5203 |a"Juvenile salmonid densities, size and habitats were investigated at 90 sites in the Cowichan River system during the late summer and early winter of 1986. The sites, averaging 32 m in length, were distributed among lage, tributary, side channel, mainstem and marsh areas. Some of the sites were in areas inaccessible to anadromous fish, but where coho fry had been previously outplanted. The largest coho were taken from the lakes sites. Mainstem sites had the next largest fry followed by tributary and then side channel fry. Side channel habitat contained the highest areal densities of coho fry, followed by tributary, mainstem and then outplant areas. Except in the Somenos system, there was a general reduction in coho densities in all areas and habitat types from late summer to early winter. Coho densities were highest in pool habitat during late summer and in slough habitat during early winter. During high-water flows in the fall, there appeared to be movement of coho fry into the Somenos system. Coho fry were not caught in many of the Somenos sites in late summer and in slough habitat during early winter. Wood debris was found to be the most important cover type for both trout add coho juveniles"--Abstract, page v.
