Cacao pod husk (Theobroma cacao L.) is waste or by-products of agro-industry that was produced from cacao plants. The nutritional content of cacao pod husk consisted of 9,15% protein, 1,96 % lipid, 25,64 % crude fiber, 10,39% ash, and 52,86% nitrogen-free extract (NFE). Crude fiber from cacao pod husk was difficult to be digested by fish. The solution for that constraint was by applying fermentation proccess. This experiment was aimed to observe the influence of cacao pod husk flour which has been fermented first before added into the practical diets, on the feed efficiency and growth of carp (Cyprinus carpio). The trial fish used were carp (C. carpio) with an initial average body weight of 6,54 ± 0,07 g/fish. Feeding frequency applied was twice a day, i.e. at 08.00 a.m and 16.00 p.m. and by appliying an at satiation method. The fishes were cultured for 42 days with the stocking density of 1 fish/ 2L. The experimental method used was completely randomize design (RCD) with 4 treatments and 3 replicates. The treatment of A, B, C, and D were the trial diets with the concentration of cacao pod husk flour of 0, 10, 20, and 30%, respectively. The data measured were feed consumption, feed efficiency (FE), protein efficiency ratio (PER), growth (G), spesific growth rate (SGR), and survival rate (SR). The data showed that the use of fermented cacao pod husk flour in the diets resulted significant by effects (P<0,05) on the feed consumption, FE, PER,G, SGR, and SR. Treatment C resulted on the values of feed consumption i.e. 190.1±2.98g, FE i.e. 88.19±8.09%, PER i.e. 2.66±0.24%, G i.e. 7,26±0,11, SGR i.e. 1.68±0.13%, and SR i.e. 96,00±4,00%. The water quality parameters during this observe were varied between suitable range for fish life. It was concluded that the diet containing 20% of fermented cacao pod husk flour resulted on better feed efficency and growth of the carp.

PENGARUH PEMBERIAN TEPUNG CACING TANAH (Lumbricus sp.) SEBAGAI ATRAKTAN DALAM PAKAN TERHADAP TINGKAT KONSUMSI PAKAN, EFISIENSI PAKAN DAN PERTUMBUHAN IKAN PATIN (Pangasius sp.) Rizkiana Amalia; Sri Hastuti; Agung Sudaryono

Catfish (Pangasius sp.) is a dominant consumption fish and it is targeted that production will be increase every year. Catfish have a low feed efficiency value which is causes the growth of catfish to be less optimal, so it is necessary to add ingredient into the diets so that the fish are interested in eating the diets given. The use of earthworm meal as an attractant was expected to increase of feed consumption, feed efficiency and growth of catfish. This experiment aimed to study the effect of dietary earthworm meal as an attractant on feed consumption level, feed efficiency and growth of catfish (Pangasius sp.). The catfish used with an initial average body weight of 6,78±0,68 g/fish. The fishes were cultured in the aquarium for 42 days with the stocking dencity of 1 fish/2L. The experimental method used was completely randomize design (RCD) with 4 treatments and 3 replicates. The treatments were addition of earthworm meal (Lumbricus sp.) as an attractant with a dose of 0%, 5%, 10% and 15% in the diets. The data showed that the use of earthworm meal (Lumbricus sp.) inclusion in the diets resulted in significant effects (P <0,05) on feed consumption (159,73 g), FE (81.06%), PER (2,31%), G (9,76 g) and SGR (1,97%/day) but not significant effect (P>0,05) on survival rate (84.44-93,33%). The best food preference test in treatment C dose 10% of earthworm meal with percentage 44% fish approaching diets. The water quality parameters during this study varied between suitable range for the catfish (Pangasius sp.) life, i.e temperatures 27,70-30,900C; pH 7,00; DO 5,37-5,52 mg/L and NH3 0,0036-0,0095 mg/L. It was concluded that catfish (Pangasius sp.) fed with the diet containing 10% attractants of earthworm meal resulted in better feed consumption, feed efficiency and growth.

In aquaculture, Spirulina platensis is used as a feed supplement as it contains the amino acid phenylalanine. This study was conducted to evaluate the differences in the effects of spirulina-based microcapsules and commercial diets on the absolute, daily, and specific growth rates, as well as the survival rates, of milkfish larvae. The larvae were fed with Spirulina platensis as a core diet in microcapsules with different matrix (wall) compositions. The first capsule wall consisted of gelatin and fish oil, while the second capsule wall contained gelatin, fish oil, and whole egg. The control group was fed a commercial diet. A total of 1,200 larvae were used in this experiment using a recirculating system. The experiment was conducted over 42 days of culture. The larvae were fed three times per day, and the feed amount was increased regularly in accordance with larval growth. The results showed that the effects of both spirulina-based microcapsule diets on absolute growth rate (AGR), specific growth rate (SGR), and average daily growth rate (ADGR) of Chanos chanos larvae were comparable to those fed a commercial diet. The survival rates were 80.6 ± 11.17% for larvae fed Spirulina platensis with a gelatin and fish oil wall, 84.6 ± 8.44% for those fed Spirulina platensis with a gelatin, fish oil, and whole egg wall, and 83.8 ± 16.50% for those fed the commercial diet. This study demonstrated that spirulina-based microcapsules had similar effects to commercial feed on the growth of milkfish larvae, indicating that this diet could potentially replace commercial feed.
