| Purpose | Research |
| Objectives | Ichthyoplankton survey
1) To survey Irish Sea fish egg abundance and distribution for the AIR egg abundance project (AIR3 2263). 2) To collect fish eggs for iso-electric focusing. 3) To measure and freeze samples of whiting and other fish larvae, caught by Gulf III deployment and by ring net drift, for lipid analysis. 4) To survey Irish Sea fish and Nephrops larvae, abundance and distribution. 5) To complete a 24 hour sampling cycle with both the Gulf III and the Ring Net, at an Irish coast station where a reasonable abundance of fish and Nephrops larvae were observed. 6) To compare Gulf III and Ring Net whiting larvae catch rates. 7) To study variation in the shrinkage rates of dab, whiting and sprat larvae that have been fixed in alcohol and formaldehyde solutions. 8) To investigate the abundance of euphausiids and other macro zooplankton in the Irish Sea. |
