Growth Performance of Catfish (Clarias gariepenus) Cultured of High Density with Biofloc System

ABSTRACT This study was aimed to analyze the growth performance of African catfish Clarias gariepinus cultured in the biofloc system at high stocking density. African catfish with an average weight of 1.85±0.09 g were cultured in four units of tarpaulin tank at a diameter of 1.72 m and a height of 1.05 m with a volume of ±2,000 L at the different density of 1,000 fish/m3; 1,500 fish/m3; 2,000 fish/m3; 2,500 fish/m3. During rearing period, fish were given the artificial feed with protein contents of 28.75% with the frequency of twice a day, as much as 3% of the body weight. The results showed that different treatment of high stocking density in the biofloc system had a significant effect on the absolute growth rate, lipid retention and energy retention (P<0.05) but not significant effect on daily growth rate. The results showed that the highest lipid retention and energy retention were found in the group of fish treated at a stocking density of 2,500 fish/m3 but declining protein retention and growth in fish occurred. The highest absolute growth rate and daily growth rate were shown by treatment with a stocking density of 1,500 fish/m3. Keywords: growth, stocking density, biofloc ABSTRAK Penelitian ini bertujuan untuk menganalisis performa pertumbuhan ikan lele dumbo Clarias gariepinus yang dipelihara pada sistem bioflok dengan padat penebaran tinggi. Ikan uji memiliki berat rata-rata 1,85±0,09 g yang dipelihara pada kolam terpolin berdiameter 1,72 m dan tinggi 1,05 m dengan volume air ±2.000 L sebanyak empat unit dengan kepadatan yang berbeda yaitu 1.000 ekor/m3, 1.500 ekor/m3, 2.000 ekor/m3, 2.500 ekor/m3. Selama 40 hari masa pemeliharaan, ikan diberi pakan buatan berkadar protein 28,75% dengan frekwensi dua kali sehari, sebanyak 3% dari berat tubuh. Hasil penelitian menunjukkan bahwa perlakuan perbedaan padat penebaran tinggi pada sistem bioflok memberikan pengaruh yang nyata terhadap pertumbuhan mutlak, retensi lemak dan retensi energi (P<0,05) namun tidak memberikan pengaruh nyata terhadap laju pertmbuhan harian. Hasil penelitian menunjukkan bahwa semakin tinggi padat penebaran terjadinya peningkatan retensi lemak dan retensi energi yaitu pada perlakuan padat penebaran 2.500 ekor/m3 tetapi terjadi penurunan nilai retensi protein dan pertumbuhan pada ikan. Nilai pertumbuhan mutlak tertinggi ditunjukkan oleh perlakuan dengan padat penebaran 1.500 ekor/m3. Kata kunci: pertumbuhan, padat tebar, bioflok

Lettuce (Lactuca sativa L.) and African catfish (Clarias gariepinus) were preferred to grow in aquaponics due to their high and fast productivity growth. However, limited research was conducted on the impact on different inorganic substrates’ growth performance in aquaponics. In this study, lettuce’s growth performance was determined in four different kinds of inorganic substrates in Nutrient Film Technique (NFT) aquaponics by measuring final weight, daily growth rate, stem diameter, plant and root lengths, leaf number per plant and shoot/root ratio. Polyester fiber, rock wool, zeolite, and gravel were used as inorganic substrate materials. A constant flow rate of 0.3 L/min was maintained using with a submersible pump motor. At the end of the study, the African catfish’s feed conversion ratio was estimated to be 0.66, while the specific growth rate (SGR) was 2.3%. Total lettuce yields for polyester fiber, rock wool, zeolite and gravel were obtained as 5.072,22 kg/m2, 4.934,03 kg/m2, 6.067 kg/m2, and 5.382,64 kg/m2 respectively. There were statistically significant differences for daily growth rate between the inorganic substrates that the significantly highest values were recorded in the zeolite. The results revealed that initial plant length and shoot/root ratio were the significant factors on the growth performance for lettuce in aquaponic system tested. The best lettuce yield performance was observed in zeolite substrate but, economically available option was found as gravel for hydroponic troughs.

Lemna Perpusilla

Currently, the use of unconventional food sources in the inclusion of fish diets is cause of great interest. The growth performance of African catfish (Clarias gariepinus) was evaluated, with the inclusion of duckweed meal (Lemna perpusilla) in four levels (0, 6, 12 and 18 %) in the diet. African catfish with an average weight of 1.27 ± 0.03 g, were distributed in a completely randomized design, with 16 experimental cages (four replicates/treatment). The fingerlings were fed for 48 days of experimentation. An analysis of variance and a Duncan´s test were performed. No significant differences were found (p< 0.05) for the first two levels evaluated, but with the rest there were differences, as the percentage of inclusion of the duckweed meal in the ration increased. Final weight was decreasing, as well as absolute growth rate, increase in daily weight, feed conversion ratio and food efficiency. Survival throughout the experiment was between 72 y 65 % in all treatments. The inclusion of duckweed meal in the diet did not affect the parameters of water quality. It was concluded that the L. perpusillase meal can be included up to 12 % in diets for African catfish fingerlings, without affecting the growth performance.

