uniquely tractable, and are therefore not likely to produce any 



substantial change in the level of utilization of the marine 



algal resource. (Authors' abstract.)

Summary assessment on the industry and market for seaweed 



products in the world and United States. 



Natl. Mar. Fish Serv. , NW Fish. Cent., unpubl. manuscr., 44 pp. 



The U.S. and Japanese seaweed product industries and markets are 



discussed using numerous tables and figures, and it is concluded 



that prospects may be better for a cultured seaweed industry in 



the United States if the food market is served. Lower prices for 



seaweed raw material for the industrial products market, plus its 



organization, size and structure might not be conducive to 



development of culture. Extensive data on the Japanese seaweed 



situation indicates culture production for some kinds of 



seaweeds. Japan is the world's largest producer and consumer of 



seaweed food products. U.S. industrial market use of marine 



colloids from seaweeds account for an estimated 1/2 or more of 



world output of algin and carrageenin, but only 2-5% cf the world 



agar output. The "industrial" market serves food, medical, 



pharmaceutical and other processors or manufacturers. Some 



seaweed is used as meal or fertilizer.

This paper documents all out-of-pocket and other costs in the 



construction of two experimental fish ponds. These ponds will be 



fertilized with waste materials to enhance fish growth. 



Engineering, construction, and environmental problems are 



discussed. Detailed descriptions of the project site as well as 



of the construction process itself are provided. The 



out-of-pocket and other costs are divided into categories
