Fish Relocated from East Sussex Pond After Oxygen Depletion Caused Deaths

Following a series of fish fatalities attributed to diminished oxygen concentrations in the water, a “substantial quantity” of fish have been relocated from a pond situated in East Sussex. According to Hailsham Town Council, several factors have contributed to the reduced oxygen levels in Common Pond, including summer heat, the proliferation of blue-green algae blooms, and decomposing food remnants left by individuals feeding waterfowl. The council stated that a significant number of fish from the pond have been transferred to a nearby fishery. This action is expected to increase oxygen availability in the water, thereby facilitating the recovery of the ecosystem. Phil Hobden, who serves as the town council’s pond warden, indicated that the removal of fish from what he described as “the jewel in Hailsham’s crown” was an unavoidable measure. He elaborated, stating, “The reality is, unless we remove most of the fish from the pond, we will keep repeating the cycle of increased algae levels, rapid drop in oxygen levels in the water and more dead fish and waterfowl.” He continued, “For this reason, we cannot allow such a large fish population to exist in the pond and have had to remove most of them from the pond.“ He further added, “Though by no means as extreme as the summer in 2023, the warm weather in June and lack of any significant rainfall meant that we had to act sooner rather than later to prevent any further reduction in the quality of water levels caused by climate change.” Concluding his remarks, he stated, “Keeping fish numbers low will ensure that the water quality remains satisfactory and the overall health of the pond is maintained.” The precise count of fish relocated by the council, or the number still residing in the pond, has not been disclosed.
