The assessment of the state and maximum bioeconomic sustainable yield of pelagic and demersal resources in the central Adriatic

Abstract

         Taking into account the methodology of production model (Fox, 1970) and available fisheries statistic data: annual catches of pelagic and demersal, (bottom trawl and coastal fisheries) fish, crustaceans and cephalopods popula­tions, of cooperative and private fishing sectors in the cen­tral Adriatic, as well as estimated fishing effort for the year it has been tried to estimate the following bioeconomic factors, for management purposes of:

           - sustainable yield of existing pelagic and demersal resources of the central Adriatic;

          - to assess the possibilities for a higher catch produc­tion (yield), as well as to optimize fishing effort.

         In this study statistic data of total yearly pelagic and demersal species catch have been considered from Republic Statistics Departament, while more precise statistical data od one cooperative, »Jadran« - Split, taken as »represen­tative statistics samples« have been used in calculating estimation of total fishing effort for purse-seining and trawling fishing operations for fifteen years period.
