摘要: The REFISH (Restoring Endangered Fish In Stressed Habitats) Project was established in 1988 to assess acid-tolerance among indigenous Norwegian strains of brown trout. work, comprising both laboratory and field studies, has involved the restocking subsequent test-fishing thirteen lakes with five trout strains. There considerable variation ability individual support adult This did not appear related ANC (acid neutralising capacity) or any single chemical factor. One strain, Bygland, found be relatively acid-tolerant, accounting for more than 60% all fish recaptured by over 1990–1994. is consistent better survival young life-stages Bygland compared that other strains, experiments employing acidic conditions. Strainspecific differences calcium metabolism may physiological basis acid tolerance.
