PurposeResearch
Objectives1. To collect samples of herring in spawning conditions at Ballantrae Bank in order to establish the meristic and age structure of the spawning stock and to obtain eggs for measurement purposes.
2. To obtain samples of ripe herring for egg fertilisation to provide material for oil pollution and other experiments.
3. To use the ROV "Sea-pup" to search Ballantrae Bank and other areas for presence of herring spawn.
4. To lay a current meter on the site of the herring egg patch discovered in 1988.
5. To enable the diving team to undertake a pre-spawning investigation of the gravel beds, and to set up some experiments on the gravel beds prior to spawning.
6. To undertake limited hydrographic work on Ballantrae Bank to establish temperature and salinity profiles during the period of the cruise.
7. To set up a time-lapse camera or a frame with a pan and tilt camera if herring shoals are observed on the echo sounder in an attempt to obtain film if spawning herring.
8. To use a "Day" grab to sample any areas of spawn that are observed during the cruise.
