PurposeResearch
ObjectivesJuvenile gadoid study
1. To investigate the abundance and geographic distribution of juvenile gadoids in the western Irish Sea, as part of the juvenile gadoids index (1994 to 1998).
2. To collect otoliths for new recruitment project to investigate whiting growth and hatch day distributions.
3. To collect samples for biochemical investigations of larval and juvenile fish condition.
4. To investigate the spatial and temporal changes in ctenophore and chaetognath abundance.
5. To investigate the degree of MIK sample variability at fixed sites, complementing previous ring net and Gulf VII studies.
6. To obtain phytoplankton samples and physical data from the DANI mooring in the centre of the western Irish Sea.
