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.

A strain comparison experiments was carried out in wild Clarias gariepinus with the aim of evaluating the reproductive performance, (in terms of percentage fertility and hatchability) growth and survival for choice of strain in selective breeding. Live samples of wild C. gariepinus collected from River Argungu, Kebbi state (KB) and Eleyele dam, Oyo state (OY), Nigeria were crossbred and mated in pure parental and reciprocal crosses generating four mating combinations (generic crosses) replicated three times in completely randomized design (CRD) manner. The F1 generations were reared indoor for 56 days. The hybrids revealed higher characters compared to the progeny of pure parental groups in fertilization rate (84.000±0.270%; 78.265±0.135% compared to 88.400±0.130%; 71.465±0.265%), hatching (77.305±0.405%;72.235±0.465% compared to 80.995±0.025%; 64.555±0.615%) and survival of larvae (100.000±0.000%; 98.582±1.418% compared to 98.840±0.581%; 73.371±0.157%). On the other hand, fertilization and hatching rate among the hybrids and the pure crosses were statistically significant (P<0.05). Similarly, significant difference (P<0.05) was observed between the two reciprocal hybrids. However, the hybrid crosses showed intermediate characters between the pure crosses in mean weight gain (MWG), specific growth rate (SGR) and survival of fingerlings. Though the crosses of pure Oyo species displayed significantly higher value in MWG (5.583±0.058g) and SGR (10.319±0.051g) than other groups, fingerling survival (73.371±0.157%) was found to be lowest. The growth parameters like MWG (4.884±0.001g) and SGR (10.231±0.130g) of the hybrids of Oyo fingerlings were found to be higher than pure Kebbi crosses, while survival (100.000±0.000%) of hybrid of Kebbi fingerlings were higher than pure Kebbi (98.840±0.581%). Therefore, this is considered as heterosis (hybrid vigour) for the hybrids they have achieved better traits either one of the pure groups. Intra-specific cross of female wild C. gariepinus from Kebbi and male wild C. gariepinus from Oyo (KB♀ × OY♂) be practiced for optimum performance used in commercial production. This will ensure high fertility, hatchability, growth and survival rate. Key words: Clarias gariepinus, growth, reproductive performance, Strain comparison, survival.

The no-till system has been growing over the years and for this system to be successful, it is essential to maintain permanent vegetation cover over the soil, an adequate crop rotation system with minimal overturning. A strategy for soil protection is to introduce species of cover crops in winter under single or intercropping. The objective was to evaluate the rate of soil cover by intercropping between black oats (Avena strigosa L.) and forage turnip (Raphanus sativus L.) at different sowing densities, as well as the isolated species in terms of soil protection under no-tillage. The study was conducted at the Federal Technological University of Paraná (UTFPR), campus Santa Helena, with a randomized block design, with five treatments and three repetitions. The treatments were: 100% black oats (BO); 100% forage turnip (FT); 75% BO + 25% FT; 50% BO + 50% FT and 25% BO + 75% FT. The cover crops were sown in May 2019. The percentage of soil cover from 21 to 91 days after sowing (DAS) was evaluated using the photographic method, with weekly collection of images in an area delimited by a metallic frame (25 m²), positioned on the ground at two fixed points per plot. The coverage rate quantification was estimated by overlaying a grid with 100 points of intersection over each image. The rate of soil cover by consortia and single crops did not show a statistically significant difference. To 49 days, consortia had coverage equal to or greater than 70%, while for single species, this percentage was reached at 56 DAS and 70 DAS, for BO and FT, respectively. All treatments showed high potential for soil protection and coverage rate from 70 DAS.

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.
