Lake Tahoe Trout (Salmo clarkii Tahoensis) 



The Auckland Society received 30,000 ova from Mr T. Russell 

 in 1878. About 3000 fry hatched out, but only 1000 survived. Of 

 these, part were placed in Lake Omapere, part in Lake Waikare, 

 and a few in the Onehunga Springs. No one has any knowledge 

 about them to-day ; they do not appear to have established themselves. 



There is some confusion about the identification of this fish and 

 the succeeding species. The name I have given above is that furnished 

 by Mr Ayson, Chief Inspector of Fisheries, who says that it is a 

 species which runs up to 20 or 30 Ib. weight in Lake Tahoe and other 

 lakes in the Sierra Nevada. He adds: "No other result could be 

 expected from these fish when turned out in water like Lakes Omapere 

 and Waikare, and the Onehunga Springs." 



Black-spotted Trout (Salmo henshawii) 



The report of the Auckland Society for 1885-86 states that ova 

 of this species were received from San Francisco, "which were reared 

 to maturity in the Society's ponds, producing fry, some quantity of 

 which was liberated. They either disappeared, or merged with the 

 Rainbow Trout." 



No one seems to have taken the trouble to look after the fish, 

 once it had been successfully introduced. 



* Californian Salmon ; Quinnat Salmon ; King Salmon ; Chinook 

 (Salmo quinnat; Onchorhynchus tschawytscha) 



The quinnat, like the brown trout, has been a great success in 

 acclimatisation work. The species is now thoroughly established on 

 the east coast of the South Island, and its range is being very steadily 

 increased. 



The Hawke's Bay Society was the first to take steps to introduce 

 this fish into New Zealand, and through Dr Spencer F. Baird, Chair- 

 man of the United States Fishery Commission, a shipment was 

 despatched to Napier in 1875. Unfortunately it never reached its 

 destination. The steamship having it on board went direct to Sydney, 

 and failing to obtain a fresh supply of ice there, it was found on the 

 trip to Auckland that the ova had begun to hatch out. To save them 

 from total loss, Mr J. C. Firth took a portion of the eggs and placed 

 them in the Auckland Society's ponds; the result was that out of 

 20,000 ova which arrived, about 10,000 were placed in the Waikato 

 and the upper tributaries of the River Thames. The remainder were 

 placed in the hatching-boxes; about 1450 fry were forwarded to the 

 Thames, Wairoa and Tauranga districts, though the loss, due to the
