حفظ خزانه ژنی ماهیان خاویاری رودخانه سپیدرود

In order to implement the project properly and to collect appropriate numbers of sturgeon brood stocks from the Sepidrud River, several administrative coordination meetings have been conducted as well as communication established with relevant government organizations. Information to the fisher community and inhabitants in the vicinity of the Sepidrud River through personal contact and through printing and publishing of brochures has been disseminated. Also a contract has been signed with local fishers to ensure delivery of live spawners of sturgeon for the project. A well equipped team was set up to catch sturgeon spawners in the spawning season in spring and autumn in the Sepidrud River estuary. Procurement of transfer equipment to confine spawners, and all spawners have been kept in separate concrete tanks with freshwater until the time of artificial breeding. Totally 15 breeders of A.stellatus ( 9 specimens) and A. persicus (6 specimens) were collected which shows that coordination and bringing local organization and fishermen is effective measures to save critical endangered sturgeon stocks in the spawning sites. Artificial breeding of spawners using micro incision is an effective ways to save the rare breeders alive for the future. It is necessary to tag all sturgeon spawners and adapt them in captive condition. Rearing larvae and fingerlings up to 30 grams for release in the Caspian Sea showed a better tools increase the release efficiency. Construction of Sperm, DNA and Tissue banks from all breeders can be a suitable model of rare species conservation. Brood stock establishment through selection methodology can save resources both for future rehabilitation and aquaculture extension. Molecular genetic analysis conducted using Microsatellite markers and specific markers were developed for each of the crossings. To show the results and outcome of the project via organization a national as well as Regional workshop being consider an effective tools and as a model to SAVE STURGEON SPECIES in the CASPIAN SEA. Such model can practically work if the local, national and regional authorities continue such project in their region at least for next 20 years to recover genetic resources of each stocks at least for 10 generations. Public awareness and their active involvement is key point for success of the sustainable management and conservation program.
