Effects of Some Feed Suplements Types to the Growth of Javaen Barb/Brek Fish (Puntius orphoides) Second Filial as Domestication Product

Abstract

Aquaculture can be improved by a diversified approach in the form of domestication research of a wild fish. The research has been done by cultivating Javaen Barb/Brek (Puntius orphoides) from Serayu river, Banyumas at a natural pond and laboratory scale. Brek fish is relative slow in growth and development of gonad. This research is aimed to determine: (1) the rate of general growth of Brek in the provision of some kinds of additional food; (2) Relative Growth Rate (RGR); (3) Specific Growth Rate (SGR) and Feed Conversion (FC). The research used experimental methods. The method was a completely randomized design (CRD) of 4 treatments and 3 replicationsof: A = 100% pellet; B = 70% soybean sprout and 30% pellet; C = 70% Ipomoea aquatica leaf and 30% pellet; D = 35% soybean sprouts, 35% I. aquatica leaf and 30% pellet. Quantitative data were analysed by analysis of variance (ANOVA) of the fishes growth.The results show influence of feed types to the Relative Growth Rate (RGR) of Javaean Barb. The best RGR with the value of 72.40 was given by feed types in the D combination. Meanwhile, Specific Growth Rate (SGR) and Feed Conversion (FC) were not affected by the feed types. The study were expected to provide suggestions for efficient feeding techniques in attempts at domestication of wild fish. How to CiteSusatyo, P., Sugiharto, S., Hana, H., & Chasanah, T. (2016 METHODSJavaean barb, pelleted feed, soybean sprouts and Ipomoea aquatica. The fishes were selected from the maintenance pool (stem stock as product of our earlier research (Susatyo et al., 2009;Susatyo & Sugiharto, 2010). The selected fishes were the second filial/F2 with an average length of 14 cm and an average weight of 35 grams.Prepared as many as 12 pieces aquarium with size of 75 x 50 x 60 cm . Wells filled with water as high as two-thirds , and were equipped with aeration adequate and stable. Each aquarium was dotted with 10 Brek fish measuring an average length of 14 cm and an average weight of 35 grams. Brek fish to this growth test were the result of the sorting of the F2 stock (which was partly used as a parent for test gonadogenesis test and spawning test, some with have size of an average of 35 grams were used as the material of growth test).The analysis was Testing of their growth is an experimental test with a completely randomized design (CRD), 4 treatments and 3 repetitions. The treatments were tested consisting of : A = feed with 100 % pellets B = feed with 70 % of soybean sprouts and 30% pellets C = feed with 70 %of Ipomoea aquatica leaf and 30 % pellets D = feed with 35 % of soybean sprouts, 35 % I. aquatica leaf and 30 % pellets The feeds were given amount of 4 % of the weight of the biomass with combined percentage of feed. The amount of the feeds were given in every two weeks. Frequency of feeding was twice a day (08:00 AM and 16:00 PM).The feeds were given by way of stocked (for pellets and soybean sprout), to soybean sprouts were made a little bruised before it is given) and with a hanging method of I. aquatica leaf.The obse...

Protease and Amylase Activities of Javaen barb (Systomus rubripinnis Val.)

“…This fish has a medium body with a total length of up to 250 mm with the last spine on the dorsal fin with 30 teeth and has a caudal fin with black top and bottom edges (Kottelat et al, 1993). Preliminary studies of Javaen barb have been carried out, such as studies of several aspects of Javaen barb spawning in the Klawing Purbalingga river, Central Java (Suryaningsih et al, 2012), and studies on the growth with different feedings (Susatyo et al, 2016). However, studies on the performance of digestive enzymes, especially proteases and amylase, have never been carried out, so research on this matter is urgent.…”

Reproductive aspects of javaen barb fish, Systomus orphoides in the initial domestication program

“…Sundaland, Sumatera, Java, and Borneo in Indonesia are home to this species (Djumanto et al 2013;Herawati et al 2020). Several investigations found S. orphoides in the Serayu River in Central Java, Indonesia (Sustyo et al 2016).…”

“…gambaran hasil pengamatan mikroskopis dari jenisjenis leukosit dianalisis secara deskriptif.HASIL DAN PEMBAHASANBerdasarkan hasil penelitian, dari kegiatan penangkapan ikan Familia Cyprinidae di Sungai Banjaran, Banyumas didapatkan tiga species ikan, yaitu Ikan Nilem (O. vittatus), Ikan Brek (B. balleroides), dan Ikan Lunjar (R. argyrotaenia). Menurut penelitianSusatyo, et al (2016) bahwa spesies tersebut merupakan Familia Cyprinidae yang termasuk ikan indigenous yang berada pada Sungai Banjaran. Disekitar pengambilan sampel pada daerah Hulu Sungai Banjaran terdapat banyak naungan pohon dikarenakan kanan kirinya hutan, dasar sungai berpasir, berbatuan besar, dan sungai cukup dalam.…”
