    "name": "HERAS - 0817S - Herring acoustic survey - 2017 - North Sea and west of Scotland",
    "description": "Objectives:\r\nIn setting the survey programme and specific objectives, etc the Scientist-in-Charge needs to be aware of the restrictions on working hours and the need to build in adequate rest days and rest breaks as set out in Marine Scotland\u2019s Working Time Policy (Lab Notice 34/03). In addition, the Scientist-in-Charge must formally review the risk assessments for the survey with staff on-board before work is commenced.\r\nIn the interest of efficient data management it is now mandatory to return the Survey Report, to I Gibb and the Survey Summary Report (old ROSCOP form) to M Geldart, within four weeks of a survey ending. In the case of the Survey Summary Report a nil return is required, if appropriate\r\n2\r\nTo conduct an acoustic survey to estimate the abundance and distribution of herring in the north western North Sea and north of Scotland between 58\u00ba30\u2019-62\u00baN and from the shelf edge to 2\u00baE, excluding Faroese waters. In addition acoustic transects will be carried out in Moray Firth to estimate abundance of herring and sprat.\r\nTo obtain biological samples by trawling with pelagic and demersal trawl for echosounder trace identification.\r\nTo obtain samples of herring and sprat for biological analysis, including age, length, weight, sex, maturity, ichthyophonus infection throughout the survey area.\r\nCollect samples and data for stock identity determination for herring caught west of 4 \u00baW (photos and otoliths for morphometric stock ID analysis and tissue samples for genetic analysis).\r\nTo test feasibility of using GoPro cameras mounted in the net and on a dropframe to further aid in species identification in the echogram scrutiny process.\r\nTo obtain hydrographic data for comparison with the horizontal and vertical distribution of herring and sprat.\r\nTo test different deployment scenarios for the Edgetech broadband system with the aim of minimizing noise and use the system to collect data on fish schools for ongoing collaborative work with University of Aberdeen.",
