Abstract:
Fish (all species) catches from bottom trawls, for details see Johannesen et al (2021). The input data is from the Barents Sea NOR-RUS ecosystem cruise in autumn (survey report ref), Norwegian vessels only. Please consider pooling eelpouts and liparids to the family level and removing observervations listed in Appendix 2 in Johannesen et al (2021). Also consider removing the following observations: (Cruice number/Serial number) 2020209/2385: "Paraliparis bathybius" (outside known depth distribution), 2020111/2527: "Anisarchus medius" (outside known distribution area), 2020111/2571: "Anisarchus medius" (outside known distribution area), 2020111/2591: "Anarhichas denticulatus" (likely misidentified), 2020111/2597: "Anarhichas denticulatus" (likely misidentified), 2020111/2603: "Anarhichas denticulatus" (likely misidentified), 2020111/2606: "Anarhichas denticulatus" (likely misidentified), 2020111/2606: "Enchelyopus cimbrius" (outside known distribution area), 2020111/2610: "Anarhichas denticulatus" (likely misidentified), 2020111/2617: "Anarhichas denticulatus" (likely misidentified), 2020111/2621: "Anarhichas denticulatus" (likely misidentified), 2020111/2630: "Anarhichas denticulatus" (likely misidentified), 2020111/2631: "Anarhichas denticulatus" (likely misidentified), 2020111/2643: "Anarhichas denticulatus" (likely misidentified). The output data are in the two tables (output/report/ReportSpeciesCategoryCatch_Weight/ReportSpeciesCategoryCatchData.txt and output/report/ReportSpeciesCategoryCatch_Count/ReportSpeciesCategoryCatchData.txt) with one row per haul, information about the hauls in the first 26 columns, and weight (kg) and number of fish, respectively, of each haul for the different species in the subsequent columns. Species names are translated from the catchcategory field of the NMDBiotic_3.1 format (usually corresponding to taxonomic serial number (TSN/ITIS)) to values stored in the translation file "Barents Sea Fish Reference List.csv" located in the input folder. The column named NA refer to missing species information. The column V1 refer to species present in the translation file but with empty NewValue. Columns named by numeric TSN/ITIS codes are present in the data but not in the translation list.
