| Acc. Number | 2018-X:19 | Specimen Remarks | m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month. | ||||
| Collecting Event Remarks | Water Temp. = 21C. Most of the fish were seined in <25 cm of water. Upstream of this point G. aculeatus became increasingly rare until they became absent at point indicated on map. Conversely within the same stretch of stream, Oncorhynchus sp. become increasingly abundant. Upstream of this point the river becomes increasingly dominated by alternating riffles and pools with occassional water falls of about 3 a meter. However these falls are probably not used at during high water. | ||||||
