Through awareness of information collected on Marine Biodiversity this project will enable engagement with stakeholders with an interest in Ireland’s marine resource.
As part of the data collection framework, the Marine Institute conducts ten annual fisheries research surveys at sea to provide fisheries independent data for stock assessment.
Data is a key input into the advice which drives fisheries management but access to it is often restricted to scientists. This project provides tools for a number of different audiences to discover and explore the fisheries data that is collected within Ireland.
Crayfish stocks are heavily depleted in Irish waters. This depletion has been driven by over exploitation since the introduction of tangle netting in the 1970s. The restoration potential relies on acquiring better data on crayfish essential habitat, information on migration and stock structure and in managing fishing interactions.
Skates are a branch of the shark family, we sometimes called them flat-sharks. Some of these flat-sharks or skates are extremely rare with Ireland holding some of their last remaining European populations. The main refuges for these species are Tralee and Galway Bay.
Many of the stocks which are caught by the Irish commercial fishing fleets are considered to be data-limited or are not assessed at all. These include a number of key stone species (like sprat, gurnards, saithe, pollack, ling) and species sensitive to the impacts of fishing (like rays and skates, john dory, brill and turbot).
This project is designed to measure the effectiveness of management or mitigation measures taken as part of aquaculture licencing decisions to reduce or minimise risk to conservation features. Such measures are likely to be of the form of, 1) licence conditions that place certain constraints on activities in certain areas or, 2) redrawing site boundaries.
A number of short studies are required to complement the aquaculture advice provided by the Marine Institute to the Department of Agriculture, Food and the Marine in relation to licencing decisions and mitigation measures.
Several studies have indicated large accumulations of plastic microfibers in the gut of Dublin Bay prawns Nephrops norvegicus and in the sediments in which they live. The complicated gut system in this species is suggested to retain plastic fibers and places these stocks at potentially high risk of interference from marine microplastic pollution. Fibers which are too large or numerous to pass through the gut can form balls of aggregated material over time.
