...Alaskan salmon life span is four to five years. Fish are hatched in fresh-water streams, spend two years there, then migrate .to open waters of the North Pacific, where they feed and grow. After swimming some 6,000 miles, they return to exact spot of birth...
...fishermen in hundreds of small boats hauled in one netful after another, the fat, red-flanked fish made the shallow water boil. Working two men in a boat round the clock, the fishermen collected as much as $1,000 apiece a day. Thus did the salmon come back last week to Alaska's Bristol Bay, one of the richest salmon-fishing grounds in the world, in the biggest run in the 49th state in twelve years...
Heartening Prediction. For Alaska fishermen, who had been hard hit by steadily diminishing runs in recent years, it was almost too good to be true. Some had glumly believed that intensive Japanese deep-sea fishing had ruined the Alaskan salmon runs for good. Others had taken heart from the forecast of a good run by Dr. William F. Royce. director of the University of Washington's Fisheries Research Institute. Royce keeps tab on the number of young salmon moving down the rivers and into the sea and watches the results of test catches throughout the northeast Pacific. Historically, Bristol...
...Harbor, Me., the 139-ft. "pogy" (menhaden) boat Rappahannock is fitted with a 52-h.p. compressor that delivers 196 cu. ft. of air at the pressure of 80 lbs. per sq. in. The idea is to shoot the air through perforated tubes sunk in the water near schools of fish. Curtains of bubbles rising from the perforations look to the fish like an impassable barrier and shoo them toward the Rappahannock...
When the bubble-bothered fish approach the Rappahannock, they will lose control of their swimming muscles. Pulses of electric current shot into the water from electrodes will make their tails wiggle rhythmically, steering them helplessly toward the ship. When they get close enough, the intake current of a powerful fish pump will suck them aboard. If this system works as the bureau hopes, it will revolutionize the business of harvesting fish that travel in dense schools...
