Two days of test fishing en- couraged fishermen to engage in a commer- cial trawl fishery during the period open to the gill net fishery. The trawlers landed nearly three times as many fish per day as the av- erage of a sample of gill netters. The trawl- caught fish were in excellent condition.

Between 2,500 and 3,000 scientists and technicians are employed in oceanography and related fields of marine science in the United States, and the number is growing.

The Federal Government employs a substantial number of oceanographers. Many oceanographic positions are in activit
