98 FISH CULTURE. 



Mr. Fry recommends a variety of matters, as the 

 flesh of coarse fish pounded small; and chiefly he 

 advises that the ova of various of these fish should 

 be procured and hatched, as the young fry wUl take 

 the embryo as soon as it appears with great avidity. 

 One of his reasons for preferring this food is cer- 

 tainly a very reasonable one, for he points out that it 

 is not likely to die and putrify, and there is not much 

 difficillty in obtaining large quantities of such spawn 

 or in hatching it, as very many of the coarse fish 

 are spawning from April to June, which is just the 

 period when this food is required; as the fish 

 increase in size other food can easily be substituted. 

 He also mentions the almost microscopic Crustacea 

 of the species Cythfere, Cyprus, and Cyclops, which 

 abound in stagnant waters, newly-hatched earth- 

 worms, &c. &c.
