The Department of Transport has issued an updated advisory for 2023 over the risk of vessels becoming entangled in ropes used in pot fishing.

Marine Notice No 31 of 2023 supersedes No 43 of 2021 and reminds all vessel owners, agents, shipmasters, skippers, fishers, yachtsmen, seafarers and those engaged in pot fishing about the risks of vessels’ propellers becoming entangled in ropes of marker buoys used to indicate the position of pots used for fishing lobster, crab or other fish or shellfish.

This can occur because the length of rope used to fix marker buoys is too long, resulting in the line floating on or just below the surface.

The use of too long a line of rope can result in a situation where even vessels that have taken a wide berth around marker buoys could have their propellers fouled by the rope.

Specifically, the department reminds those engaged in pot fishing not to use unsuitable ‘floats’ (eg empty drink cans, plastic bottles, dark-coloured floats, etc) which offer poor visibility and/or could be mistaken for floating debris.

Fishers who carry out pot fishing (whether commercially or non-commercially) are reminded of their obligations to other users of the sea.

Furthermore, non-commercial pot fishers are reminded of the regulations made by the Department of Agriculture, Food and the Marine covering such activity (SI No 31 of 2016 - Non-Commercial Pot Fishing (Lobster and Crab) Regulations 2016) which, inter alia, limits the numbers of pots permitted per boat to a maximum of six, and such pot fishing to the months of May to September.

Any mariners who spot any marker buoys/ropes (or any other object) in the water, which they deem to represent a danger to navigation, should communicate information on same to other vessels in the area and to the Irish Coast Guard or to the local competent authority so that a hazard warning can be issued if appropriate, and any required follow-up action can be taken.

An updated guide on good practice for pots and marker buoys is included in Marine Notice No 31 of 2023 attached below.

In response to the recent MCIB report on a fatal incident involving a fishing vessel in Galway Bay in November 2017, the latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) related to the safety of small vessels engaged in pot fishing.

The notice is directed at users of vessels less than 15m in length:

In addition, the DTTAS reminds users of small vessels that:

  • Suitable personal flotation devices (PFDs) and personal locator beacons (PLBs) should always be worn.
  • Somebody ashore should be aware of where the boat is intending to operate and when it is expected to return.
  • Vessels should have a suitable means of re-boarding in the event of a crew member falling overboard.

The DTTAS said it wishes to highlight the increased risks involved with single-person operation of such vessels.

Owners/skippers should carry out a risk assessment of the intended operations and take appropriate actions to reduce and/or mitigate the inherent risks that arise when nobody else is on board to render assistance or to raise the alarm.

A new study from Queen's University Belfast has revealed the extent of damage to horse mussel reefs in Strangford Lough, the Bray People reports.
The report highlighted a lack of action on the part of the NI government departments responsible for the lough, which is designated as a Special Conservation Area and a Marine Nature Reserve.
According to BBC News, previous studies in the late 1990s showed that many of the mussels were dead, and urged regulatory action to protect the remainer that did not come to pass until earlier this year, when two non-disturbance zones were declared to reduce pot fishing in the reef areas.
On top of the continued ban on mobile fishing gear, the new study recommends "total protection" in areas of the lough where fishing activity is affecting the recovery of horse mussel reefs, and notes that "signs of natural recovery might be expected within 20 years... provided there is no further disturbance".

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.
