Upaya meningkatkan produktivitas lahan tambak dapat dilakukan dengan meningkatkan padat penebaran disertai dengan pemberian akuinput yang prima serta dukungan teknologi yang memadai. Tiga padat penebaran yaitu 750; 1.000; dan 1.250 ekor/m2, diaplikasikan pada tambak dengan luasan 1.000 m2 dengan kedalaman air 1,8 m dilengkapi dengan sistem aerasi berupa kincir dan root blower, pompa submersible, automatic feeder, central drain dan collector drain serta Instalasi Pengolah Air Limbah (IPAL). Kapasitas sistem aerasi adalah 500 kg biomassa udang/HP. Udang dipelihara selama 105 hari. Hasil penelitian menunjukkan bahwa padat penebaran yang diaplikasikan menghasilkan bobot akhir udang yang relatif sama berkisar 15,48-16,30 (15,78±0,45) g/ekor dengan nilai pertumbuhan harian 0,16-0,18 (0,17±0,01) g/hari. Produksi yang diperoleh adalah 7.862; 10.699; dan 12.163 kg/petak, masing-masing pada padat penebaran 750; 1.000 dan 1.250 ekor/m2. Nilai rasio konversi pakan 1,4; 1,36; 1,55 dan kebutuhan listrik 3,2; 2,5; 2,4 kw/kg udang serta kebutuhan air 2,24; 1,66; 1,60 m3/kg udang. Biaya produksi udang terendah adalah Rp. 30.526/ kg udang pada padat penebaran 1.000 ekor/m2 dengan laba operasional sebesar Rp. 630.687.094/th. Padat penebaran 1.000 ekor/m2 menghasilkan kinerja lebih baik sehingga disarankan menjadi acuan padat penebaran untuk budidaya udang vaname superintensif. Teknologi ini memiliki potensi dampak terhadap lingkungan perairan, sehingga perlu dilengkapi sarana Instalasi Pengolah Air Limbah (IPAL) untuk pengolah air buangan tambak.In order to increase of brackishwater pond’s productivity, an effort can be reached through high stocking density of shrimp accompanied by application of high quality inputs and supported by an appropriate technology. Three different stocking densities, were applied i.e., 750; 1,000; and 1,250 ind/m2. The shrimp were reared for 105 days in three ponds with sizing of 1,000 m2 each and the water depth of 1.8 m facilitated with aeration systems consisted of paddlewheels, root blower, submersible water pump, automatic feeder, central drainage, collector drainage and waste water treatment plan. The capacity aeration systems was 500 kg of shrimp biomass/HP. The results showed that all stocking densities produced the similar final body weight of shrimp which ranged between 15.48 to 16.30 (15.78±0.45) g/shrimp with daily growth rates were 0.16-0.18 (0.17±0.01) g/day. The total harvested shrimps from each stocking density were 7,862; 10,699, 12,163 kg/pond, respectively. The feed conversion ratio was 1.4, 1.36, and 1.55, whereas consumed electricities were 3.2, 2.5, and 2.4 kw/kg shrimp and water demands were 2.24, 1.66, and 1.60 m3/kg harvested shrimp. The lowest production cost was IDR 30,526/kg harvested shrimp which was spent for stocking density of 1,000 ind/m2, whereas the annual profit was IDR 630,687,094. The stocking density of 1,000 ind/m2 showed high performances, and then eventually is recommended for the L. vannamei super-intensive aquaculture. This technology is potential in affecting the adjacent environment, however the impacts might be minimized through the application of deploying wastewater treatment plan.

The efficiency of feed is considered as one of the most crucial factors that affects the growth performance, feed conversion ratio and yield as well. The study was aimed to compare the growth parameters of tilapia at different stocking densities to detect the efficiency of sinking feed assessing the growth trends at various sampling stages. To evaluate the comparative yield, the study was carried out in twelve concrete tanks under an outdoor laboratory shed. Tilapia (Oreochromis niloticus) fry was released at the rate of 8 fry per tank as per the recommended stocking density of 320 fishes/decimal and 4 fry per tank equivalent to the stocking density of 160 fishes/decimal in intensive and semi-intensive aquaculture system, respectively. To evaluate the growth trends sinking feed was used for feeding the fish during the experimental period for T1 (Intensive) and T2 (Semi-intensive), respectively. The feed was supplied in each with three replications at the rate of 20%, 15%, and 10% of the body weight of fish, respectively. The daily ration of feed was delivered to fish dividing into two parts daily. Aeration facilities using air stone aerator were installed for 24 hours. To assume the consecutive growth trends, weight of fish was recorded in 3 days interval to have better understanding on the yield performance in relation to the feed conversion ratio (FCR). Water quality parameters i.e., temperature and dissolved oxygen (DO) were recorded two times daily. The final weight gains of fish were 133.77±5.65 gm and 50.70±2.40 gm for T1 and T2, respectively. The mean percent weight gain of tilapia was higher in T1 (1127.25±0.00) than T2 (518.51±0.00 gm). Feed conversion ratio (FCR) in T1 and T2 were 1.97±0.11 and 1.70±0.07, respectively. The specific growth rates (SGR) of tilapia in T1 4.90±3.03 and 4.78±3.83 considering the data at the beginning and the end of the production cycle, respectively. Higher total production was obtained in T1 (1070.19 gm) than T2 (610.00 gm) with 100% survival in both the treatments. The present study reveals that, the efficiency of sinking feed was higher in T1 than T2 and farmers might be suggested to practice tank-based intensive aquaculture system to get higher production in a short period of time.

