FISHERY SPITSBERGEN

An Arctic char observed in a glacial Spitsbergen river

An anadromous Arctic char (male) was recorded in southwestern Spitsbergen, in a very muddy glacial river, in August 2008. This is apparently the first specimen of this species observed in such an unfavourable habitat in Svalbard. Arctic char (Salvelinus alpinus), the only freshwater native fish in Svalbard, is rather common (occurring in more than 100 lakes and watercourses) and is differentiat...

Assumption and realization of Arie catchment measuring system, Spitsbergen

Geoecosystems of polar areas are particularly sensitive to climate change. The fluctuations of mean annual temperatures of Svalbard areas recorded for many years and progressing glacier recession indicate unequivocally that the Arctic areas strongly react to long-term weather and climate changes. Energy released in the form of proglacial waters contributes considerably to the transformation of ...

An Individual-based Fishery Model and Assessing Fishery Stability

The stability of a fishery system was investigated using two forms of a stochastic computer simulation model that was individually based in terms of the fishing boats. Fish catch was partitioned among boats according to two catch processes: an unranked process in which all boats had equal ability to catch fish and a ranked catch model in which a boat’s ability to catch fish depended on its weal...
