【 摘 要 】

The success of high density catfish cultivation increases seed demand to support the cultivation. Seed cultivation supported by clean water system has succeeded in producing N1 (Nursery 1) seed. The aim of the research was to analyze the production return cost ratio (R/C) and benefit of N1 seed (Nursery 1) of catfish varieties sangkuriangthe on various egg density in tanks using filtration system. The research was conducted in The Catfish Teaching Factory of Fisheries and Marine Science Faculty, Diponegoro University, from December 2017 to February 2018. The research was performed on seeds ofSangkuriang catfish varietieswhich were hatched and being observed for 17 days. The method of the research was experimental method with three treatments and three repetitions, namely T1 (density of egg: 50gr), T2 (density of egg : 60gr), and T3 (density of egg: 70gr).The seeds produced were sold, The price was 40 IDR per fish, the total income was analyzed with ANOVA, then proceed with the least difference test. The result showed that seed production performance recorded asT1 yielded seed = 25,321 seeds;T2 = 23,874 seeds and T3 = 21.952 seeds. The price of seeds per individual is 40 IDR,the best total revenue is T1 = 1,012,840 IDR, -; and then T3 = 954,960IDR andT2 = 878,080 IDR. The total cost T1 = 366,217.3 IDR;T3 = 356,217.3 IDR and P2 = 346,217.3 IDR. R/C calculation results show T1 = 2.77; T3 = 2.68 and T2 = 2.54, reach R/C ratio ≥ 1 indicates that the production of N1 (Nursery 1) Sangkuriang catfish with different stocking density of eggs using filtration system or clean water system wasvery profitable.
