Migratory Salmonid Habitat 2003 – Map 14 Ballina 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.

本数据集基于地理信息系统（Geographic Information System，GIS）对爱尔兰淡水鲑鱼栖息地资产开展量化研究，旨在明确洄游性鲑科鱼类可利用的栖息地规模，即湿润河道与湖泊表面积。本研究的核心目标是为鲑鱼种群补充模型的进一步开发提供科学支撑，从而产出高质量的科学建议，为爱尔兰鲑鱼渔业的可持续管理提供决策依据。 自2003年报告发布以来，上述被划分为鲑鱼、海鳟或其他水系类型的河流分类标准依然有效，未发生任何变更。需特别说明的是，2003年报告中被标记为“未被视为重要洄游鲑科鱼类产区”的河流，以及被标注为“未被鲑鱼利用”的河道段，仍可能存在少量鲑鱼和/或海鳟种群——这类种群在生物多样性保护层面具有重要价值。 请注意，2012年对湿润水域面积，即河道栖息地面积，单位：平方米，进行了修订（McGinnity等人，2012），该修订工作以2003年的湿润水域面积报告（McGinnity等人，2003）为基础展开。 McGinnity, P., Gargan, P., Roche, W., Mills, P. & McGarrigle, M. 2003. 基于地理信息系统平台解析数据的爱尔兰淡水鲑鱼栖息地资产量化研究. 爱尔兰淡水渔业、生态与管理系列丛书：第3号，中央渔业委员会，都柏林，爱尔兰。 McGinnity, P. 等人，2012. 基于地理信息系统衍生集水区与河道变量的河道栖息地面积预测模型. 渔业管理与生态学，19卷，69-77页。
