Effects of diet and aeration on the growth and metamorphosis of Rana tigrina tadpoles

The larvae of Rana tigrina were reared in isolation in the laboratory on five diets and with the oxygen supply increased by aeration. Best growth was observed with a mixed diet rich in protein, fat and carbohydrate, and metamorphosis took place in 20–46 days. A leafy diet, in addition to causing del...

Zusammenfassung:	The larvae of Rana tigrina were reared in isolation in the laboratory on five diets and with the oxygen supply increased by aeration. Best growth was observed with a mixed diet rich in protein, fat and carbohydrate, and metamorphosis took place in 20–46 days. A leafy diet, in addition to causing delayed metamorphosis and a slow rate of growth, resulted in body deformity. Aeration of the water enhanced the growth and rate of metamorphosis.
