ABSTRACT
A vegetated spawning habitat with contiguous vegetated nursery areas has been shown to be crucial for optimal pike reproduction. The drastic historical loss of wetlands has created a serious need for habitat restoration measures of former pike reproduction habitats to strengthen weakened pike populations. There has been a long tradition of improving pike populations through habitat restoration in North America restoration efforts have also been carried out in Sweden and Denmark. Efforts to restore pike populations through habitat manipulation have usually focused on spawning habitat for example, controlling the water level to create managed pike spawning marshes. Habitat restoration for pike has in general focused on spawning habitats. Digging in the pike factory should be restricted to prevent loss of spawning habitat and spreading of sediment in the spawning areas, since pike eggs are highly sensitive to siltation. Constructing pike factories is an efficient way of strengthening pike populations if spawning habitat is limited.
