EXPERIMENT ON ARTIFICIAL REPRODUCTION OF BROCCOLI (Trichogaster Lalius) WITH HCG AT DIFFERENT DOSAGES

Abstract

The trail on artificial reproduction of dwarf gourami(Trichogaster lalius) with HCG at different dosages is to identify the maturation ability of Gophers (Trichogaster lalius) and compare the influence of HCG at different doses on the reproductive efficiency of dwarf gourami.The experiment consisted of 4  treatments (NT): 3000UI(NT1), 4000UI(NT2), 5000UI(NT3), 6000UI/kg(NT4) females. Each treatment was repeated 3 times. The results showed that during the  conditioning process, environmental factors such as temperature and pH were in the appropriate range for the maturation process of broodstock. The highest maturation rate is 40% in females and 45.83% in males. The survival rate in the conditioning process was quite low at 88.33% in males and 66.67% in females,  which however did not affect the results of the experiment. For stimulation to reproduction by HCG at different doses, the fertility rate fluctuates from 33.33% - 66.67% fertility ability ranges from 268.56 to 389.72 eggs / g female, fertilization rate 61.50%, and hatching rate 98.71%. The most appropriate dose of HCG for  broccoli is 4000UI and the highest fertility of the four treatments is 389.72 eggs/g females.
