How to obtain it. 123 
Salmonide. There is, however, this difference, that trout being 
retainable in fresh water ponds can be successfully cultivated by 
the individual, whereas salmon must be allowed to go to sea if 
they are to produce the highest results, and this renders individual 
action somewhat impracticable. By a well-directed system of 
co-operation amongst owners of fisheries, it is beyond any doubt 
that splendid results may be obtained. Of one point I have no 
doubt—that no investment would pay a much better dividend if 
properly managed. 
It has often been stated by scientists and others that only 
about one trout or salmon egg in a thousand deposited in our 
streams, produces a mature fish. This probably is not far from 
the mark. Anyhow, we are quite sure of one thing, and that is 
that the rule applies to over ninety-nine per cent. of the ova 
deposited naturally in our streams ; seventy-five per cent. of this 
loss probably occurs before the eggs are hatched and during the 
hatching period. It will be apparent at a glance, that by taking 
charge of the ova and actually hatching over ninety per cent. of it 
we are doing good work. It is necessary, however, that it be done 
properly, and that is just what has often not been done in the 
past, and cases of failure which the practised fish culturist could 
foresee, and which were inevitable owing to the means employed, 
have tended to bring fish culture into bad repute. Circumstances 
are entirely altered now, however, and the facilities which are 
provided for sowing good well-eyed healthy ova in our waters, will 
ere long produce good results if properly utilised. There are 
some individuals who still assert that fish culture is a failure. So 
there were those in years gone by who pronounced the steam 
engine a failure. Anything that is not absolutely perfect in all its 
details is pronounced a failure by a certain class of individuals, 
and probably always will be. Fish culture, however, as applied to 
the Sal/monide, has been proved by the results to be a great 
success, and I venture to say that in the future it will be stilk more 
so. It is now being successfully applied to the growth of other 
fish, both marine and fresh-water, and as information is gained by 
experience and difficulties are bridged over, its practical use will 
be found to be of great service in the management of-our 
fisheries.
