Exploration in the offshore waters of Southeastern Alaska be- tween Dixon Entrance and Hazy Is- lands was carried out from May 23- June 30 using standard 400-mesh Atlantic otter trawls and a 40-foot Gulf of Mexico flat shrimp trawl. Fishing efforts in this area reveal- ed a considerable amount of clear trawling bottom and significant con- centrations of Pacific ocean perch (Sebastodes alutus) and black rock- fish (Sebastodes melanops). Ex- ploration in both inshore and off shore waters of Southwestern Alas- ka from the Shumagin Islsuids to Unalaska Island was conducted from July 18-October 1. Standard king crab pots and 400-mesh Pacific ot- ter trawls were used in this area in addition to the gear used in South- eastern Alaska. King crab were taken in fair amounts in some places, and excellent catches of shrimp were made consistently in several localities. The exploration off Southeast- ern Alaska was a continuation of work initiated by the Service's ex- ploratory fishing vessel John N. Cobb in the fall of 1956. Pacific ocean perch were caught by the Tordenskjold at depths of 87-140 fathoms at average rates of 1,000- 3,150 pounds per hour in each of the following axeas: in the 125- fathom gully off Timbered islet, along the 100-fathom edge offshore from Wolf Rock to Forrester Island, and on the 125-fathom bank south of Forrester Island. Average catches of 1,100 pounds of black rockfish per hour were made near the 100-fathom edge off Noyes Island. Off Cape Bartolome several half-hour drags with the Gulf shrimp trawl at depths of 82-93 fathoms caught from 130-340 pounds of small pink shrimp. Seventy percent of the drags attempted on the Southeastern grounds came through clear. Al- though the other 30 percent "hung up," very little gear daxnage re- sulted. Weather conditions were generally good in sharp contra
