Migratory Salmonid Habitat 2003 – Map 16 Ballyshannon Fisheries District
收藏资源简介：
<span style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'>A GIS based quantification of Ireland's freshwater salmon habitat asset to determine the habitat quantity (wetted river and lake surface areas) available to migratory salmonids. The purpose was to inform the further development of salmon stock recruitment models to provide high quality scientific advice to inform the sustainable management of salmon fisheries in Ireland. </span><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><div style='font-family:inherit;'>The identification of these rivers as Salmon, Sea Trout or other types of systems is still valid and has not changed since the 2003 report was published. It should be noted that rivers identified in 2003 as ‘Not considered a significant producer of migratory Salmonids’ or river segments identified as ‘Not utilised by Salmon’ may hold small populations of salmon and/or sea trout which are important in biodiversity terms.</div><div style='font-family:inherit;'>Please note that the wetted areas (riverine habitat (m²)) were revised in 2012 (McGinnity et al., 2012). This work built on the 2003 wetted area report (Mc Ginnity et al., 2003).</div><div style='font-family:inherit;'><br /></div><div style='font-family:inherit;'><i>McGinnity, P.,Gargan, P.,Roche, W., Mills, P. & McGarrigle, M. 2003.

本数据集围绕基于地理信息系统（Geographic Information System，GIS）的爱尔兰淡水鲑鱼栖息地资产量化研究构建，旨在明确洄游性鲑科鱼类可利用的栖息地规模，即河道与湖泊的湿润水面面积。本研究的核心目标是为鲑鱼种群补充模型的迭代开发提供数据支撑，进而为爱尔兰鲑鱼渔业的可持续管理提供高质量科学决策依据。 自2003年报告发布以来，将上述河道划分为鲑鱼河道、海鳟河道或其他类型水系的分类标准仍有效且未发生变更。需要说明的是，2003年被认定为“并非洄游性鲑科鱼类重要产区”的河道，或被标记为“未被鲑鱼利用”的河道区段，仍可能存在少量鲑鱼和/或海鳟种群——从生物多样性角度来看，此类种群具有重要价值。 请注意，河道栖息地湿润面积（单位：平方米）的相关数据已于2012年完成修订（McGinnity等，2012），此项修订工作基于2003年的湿润面积报告（McGinnity等，2003）。 ### 参考文献 1.
