One of the main problems facing aquaculture is the lack and high price of fishmeal and fish oil supply. The continued growth of aquaculture production cannot depend on these finite fisheries resources. It is imperative that inexpensive and readily available alternatives that do not compromise fish growth and product quality are found. It is in this specific context that this study consisting of a test of the Balanites aegyptiaca seed oil incorporated in the feed of Clarias anguillaris fries was conducted.The experiment lasted eight (8) weeks and included five treatments of two tanks each. This corresponds to a total of 10 tanks for 150 fries with a stocking density of 15 fish per tank. Five diets supplemented with 0% (R.0), 1% (R.1), 2% (R.2), 3% (R.3) and 4% (R.4) of the lipid source were administered twice daily for eight weeks. Growth was regularly monitored and mortalities recorded to assess the effects of each diet. The results revealed significant effects on growth performance and survival of Clarias anguillaris fries. For the average weight gain and the specific growth rate, the best result was obtained with the fish fed with diet containing 2% Balanites aegyptiaca seed oil (R.2). The best feed conversion ratio was recorded with the diet incorporating 2% of this oil. The best survival rates (66.67% and 70%) were observed in fries fed with diets incorporating respectively 2% and 3% of the oil. The experimental study has shown that a 2% incorporation rate is the most appropriate for the successful rearing of Clarias anguillaris fries.

To investigate the effects of replacement of fish oil by a mixture of Balanites aegyptiaca and Adansonia digitata seed oils three isonitrogenous (35.36%) and isoenergetic diets (3.48 MJ / kg) were formulated for one kilogram (1kg). The study was carried out on fries Clarias anguillaris for six weeks.At the beginning of the experiment, 90 Clarias anguillaris of the initial average weight of 0.82 ± 0.055g were randomly divided into three different groups with two replicates containing 15 fish/each. Fish were kept in six plastic tanks (50 x 40 x 30 cm) container (50 L). The results showed that the substitution of fish oil by a mixture of Balanites aegyptiaca seed oil and Adansonia digitata seed oil gives growth for all diets. However, the best growths are obtained from all points of view (MWGr, MWGa and SGR) with diet A (mixture of Adansonia seed oil and Balanites seed oil at a ratio of 20 : 20) followed by the diet D (mixture of Adansonia seed oil and Balanites seed oil at 10 : 30) compare to the control diet M containing fish oil. The best FCR was observed with the diet A followed by the diet D compare to the FCR observed with the diet M. The PER was higher in diet A (0.57) followed by diet D with (0.45) that has no significant difference with the control diet M (0.43). The highest value 63% was obtained with the diet D followed by 60% with the diet M and finally the lowest value 53% was obtained with the diet A. In regards to the growth performance, fish fed a 100% vegetable oil diet showed the best growth performance. Therefore, the replacement of fish oil with a mixture of Balanites aegyptiaca seed oil and Adansonia digitata seed oil has no negative impact on the growth of Clarias anguillaris fry. It would be interesting first to study the inclusion rate of Balanites aegyptiaca seed oil for a partial replacement of fish oil.

Although recirculation is a cultivation system that has been tried in various commodities, but the effectiveness of this system to the growth and survival of catfish juvenile has not been done. This study aims to determine the effective-ness of recirculation system on growth performance and survival rate of catfish juvenile (Pangasianodon hypophthal-mus). The research was conducted from 11 October to 30 November 2019 at hatchery unit Department of Fisheries Extension, Jakarta Technical University of Fisheries. This study used experimental method with 3 treatments, namely Control (K: 100% Bioball + Bacillus sp.), Treatment 1 (P1: 50% Bioball + 25% zeolite + 25% resin + Bacillus sp.) and Treatment 2 (P2: Bioball 25 % + zeolit 50% + resin 25% + Bacteria Bacillus sp.). The catfish used in this study was measured 0.08 + 0.02 g. Ind.-1. The fish were kept in a concrete tub of 100 cm x 150 cm x 70 cm with water volume of 750 liters tub-1. Stocking density of fish was 5 fish liters-1. Fish juveniles were fed with commercial feed with a dose of 3% of fish biomass with frequency of 3 times a day-1. Observation fish growth and water sampling for monitoring of the abundance of nitrogen-decomposing bacteria and water quality were carried out every 15 days. The results showed that the highest growth weight of catfish seedlings was found in treatment P1 (0.447±0.142b) compared with K (0.377±0.047a) and P2 (0.363±0.057a) treatment. The values of survival rate for K, P1 and P2 treatments were 51±8, 54±4 and 52±8, respectively. This result implies that no significant difference in the survival rates in all treatments.

