A series of studies on the ecology of the bullhead, Cottus gobio is described. Habitat choice, growth rate and longevity, population density, biomass and production, reproduction, life history and feeding is compared at 8 sites in England and 1 site in Wales. Evidence suggests that in Cottus gobio the prevailing environmental conditions result in considerable modifications in longevity, growth rate and egg production. It also indicates that the advantages of fast growth and high reproductive effort in favourable habitats are offset, at least partially by increases in mortality.Page Range
