Abstract
Viable North Sea (ViNoS) is an Agent-based Model (ABM) of the German Small-scale Fisheries. As a Social-Ecological Systems model it focusses on the adaptive behaviour of fishers facing regulatory, economic, and resource changes. Small-scale fisheries are an important part both of the cultural perception of the German North Sea coast and of its fishing industry. These fisheries are typically family-run operations that use smaller boats and bottom trawling gear to catch a variety of demersal species, foremost plaice, sole, and brown shrimp. Fishers in the North Sea face area competition with other uses of the sea—long practiced ones like shipping, gas exploration and sand extraction, and currently increasing ones like marine protection and offshore wind farming: German authorities released a maritime spatial plan implementing (1) the need for 30% of protection areas demanded by the United Nations High Seas Treaty and (2) aiming at up to 70 GW of domestic offshore wind power generation by 2045; the European Union is aiming to reduce fisheries in all Marine Protected Areas. Fisheries in the North Sea also have to adjust to the northward migration of their established resources following the climate heating of the water. And they have to re-evaluate their economic balance by figuring in the foreseeable rise in oil price and the need for re-investing into their aged fleet.
