titers.
