Effects of dietary superworm (Zophobas morio) oil on growth and reproductive performance of female zebrafish (Danio rerio)

Abstract

There was not different effect on the growth performances between female zebrafish (Danio rerio) after feed with fish oil and superworm oil (Zophobas morio). Feed conversion ratio, weight gain and specific growth were not significantly different between the two groups of fish fed the different type of oils. There was not statistically significant difference on the reproductive performances. Gonadosomatic index was not significantly different between two groups of fish fed the different type of oils. The relative expression of ovulation-inducing genes including ptgs2a, sik1, and slc37a4a were not significantly differed when compared between female zebrafish after feed with fish oil and superworm oil. Results suggested that superworm oil may be used in female zebrafish diet with no adverse effects on both growth and reproductive performance.
