Native Trout Outlive Their Hatchery Kin The majority of fish caught by anglers come from natur al reproduction, even from lakes and streams in which hatchery ' fish have .been stocked, reports Edwin L. Cooper, fisheries biologist for the Agricultural Experi ment Station, the Pennsyl vania State University. Cooper says this statement is verified in a review of 164- world-wide studies of trout management, published un der the title “Trout Stocking as an Aid to Fish Manage ment,’’ Bulletin 663 of the Agricultural Experiment Sta- • ..." ; thrift by the dozen *t J«s 'rt - ■ For Poultrymen Who “NEED A LIFT” Eastern States Announces — Two New Cost-Cutting Poultry Feeds thriftmaker is a new complete layer feed which truly can deliver to your egg room “Thrift by the Dozen.” It offers you low, low cost per bag . . and 11 more thrift-making advantages, FOUR-MIX is a 44% protein supplement.

Essential differences be tween native trout popula tions and domesticated, hatchery trout should be recognized, Cooper feels. It is too much to expect hatch ery trout to survive in a na tural environment at the same rate as wild fish, in his opinion. Based on the large number of trials by different investi gators, he reports that re turns from hatchery trout are likely to occur when trout of any size are slocked in lakes, ponds, or streams where there is little or no competition from fish alrealy present, or when catchable - sized trout are stocked where steron 99 kills weeds that other weed killers find too hard to handle • • yet costs as little as 25$ an acre xt’s not what a 2,4-D costs—but what it controls that counts.

Trout lay many eggs, he points out and 400 young are a common, average brood ol fry. Oi these, he declares, only two need to live two years, the length of time re quired for'maturity, to main tain the original pair of stock fish. This' amounts to only one-half of one per cent survival. Opinions as to the type of trout management wanted by anglers range, he says, from “no stocking; fish for fun only” to “completely ar tificial propagation, putand take fishing ” Accurate ap praisals of the desires of the fishermen seldom are made, KIRKWOOD, PA.
