Metadata: Cod end configurations in the Farne Deeps 2017/18 - Fisheries Science Partnership
Abstract:
This work was carried out as part of the Fisheries Science Partnership (FSP) programme. The twin rig trawler Nimrod was chartered to undertake trials in a Nephrops (Nephrops norvegicus) fishery. Eleven days of fishing trials were conducted in the Farne Deeps (FU6: IVb; 38E8,38E9,39E9,40E8 and 40E9) fishing grounds off the North-East coast of England in November and December 2017. This enabled catch comparisons of five cod ends of varying mesh size, twine thickness and ircumference to be examined. The primary objective of this work was to compare the catch rates of these cod ends as those conforming to the latest licence conditions were suggested to be counterproductive by the industry. These measures were introduced in April 2016 following concerns of historical overexploitation of Nephrops in the Farne Deeps. The specific object of the project was to develop an optimum cod end construction to reduce catches of small Nephrops. A total of 27 hauls were completed for eleven days fishing, with 26 of these considered valid for examination.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The introduction of new licence conditions2 in the fishery in April 2016, brought in two changes in net construction for single rig vessels, firstly an increase in cod end mesh size from 4mm/80mm to 5mm/90mm and secondly a reduction in cod end circumference, from 120 meshes to 100 meshes. Vessel operators introduced a further change by opting for a compact braided twine used in the construction of the new cod ends. This was to prevent shrinkage of mesh size and ensure compliance with the measures. After several months many skippers felt that these new cod ends were detrimental and in fact counterproductive, stating that more, smaller Nephrops and fin fish were being caught. |
