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 As soon as the sac disappears,. sac. Fig. i8o.— Fry of brook trout 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 Name Common sucker Golden shiner.