The experiment was designed to evaluate the effect of egg size on hatching quality and post-hatch growth performance of normal feathered indigenous chickens. Hatchable eggs, grouped into three sizes: medium/control, small and large, were incubated to obtain day-old chicks. One hundred and eighty (180) day-old chicks were allotted to three treatment groups according to the egg sizes from which they were hatched. Egg size significantly (p<0.05) influenced chick hatching weight. Chicks hatched from large eggs were the heaviest (36.89g) while those obtained from small ones were the smallest (31.02g). Daily growth rate (DGR) was progressive and uniform in both cockerels and pullets in the first 8 weeks of life across the treatment groups. It was concluded that egg size, though could determine chick hatching weight, but not a good predictor of post-hatch growth performance in normal feathered indigenous chickens

Mudcrab fattening is potential to develop in mangrove areas. The aim of the present study was to determine the best ratio of male and female in fattening of mud crab in the mangrove area. Research was conducted in the mangrove areas of Pangkep Regency, South Sulawesi Province. Test animals used were mud crab S. olivacea male and female measuring weight of 250 ± 10 g and were stocked at a density of 10 animals/cage. The bamboo cages measuring length, width, and height of 1.0 x 1.0 x 1.0 m3 were placed in the mangrove areas. Feed used was trash fish at 10% of the biomass with the feeding frequency of two times a day ie morning (30%) and afternoon (70%). The study used a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The ratio of male and female crabs were 7:3; 6:4; 5:5; 4:6 and 3:7 crabs/cage, respectively. Results of analysis of variance showed that the treatment with the different ratio of male and female was not significant (p> 0.05) on the survival rate of crab, but was highly significant (p <0.01) on the absolute and daily growth rate. The resulting survival rate ranges from 93.33 to 100%, absolute growth and the highest daily growth rate of crabs produced at a ratio of males and females (7:3) and (6:4) crabs/cage ie: 56.99 and 1.35; 56.25 g and 1.36%/day, while the lowest was in the ratio (3:7) crabs/cage ie: 28.97 g and 0.73%/day.

African catfish (Clarias gariepinus) is one type of freshwater fish that has high economic value. African catfish with intensive cultivation are hampered by the high cost of feed that is not in accordance with the selling price of African catfish. An alternative effort that can be done is the addition of probiotics to feed which is expected to reduce feed costs. Probiotics are living microorganisms in fish culture that can prevent disease, thereby increasing production and can reduce economic losses. This study aims to analyze the effect of probiotics on the growth of absolute weight and daily growth rate of African catfish. The method used was Completely Randomized Design (RAL) with 4 treatments namely 0, 2, 4 and 6 ml / kg of feed and repeated 3 times. Activities carried out in this study include preparation of containers, seed stocking, fish sampling, feed preparation, feeding and water management. The variables observed were absolute weight growth and daily growth rate. The results showed that the addition of probiotics to commercial feed significantly affected the growth of weight and daily growth rate of African catfish

Calcium Effect

Pertumbuhan udang galah dibatasi oleh kulitnya yang bersifat tidak elastis, karena terdiri atas khitin. Agar udang galah tumbuh dengan baik, maka harus ada unsur mineral dalam pakannya. Salah satu mineral yang bersifat esensial adalah mineral kalsium. Kalsium mempunyai fungsi dalam pembentukan tulang, jaringan lunak, proses regulasi dalam tubuh, dan menjaga keseimbangan asam basa. Oleh karena peran penting dari kalsium tersebut, maka dilakukan penelitian mengenai efek mineral kalsium dalam ransum pakan udang galah terhadap pertumbuhannya. Hewan uji yang digunakan pada penelitian ini adalah yuwana udang galah dengan kisaran bobot 56,0 ± 3,0 mg. Rancangan penelitian menggunakan Rancangan Acak Lengkap dengan perlakuan yang diterapkan adalah kalsium 1,0%; 3,0%; 5,0%; 7,0%; dan 0,0% sebagai kontrol. Setiap perlakuan mendapat 3 ulangan. Hasil penelitian ini menunjukkan bahwa kadar kalsium dalam ransum pakan sangat mempengaruhi laju pertumbuhan harian udang galah (P<0,05). Kadar kalsium yang optimal dalam ransum pakan udang galah adalah sebesar 3,46%.The growth of giant prawn is limited by a non elastic material called chitin, which is a limiting factor in its growth. Feed containing mineral is needed to improve its growth. One of the essential minerals is calcium. The function of calcium is essential in bone and soft tissue formations, acid balancing, and regulation processes in the body. Because of its benefits, the research on the calcium effect on giant prawn was conducted. The aims of this study was to know the effect of calcium on the growth rate of giant prawn juvenile. Test animals were juveniles of giant prawn with average weight of 56.0 ± 3.0 mg. Research design employed complete randomized design with five calcium mineral treatments as follows:1.0%, 3.0%, 5.0%, 7.0%, and 0.0% as control. Each treatment has three replications. The result showed that calcium affected the daily growth rate of giant prawn (P<0.05). The calcium dosage of 3.46% is the optimum level for giant prawn juvenile.
