Abstract

The main fish farming activities at the enlargement stage require a feed cost of around 60% of the total production cost. Efforts that can be made to reduce the cost of feed are through the starvation and fermentation of feed. This study uses a Completely Randomized Design (CRD) which is 3 treatments and 3 replications.  The treatments tried were treatment A = protein feed 31-33% without fermentation (daily feeding), treatment B = protein feed 21-23% fermentation,, (daily feeding), treatment C = protein feed 21-23% fermentation, (1 day starvation 1 day re-feeding), treatment D = protein feed 21-23% fermentation, (1 day starvation 2 days re-feeding), E treatment = protein feed 21-23% fermentation, n (1 day starvation  3 days re-feeding). The study was conducted in a walled pond which was sealed using a net (50 x 50 x 100 cm3), feeding 3 times a day. The results showed that the treatment E effectively suppressed the FCR value and offset the daily growth rate of Treatment A. In addition, treatment E has the same FCR value as treatments B, C, D but treatment E has a higher daily growth rate.Keywords: starvation, fermentation, growth, FCR

Abstract

Salah satu  metode sex reversal  yaitu perendaman yang  dilakukan dengan cara bahan yang digunakan dicampur kedalam air selanjutnya telur atau larva ikan direndam didalamnya. Saat ini bahan buatan (komersil) untuk kegiatan sex revesal mulai dikurangi penggunaannya karena dinilai tidak ekonomis dan memiliki dampak negatif terhadap lingkungan dan  kesehatan manusia yang mengkonsumsi ikan hasil sex reversal, sehingga dalam penelitian ini kegiatan sex reversal menggunakan bahan alami madu dan air kelapa. Penelitian ini dilaksanakan  di Laboratorium Terpadu Universitas Madako Tolitoli, selama 3 bulan yang terdiri dari 1 bulan pertama persiapan alat dan bahan, kemudian 2 bulan selanjutnya pelaksanaan penelitian (pemeliharaan dan identifikasi).  P0  (Kontrol (tanpa pemberian madu dan air kelapa), P1 (Konsentrasi madu 5 ml/L fase larva umur 5 hari), P2 (Konsentrasi madu 5 ml/L fase embrio), P3 (Konsentrasi air kelapa 100 ml/L fase larva umur 5 hari), P4 (Konsentrasi air kelapa 100 ml/L fase embrio).  Hasil Penelitian menunjukkan perlakuan di ujikan berpengaruh secara signifikan (p>0,05).   Semua perlakuan perendaman madu dan  air kelapa pada  fase embrio dan larva menunjukkan  persentase terbaik.Kata kunci : Ikan cupang, maskulinisasi, madu, air kelapa, embrio, larva

Abstract

Success in the fish hatchery is influenced by natural feed. One of the natural freshwater feeds that have a high nutritional content and is easy to cultivate is Daphnia magna. The availability of D. magna at any time must be supported by daily feeding. Ulva lactuca macroalgae is one of the ingredients that have the potential to be used as D. magna feed because it has good nutrition and is abundantly available on the coast. This research was conducted for 17 days at the Integrated Laboratory of Madako Tolitoli University. The aim of the study was to determine the population growth of D. magna fed          U. lactuca. D. magna was reared in a 25 x 25 x 30 cm aquarium containing 5 liters of green water and a stocking density of 20 individuals/L. The treatments tried were Treatment A = Without U. lactuca Soak (0 ml/L), Treatment B = U. lactuca Soak (3 ml/L), Treatment C = U. lactuca Soak (5 ml/L). The results showed that the administration of U. lactuca 5 ml/L (804.44 ind/L) had the highest population growth compared to the treatment of 3 ml/L immersion of U. lactuca (597.78 ind/L) and without administration of immersion of U. lactuca (482.22 ind/L). Treatment of U. Lactva 5 ml/L is effective in increasing Growth D. Magna and can be an alternative feed D. Magna whose availability is abundant in the coastal area.Keywords: Daphnia magna; growth; Ulva lactuca
