Salmon populations in Dorset suffered on the worst years on record in twenty twelve. That's according to a new report which measured salmon movement in the River Frome. It found that many young salmon were killed off by last year's droughts and flooding.
Scientists say prolonged drought following by flooding could be responsible for a big drop in the salmon population of a Dorset river. The number of young salmon in the River Frome fell by more than half in just one year.
The figures come from the Game and Wildlife Conservation Trust, which has been monitoring Atlantic salmon numbers in the river for the past 40 years.
The only full-time salmon fisherman on the River Severn says new regulations risk putting him out of business and destroying a traditional way of life which dates back centuries.
The Environment Agency, which licences river fishing, has told Nigel Mott he can catch no more than 30 fish a year. Nigel Mott fishes for wild salmon near Lydney using putchers, wire cages which the salmon swim into as the tide ebbs. Previously he was allowed to caatch as many as he liked.
