Oyster restrictions and prohibitions

Commercial Fishing Regulations in this dataset include, but are not limited to: Fisheries (Auckland and Kermadecs Commercial Fishing) Regulations 1986, Fisheries (Challenger Area Commercial Fishing) Regulations 1986, Fisheries (Central Area Commercial Fishing) Regulations 1986, Fisheries (South-East Area Commercial Fishing) Regulations 1986, Fisheries (Southland and Sub-Antarctic Areas Commercial Fishing) Regulations 1986and Fisheries (Commercial Fishing) Regulations 2001. Current and historical copies of these regulations can be found online at: www.legislation.govt.nz Also included in this layer are Fisheries (Benthic Protection Areas) Regulations 2007, Fishery Notices (including beach cast seaweed and temporary closures), Marine Reserves, Marine Mammal Protection Notices, Submarine Cables and Pipelines Protections and other restrictions. Method of creation: The geometries of the features were sourced from the area descriptions provided within legislation or from another agency. The polygons were created by various methods, such as, but not limited to: using gazetted coordinates, snapping polygon vertices to LINZ Topo50 Coastline, relating to Aerial Imagery, appending polygons from other datasets such as the LINZ New Zealand Exclusive Economic Zone layer. Please note: Many features in this dataset contain general inland boundaries that are not part of the defined area. Features with a value of 1 in the ‘CoastlineRemoval’ field contain general inland boundaries. This is for the purposes of reducing vertices (to improve performance) and to future proof the data from changes to the coastline (users can erase the latest coastline data from the layer). For analysis, it is advised to erase the coastline area from features with general inland boundaries, such as the LINZ Topo 1:50k Coastline layer. The following fields within the attribute table may include helpful information related to how the geometries were created: MappingNote, CoastlineRemoval, SpecialConditions, AreaDescriptionURL and Keywords.本数据集收录的商业捕鱼法规包括但不限于：1986年《渔业（奥克兰及克马德克群岛商业捕鱼）条例》（Fisheries (Auckland and Kermadecs Commercial Fishing) Regulations 1986）、1986年《渔业（挑战者海域商业捕鱼）条例》（Fisheries (Challenger Area Commercial Fishing) Regulations 1986）、1986年《渔业（中部海域商业捕鱼）条例》（Fisheries (Central Area Commercial Fishing) Regulations 1986）、1986年《渔业（东南部海域商业捕鱼）条例》（Fisheries (South-East Area Commercial Fishing) Regulations 1986）、1986年《渔业（南地及亚南极海域商业捕鱼）条例》（Fisheries (Southland and Sub-Antarctic Areas Commercial Fishing) Regulations 1986）以及2001年《渔业（商业捕鱼）条例》（Fisheries (Commercial Fishing) Regulations 2001）。上述法规的现行与历史版本均可通过新西兰立法官网www.legislation.govt.nz在线获取。 本数据集图层还涵盖2007年《渔业（底栖保护区）条例》（Fisheries (Benthic Protection Areas) Regulations 2007）、渔业通告（含海滩漂流海藻管控及临时禁捕区域）、海洋保护区、海洋哺乳动物保护通告、海底电缆与管道保护措施及其他相关限制规定。 要素创建方式：要素的几何信息来源于法规载明的区域描述或其他第三方机构提供的数据源。多边形要素的生成方式多样，包括但不限于：采用官方公布的坐标、将多边形顶点匹配至新西兰土地信息局（Land Information New Zealand，简称LINZ）Topo50海岸线图层、结合航空影像进行绘制、从其他数据集（如LINZ新西兰专属经济区图层）追加多边形要素。 请注意：本数据集内多数要素包含不属于划定范围的通用内陆边界。当要素的CoastlineRemoval字段值为1时，即代表其包含此类通用内陆边界。此举旨在减少顶点数量以提升运行性能，并使数据可适配未来海岸线变化——用户可自行从图层中擦除最新的海岸线数据。如需开展空间分析，建议从包含通用内陆边界的要素中擦除海岸线区域，例如使用LINZ Topo 1:50k海岸线图层。 属性表中的以下字段可为要素几何信息的创建方式提供辅助参考：MappingNote、CoastlineRemoval、SpecialConditions、AreaDescriptionURL及Keywords。
