This record is an overview entry for biological data collected on Soela cruise SO 3/80. This cruise took place in the Great Australian Bight during 26 April - 18 May 1980, under the leadership of John Stevens. Biological data collected on this cruise include EK 50 acoustic data of pelagic fish abundance. Phytoplankton filtered samples for later chlorophyll-a extraction. Fish eggs and larvae from the plankton samples. Numerous larval and juvenile cephalopods. Pilchard (27 kg) samples, the otoliths, scales and stomach contents of pilchards were retained. In the diel feeding study, Pterygotrigla polyommata occurred in every shot and preliminary results showed that 87% of this species caught in the post dawn trawl had food in their stomachs compared with 25-30% at other times.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.
