My Explorers Seashore Guide WorkbookIn Ireland we are surrounded by so many different types of beaches ranging from sandy to shingle shores, as well as mudflats to rocky shore lines. This makes it extremely exciting exploring all of the amazing animals, seaweeds, plants and creatures that live there. This book was created to help you become a seashore explorer. The book can be used on the shore or in the classroom to help gather and document all of the stuff you discover on the shore. As part of becoming a seashore explorer we have also teamed up with the National Biodiversity Data team to help them identify and locate seashore animals and seaweeds around Ireland.
Shellfish Stocks and Fisheries Review 2019: an assessment of selected stocksThis review presents information on the status of selected shellfish stocks in Ireland. In addition, data on the fleet and landings of shellfish species (excluding Nephrops and mussels) are presented. The intention of this annual review is to present stock assessment and management advice for shellfisheries that may be subject to new management proposals or where scientific advice is required in relation to assessing the environmental impact of shellfisheries especially in areas designated under European Directives. The review reflects the recent work of the Marine Institute (MI) in the biological assessment of shellfish fisheries and their interaction with the environment. Stock status and exploitation status indicators are presented, where estimated, as a contribution to the assessment of Good Environmental Status (GES) of shellfish for Descriptor 3 (Commercial Fisheries) of the Marine Strategy Framework Directive (MSFD). Mitigation measures to protect habitats within Natura 2000 sites, which have been developed in response to Habitats Directive Article 6 assessments and in consultation with the industry, are summarised. The competent authority for the management of these sites is the National Parks and Wildlife Service (NPWS). The Department of Housing, Planning and Local Government oversees the implementation of the MSFD in Ireland. The information and advice presented here for shellfish is complementary to that presented in the MI Stock Book on demersal and pelagic fisheries. Separate treatment of shellfish is warranted as their biology and distribution, the assessment methods that can be applied to them and the system under which they are managed, all differ substantially to demersal and pelagic stocks.
National Survey of Sea Lice (Lepeophtheirus salmonis Krøyer and Caligus elongatus Nordmann) on Fish Farms in Ireland – 2019Farmed stocks of Atlantic salmon in Ireland are inspected on 14 occasions throughout the year to monitor sea lice levels as part of a national programme. Sea lice are a naturally occurring parasite found on marine fish, including salmonids. They are small ecto-parasitic copepod crustaceans and there are approximately 559 species. The objectives of the National Sea Lice Monitoring Programme are: To provide an objective measurement of infestation levels on farms. To investigate the nature of infestations. To provide management information to drive the implementation of control and management strategies. To facilitate further development and refinement of this strategy. The sea lice control and management strategy has five principal components: Separation of generations. Annual fallowing of sites. Early harvest of two-sea-winter fish. Targeted treatment regimes, including synchronous treatments. Agreed husbandry practices.