High production costs in grouper nursery can be caused by the use of large fingerlings size and long rearing times. The purposes of this study were to evaluate the culture performance and economic profitability of “cantang” hybrid grouper juveniles reared at different initial stocking sizes and nursery periods. This research lasted from September to December 2017 in one of small scale hatcheries in Buleleng, Bali, Indonesia. This study consisted of two experimental treatments; the first treatment was different initial stocking sizes (body weight and total length) of 0.50 ± 0.07 g and 3.0 ± 2.1 cm; 3.50 ± 0.67 g and 5.0 ± 1.9 cm; and 6.10 ± 0.91 g and 7.0 ± 2.3 cm. The second treatment was different nursery periods with the following arrangement: 15, 30, and 45 days (initial body weight and length of 0.54 ± 0.067 g and 3.0 ± 0.09 cm, respectively). The stocking density in all treatments was 1,000 fish reared in a 2 m x 2 m x 1 m concrete tank. The observed culture performance parameters consisted of survival rate (SR, %), daily growth rate (DGR, g/day), and feed conversion ratio (FCR). The calculated economic profitability parameters were net profit, return-on-investment (ROI, %), and return cost ratio (R/C). The highest culture performance was achieved by the juveniles reared using the largest initial stocking size and longest nursery period. This was in contrast with the economic profitability, in which smaller initial stocking size and middle nursery period had resulted in the highest profit. Based on the culture performance and profitability considerations, the suggested combination of initial stocking size and nursery period for cantang fingerlings is 3.0 ± 2.1 cm initial stocking size and 30 days rearing times.

The study was carried out to evaluate the effect of concrete feeding trough, semi-automatic feeder and their combination on growth performance of weaned pigs. Sixty weaned cross bred (Large white x Landrace) pigs of average initial weight of 9.04 Kg were grouped based on sex and assigned to three dietary treatments, comprising two replicates of 10 weaned pigs each. The design of the experiment was completely randomized design. A standard diet was prepared to meet the nutrient requirements of weaned pigs. The diet was fed to the animals in concrete feeding trough (T1), semi-automatic feeder and concrete feeding trough (T2) and semi-automatic feeder (T3). The experiment was partitioned into three periods (Weeks 1-4, 5-8 and 1-8). Feed and water were given unrestrictedly throughout the period of the experiment. The feed intake and weights of the pigs were recorded on weekly basis. Feed conversion ratio and daily weight gain were calculated and the study lasted for eight weeks. There was no significant (P>0.05) effect of feeders on final body weight, average daily weight gain, daily feed intake and feed conversion ratio. The overall performance showed that combination of the feeders (T2) improved daily weight gain (369.71 g), average daily feed intake (1021.14 g) and had the best feed conversion ratio (2.99). It could be concluded that combination of concrete feeding trough and semi-automatic feeders improved the growth performance of weaned pigs.

Red tilapia is a one of the economically important fish species. In order to increase growth and feed efficiency, feed restriction strategies can be carried out. This study aims to determine the effect of periodic (weekly) restriction of feed on compensatory growth and physiological responses of red tilapia during the enlargement phase. The activity was carried out at the Fish Breeding Research Center for 4 months. The research method used a completely randomized design (CRD) 4 treatments with 3 replications, namely control (fish were fed daily), 1 (1 fasting day a week), 2 (2 fasting days a week), and 3 (3 fasting days  a week). Fish rearing was conducted on the concrete tub measuring 2 x 1 x 0.8 m3 with a stocking density of 10 fish m-2. During the maintenance period of 120 days the fish were fed satiation twice a day. The results showed significant differences (P <0.05) in the value of weight growth, specific growth rate, daily growth and feed conversion ratio between control and other treatments, but not significantly different from treatment S1. The highest survival value was indicated by S1 treatment. The blood faal values of fish that were given feed restrictions consisting of red blood cells, white blood cells, hematocrit and hemoglobin showed that there was not significantly different than control fish (P> 0.05), which was at normal values. Restriction of feed to 1 day a week showed partial compensatory growth with better feed efficiency than fish fed daily.

