Abstract:
Using Statistical Analysis `the obtained data in this study were subjected to one-way (ANOVA) analysis of variance (snedecor,and Cochranl, 1986),(Sokal,and Rohlf,1981). Data were entered and analyzed using Statistical Package for Social Sciences program (SPSS) for Windows, Version 16 (Log Xact8 ,Cross over,USA),
This study was conducted to see the effect of hormones for brood stoke catfish in the intensive farming system through three types of hormone HCG, Ova prim and carp pituitary gland powder to release the eggs from brood stock catfish. It was evaluated average fecundity, weight and length for brood stock that have been injected. Were obtained the following results at GSI account in hormone formulations of purified were GSI = 3.27 for Ova prim hormone, HCG hormone = 2.91 and pituitary gland of carp = 1.91, the average weights of brood stock that have been injected with 500 HCG, 540 Ova prim and 485 for pituitary gland powder the average length and weight fry (5.85 -101.38) (1.56-5.655) (1.78-5.77) for Ova prim, HCG and pituitary gland powder of fish carpRespectively
It has to examine the relationship between fecundity and length and weight, and found that there is a high significant difference in fecundity between the fish that has them three hormones while no significant difference in length and weight, were also investigated the correlation between weight and length for fry showed a significant difference strong for each frybest ratio trace length and weight hormone HCG (93.5%), hormone Ova prim (90.3%) and powder pituitary hormone carp (87.6%).
Through this study, we can obtain a suitable fry from these three hormones in intensive farming system conditions and it can be rearing till marketing size.
