The use of Silkworm (Anaphe infracta) pupae as a protein source was investigated for its ability to replace fishmeal in the diet of Clarias gariepinus, African cat fish. Five dried diets formulated at 40% crude protein were fed to fingerlings of an average initial weight of 14.33g at 0 (control diet), 25, 50, 75 and 100% inclusion levels of silk worm meal. The experiment was conducted for 84 days were measured. Mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR). The five inclusion levels of silk worm pupae supported the growth of Clarias gariepinus fingerlings, the growth and feed utilization were favoured by high inclusion level of silk worm meal. Significant differences (p<0.05) were observed among the treatments, although there were no significant differences (p>0.05) in the growth parameters between 50% and 75% inclusion levels. The 100% silk worm pupae meal inclusion gave the best final mean weight gain of 10.29g specific growth rate of 0.93%, feed conversion ratio of 2.18 and protein efficiency ratio (PER) of 0.012. The carcass protein and lipid contents increased compared to the levels of both at the beginning of the experiment. Even though, there were no significant differences (p>0.05) among proximate composition of the fish groups fed 25, 50 and 75%. The results showed that diet consists of 100% silk worm meal could be used as a complete replacement for fish meal in the diet formulation for Clarias gariepinus fingerlings.

Aquaculture offers the opportunity for safeguarding local and global food security in the face of declining capture fisheries. However, the form of aquaculture that is commonly practiced in Kenya is characterized by the use of agrochemicals such as fertilizers that negatively impact biodiversity especially when effluents from fish ponds drain into water bodies. This study aimed to determine differences in the growth rate of Clarias gariepinus, an important aquaculture fish in Kenya, to assess plankton diversity, and to identify phytoplankton species associated with pollution under organic and inorganic fertilization regimens using chicken manure, Diammonium phosphate, and urea, respectively. Average growth rate calculated per day was higher in the organically-fertilized ponds at 0.06 cm/day, followed by inorganically-fertilized ponds at 0.05cm/day and then, the control at 0.04 cm/day. Average weight gain was higher in organically-fertilized ponds at 0.08 g/day followed by ponds fertilized with inorganic fertilizer at 0.07 g/day and the control, at 0.06g/day. There were significant differences in growth rate across fertilization regimens (length: F2, 264= 24.06, p = 0.0399; weight: F2, 264 = 20.89, p = 0. 0457). Specifically, although differences in growth rate of fish in organically and inorganically fertilized ponds were not significant, fish in fertilized ponds were on average, longer and weighed more than those in the control pond. Jaccard’s similarity index for phytoplankton was highest (0.38) between organically-fertilized ponds and control but lowest (0.25) between inorganically-fertilized ponds and control. Use of chicken manure produced the highest diversity of zooplankton (Shannon-Weiner’s H in organically-fertilized pond = 1.886; inorganic = 1.044, and control = 0.935). The use of DAP and urea produced the highest proportion of phytoplankton species associated with pollution. These results do not support the commonly reported notion that ponds fertilized using inorganic fertilizers are more productive. Findings suggest that the use of inorganic fertilizers may threaten biodiversity in aquatic ecosystems through the production of toxic algae.

The biofloc technology can control water quality under negligible water exchange. The aim of this study was to evaluate the  effects of stocking density on production and blood performance of catfish (Clarias gariepinus [Burchell, 1822]). The catfish were reared in biofloc system (heterotrophic bacteria and addition of sugar for a period of 10 wk and used three levels of density i.e. (500, 1 000, and 1 500) fish per m2. The production increased with the increasing of stocking density, relative growth rate decreased with the increasing of that. The stocking density of 1 500 fish per m2 on the biofloc technology can support maximum catfish production, health and proper water quality.

