of the Field, who promptly forwarded them to the British Museum. Here 

 they were carefully examined and declared to be undoubted salmon, though 

 degenerated. 



A summary of the attempts to introduce this species of fish into 

 New Zealand waters is here given to show the continuous nature of 

 the effort. The total number of ova introduced during the last half- 

 century, beginning in 1868, was 4,813,000 or close on 5,000,000. In 

 addition, some iao,ooo eggs were obtained from pond-rearedl fish. 



The total number of fry liberated, at various stages of growth, 

 including those obtained from pond-reared fish, is approximately 

 2,620,000. These have been turned out into the following rivers or 

 their tributary lakes and rivers : 



Salmon Trout; Sea Trout {Salmo trutta) 



In 1868 the 'Celestial Queen' brought 1500 ova of sea trout to 

 Port Chalmers (on and May), but I cannot trace what came of them, 

 as to whether they went to the Society's ponds at Opoho, or to 

 Mr Duncan's ponds, which were on the Leith just above the mill. 

 If they were hatched it is probable that the fry got into Otago Harbour. 



In 1870 the Otago Society received some ova of this species from 

 Tasmania, and from it obtained 140 fry. These were liberated in a 

 pond communicating with the Shag River, except 20 which were 

 liberated in the Water of Leith. 



The early reports of the Southland Society are not obtainable, 

 but in a history of the Society recently (1916) compiled by Mr A. H. 

 Stock, it is stated that in 1870, " 154 ova were received from Tasmania 

 and hatched out well." These fry were retained in the ponds for
