The crew studied the location, relative abun- dance and distribution of commercial fish stocks, their availability to bottom trawls, and the nature of areas suitable for trawling.

Fish samples were collected for biological and pesticide studies. cordings revealed extensive and widely distributed schools from one end of U. S. part to the other. Fishing Results: Total production was 8,539 percent alewife and percent smelt--taken in only 9 hours and 50 minutes of fishing time. Other species amounted to only 7 pounds. Commercially significant catches of alewife of 700,440 and 900 pounds per drag were taken off Niagara Bar at 20, 25, and 45 fathoms, respectively. Off Rochester, 4 drags produced 630 to 1,500 pounds of alewife (average 1,158 pounds) at 15 to 30 fathoms. The best catches of smelt (40 and 30 pounds) off Rochester were taken at 15 and 20 Lake Ontario explorations, R/V Kaho Cruise 37. Highlights: (1) Large catches, almost all alewife, as large or larger than those in Lake Michigan during this time of year. (The 1966 forecast for the new Lake Michigan alewife fishery was for over 30 million pounds.) (2) Ideal bottom trawling grounds extending from 10 to 50 fathoms along most of Lake Ontario's south shore. Exceptionally good t raw ling grounds were found minutes away from Youngstown, N. Y. (Niagara Bar) and Roch- ester, N. Y.
