Brown trout and salmon are split into two maps to show fry (0+) and older fish (≥1+). Brown troutfry and brown trout ≥1+ both showed a good distribution throughout the region; however, densities weremarkedly higher in the Glashaboy River and the River Martin (Figs. 4.32 and 4.33). Salmon fry andsalmon ≥1+ also exhibited a good distribution throughout the region, with greatest densities in theShanowen River and the River Martin (Figs. 4.34 and 4.35).Eels were also well distributed, being present in all sites except for the River Lee at Inchinossig Bridgewith the highest densities being recorded in the Tyshe and Shanowen sites (Fig. 4.36). Three-spinedstickleback were recorded in most sites except for those within the Laune catchment, namely the Flesk,the Owenreagh and the Gweestin, as well as the Glashaboy (Fig. 4.37). Juvenile lamprey were alsopresent in most sites but were especially abundant in the River Martin along the muddy banks and amongtree roots (Fig. 4.38). Minnow (Fig. 4.39), flounder (Fig. 4.40) and sea trout (Fig. 4.41) were mainlyrestricted to the sites in north-west Co. Kerry, whereas stone loach were only distributed within the easternpart of the region in two of the Co. Cork sites, the Glashaboy River and the River Martin (Fig. 4.42).40
