Terms applied to young fishes 

 When a fish hatches from the egg, it has a small yolk sac filled with 

 nutriment. This persists for a longer or shorter time depending on the 

 kind of fish and the temperature of the water. In the case of the fishes 

 that spawn in late spring, the sac is 

 generally carried for a period varying 

 from three to ten days. During this 

 period the young fishes are termed 

 fry (Fig. i8o), and they require no 

 food other than that carried in the

they immediately begin to snap at 

 the minute organisms floating or swimming in the water. The young 

 fishes are then called advanced fry. When they reach the length of from 

 one and one-half to two inches, they become fingerlings, which term is 

 applied until they are one year old. 



Rate of growth 

 The temperature of the water and the amount of available food arc 

 two factors among others that influence the growth of a fish. If these 

 are favorable, then the rate of growth will vary with the species and 

 also with the individual. Any person who has watched the rearing of 

 a brood of young fishes has noticed the great variation in the size of