Aim: To rear stunted Labeo rohita fingerlings in cages and determine the optimum stocking density and feeding ration for better growth performance of fishes. Methodology: Eight-month-old stunted fingerlings of Labeo rohita (14.65cm/38.23g) were stocked in floating net square cages at different stocking densities (10, 15, 20 and 25 fishm-2) and fed with different feeding ration (3%, 4%, 5% and 6% of body weight), further reared for 330 days and fed twice a day with commercial floating pellets with 25% crude protein. The study followed 4*4 factorial design and were triplicated for each treatment and level. Results: The study found a decrease in the final body weight, average body weight gain, and specific growth rate with increasing stocking density. The highest final body weight (732.64 g), body weight gain (694.30 g) and specific growth rate (0.89 % day-1) were recorded in 10/m2 stocking density with feed ration of 6% body weight. In contrast to this, fish reared in higher stocking density (25/m2) exhibited poor feed conversion ratio. Fish reared in lower stocking density (10/m2) and fed with 6% feeding ration displayed an enhanced feed conversion ratio, feed efficiency ratio and protein efficiency ratio which indicated that rearing of stunted rohu in intensive cage culture at lower stocking density (10/m2) with higher feeding ration (6%) increase their feed utilization capacity. Interpretation: Rearing of stunted rohu in intensive cage culture is possible, however, the stocking density and feeding ration should be 10/m2 and 6%, respectively, compared to traditional cage practices, in order to reduce stress and to get optimum production.

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.

Yucca Schidigera

Ammonia is a critical hazardous nitrogen metabolic product in aquaculture. Despite trials for its control, ammonia intoxication remains one of the most critical issues to overcome. In this study, we explored the modulatory effect and potential mechanism by which Yucca schidigera extract (YSE) can ameliorate ammonia intoxication-induced adverse effects on tilapia health and metabolism. A total number of 120 Nile tilapia were evenly assigned into four groups with three replicates each. The first group served as normal control group; the second group was exposed to ammonia alone from the beginning of the experiment and for four weeks. The third group was supplied with YSE in water at a dose of 8 mg/L and exposed to ammonia. The fourth group was supplied with YSE only in water at a dose of 8 mg/L. YSE supplementation succeeded in improving water quality by reducing pH and ammonia levels. Moreover, YSE supplementation markedly alleviated chronic ammonia-induced adverse impacts on fish growth by increasing the final body weight (FBW), specific growth rate (SGR), feed intake and protein efficiency ratio (PER) while reducing the feed conversion ratio (FCR) via improvements in food intake, elevation of hepatic insulin-like growth factor (ILGF-1) and suppression of myostatin (MSTN) expression levels with the restoration of lipid reserves and the activation of lipogenic potential in adipose tissue as demonstrated by changes in the circulating metabolite levels. In addition, the levels of hepato-renal injury biomarkers were restored, hepatic lipid peroxidation was inhibited and the levels of hepatic antioxidant biomarkers were enhanced. Therefore, the current study suggests that YSE supplementation exerted an ameliorative role against chronic ammonia-induced oxidative stress and toxic effects due to its free radical-scavenging potential, potent antioxidant activities and anti-inflammatory effects.

A total of fifty 3-4 weeks old albino rats of the Wistar strain weighing 50-60g were randomly allocated to five dietary treatments in a completely randomized block design to investigate the growth performance and nutrient digestibility of the rats fed diets containing processed dehulled jack bean. Five diets were formulated to contain casein (T1)-control diet, dehulled jack bean soaked in filtrate obtained from raw pap(T2), dehulled jack bean soaked in lye solution (T3), dehulled jack bean boiled for 15minutes (T4) while a protein free diet served as a negative control (T5). The experiment lasted for 28-days.Dehulled jack bean significantly (P>0.05) influenced the growth parameters measured for the Wistar rats. Rats on control diets had the highest value for all the growth indices, feed intake (210.90g), final body weight (103.40g), body weight changes (41.90g), feed conversion ratio (5.10) and protein efficiency ratio (1.41). Rats on T2 (soaked in ‘ogi’ liquor) had feed intake value of (147.40g), followed by rats on T4 (boiled for 15minutes) (117.00g), T5 (negative control) (119.07) and T3 (soaked in lye solution) (79.40g) respectively. Rats on T4 had the highest value for final body weight (67.80g), body weight changes (6.30g), feed conversion ratio (12.27) and protein efficiency ratio (0.25) while rats on T3 had the lowest value for final body weight (67.80g), body weight changes (-32.45g), total feed intake (79.40g) with FCR of (-0.96) for the tested diets. Wistar rats placed on lye treated diet had depressed body weight changes of 59.8% compared to the control. Digestibility studies however showed that rats on control diets had the highest digestibility value of DM and other nutrients, while there was no significant (P<0.05) difference in digestibility value of CF, significant (P>0.05) differences existed in DM, digestibility value of CP, EE and Ash. Rats on T3 and T5 had the lowest digestibility value for Ash (11.48) and CP (37.66). Rats fed dehulled jack bean seed soaked in ogi liquor and boiled for 15minutes showed slight improvement in growth performance and nutrient utilization over those fed lye soaked jack bean. All the processing methods were ineffective when compared to the performance of rat fed casein based diets.