Pengembangan budidaya ikan lele, Clarias gariepinus sering terjadi kendala dengan biaya pakan yang terlalu tinggi (60-70% dari biaya produksi). Barangkali, penggunaan bahan baku lokal seperti pemanfaatan tepung telur ayam yang nilai nutrisinya tinggi, mudah didapat, dan murah harganya merupakan salah satu solusinya. Tujuan penelitian ini adalah untuk mengkaji dan mengetahui pengaruh penambahan tepung telur ayam afkir dalam pakan buatan yang berprobiotik terhadap efisiensi pemanfaatan pakan, pertumbuhan dan kelulushidupan ikan lele dumbo (C. gariepinus). Penelitian ini menggunakan metode eksperimental dengan rancangan acak lengkap (RAL) yang menggunakan  4 perlakuan dan masing-masing 3 kali kali ulangan. Perlakuan itu adalah pakan yang tanpa menggunakan tepung telur ayam afkir (Perlakuan A), pakan yang menggunakan tepung telur afkir masing-masing sebanyak 15%, 30%, dan 45% sebagai Perlakuan B, C, dan D. Ikan uji  bibit lele dumbo (C. gariepinus) yang ditebar mempunyai bobot rerata 2.04±0.05 g dengan kepadatan 1 ekor/L yang dipelihara selama 42 hari. Variabel data yang diukur meliputi Tingkat Konsumsi Pakan (TKP), Efisiensi Pemanfaatan Pakan (EPP), Feed Convertion Ratio (FCR), Protein Efficiency Ratio (PER), Relative Growth Rate (RGR), dan Survival Rate (SR). Hasil penelitian ditunjukkan bahwa penggunaan tepung telur ayam afkir pada pakan buatan memberikan pengaruh yang nyata (p < 0.05) terhadap TKP, EPP, FCR, PER, dan RGR, tetapi tidak berpengaruh nyata (P≥0,05) terhadap SR. Perlakuan dengan penambahan tepung telur ayam afkir sebanyak 30% (Perlakuan C) memberikan nilai terbaik untuik TKP sebesar 146,87%, EPP sebesar 88,77%, PER sebesar 2,61% dan RGR sebesar 7,65%/hari dari perlakuan lainnya. Monitoring nilai kualitas air pada media pemeliharaan telah menunjukkan bahwa pada kisaran yang layak untuk pemeliharaan ikan uji. Catfish cultivation development, Clarias gariepinus often occur constraints with the high cost of feed  (60-70% of the production cost). Perhaps, the use of local raw materials such as the utilization of rejected chicken egg with high nutritional value, easy to obtain, and cheap price is one of the solution. The purpose of this research was to know the effect of addition of rejected chicken egg  powder inprobiotized artificial feed on the efficiency of feed utilization, growth and survival rate of catfish, C. gariepinus. This study was used an experimental method with completely randomized design (RAL) by using 4 treatments and each of them 3 replications. The treatments were feed without use of rejected chicken egg powder  (Treatment A), feed using 15%, 30%, and 45% of powder  meals of rejected chicken egg  as treatment B, C, and D, respectively. Catfish, C. gariepinus seeds were stocked with a mean weight of 2.04 ± 0.05 g with a density of 1 tail / L and cultured  for 42 days. The data variables measured were  Total of Feed Consumption (TFC), Feed Utilization Efficiency (FUE), Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER), Relative Growth Rate (RGR), and Survival Rate (SR). The results showed that the use of chicken egg starch in artificial feed gave a real effect (p <0.05) on TFC, FUE, FCR, PER, and RGR, but no significant effect (P≥0,05) on SR. Treatment with the addition of 30% chicken meal (Treatment C) had the best value for TFC at 146.87%, the FUE of 88.77%, the PER of 2.61%  and the RGR of 7.65% / day than of the another treatments. Monitoring of  water quality values on maintenance media has shown that at a reasonable range for the maintenance of catfish culture.

Monoculture is the rearing of single species of fish in a pond while polyculture is the farming of two or more species in the same physical space. This study aims to compare the growth parameters of Clarias gariepinus fingerlings in monoculture and polyculture, using concrete and earthen ponds in a randomized complete block design. The polyculture, comprised of Clarias gariepinus and Oreochromis niloticus. 480 fingerlings were used; the stocking density was 40fish in a 3x2x1.5m depth with initial weight (4.84±0.11547) for C. gariepinus in monoculture and 40 each in polyculture with an initial pooled weight of O. niloticus (50g) replicated thrice, it was fed for eight weeks with commercial feed (40% crude protein). Weekly, random sampling was done to measure the growth and adjust the feeding rate. The results revealed that polyculture has the best mean final weight (160.07±0.18559g) and weight gain of 155.29, while the highest total length (45.666±3.179) was recorded in monoculture for Clarias gariepinus reared in an earthen pond. The polyculture had the highest specific growth rate (2.46), Relative growth rate (246.49), and condition factor (0.184). There was a significant difference (P<0.05) in monoculture of both concrete and earthen ponds.
