tained, and, if necessary, reared and kept in ponds for the 
purpose. 
It is interesting to notice that Mr. Harald Dannevig 
has been experimenting with the fry of plaice in this 
manner at the Dunbar Hatchery of the Fishery Board for 
Scotland (see Fifteenth Report, p. 175, 1897), and has 
succeeded in rearing them through their post-larval stages 
until they had undergone their transformation into little 
plaice and settled on the bottom. 
In the Eleventh Annual Report (for 1896) of the Sea- 
Fisheries Inspectors for England and Wales, Mr. C. E. 
Fryer makes some interesting observations upon the 
results obtained by the artificial hatching of sea fish, 
especially in the hatcheries of Newfoundland and the 
United States. Upon some of these reports, and Mr. 
Fryer’s comments, I desire to make some further remarks. 
According to the Director of the Hatchery near Arendal, 
in Norway, about 300,000,000 Cod can be hatched for an 
expenditure of about £600, that is at the rate of a million 
for £2, or something over 2,000 young fish at the cost of 
ohe penny—a very moderate cost if even a few only of 
the fish grow to maturity, or if, by increasing the swarms 
of young fry, which must be eaten by their natural 
enemies, they so enable some of the (perhaps stronger) 
naturally hatched fish to escape destruction. 
Mr. Fryer’s comments upon the figures which he 
quotes in connection with the hatcheries of Newfoundland 
and the United States, rather give the impression that 
he is disappointed at the absence of more definite results, 
and that he feels that an absence of increase, or even a 
decrease in the fisheries, is not compatible with the claim 
that the addition of millions of artificially hatched fry to 
the sea must be a benefit to the local fisheries. But it is, 
perhaps, unreasonable to expect, as the Commissioner of
