The' goal is more fish in the creel at less cost. roducing stock, the sariie as leef cattlemen are," said Alex Calhoun, chief of the Inland Fisheries Branch of the Department of Fish and Game. His department plants fish by the million. with the scientific breeding operations livestock men use." From the UC viewpoint, Dr. Graham Gail, a geneticist in the UCD.. Animal Science Department, said, "Fish and cattle are vastly ; different, obviously, but the basic genetic principles of selection and mating are not so are trying to determine · vhich Uofl tmgerlings The overall pro they are' capable of producing.

Since the campus has no facilities for fish breeding, animal scientists will use fish in the state's hatcheries, but draw on scientific talent and research laboratories at Davis. One of the first joint efforts -a:sample crossing of two of the state's four rainbow,trout breed ing lines--has produced a hybrid that achieves catchable size of .about seven inches in 10 months, 30 days ahead of either jarent line. This means thai nore fish can be produced in less time, saving considerable costs of feeding arid handling -^costs 'which mount toward the end of the raising period as fish get larger. Quick growth is only one goal. Studies are being made of brood- stock fish to find individuals which produce: Large amounts of highly fertile eggs .so less weeding stock is needed; eggs )f larger size, which presiim ably will produce larger, stronger fingerlings; and fish, particularly fingerlings,. which will iave high surivial after planting- 'Gains in these objectives' also lave been achieved with the first hybrid crosses, Gall reported. Calhoun sSid. the Inland Fisheries conducts' three, kinds .0 stocking..There.js a "catchable program in which fish are planted in heavily fished streams am lakes; catches run 60 to 90 per cent. within days or "weeks ol planting because of heavy .angler pressure. There is a fingerling program, using fish up to three inches, for planting -- usually by. air drops -- of high altitude lakes. Survival is "low," only up to about 10 per cent since many most important.
