Introduction: Perch is an economic and native species of the Caspian Sea. There are 159 species of fish in the Caspian Sea, some of which are capable of aquaculture. Aquaculture requires quality broodstock. Therefore, in introducing new species to the aquaculture industry, the first step is breeding. Providing white perch broodstock for reproduction, producing domesticated offspring, and introducing this species as a new species in aquaculture is a necessity. The purpose of this research was to obtain a technique for producing domesticated white perch broodstock with hand-fed and reproductive capabilities.
Material and Methods: This research was conducted during 2010 and 2011 as a single species in fiberglass tubs with a volume of 4 m3 and using well water. physical and chemical factors of water, growth factor, feed conversion ratio, and survival were measured. The broodstock were fed with extruded sturgeon feed daily at a rate of 3 to 5 percent of body weight.
Result and Discusion The temperature of the breeding tanks during the sampling periods was recorded in the range of 16.5 to 29 0C and other physical and chemical parameters of the water were within the permissible limits. The results showed that the average final weight obtained in 1400 was 534.181±51.18 gr. Also, in this study, the survival rate was 85 percent, the specific growth rate was 0.27±0.48, the feed conversion ratio was 1.67 kg, and the weight gain percentage was 11.4 percent. The gonadal index of the female fish was 4.95, the relative fecundity was 350-480 eggs per gram of body weight, and the maximum and minimum weight of the female gonad was between 11 and 29 gr.
Conclution: The results showed that the reproduction of white perch in an enclosed environment is achievable. Continuing to breed white perch over several generations, selecting this species for better growth, and producing specific perch food are among the most important factors in the success and introduction of this species to the country's aquaculture industry. |
