TADPOLES BECOME MENACE TO TROUT

EXPERIENCE IN HAWERA *>

(From Our Own Correspondent.) WANGANUI, To-day. At a social meeting of the Hawera Acclimatisation Society reference was made to the fact that a plague of tadP«? les bad been experienced, seriously affecting the operations of the society. The chairman said that in Messrs. Goodson’s and Tristram’s dams, the finest sheets of water the society had ever handled, the results lately had been very unfortunate. It was difficult to say what went wrong. Good results should have been yielded by both dams as they had had a spell. In Mr. Tristram’s there had been an unusually large number of tadpoles, which might have had something to do with the failure. Mr. F. Vincent, who had the fish in Mr. Tristram’s dam in his care, said that previously the trout had kept the frogs down. The last fry that were liberated after the dam had been given a spell were splendid. There were 25,000 of them. Three months after liberation there were no trout, but instead four full nets of tadpoles. From 70,000 to 100,000 were taken from the dam. These had probably starved the trout out. There were only about 80 fish left altogether.
