  • 摘要:Sampling was undertaken by trawling using the RV Naturaliste (21.6 m in length) with surveys commencing at approximately 30 minutes after sunset. The vessel was equipped with port and starboard deployed otter-board nets configured with a headrope length of 6 fathoms (ca 11 m) and 50 mm mesh (stretched) in the wings and 45 mm mesh (stretched) in the cod-ends. The nets were demersal with a 10 mm ground chain that was positioned two links in front of the ground rope. The effective opening of each net was ca 7.3 m wide by ca 1 m high.
