Description: During the periods 25 June through 16 July and 22 through 28 August, 1998 an angler survey was conducted between mile 20 and mile 55 of the Holitna River. During the June and July period 51 interviews were conducted and most anglers were targeting chinook salmon Oncorhynchus tshawytscha. Weekly estimates of CPUE for chinook salmon averaged 0.45 fish per hour. Participation was highest during the first week of the survey with a maximum daily count of 13 anglers and 5 boats. Fishing for chinook salmon was concentrated near the mouth of the Hoholitna River. In the August period 50 anglers were interviewed: the primary species targeted was coho salmon. Average CPUE for coho O. kisutch in August was 1.3 fish per hour. The maximum daily count during the August period was 13 anglers and five boats. The coho fishery was not concentrated like the fishery for chinook and was distributed throughout the survey area. Most of the anglers interviewed were guided (72%) and were not residents of Alaska (91%). No local anglers were interviewed in the survey area. Most anglers remained in the survey area for approximately one week. In addition to salmon, a small proportion of anglers targeted northern pike Esox lucius (19%) and sheefish Stenodus leucichthys (5%). Eighteen of 20 chinook salmon sampled were males with 65% age 1.3 and 30% age 1.4. Most coho salmon were age 2.1 (84%) and 73 of 114 sampled were males. Northern pike were generally not retained in the sport fishery. Northern pike sampled in test fishing efforts ranged in length up to 1,093 mm FL and in age to age-19. Few sheefish were obtained; 25 sheefish ranged in length between 525 and 805 mm FL and in age groups age-5 through age-8. Arctic grayling Thymallus arcticus and Dolly Varden Salvelinus malma were not targeted by anglers in the survey area.
