This project is providing important information about the wild production of Chinook salmon in the Salmon River.

Other projects conducted around the Basin by agencies, universites and other partners are documenting wild reproduction of salmon and trout, and providing managers with other scientific knowledge needed to effectively manage this highly-valued diverse fishery.

 

Natural Reproduction of Chinook Salmon in the Salmon River, NY


Research Activities and Results of 2004

To determine the distribution and abundance of salmon juveniles along the Salmon River, weekly sampling was conducted using a bag seine at 9 sampling stations systematically located along the Salmon River. Within each of the 9 stations, 4 sample units were randomly selected based on visual assessment of habitat type (pool, backwater, run, and riffle). At each of the 4 sampling units the seine was hauled over an area parallel to the riverbank.

All captured fish were identified and counted. Total length (mm) and mass (g) were recorded for the first 30 fish of each species. All fish were returned to their original habitats after processing.

Juvenile abundance in 2004 was realtively high compared to an index seining program began in 1997 by Johnson and Bishop. A total of 14,153 Chinook salmon juveniles were processed during the sampling season in 2004 (Figure 12). Large numbers of juveniles were captured early in the survey primarily in the upstream and midstream sections of the river suggesting that most of the successful hatching occurs between Ellis Cove-Salmon Wilderness (upstream-midstream) as well as between Paper Hole-Staircase (midstream). The largest capture in one seining effort was nearly 1100 fish in an area approximately 5 x 15 meters long .

There was a major flow event at the beginning of the third week of sampling causing some reductions in numbers of juveniles captured,however the most drastic overall reduction occurred after the fourth week of sampling. Most of the Chinook salmon left the river by the end of June.
