Introduction: Species Notes for this Location:
Evidence of self-sustaining populations was found for carp Cyprinus carpio in the Trent and Avon (Nunn et al. 2007). Carp are currently rare in the lower Trent and Avon, with the majority captured from or near to connected floodplain waterbodies (Nunn et al. 2007). However, the continued stocking of carp into stillwaters and rehabilitation of floodplains, and the potential effects of climate change, could serve to increase the carp populations of lowland rivers (Nunn et al. 2007). Management Notes for this Location:
The Trent is the third longest river in the UK (274 km), and has a catchment area (10 500 km2) that is similar in size to those of the rivers Severn and Thames, while the Ouse is 200 km long (catchment 10 000 km2) and the Avon 180 km long (catchment 3000 km2). The Avon is a major tributary of the River Severn, which discharges into the Bristol Channel, and has a less diverse natural fish fauna than the Trent (Nunn et al. 2007). Impacts:
Other: Notwithstanding the negative impacts, some values may occur as the species is popular with specialist anglers (Nunn et al. 2007). Last Modified: 10/12/2009 3:48:33 p.m.
