#marinewildlife – The recent discovery by a local angler of the decaying remains of an exotic fish specimen in the River Suck at Correen Ford in the Midlands has raised further concern of the threat to our native wildlife from aquarium releases by otherwise well-meaning individuals. This latest discovery followed by that of a Yellow-bellied Slider turtle on the River Maigue, in Co. Limerick last week.

Despite the partially decomposed state of the fish, Inland Fisheries Ireland (IFI) staff, in consultation with international experts, believe the six inch-long, sharp-toothed specimen to be a Dragonfish (also known as a Violet or Dragon Goby). This fish is native to North and South America and can be purchased in Ireland for private aquariums.

As it is regarded as a warm water species, the Dragonfish is not considered to be able to survive in the wild in Ireland. However, according to Dr Joe Caffrey, Senior Research Officer with IFI, "There are many exotic species of potential concern sold in the aquarium trade in Ireland. These include non-native freshwater fishes, crayfish and aquatic plants. If these are released to the wild they could seriously threaten our native biodiversity and ecosystem function, and the continued conservation of internationally important native species in our rivers and lakes. It is imperative that the public and all stakeholders are aware of the potential damage that exotic animals or plants which are deliberately introduced to the wild can inflict upon our unique wildlife and habitats."

In recent years, human-mediated introductions of non-native species such as Asian Clam, Australian Swamp Stonecrop, South African Pondweed and Zebra Mussel into Irish waterways have resulted in detrimental impacts to native species and habitats, degraded the amenity value of areas that become infested and required costly control measures to be implemented to mitigate these impacts.

Under the European Communities Birds and Natural Habitats Regulations 2011, the unlicensed release to the wild of any animal species, which is not ordinarily resident in Ireland or a regular visitor to the country, in a wild state is an offence.

Any sightings of exotic plants or animals found in or around our waterways can be reported to IFI through the 'IFI Invasive Species' smart phone app which is available to download from the Google Play and iTunes App stores.

The app aids users to report and identify exotic species and take geo-referenced photographs that can immediately be sent to IFI scientists for review. If the sighting is of something new or particularly worrying, this will trigger an immediate on-site survey by IFI staff. IFI want as many people as possible to use this app and help it in its ongoing battle against aquatic invasive species.

#MarineWildlife - BBC News reports that Northern Ireland's Exploris aquarium will remain open for another two months as Ards Borough Council prepares to submit its business plan to save the facility in April.

As previously reported on Afloat.ie, the popular but loss-making tourist attraction was earmarked for closure last year - threatening the future of its more than 3,000 marine animals - but saved at the 11th hour, provided the council receives a one-off capital grant of more than €1 million from Stormont.

It's hoped that this funding would be confirmed and the aquarium will get the green light to remain operational when the NI Executive makes its decision on the plan.

That would mean Exploris could stay open for the peak spring/summer period, and close in October for a necessary six-month refurbishment over winter and next spring.

#MarineWildlife - Northern Ireland's Exploris aquarium will be saved - provided the local council receives a one-off capital grant from Stormont.

BBC News reports that a new business plan to preserve the Portaferry aquarium, which is one of the North's biggest tourist attractions, has been agreed.

But the plan's success is subject to funding of £900,000 (€1.09 million) from the NI Executive as part of a financial rescue package for the facility.

Ards Borough Council, which has run the Co Antrim aquarium since its opening in 1987, says it can no longer afford its annual operating costs of some £500,000 (€600,000).

And its closure could see more than 3,000 marine animals presently housed in the facility destroyed.

Should the new funding be confirmed, Ards Borough Council would keep Exploris open for this year's peak spring/summer period before closing for a six-month refurbishment in the autumn.

The business plan for Exploris would also preserve the aquarium's seal sanctuary, although its own future was confirmed by Environment Minister Mark Durkan in November.

#COASTAL NOTES - Northern Ireland's only aquarium could be privatised, according to the News Letter.

Ards Borough Council is reportedly considering its options for the future of Exploris, the aquarium and seal sanctuary in Portaferry that celebrates its 25th anniversary this year.

Plans were made four years ago to transfer ownership to English aquarium group Blue Reef Leisure, but the deal fell through when that firm was aquired by Spain's Aspro.

Now the council has announced it is calling for proposals for private investment in the Exploris facility - which costs around £500,000 (€600,000) a year to run - following "renewed interest from the public sector".

The move aims to "establish a clear direction for the future of Exploris", which houses one of Northern Ireland's top 10 visitor attractions in its popular seal sanctuary.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
