Investigation gatan propagation Barbus xanthopterus
This survey carried out during 3 years.We surveied posibility of artifishial hatching of Gattan(Barbus xanthopetrus).We fished brood stocks from Karkheh river and transferd them to fresh water hatcharies. We held some of brood stocks in pond and the rest were treated with hormons.We used PG as a couse in the first year.Also pure LRHA and compound of LRHA with PG or pure GnRH with metacholrooramid were used in next years. The quantity of esperms were increased after using hormon and many of female which were injected with PG became fertile. Injection of hormons carried out in one stage or two stages with 10-12 hour interval.In the third year of the project because of existence of enough brood stocks;our test were more completly..We used PG hormon and other artificial hormons for 26 femals brood stocks.15pieces or them became fertile;then handing spowning carried out on them. Larves transfered 6 days after development stages.47000 larves transfered to pond and fed with SFC They reached to 172 mg in weigth and 28 mm in length after 30 days.
