Ein Modell der mathematischen Optimierung zur Bestimmung der optimalen Größe und Struktur der deutschen Fischereiflotte unter stochastischen Bedingungen

A mathematical model to optimize the German fishing fleet is draftet and it’s data basis is described. The model has been developed by Brodersen, Campbell and Hanf in 1994 to 1998. It could be shown, that this model is flexible enough to be applied successfully to a lot of very different political questions, if adapted accordingly. The economic consequences of measures of fishery politics, the effects of technical advances, but also increasing incertainties can, to some degree, appropriately be assessed quantitatively. Finally it could be shown that, principally, the available account of data is a good basis for investigations into fishery economics and fishery politics. However there is a need to treat the source of data continuously and competently in order to make these informations available quickly. Statistical data to reflect the fishery sector are valuable. However, they obtain their full value only when judged by experts from the fishing industry, biology and technical fishery research.

Struktur und Fänge der deutschen Fischereiflotte

In order to carry out the Multi-annual Guidance Programmes (MGP) the national fishing fleets of the EU were divided into mostly homogenous fleet segments. The current paper describes the single segments of thc German fishing fleet and summarizes their characteristics such as vessel capacity (tonnage in GRT), machine performance (power in kW) and vessel size (total length in m). Another table lists the averaged landings separated per stock and segment for the period from 1990 to 1994.
