Shellfisheries and Aquaculture

Can shellfish be collected by the public and are they safe to eat?
Anyone who wants to collect shellfish for personal consumption should be aware of the health risks involved. They should also be aware of the European Food Hygiene Regulations (EC Regulation 853/2004). Anyone who wishes to gather shellfish by hand for commercial reasons should contact the Department of Agriculture, Fisheries and Food in Ireland, the Department of Agriculture and Rural Development in Northern Ireland or the Loughs Agency for advice.

Do Lough Foyle oysters have a disease? Is it harmful to humans?
A tiny percentage of native oysters in Lough Foyle have tested positive for a microscopic parasite called Bonamia ostreae. This parasite can cause mortality in native oysters, especially during spawning seasons and when the water temperature is high.  However, this parasite is not harmful to humans.

What are red tides/harmful algal blooms?
Shellfish are filter feeders. They eat by siphoning water through their gills and collecting any suspended food particles in the seawater. Their diet contains plant and animal material in the form of plankton which can be toxic to humans if eaten. For this reason, it is important to monitor levels of harmful plankton.

This toxic plankton is known as red tides or harmful algal blooms. Government scientists carry out weekly monitoring to determine whether toxic species are present in the water. If harmful plankton is found, shellfish are not harvested or sold for human consumption.

Such incidents are not uncommon elsewhere in Ireland and the UK but they’re very rare in Lough Foyle and Carlingford Lough. Nevertheless, to be on the safe side, it’s best to check with the monitoring body before eating shellfish from Lough Foyle or Carlingford Lough.

What shellfish are there in Lough Foyle and Carlingford Lough?
Lough Foyle is home to many species of wild shellfish. Blue mussels and native oysters are the most abundant types. Brown crabs, velvet crabs, spider crabs, green crabs, lobsters, prawns, winkles, clams and whelks can also be found there. There is a traditional fishery for native oysters in Lough Foyle that has been fished by local people for centuries.

Lough Foyle also supports a thriving shellfish aquaculture industry, which produces about half of Ireland’s total annual production of blue mussels. Pacific oysters are also farmed in Lough Foyle and sold in restaurants throughout Europe.

Carlingford Lough is also home to large populations of blue mussels. These are found in wild mussel beds and are farmed in aquaculture sites within the Lough. Green crabs, brown crabs, lobsters, clams, prawns, winkles and native oysters are also present in the Lough. Pacific oysters, Manila clams, native oysters and mussels are all farmed in Carlingford Lough – both on the seashore and on the seabed.
