摘要

这项研究有望为养鱼户提供鲶鱼(Clarias gariepinus)养殖的额外信息。采用完全随机设计(CRD)的试验方法,共5个处理,3个重复,即:P1 =浸泡芒丁亚叶提取物废弃物1分钟,P2 =浸泡3分钟,P3 =浸泡5分钟,P4 =浸泡7分钟,P5 =浸泡9分钟。在廖内省伊斯兰大学农学院鱼类种子中心对鲶鱼亲鱼进行人工产卵,共获得鲶鱼卵2.250枚。使用的容器是一个10升大小的罐子。本试验研究了不同浸泡时间对鲶鱼幼虫孵育时间、孵化率和存活率的影响,结果表明浸泡时间为P5,即浸泡时间为9分钟。实验结果表明,孵育时间为17小时24分钟(17小时24分钟),孵育率为87.78%。而本研究的水质测量结果被认为是最适合鲶鱼养殖的,氨范围为0.27-0.75 ppm, DO范围为3.14-4.95 mg/l,温度为28-31°C, pH为6.5。

Pengaruh Lama Waktu Perendaman Limbah Ekstrak Daun Kersen (Muntingia calabura) Dengan Dosis Sama Terhadap Lama Inkubasi, Daya Tetas dan Kelulushidupan Larva Ikan Lele Dumbo (Clarias gariepinus)
This research is expected to be useful for fish farmers as additional information in catfish (Clarias gariepinus) aquaculture. The method used is an experimental method using a completely randomized design (CRD) with 5 treatments and 3 replications, namely:P1 = 1 minute immersed in Muntingia calabura leaf extract waste, P2 = 3 minutes immersed, P3 = 5 minutes immersed, P4 = 7 minutes immersed and P5 = 9 minutes immersed. 2.250 eggs of catfish (C. gariepinus) were obtained from artificial spawning of catfish broodstock at the Fish Seed Center, Faculty of Agriculture, Islamic University of Riau. The container used is a jar with a size of 10 liters. Based on the results of research on the effect of immersing waste extracts of M. calabura leaf extract with different immersing times on incubation time, hatchability and survival of catfish larvae, the best treatment was P5, which was 9 minutes of immersion. The parameter results obtained were 92% of egg adhesive, incubation time is 17:24 (17 hours 24 minutes), and hatchability rate is 87.78%. While the results of water quality measurements in this study were classified as optimal for catfish cultivation, with an ammonia range are 0.27-0.75 ppm, DO ranged from 3.14-4.95 mg/l, temperature are 28-31°C and the pH is 6.5.
