Indigenous fish - modelled migratory pathway

NOTE: Modelled distribution for all fish species have been amalgamated into one dataset. Please use the Common Name field (or the Species field) field to split them out. As a consequence of this amalgamation each river/stream reach in the dataset may be represented multiple times - one for each species it relates to. The information below relates to all four indigenous fish datasets: Indigenous Fish - Known Historic Locations Indigenous Fish - Known Migratory Pathways Indigenous Fish - Modelled Distribution Indigenous Fish - Modelled Migratory Pathways. These datasets combine information from several data sources to identify potential distributions of native freshwater fish and their migratory pathways in the Bay of Plenty Region. Please note that fish distributions are subject to change as our knowledge of species distributions grows over time. Known historic and known migratory locations are based on the combination of recorded observations from the New Zealand Freshwater Fish Database and an internal BOPRC fish dataset compiled in September 2021. ‘Modelled distributions’ for each species are based on the predicted distributions using the following model: Crow, S.K., Booker D., Sykes J., Unwin M., Shankar U. 2014. Predicting distributions of New Zealand freshwater fishes. NIWA Client Report CHC2014-145 The probability threshold applied for each species in the model is listed as follows: Common name Ecological database abbreviation Modelling probability threshold Banded kōkopu Galfas ≥0.42 Bluebill bully Gobhub ≥0.20 Common bully Gobcot ≥0.41 Common smelt Retret ≥0.37 Cran’s bully Gobbas ≥0.24 Dwarf galaxias Galdiv ≥0.315 Giant bully Gobgob ≥0.28 Giant kōkopu Galarg ≥0.74 Īnanga Galmac ≥0.26 Koaro Galbre ≥0.535 Lamprey Geoaus ≥0.51 Longfin eel Angdie ≥0.65 Redfin bully Gobhut ≥0.25 Shortfin eel Angaus ≥0.46 Shortjaw kōkopu Galpos ≥0.335 Torrentfish Chefos ≥0.6 The ‘known migratory pathway’ and ‘modelled migratory pathway’ link the known and modelled species locations to the coastal environment. This reflects the connectivity required for species to compete their lifecycles. For information on the specific habitat requirements and lifecycles of freshwater fish, please see Habitat requirements of native freshwater fish in Aotearoa New Zealand (https://www.doc.govt.nz/nature/native-animals/freshwater-fish) There are also other freshwater mahinga kai species where only a few sites are listed in the New Zealand Freshwater Fish Database, and no model for their distribution is available.

NIWA客户报告CHC2014-145 本模型为各物种设置的概率阈值如下： 通用名称 生态数据库缩写 建模概率阈值 带纹kokopu（Banded kōkopu） Galfas ≥0.42 蓝嘴䲁（Bluebill bully） Gobhub ≥0.20 普通䲁（Common bully） Gobcot ≥0.41 普通胡瓜鱼（Common smelt） Retret ≥0.37 克兰氏䲁（Cran’s bully） Gobbas ≥0.24 矮银汉鱼（Dwarf galaxias） Galdiv ≥0.315 大kokopu（Giant kōkopu） Gobgob ≥0.28 伊南加（Īnanga） Galmac ≥0.26 科罗鱼（Koaro） Galbre ≥0.535 七鳃鳗（Lamprey） Geoaus ≥0.51 长鳍鳗（Longfin eel） Angdie ≥0.65 红鳍䲁（Redfin bully） Gobhut ≥0.25 短鳍鳗（Shortfin eel） Angaus ≥0.46 短颌kokopu（Shortjaw kōkopu） Galpos ≥0.335 湍鱼（Torrentfish） Chefos ≥0.6 "已知洄游路径"与"建模洄游路径"将已知及建模得到的物种分布点与沿海环境进行关联，以此体现物种完成生命周期所需的生境连通性。如需了解本土淡水鱼类的具体栖息地需求与生命周期特征，请参阅《奥特亚罗瓦新西兰本土淡水鱼类栖息地需求》（https://www.doc.govt.nz/nature/native-animals/freshwater-fish）。 此外，还有部分淡水传统可食用物种（mahinga kai，毛利语，意为本土传统食物来源物种），仅在新西兰淡水鱼类数据库中记录了少量分布点，且暂无对应的分布建模数据，具体包括：NZFFD_Kakahi_echmen（无对应模型）、NZFFD_Koura_parpla（无对应模型）。
