IWJS were called in last week to assist the EA clear dead fish from a small area of the Norfolk Broads. The current pleasant weather has had the unfortunate side-effect of increasing a buildup of toxic algae which depletes oxygen levels in the water and kills fish.
The algae bloom has been attributed to a mixture of environmental conditions, including salinity and water temperature. It is not known what has caused these conditions to alter so dramatically.
The EA rescued and relocated 230,000 fish last month after they were found shoaling in a shallow haven away from the bloom near Potter Heigham.
A further 110,000 have recently been moved from Somerton, roughly six miles away, and over the weekend another 300,000 fish were moved.
