ABSTRACT

During the Spring of 2006, 12 pools, each one measuring 125 cm in every size and 35 cm deep have been set up for the outdoor breeding of several Cyprinodontid species in which the SEI is interested. The useful volume in every pool is slightly over 400 l and their surface accounts for 1,5 sq. m. Regarding our former experiences, we are looking forward to good results and obtaining a good yield of juvenile fish in every pool. This way of breeding may be considered as seminatural since the fish are not fed very often. Refuges such as old tiles or stone piles were placed in each pool. Filamentous algae serve both as laying substrate and food for the fish. Most of the pools have also water lilies. During the Summer, a shading sheet will prevent excesive temperature and therefore water evaporation. The species collected in Turkey by the SEI members (see GEVA) have been favoured in this project, such as Aphanius anatoliae anatoliae, A. anatoliae sureyanus, A. anatoliae transgrediens, A. mento and A.villwocki. Other species that are being kept by SEI members since some time ago are also breeding in the pools: A. asquamatus, A. apodus, A. sirhani, A. saourensis, Cyprinodon alvarezi, etc. FULL TEXT OF THE PROJECT : English
