North Atlantic Herring Research LARGE SCHOOLS OF HERRING OBSERVED OFF MAINE IN JUNE-JULY BY GILL"~(Cruise 3): Large schools of herring were observed off- shore from approximately 2 miles off Petit Manan Island to approxi- mately 2 miles off Stelle Harbor Island, Maine, by the Service's research vessel TheodoreN. Gill on a 12-day cruise completed at Boothbay Harbor on July 9. A sample of these fish taken with a seine at a point 4 miles southwest off Great Wass Island, Pleasant Bay, averaged inches stand- ard length. This was the third cruise of the Theodore N. Gill in the pro- gram of exploratory fishing and biological investigation on the Maine herring fishery. The cruise was interrupted on July 2 for the Fourth-of-July weekend. Large solid concentrations of herring were located and sampled one mile east of Isle au Haut and in Hussey Sound, Casco Bay. These catches measured inches and inches, respectively, in standard length. Most of the inside waters of the Gulf of Maine from Cape Elizabeth to Machias Bay were sounded with a recording fathometer and a scanning-type echo-ranging de- vice.
