Comparative Studies of the Thyroid Function in Teleosts of Tropical and Temperate Habitats

P. Y. FORTUNE 1

1 Department of Zoology, The University of Leeds; Department of Zoology, The University of Glasgow

1. Normal and thiourea-treated Phoxinus and Lebistes show a depression of thyroid activity by low environmental temperatures and stimulation by high.

2. Thiourea treatment affects the thermal range in both species.

3. Phoxinus shows a seasonal variation in thyroid activity, correlated with breeding periods. This is absent in Lebistes.

4. No effect of the thyroid on growth could be demonstrated.
