Summary Food consumption of newt tadpoles caught during July and August was estimated as C=34 W 1·11±0·12 where C is food consumption in milligrams wet weight/day and W is the live weight in grams. Well‐fed tadpoles assimilated the food with an efficiency of 90–6%, but at low rates of feeding, the efficiency fell. Gross growth efficiency was about 35 % at maximum rations.
