“…For dace, reproduction is preferentially at temperatures between 7°C (Mann, 1974;Philippart, 1981;Millet, 1989) and 12°C (Mann, 1996;Kucharczyk et al, 2008); seven references give optimum temperatures between these limits (Kennedy, 1969;Lelek, 1987;Philippart et al, 1989;Bourgeois, 1963 in France, in Wüstemann andKammerad, 1995;Poncin, 1996 on the Meuse, Belgium; Herzig and Winkler, 1985 in the laboratory, in Küttel et al, 2002;Teletchea et al, 2009b). It apparently remains possible between 5°C (Alabaster and Lloyd, 1982;Mann, 1996;Kucharczyk et al, 1998) and 16.5°C (Mills, 1980in Millet, 1989 in the laboratory).…”
