Atlantic Herring (Clupea harengus)

The Atlantic herring forms some of the most spectacular schools of any fish species. These enormous aggregations can consist of billions of fish, and extend for literally miles in all directions. Atlantic herring occur throughout the north Atlantic ocean, from the Bay of Biscay northward to Iceland and southern Greenland. Their range extends eastward into […]

Atlantic Cod (Gadus Morhua)

The once plentiful cod is becoming worryingly scarce throughout its north Atlantic range. For decades it has been the most sought after commercial fish species of European fishing fleets, and stocks are now in serious decline. Experts in the field of fisheries biology agree that crashes in cod populations caused by over-fishing mean that the […]

Grey Gurnard (Eutrigla gurnardus)

The grey gurnard is a fish of the north east Atlantic, and is found as far south as Morocco and into the Mediterranean. It is relatively common around Ireland, and of the three species of gurnard found in our waters is the most likely to be encountered near the coast. In fact young grey gurnard […]

European Eel (Anguilla anguilla)

Atlantic Mackerel (Scomber scombrus)

The Atlantic mackerel is a common and widespread fish around Irish coasts. A favourite with anglers, it is often caught in great numbers during the summer when huge shoals move inshore to feed on vast numbers of herring fry and sand eel. Mackerel is a handsome, streamlined fish that belongs to the same family as […]

Basking Shark (Cetorhinus maximus)

The basking shark is the biggest fish found in Irish waters, and the second largest fish on earth after its Indo-Pacific cousin, the whale shark. Although it belongs to the same family as the notorious great white, and has more teeth than any other shark, the basking shark is actually a gentle giant. It’s a […]
