Explorers Cephalopod Science Investigations: Squid For BeginnersExplorers Cephalopod Science Investigations: SQUID FOR BEGINNERS provides an introduction to squid for children and teachers to use in the classroom and aims to inspire a new generation of explorers. The book introduces children to science classification and the names given to squid; cephalopod evolution; and where squid are distributed and their different habitats. The book also has a section about a squids anatomy and supports the Explorers Learning about Squid Film Cephalopod Science Investigations: Squid Dissection & Fun Facts, where the special features of squid are discussed. A chapter is also dedicated to the Kraken and highlights how the giant squid has been introduced into many cultures, over hundreds of years as a giant sea monster. The book also shows our connections with squid from yummy ‘squidulicious’ food, fishing, climate change to squid in museums and sculptures. Finally, the book also highlights how squid features are influencing science, technology and engineering.
Explorers Cephalopod Science Investigations: Our Favourite Squid SpeciesExplorers Cephalopod Science Investigations OUR FAVOURITE SQUID SPECIES provides an introduction to squid species. Learning about animals such as squid, help us discover some of the amazing things about marine biodiversity and adaptation; as well as exploring the ocean around the world. This book looks at ten squid species found around the world including the largest squid in the world called the giant squid to the smallest pygmy squid, which is the size of your finger nail. Each squid information sheet identifies the English, Irish and scientific name of the squid species; its size, colour and life span. The squid sheets also highlights the ocean that the squid lives in, its habitat; what it looks like; how the squid protects itself; what it eats; and its predators.
National Survey of Sea Lice (Lepeophtheirus salmonis Krøyer and Caligus elongatus Nordmann) on Fish Farms in Ireland – 2020Farmed 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.
Environmental Survey of Coastal Waters (Galway - Dublin – Galway): – Winter nutrients, benthic macro-invertebrate and contaminants monitoring 2021 (CV21-001).The 2021 survey continues the Marine Institute’s Winter Nutrients monitoring that commenced in 1990/91. The survey has evolved and expanded during this time period with respect to target areas, parameters and sampling strategy. In 2011 this survey was reestablished as a winter environmental survey with a broader remit to provide supporting information for OSPAR and Water Framework Directive (WFD- Directive 2000/60/EC) assessments and also to maintain the winter time series on key biogeochemical parameters in Irish waters in response to pressures such as land based inputs of nutrients and climate change. Since 2011 the survey circumnavigates the Island of Ireland every two years, alternating southabout and northabout, starting in the Irish Sea and ending in Galway. This provides a complete coverage of Irelands coastal waters over 2 year periods. However, given the timing of the surveys, winter by necessity to ensure minimal biological activity and therefore highest concentrations of dissolved nutrients, the weather is a significant factor in determining the actual as opposed to planned coverage of the target stations. This work is complementary to inshore water quality monitoring activities of the Irish Environmental Protection Agency and Marine Institute and the annual offshore oceanographic survey/climate section (53N/Rockall Trough) on the RV Celtic Explorer led by the Oceans Climate and Information Services group at the Marine Institute. The 2021 survey was designed to collect multidisciplinary information on physical conditions, water chemistry (dissolved nutrients, total alkalinity (TA), dissolved inorganic carbon (DIC) and salinity), sediment chemistry (persistent organic pollutants POPs and trace metals), sediment particle size distribution and benthic macroinvertebrates (at targeted waterbodies around the coast). This contributes to data collection needs of various statutory drivers (WFD and the Marine Strategy Framework Directive (MSFD) Directive 2008/56/EC) as well as providing a research dataset on status and changing conditions (trends and variations) for key environmental variables. As a result of the COVID pandemic, operational adjustments were implemented such that scientific complement on-board was limited to 2-3 persons at any one time. In light of this, the survey plan was adjusted to allow the survey to be completed in two legs. 1. Leg 1 – Galway – Dublin: benthic macro-invertebrate sampling 2. Leg 2 – Dublin – Galway: winter nutrient, carbon and contaminants sampling. In order to achieve this plan, the number of survey days was increased to 16.
