Problems concerning economies of scale and location of hatcheries 

 in the Sakhalins are discussed. The size of the hatchery is 

 limited by the availability of spawners and the water supply. An 

 example is given involving the construction of 13 small 

 hatcheries with a total capacity of 111 million eggs. To put 

 most of the hatcheries into operation, roads, river crossings, 

 and settlements with the necessities of life nad to be 

 constructed at a cost of about 20 million rubles.

This report considers systems design and operation, production 



processes, and costs for a model commercial salmon culturing 



operation with the capacity to produce about 1 million smolts at 



a cost of about 10 cents each, or $0.97 to $1.07 per pound. Two 



culture systems are involved, one for egg hatching and the growth 



of fingerlings, and the other for growth of fingerlings to 



smolts. The production cycle lasts 270 days. Costs, input 



usage and factor prices are carefully detailed and itemized in 



tables to allow updating and application to other circumstances.

Salmon mariculture potential assessed. 



Amer. Fish Farmer World Aguacult. News 2(1): 12-15, and 27. 



The authors discuss environment and facilities of the NMFS 



Aguacultural Experiment Station, Manchester, Hash., experimental 



stocks, feeding schedules, growth measurement, diseases and 



predators, and possible problems. Puget Sound tidal currents 



provide an almost continuous flow of water through floating 



enclosures, allowing a loading density of 1 pound of fish per 



cubic foot of water. One year of encouraging experimental work 



with this system and the years of work in developing a successful 



freshwater salmon hatchery system "provide the basis for an 



optimistic cutlook for the future development of intensive, 



egg-to-market culture of Pacific salmon." Technical problems 



are indicated and judged solvable. The institutional problem of 



a prospective salmon farmer's acquiring land and water use rights 



is viewed as a possible barrier, unless zoning authorities accept
