There is one layer for each of the ten main types of fishing gear, trawl, longline, set line, set net, Danish seine, seine, jig, pot, dredge and hand-gathering (incl. diving), and one showing the catch of all fishing methods combined. <DIV STYLE="text-align:Left;"><DIV><DIV>The distribution of total commercial catch is estimated for all fishing events reported in statutory catch and effort returns for the period 1 October 2007 to 30 September 2013.The location of fishing events is reported by either start (or start and end) coordinates (precise to 1 nautical mile) or by large statistical areas. The total catch of all species from each and every fishing event is spread uniformly over a polygon of space estimated to be occupied by that fishing. Trawl fishing polygons are derived from the length and width of the door-spread for the duration of the tow. The path of each tow is taken as a straight line between start and end coordinates where these are reported, or between start and estimated end coordinates. Where not required to report end coordinates, (the case for most inshore trawling) tow end points are derived using the direction of the next tow start position or the direction of the landing point for the last tow of the day. This has proven to be a reasonably good predictor of trawl direction.Line fishing is attributed to a circle with centre at the reported start position and radius of the reported length of line set. Set net fishing is attributed to a circle with centre at the reported start position and radius of 2 nm in accordance with the definition of a single set netting event prescribed in reporting regulations. Jig fishing reports a single nightly position and is assumed to occur within 5 nm of that position. Hand and Pot fishing reports by statistical area, and where available, information on habitat and depth or information supplied by fishers is used to define the parts of each statistical area where each type of fishing is likely to have occurred. In the case of lobster potting and paua diving an informal map of reef area supplied by the Department of Conservation is used to estimate where this fishing may have occurred.Catch intensity (kg/ha) is mapped to a square kilometre grid for all fishing events and summed over gear types. The data is aggregated into grid squares of between 1 and 2500 km2 as required to give 6-year annual averages of data from at least three permit holders. Catch per unit area values are classified into ten intensity classes and displayed in intuitive heatmap colours.MPI has high confidence in the data on catch quantities used here but the spatial distributions of those catches are only approximate and should be used with caution especially at large map scales (maps of small spatial extent). Nevertheless, the aggregation of a large number of fishing events tends to provide consistent patterns that have passed scrutiny when tested with groups of fishers. Fishers have not been given the opportunity to “ground-truth” this series of maps at this time.</DIV></DIV></DIV> Ministry for Primary Industries (MPI) <DIV STYLE="text-align:Left;"><DIV><DIV>The colours used in these layers have been applied to show fishing catch estimates at a national scalewhich might fail to highlight locally important fisheries.All values and locations displayed within these datasets are based on the best available information at the time of creation. Where accurate location information is lacking, fishing events havebeenaggregated to broader areas such as a fishery statistical areas,or where an informed guess can be made, to a subset of a statistical area (such as rocky areas within a statistical area for paua fishing events). Attempts have been made to reduce the appearance of fishing activity occurring within closed areas but some cases may still exist. These are artifacts caused during the dataset creation and MPI isnot implyingthat fishing actually occurredwithin these closed areas.See Legal Constraints for any licences attached to this dataset.Disclaimers This map and all information accompanying it (the “Map”) is intended to be used as a guide only, in conjunction with other data sources and methods, and should only be used for reference purposes.
