This has been very clearly demonstrated by the history of the lobster 
or oyster fisheries in Norway, Canada, Newfoundland, the 
United States, Holland, and France. Restriction to the verge 
of prohibition has failed ; and artificial culture has been re- 
sorted to. If it were possible for trawlers and fishermen to 
artificially fertilise the ova of ripe soles, turbot, brill, and plaice, 
and return the eggs to the sea, undoubted benefit would accrue, 
for the waste of spawn is enormous.* 
Hatcheries for sea fish have been established in the United States, 
Norway, Newfoundland, and at Grimsby, and it is proposed to 
erect one in Canada. If similar hatcheries were established on 
our coasts millions of young turbot, soles, &c, could be planted 
on proper ground every year. 
With this view the Fishery Board have recently requested Professor 
M 'In tosh to undertake an investigation into the hatching and 
development of the turbot and lemon sole. 
* All that is requisite is ajar of sea-water, into which the eggs are run by gentle 
pressure on the female ; a little milt is then added, and the contents gently stirred 
with the hand. After standing for a short time the contents should be flung into 
the sea.
