Extensive Information
With agriculture, extensive farming occurs on low value marginal land with a low stocking density per area of production. The same is true for extensive aquaculture where the stocking densities are low per unit of water volume. Within the New Zealand context we would envisage extensive aquaculture to occur in ponds, reservoirs and possibly constructed coastal lagoons on private property.
Extensive and semi-intensive aquaculture usually relies on producing cheap feeds (algae and zooplankton) that the cultured species consume within the culture system. Often, supplemental feeding of pelleted feeds is required to improve growth rates (especially in semi-intensive farming). In some instances (i.e. biofuel production) the algal biomass is harvested directly from the pond.
