Specific physiological and biochemical tests have shown that these two types of hormones are secreted by teleosts but not readily available (Olivereau 1967). (1) Thyroid hormone plays an important role in oxygen uptake. The term hormone was first used by Bayliss and Sterling. In 130-150 mm length of heteropneustes fossilis, this gland is 0.471.5 mm (Belsare 1974). They feed and grow in sea for 2 or 3 years, then enter the river and undergo metamorphosis to become adults.
