Culturing of mullet fingerlings species Mugil cephalus L.

Abstract

The grey mullet is referred as the scientific name "Mugil cephalus" mugil cephalusis most important of species culture of many areas in the world. To obtainable of the procedure culture in the climate of our county (Iran), we executed a project of fingerlings mugil cephalus from 1994 to 1991 Where as our county was lack of fry, therefore, we purchased 2000 specimens of fry from Hong Kong. In order to we imported fry and they were transported into shaheed Marjani farm, by chiller track we provided a house green and then fries enteredinto fiber glas tankes that the dimension of fiber glass tanks were 2* I *2m but the conceret ponds were 3* I *2m during the manitenance of fry in tanks, in addition toremoving of stress due to transportation quarantine, the manual feeding offered torice bean plus wheat flour and also zoea of live food (Daphani plus Artemia) fry adapted to fresh water (1ppt) and estuary (14ppt) and then, they moved into the earth ponds. The species determinant and biometry were occurred to 30specimens of fry during the maintenance of fry in tanks, the climate condition for temperature and submitting of ponds the earth ponds were limed. And water flow, we were fertilized to chemical and animal fertilizers, there are full of these materials. After the earth ponds were obtained them. The earth ponds have high produced natural production. The experiment was performed on fry with hapas, the survey of survival and the final introduction of fry were transferred in to the earth ponds. This pond included in 5000 specimens. This pond has 4000areas in adjacent Ghomishan basin and also 1000 fry have placed in the earth ponds. These areas have 1000 m2 in Marjani farm, the average weight of fry was approximately 0/5 (gr) and the average Length was 0/4 (cm). During the maintenance of fry, fry were fed by live food and detritus that were achieved by fertilizer. Fry fed with supplement food, this function occurred by food container. The feeding times were fed 2 or 3 times in every day, the amount of food was based on dry weight, fry that calculated during culture. During culture, the control of physical and biological factors in the ponds were recorded and a few fish were captured. They performed on biometry the summery results achieved as follows: In the freshwater pond the average weights of valuable period in the end of culture included in 235 (y) and 668 (gr) respectively. The average lengths of fry (fork length) in the valuable period in the end of culture at first and second years contain 26 Cm, 37* I Cm respectively. In the saline water pond the average weights of fry in the valuable period in the end of culture are first and second respectively. The average lengths of fry in the valuable period in the end of culture are first and second years contain 26 cm and 35.2 cm respectively.
