Fishery resources
Capture fisheries resources are highly diverse. FAO landing statistics refer to about 2 500 species or group of species most of which are finfish. By far the most numerous fish species, and those most important to aquaculture and fisheries, are teleosts, or bony fish , which in the sea extend from small "grazing" species such as anchovy to large active predatory fish such as tuna. A similarly wide range is also found in freshwater, with the most important species from a production point of view belonging to the carp family. These account for over half the total of inland waters fisheries production.
Marine capture fisheries resources are usually considered close to full exploitation worldwide with about half of them fully exploited, one quarter over exploited, depleted or recovering from depletion and one quarter only with some capacity to produce more than they presently do. The overall situation of inland capture fisheries resources is not as well known but is likely to be as serious or worse , considering the much larger environmental impact they are subject to.

According to several folk tales, it is also in these valleys, woods and bogs that Old Nick found refuge.The great variety displayed in the nature is also reflected in the local cultural heritage. At the beginning of the 19th century growing linen spread and became the basis of the legendary wealth of Mulgi farms.
