ABSTRACT:The ADONIS: CE software has been used for two fish species, Cottus gobio, of conservation interest and Salmo trutta fario, of economic interest, to design an on-site (upper Târnava Mare River) adapted support-system model for management decision-making. Habitat needs and indicators of favourable conservation status have been investigated, pressures and threats to these fish species have been determined, and management elements have been suggested. This management system allows the proper organization of management measures for the renaturation of the local natural fish associations in the local brown trout zone.

Diversion of fishing pressure on the economically important species Barbus barbus (Linnaeus, 1758) to protect the Community interest congeneric Barbus meridionalis Risso 1826, based on a decision-support management system.The ADONIS:CE instrument has been used in the field of congeners species, Barbus barbus -of economic interest and Barbus meridionalis -of conservation interest, to build a support-system model for management decision-making. Analysis of the habitat needs and the indicators for favorable conservation status have identified pressures and threats to these fish species for which management actions have been proposed. This management system favors the decrease of fishing pressure on Barbus meridionalis species by its transfer to Barbus barbus species. REZUMAT: Devierea presiunii pescuitului asupra speciei importante economic Barbus barbus (Linnaeus, 1758) în vederea protejării speciei congenere de interes comunitar Barbus meridionalis Risso 1826, pe baza unui sistem-suport de luare a deciziilor de management. ZUSAMMENFASSUNG: Das Umlenken desInstrumentul ADONIS:CE a fost utilizat în domeniul protecţiei speciilor congenere, Barbus barbus -de interes economic şi Barbus meridionalis -de interes conservativ, pentru construirea unui model de sistem-suport pentru luarea deciziilor de management. Au fost analizate necesităţile de habitat, indicatorii care relevă statutul de conservare favorabil, au fost identificate presiunile și ameninţările asupra acestor specii de pești și au fost propuse acţiuni de management. Acest sistem de management favorizează scăderea presiunii pescuitului asupra speciei Barbus meridionalis prin transferul acestuia asupra speciei Barbus barbus.
