Fisheries; Fish trade. 61 From 1950 to 1955, two additional agar- agar companies were founded: Productos Quimicos Drovecoland Elaboracion De Pro- ductos Alimenticas Basicos, From 1955 to 1960, another pair of com- mercial processing plants emerged on the scene: Productos Quimicos Navis, , and Productos Y Derivados Marines, During 1960 to 1965,the largest increase in produc- tion of agar-agar was obtained, 800 tons per year. Since 1965, six new companies have been formed for the commercial production of agar-agar. These are Sanval, Juste, Ceamsa, Movogel, Gummagar, and Roko. In 1966, eight agar-agar processing firms formed a group under the name Hispanagar, , which is now erecting a new plant in Burgos. Production capability is 1,250 tons a year. This plant initiated production at the end of 1968. The primary problem the seaweed industry now faces is obtaining enough raw material to keep the plants in operation. The total capacity of all plants is now 1,800-2,000 tons annually; actual production was 890 tons in 1965, 600 tons in 1966, and 925 tons in 1967. This means that Spanish agar-agar plants have been operating at only about 42 percent of total capacity. CARRAGEENAN--The processing of car- rageenan from Carrageen lichen is insignif- icant. Almost all of the 300 to 600 tons of raw weed have been exported. In view of the increasing consumption of products derived from lichen in Spain, as well as in interna- tional markets, two companies are now con- structing plants for commercial production of carrageenan. These plants are being con- structed in Vigo and Burgos; proposed annual production is 400 and 180 tons, respectively. It is expected that these plants will absorb all the lichen seaweeds that can be gathered. ALGINATES--The alginate industry is re- latively new. The first efforts to produce this valuable material was tried Ln 1950, when an agar-agar manufacturer began a study of the possibility of extracting alg
