Summary
[edit]DescriptionZebra mussels sign, Antrim - geograph.org.uk - 1625378.jpg |
English: Zebra mussels sign, Antrim. The non-native zebra mussel first appeared in Lough Neagh in 2005. The Habitas website describes them thus: "Ecological impacts are varied and unpredictable. Zebra mussels change nutrient cycles, filter out phytoplankton which forms the basis of the food chain, increase water clarity and increase plant growth around lake margins. They reduce the amount of zooplankton, an important fish food. Colonies of zebra mussels change the habitat of other invertebrates and they attach to native mussel species causing their local extinction. Changes in fish populations can also occur as zebra mussels colonise spawning grounds, change habitat and food sources."
The sign is beside the Sixmilewater close to where it enters Lough Neagh 257179. |