A total of Two hundred and fifty (250), 1-day old (Cobb) broiler chicks with mixed sex were used to evaluate the the growth performance, caeca microbial population and immune response of starter broiler chicks fed aqueous extract of Balanites aegyptiaca and Alchornea cordifolia stem bark mixture (BACM). Birds were reared on a deep litter system and randomly divided into five treatment with five replicates consisting of 10 birds each in a completely randomized design. Treatment 1 (T1) were given basal diet + 0 % BACM, T2, T3, T4 and T5 were fed 20, 40, 60 and 80 ml/liter BACM respectively. The experiment lasted for 28 during which clean feed and water were offered ad libitum. The results obtained revealed that the average weight gain (AWG), feed conversion ratio (FCR) and mortality were influenced by the dietary treatments (P<0.05). Birds in T5 had the highest AWG and FCR (1159.3 g, 1.57) followed by T4 (1070.2 g, 1.70), T3 (1047.4 g, 1.74), T2 (981.1 g, 1.86) and T1 (850.7 g, 2.14) respectively. Activities of superoxide dismutase (SDA), glutathione peroxidase (GPx), catalase (CAT) ,malonyldialdehyde (MLA) and antibody titres against Newcastle and gumboro disease were significantly affected by BACM (P<0.05). Caeca microbial population of Escherichia coli and Lactobacilli were significantly different among the treatments (P<0.05). E. coli count in T1 were higher compared to other treatments (P<0.05), Lactobacilli population increased in T2, T3, T4 and T5 compared to T1. It was concluded that BACM can be fed to broiler chicks at 80 ml/litre without any negetive effect on the performance and immune response of birds.

Modern commercial pig production is a complex process that requires successful producers to understand and resolve factors associated with perturbations in production. One important perturbation is inventory loss due to mortality. In this study, data on 60 lots of approximately 2000 weaned pigs (n = 115,213) from one commercial production system were collected through the wean-to-finish (WTF) cycle with the objective of establishing patterns of mortality, estimating differences in profit/loss among patterns of mortality, and identifying production practices associated with mortality patterns. Information provided by the production system included the number of pigs in each lot at the time of placement (beginning inventory), weaning weight, barn dimensions, number of dead pigs (NDP) daily, capacity placed (proportion pigs actually placed versus what had been planned to be placed) and average weight sold. Analysis of NDP revealed three mortality patterns (clusters I, II, III) composed of 6, 40, and 14 lots, respectively, that differed in the temporal onset and/or level of mortality. Average daily gain (ADG) and feed conversion ratio (FCR) were calculated by growth phase for each cluster. An economic model showed profit differences among clusters due to poor biological performance by clusters I and III in the late finishing phase. Cluster II (n = 40) had fewer dead pigs and the highest profit compared to clusters I (n = 6) and III (n = 14). Area per pig (stocking density) was the only factor associated with the differences in mortality patterns. Routine monitoring and the analysis of mortality patterns for associations with production and management factors can help swine producers improve biological performance and improve profit.

