| Objectives | Ichthyoplankton survey of the Irish Sea
1. To sample the ichthyoplankton of the western Irish Sea, to determine species distributions and abundance's. 2. To collect samples for primary increment analysis of gadoids to investigate larval growth. 3. To test the new Pronet system and Lebus winch for real time monitoring of the high speed plankton sampler, and to test modifications to the MIK net. 4. To sample the zooplankton in areas of high fish larval density and collect data on the abundance of other important orgainsms in the western Irish Sea, such as euphausiids, arrow worms and Nephrops larvae. 5. To collect samples, with the PUP net for analysis of nauphlii densities for the DANI/QUB MSc studentship. |
