As part of a trout assessment project initiated in 2000, cutthroat Oncorhynchus clarkii and rainbow trout O. mykiss were sampled from the Copper River Special Management Area for Trout (CRSMT) on the Martin River Delta of southcentral Alaska in 2001-2003. The objectives of the study were to assess length at age for trout in the CRSMT, observe trout movements, and gather information on the distribution of anadromous fish species in the area. Trout sampled in streams of the Clear Martin River in the southern half of the CRSMT were larger and older than trout from the northern streams. Recaptures of tagged trout showed movements within sub-drainages, but not movements between major northern and southern drainages. Cutthroat, rainbow, and cutthroat/rainbow hybrid trout were identified in the clear Martin River, but cutthroat trout dominated the samples in the northern streams of the glacial Martin River. Dolly Varden Salvelinus malma were common in all sampled streams, but Arctic grayling, Thymallus arcticus, and whitefish, Coregonus spp., were found in only a few locations. Additionally, coho O. kisutch, sockeye O. nerka, chum O. keta and pink salmon O. gorbuscha were observed throughout the CRSMT.
