Survey:<\/strong> 0218H – MFV Genesis BF505<\/p>\n

Duration<\/strong>: 6-20 April 2018<\/p>\n

Fishing Gear:<\/strong> Anglerfish Trawl BT 195<\/p>\n

Objectives<\/strong><\/p>\n

    \n
  1. To undertake a nationally coordinated demersal trawling survey of Anglerfish (Lophius piscatorius <\/em>and Lophius budegassa)<\/em> in the Northern North Sea, ICES area IVa.<\/li>\n
  2. To record and map distributions of Megrim (Lepidorhombus wiffiagonis)<\/em>, <\/i>Four-Spot Megrim (Lepidorhombus boscii<\/em>)<\/i> Cod (Gadus morhua<\/em>), <\/i>Blue Skate (Dipturus cf. flossada<\/em>) <\/i>and Flapper Skate (Dipturus cf. intermedia<\/em>).<\/i><\/li>\n
  3. To collect biological data on Anglerfish species, Cod, Megrim, Four-Spot Megrim, Blue Skate and Flapper Skate.<\/li>\n<\/ol>\n

    Procedures<\/strong><\/p>\n

    This trawl survey follows a set of protocols drawn up by an industry science survey planning group<\/a> made up of Marine Scotland scientists and fishing representatives. These protocols share much in common with the sampling regimes described in Marine Scotland standing instructions for demersal trawl surveys.<\/p>\n

    Trawling<\/strong><\/p>\n

    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.<\/p>\n

    Catches will be worked up according to the protocols for Marine Scotland Anglerfish surveys which are similar in principle to Marine Scotland standing instructions.<\/p>\n
