Collecting Event Remarks |
Water Temp. = 21 C. This is a stretch of habitat appropriate for G. aculeatus about 100 m long. Elsewhere in this area the gradient is rather steep. A few hundred in downstream a fall at a gauging station probably prevents upstream migration. Males [Gasterosteus aculeatus] with nuptial coloration, gravid females. Also caught Cyprinidae sp., Oncorhynchus mykiss, and Lepomis sp. |
