Abstract

Tilapia fish (Oreochromis niloticus) is one of the most widely cultivated freshwater fish species in Indonesia. The main problem in the cultivation of tilapia fish is mostly caused by the high number of mortality at the larvae stage which is largely due to the unavailability of the right feed. Natural feed is the most suitable feed used as larvae feed because it is easily digested and contains proteins that support the growth of larvae. This study aims to determine the effect of different natural feeding on the growth and survival of tilapia larvae. The method used in this study was a Complete Randomized Design (CRD) with three treatments and three replications: Tubifex sp. (T), Daphnia sp. (D) and Infusoria (I). The results showed the highest growth was in the treatment Tubifex sp. (T) with a length of 2,1 cm and an increase of weight is 0,31 gram, followed by Daphnia sp. (D) with a length of 1,6 cm and an increase of weight is 0,24 gram, and the lowest growth was in the Infusoria (I) treatment with 1,3 cm in length and 0,21 gram weight increase. The highest survival rate was found in Tubifex sp. (T) 93,06 %, then Daphnia sp. (D) 90,28 %, and the lowest in Infusoria treatment (I) 84,72 %. Feeding with different natural feed effect the growth of fish, but do not effect the survival rate of tilapia fish larvae.Keywords : Natural Feed, Fish Tilapia Larvae, Growth, Survival

Abstract

Catfish (Clarias sp.) is one of the fresh water species that is economical and one of the main comodities of aquaculture in Indonesia. Fulfillment the increasing of needs of community required cultivation supported the availability of adequate larvae with efficiency of feed production cost with the right feeding frequencies. This research aims to know the influence of the frequency of natural feeding silk worm (Tubifex sp.) towards growth and survival of catfish larvae. The method used in this study was a complete randomized design (RAL) with three treatments and three replications, as follows: P1 (feeding frequency 3 times a day), P2 (feeding frequency 4 times a day) and P3 (feeding frequency 5 times a day). The result showed that the different feeding frequency treatment had a very significant effect on growth but did not significantly affect the survival of larvae of catfish. The best feeding frequency in increasing larval growth and survival of larvae is P3 (feeding frequency 5 times a day) treatment with larval length increase of 3.6 cm and weight increase of 0.928 g.Keywords : Larvae of Catfish, Silk Worm, Feeding Frequency, Growth, Survival

Abstract

Betta spendens has a really high market price, the successful of betta spendens aquaculture on larvae stage depends of some factor, one of the factor is natural feed feeding in attempt to increase the growth. This research aims to determine of influence of different natural feed feeding towards to increase of growth and survival rate. The method used in this research was randomize complete design with 3 treatment and 3 replication following, T Treatment (Tubifex sp feeding), D treatment (Daphnia sp feeding), dan I Treatment (Infusoria feeding). Data was analyzed with Analysis of Variance (ANOVA) if there is a significant effect will be continue with BNT test. The best growth was on Tubifex sp. treatment with the increase of length from 0.7 cm to 1.7 cm and the growth of weight from 0.03 gr to 0.21 gr.Key Words : Growth, Larvae (Betta splendens), Tubifex sp., Daphia sp., Infusoria

Abstract

Catfish is one of the freshwater fish that has developed cultivation in the community because it can be cultivated in limited places and high density and has the advantage, fast growth and resistance to disease. The speed of fish growth rate is strongly influenced by the type, quality and management of feed given and environmental conditions. The study were used Completely Randomized Design (RAL) with 3 treatments and 3 replications, as follows: P1 (Time feeding 3 times daily), P2 (Time feeding 4 times daily) and P3 (Time feeding 5 times daily ). The data were analyzed using Analysis of Variance (ANOVA), followed by the Smallest Significant Difference (BNT) test. The results showed that the frequency treatment of different feeding significantly affected the growth but did not significantly affect the survival of catfish. The best feeding time in increasing the growth and survival of catfish is P3 treatment with larva length increase of 8,0 cm and weight increase 32,24gr.Keywords : Clarias sp., Feeding Time, Growth

Abstract

Catfish beeding is mostly done by using intensive system. The rate of fish growth is strongly influenced by the type and quality of feed given and environmental conditions. If there are sufficient good quality feed given and suppated enviroment, it can be ascertained assured that fish of growth to will be fast. This research was done in UPTD. Tuntungan Fish Seed House in April to Mei 2018, which aims to determine the effect of fermented feed on the growth and survival of catfish. The study used Completely Randomized Design (RAL) with 3 treatment and 3 replications, as follows: V1 (viterna 20 ml / kg), V2 (viterna 40 ml / kg) and V3 (viterna 60 ml / kg). The data were analyzed by using Analysis of Variance (ANOVA), if there is any effect of treatment continued with the test of the Smallest Real Difference (BNT). As the result the most effective dose is 40 ml/kg. The research shows that the fermentation of feeds has different effect on the real growth but does not significantly affect the survival of the catfish.Keywords: Catfish (Clarias sp.), Viterna Probiotics Feeding Frequency, Growth

Abstract

Penelitian ini bertujuan untuk mengetahui besarnya biaya dan pendapatan usaha budidaya udang vannamei, studi kelayakan usaha budidaya, dan menganalisis kenaikan biaya variabel pada usaha budidaya udang vannamei. Penelitian ini dilakukan pada bulan Maret-Mei 2018. Hasil penelitian yang diperoleh yaitu ; 1) Total biaya usaha budidaya udang vannamei sebesar Rp. 1,362,489,494 dan total pendapatan sebesar Rp. 828.810.506, 2) Studi kelayakan finansial usaha budidaya udang vannamei di Tambak Udang Alam Laut Lestari menghasilkan R/C Rasio sebesar 1,61 , B/C Rasio sebesar 0,61, break event point (BEP) terbagi atas 2, yaitu BEP Produksi/volume dan BEP harga. BEP Produksi/volume mendapatkan nilai sebesar 17.127 kg, sedangkan BEP harga mendapatkan nilai Rp. 54.218 dan payback period (PP) dalam jangka waktu 1 tahun 2 bulan. 3). Hasil analisis sensitivitas dan switching value, kenaikan biaya variabel sebesar 3% masih bisa ditoleransi, namun kenaikan biaya variabel sebesar 61% maka Tambak Udang akan mengalami kerugian.
