Objectives | Objectives
1. To undertake a nationally co-ordinated demersal trawling survey of Anglerfish (Lophius piscatorius and Lophius budegassa) at Rockall Bank (ICES area VIb and Northwestern Shelf (ICES area VIa) inside the 1000m isobaths.
2. To additionally record and map distributions of Megrim (Lepidorhombus wiffiagonis), Four-Spot Megrim (Lepidorhombus boscii) Cod (Gadus morhua), Blue Skate (Dipturus cf. flossada) and Flapper Skate (Dipturus cf. intermedia).
3. To collect biological data on Anglerfish species, Cod, Megrim, Four-Spot Megrim, Blue Skate and Flapper Skate.
Procedures
One haul of 60 minutes duration will be made at each sampling station; trawling operations will occur in waters up to a maximum of 1000 m. Daily starting times will be 06:00 hours and all trawling should be complete by approximately 23:30 hours each night. The Scanmar system will be used to monitor wing spread, door spread and distance covered during each haul. A bottom contact sensor will be mounted on the footrope.
Catches will be worked up according to the protocols for Marine Scotland Anglerfish surveys which are similar in principle to Marine Scotland standing instructions. |
