Fish Numbers Rising In The River Frome
12:09pm 3rd July 2013
Good news for the River Frome - a study was carried out by Casterbridge Fisheries, showing numbers of fish rising significantly.
The study took place following last year's major conservation and river enhancement work done by the Dorset Wild Rivers Project and involved catching and surveying the fish populations.
By creating willow mattresses, the river was narrowed by 150m at the Lower Bockhamton section to the Stinsford Channel. The narrowing process not only helps to provide a natural habitat for eels to flourish, but increases the speed of water flowing; this in turn creates clean gravels, ideal for fish to reproduce and provides a home for many types of river wildlife.
The findings reflected growth in several species, including grayling, trout and eel. The fish population and habitat diversity has improved, with overall density of fish rising almost 60%.
Eels also showed a great result, making up 50% of the catch for the survey, which is good news after previous concerns that changes to the river may be a negative impact on the species.
The grayling has also risen very significantly from 4.1% to 23.8% of the catch.
