Social organization and territoriality in brown trout juveniles during ontogeny

  • Chapter
  • First Online:
Biology and Ecology of the Brown and Sea Trout

Abstract

The first studies of salmonid population dynamics have shown the determining role of behavioural factors, particularly competition for space and food in the limiting of natural populations and their distribution (Allen, 1969; McFadden, 1969; Le Cren, 1973). This role of behaviour and competition in the biology of populations and its consequences on fish production appears to be especially marked for the brown trout, Salmo trutta L., a strongly territorial salmonid species in freshwater lotic environments (Onodera, 1967; Noakes, 1978, Thorpe, 1982).
