Abstract African catfish (Clarias gariepinus) is one of fish consumption use to fulfill animal protein. The fulfillment need of animal protein with aquaculture effort, where as in the aquaculture effort will larvae quality increased. Increasingly of larvae quality with natural food had been adding feed supplement. Natural food to used is Daphnia spp. and then food supplement to used is viterna. The viterna will increase Daphnia nutritions, because of the viterna contains many nutritions to survival and growth of African catfish. The aim of this study was to know the influence of Daphnia spp. enrichment with viterna to survival and growth of African catfish (Clarias gariepinus) larvae. The rearing of larvae during 40 days. This study used Complete Random Design. The treatment were A (present Daphnia spp. without viterna), B (Daphnia spp. enrichment with viterna 10 ml/L dose), C (Daphnia spp. enrichment with viterna 10 ml/L dose), D (Daphnia spp. enrichment with viterna 10 ml/L dose), E (Daphnia spp. enrichment with viterna 10 ml/L dose) dan F (Daphnia spp. enrichment with viterna 10 ml/L dose), each treatment with 4 replications. The result show that viterna applications to Daphnia was significantly influenced (p<0,05) to survival African catfish larvae. The highest survival was E treatment (7,25 %). The viterna leaf to Daphnia spp. Was significantly influenced (p<0,05) to specific growth rate African catfish larvae. The highest specific growth rate was B treatment (1,885 %BW/day).

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.

An experiment was designed and carried out to assess the growth performance and feed utilization (weight gain, feed conversion ratio, protein efficiency ratio, specific growth rate, feed intake and survival) of Clarias gariepinus fingerlings fed graded levels of toasted Leucaena leucocephala seed meal based diets with the aim of establishing the best inclusion level of Leucaena seed meal. One hundred and eight (108) fingerlings with an initial mean weight of 2.10g were allotted at random to six treatments in triplicate groups with each treatment tank having six fingerlings and were fed with isocaloric and isonitrogenous diets containing 40% crude protein (CP). The toasted seed meal was used to replace soybean meal in the diets in the following proportions: diets I (0%), diets II (10%), diets III (20%), diets IV (30%), diets V (40%) and diets VI (50%). At the end of the feeding trials that lasted for 6 weeks, the mean weight gains of fish, relative weight gain, specific growth rate, feed intake, feed conversion ratio and protein efficiency was highest in treatment I while mean weight gain of fish, relative weight gain, specific growth rate and feed conversion ratio was lowest in treatment V. Feed intake was lowest in treatment VI and protein efficiency was lowest in treatment II. Survival among treatments slightly varied significantly but was not as a result of the feed consumed. At the end of the experiment, the recommended inclusion level of Leucaena seed meal was 20%.

The impact of water renewal in a static system on the growth and survival of Clarias gariepinus fingerlings was investigated under six different treatments, namely: T1 (daily water renewal), T3 (three days water renewal), T5 (five days water renewal), T7 (seven days water renewal), T9 (nine days water renewal) and T14 (fourteen days water renewal). Results showed that growth performance and survival was significantly (P< 0.05) affected by the water renewal frequencies. After six weeks, weight gain, daily weight gain, specific growth rate, final body weight, was significantly higher in T5 (P< 0.001). Likewise, survival in T5 was significantly higher compared to other groups (P< 0.001). For all evaluated parameters, T14 had the least performance. Slow response to feeding, slow movement and hanging on the water surface was observed in T9 and T14. Daily water renewal tank had significantly (p < 0.05) higher dissolved oxygen (04.52 mg L-1) while electrical conductivity (800.00 μScm-1) was significantly higher in T14 (P< 0.001). From the result, the growth and survival of the catfish fingerlings in T5 are superior to other renewal regimes. Therefore, for optimum growth and productivity of African catfish fingerlings reared in a static system, it is recommended that water renewal be performed every five days.

In intensive aquaculture farming activities will generate solid waste and liquid waste that comes from feces and leftover fish feed. The waste accumulation can lead to deterioration of water quality that affects the physiological processes, behavior, growth, and mortality of fish. Technological innovation is needed for the management of water quality and increase productivity as a result of shrinkage of cultivated land. One of the technological innovations that can be applied, namely the incorporation of fish farming with crops through Aquaponics system. This study aims to determine the effects of water spinach optimum density to absorb waste ammonia (NH3), nitrate (NO3) and nitrite (NO2) optimally to increase the survival rate and growth rate of african catfish (Clarias sp.) intensive As well as to see its effect on conversion rates and feed efficiency with aquaponics system. The method used is the experimental method. The experimental research is used to determine the effect of certain variable towards a group under controlled conditions. The results of measurements of ammonia levels during P0 showed that the treatment significantly different (p <0.05) with treatment P1; P2; and P3. P3 treatment with water spinach number 40 stems provide maximum results in lowering the concentration of ammonia compared with treatment P0 (without spinach), P1 (20 water spinach), and P2 (30 water spinach). The measurement results nitrite levels during the observation showed that all treatments there were no significant differences (p> 0.05). The measurement results also showed that the nitrate content whole of observation results showed that all treatments there were no significant differences (p> 0.05). The best feed conversion ratio was found in P3 treatment of 1.08. The best feed efficiency was found in P3 treatment 92,25%. The highest survival rate was found in P3 treatment (88.69%) in maintenance medium and lowest survival rate was in P0 treatment (26,71%) without water spinach  (control). The highest specific growth rate was found in P3 treatment (1.15%), while the lowest specific growth rate was in treatment P0 (0.79%).Results of water quality measurement supporting all treatments decreased and increased. The supporting water quality are temperature, pH, and dissolved oxygen. The decrease and increase in support water quality is caused by environmental factors such as weather. Other parameters were observed in addition to supporting the water quality is water spinach plant growth. Value growth water spinach is best found in treatment P3. In the treatment P3 water spinach growth rose 5.14 cm with an initial size of 10.92 into 16.06.

The objective of this study was to determine the antimicrobial effect of a combination of potassium lactate and sodium diacetate (0, 1.8, 3, and 4.5%; PURASAL P Opti.Form 4, 60% solution) on the survival and growth of Listeria monocytogenes Scott A in pH-adjusted broth (5.5, 6.0, 6.5, and 7.0) stored at 4, 10, 17, 24, 30, and 37°C. Appropriate dilutions of broth were enumerated by spiral plating on tryptose agar and counted with an automated colony counter. Growth data were iteratively fit, using nonlinear regression analysis to a three-phase linear model, using GraphPad PRISM. At pH 5.5, the combination of lactate-diacetate fully inhibited (P &lt; 0.001) the growth of L. monocytogenes at all four levels and six temperatures. At pH 6.0, addition of 1.8% lactate-diacetate reduced (P &lt; 0.001) the specific growth rate of L. monocytogenes and increased lag time; however, 3 and 4.5% completely inhibited the growth at the six temperatures studied. Efficacy of the lactate-diacetate mixture was decreased as pH increased and incubation temperature increased. Thus, at pH 6.5, at least 3% was required to retard (P &lt; 0.001) the growth of L. monocytogenes in broth. There was a limited effect of the lactate-diacetate level on the specific growth rate of the pathogen at pH 7.0. However, 1.8 and 3% significantly lengthened the lag time at 4 and 10°C. These results suggest that 1.8% of lactate-diacetate mixture can be used as a substantial hurdle to the growth of L. monocytogenes when refrigerated temperatures are maintained for products with pH less than 6.5.