The response of Clarias gariepinus to Allium sativum on growth performance and as anti-bacterial agent in Staphylococcus aureus challenge infection was evaluated. A. sativum was included at 0% (control), 1.5%, 3.0%, and 4.5% in fish diet. Twenty fish samples each were randomly distributed into four tanks (T1, T2, T3 and T4). Fish were fed twice daily at 5% body weight for twelve weeks. All fish were challenged with 0.5ml of pure culture of S. aureus. A significant (P<0.05) increase in body weight, total length and standard length was observed. A. sativum at 3.0% inclusion promoted highest growth with feed conversion ratio (1.25-1.41), protein efficiency ratio (1.72-0.56), specific growth rate (1.92-2.09), condition factor (0.83-1.99) and survival rate (60-95). Fish-fed A. sativum diet showed that 4.5% inclusion had the least S. aureus activity. Bacteria load significantly (P<0.05) decrease at week 12. Culture water had dissolved oxygen of 4.0 - 4.2 mg/L, pH 6.0 - 7.0 and temperature of 26.0-28.0oC. This study has shown that A. sativum supplemented diets enhanced growth of C. gariepinus and functioned as antibacterial agent against S. aureus. A. sativum at 3.0% inclusion in diet is recommended for better fish growth and 4.5% A. sativum for antibacterial action. Keywords: Fish, herb, growth, infection

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

Clarias anguillaris fries were fed with three isoproteic (30.25%) and isoenergetic (1.42 MJ/Kg) diets to evaluate the effects of plant seed oil on the growth performance, feed efficiency and survival rate. The test was carried out on Clarias anguillaris with an initial average weight of 0.07 g distributed in 6 plastic tanks with a stocking density of 15 fries each. The treatments were in duplicate for 45 days. The results of this experiment showed that the fish fed diet B containing Adansonia digitata seed oil as a source of lipid has the best total average weight gain (AWGa) (0.15g) compared to those fed with P and S diets containing fish oil and the Balanites aegyptiaca seed oil respectively. Similar results were obtained with the specific growth rate, which showed a significant difference between the fish fed with B diet and those fed with S and P diets that do not differ significantly between them. The best feed conversion rate (FCR) was obtained with the fish fed with B diet, which showed a significant difference with the fish fed with P and S. The best survival rate (SR) of 80% was obtained with the fish fed with diet B, followed by 73% in fish fed with diet S, and finally the lowest value 67% was contained in the fish fed with the control diet P. The best protein efficiency ratio (PER) was obtained with the fish fed with diet B (1.16) followed by the fish fed with diet S (0.80) compared with the fish fed with the control diet P (0.74). From the results of this study, we can say the replacement of fish oil with Balanites aegyptiaca seed oil and Adansonia digitata seed oil has no negative impact on the growth of Clarias anguillaris fries. In conclusion, diet B containing Adansonia digitata seed oil appears to be more suitable for Clarias anguillaris fry growth.

The effect of stocking density on growth performance and survival rate of endangered Labeo bata, was conducted in nursery ponds from 14th June to 13th August, 2013. Three different stocking densities viz. 500, 600 and 700 piece-1 decimal were assigned as treatment T1, T2 and T3, respectively. The initial average weight of L. bata was 0.15±008 g. Hatchlings in all the nursery ponds were fed indigenous feed (26.95% crude protein) for 8 weeks. Temperature, ammonia nitrogen, pH had no significant differences (P<0.05). Final weight (g) was found to be the highest (4.06±0.06) in T1 and the lowest (3.20±0.03) in T3. The mean values of weight gain (g) was the highest (3.91±0.06) in T1 and the lowest (3.05±0.03) in T3. SGR was highest (5.49±0.02) in T1 and lowest (5.09±0.02) in T3. Yet again, survival rate was highest (70.33±0.88) in T1 where stocking density was the lowest among those aforementioned three treatments and lowest (61.00±0.58) in T3 where the stocking density was the highest among the treatments. And finally production (kg-1ha) was found highest (352.66±4.42) in T1 and lowest (337.50±3.19) in T3. Rearing of the Labeo bata fry in those three different stocking densities showed significant (p<0.05) variation both in highest survival and growth performance. Overall production of L. bata in treatment T1 was significantly higher than that of the other two treatments T2 and T3. Despite of this, consistently higher CBR was found from treatments T1 (1:1.78) than from treatment T2 (1:1.25) and T3 (1:1.06).J. Environ. Sci. & Natural Resources, 9(1): 67-73 2016
