CONCI^USION. 



It appears far from chimerical to assert that large canals and 

 reservoirs, constructed for supplying water for irrigation, offer 

 great possibilities for fish culture, if suitable species of fish be 

 used for stocking, and if spawning shallows be provided, and 

 the fry after hatching be prevented from escaping into the 

 ditches and laterals. 



Great facilities are being provided in dry belts of the country, 

 where native fish are usually scarce, for creating fish reserves 

 and establishing a fish-supply for sport, or even for commercial 

 purposes, and of guarding against the destruction of the fish 

 already occurring in the local lakes and streams.
