Author: Simon Steel
Document Type: Monograph
During August and September 1996 an Electric Fishing Survey was carried out on the River Taw catchment in which 104 sites were monitored. The routine fisheries surveys undertaken by the Devon Area Fisheries Science Team provide an indication of the general health of the fishery and highlights areas of juvenile production. The 1996 Taw Fisheries Survey concluded that salmonid spawning in the autumn and winter of 1995 was successful and the distribution and abundance of both 0+ trout and salmon was generally higher than that recorded in 1993. The distribution of all age groups of trout remains widespread throughout the catchment, with the abundance of 0+ year class being generally higher than recorded in 1993. Improvements to Clevemill Weir on the Taw have allowed salmon to access spawning gravels in the river's headwaters on Dartmoor. Despite initial concern, the Denil fish pass at Head Weir on the Mole is allowing migratory fish to access to the Mole and Bray There is little evidence to suggest that transfer of water from the Exe to the Taw has had either an adverse or beneficial impact on the Molland Yeo or the catchment as a whole.
