Perbandingan Jumlah Induk terhadap Keberhasilan Daya Tetas dan Kelulushidupan Larva Ikan Mas Koki (Carrasius Auratus)

Abstract

Hatchery fish have the prospect of local and export markets. One fish that has a high sales price and demand a fair amount of both local and export is a goldfish (Carrasius auratus). This study aims to get a good comparison of the amount of the parent for maximum spawning and determine the ratio of male and female parent goldfish different on hatching rate and survival of larvae. Research methods using completely randomized design with 3 treatments and 3 replications, with treatments 1 ratio of male parent and a female parent 2: 1, treatment 2 with a ratio of male and female parent 3: 1, and the treatment of 3 with a ratio of male parent female 4 1. This study be realized in July to August 2015. The results of this study indicate that the ratio of the number of aircraft significantly affect the degree of fertilization and hatching indicates the highest level obtained from the treatment 3 (82.87%) with a male female parent Comparing the 4: 1 which chances of sperm to fertilize an egg is greater so that the number of eggs that hatch will also be greater. The highest survival rate of larvae and also obtained from the treatment 3 (81.82%).
