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 study was conducted to assess the growth and production of Thai sarpunti (Puntius gonionotus), tilapia (Oreochromis niloticus) and rui (Labeo rohita) under monoculture and polyculture systems in seasonal waterbodies of haor environment. Selected waterbodies were divided into three treatments as T1 (sarpunti), T2 (sarpunti+tilapia) and T3 (sarpunti+tilapia+rui). Each treatment had three replicates and same stocking density (40,000 ha-1) of fishes was maintained in all treatments. Stocked fishes were fed with rice bran and wheat flour as supplemental feed at a decreasing rate of 10-5% of total biomass for twice daily. The highest final weight of sarpunti (122.32 g), tilapia (102.58 g) and rui (140.0 g) was obtained in T1, T2 and T3, respectively. Significantly higher production of sarpunti was secured in T1 (3,446.13 kg ha-1) than T2 (2,942.6 kg ha-1) and T3 (2,804.1 kg ha-1), and tilapia production was better in T2 (2,786.07 kg ha-1) than T3 (2,172.52 kg ha-1). Combined production of sarpunti, tilapia and rui was significantly (p<0.05) higher in T3 (8,341.41 kg ha-1) followed by T2 (5,728.67 kg ha-1) and T1 (3,446.13 kg ha-1). Therefore, polyculture practice of sarpunti, tilapia and rui may be suggested to disseminate at farmers’ level for boost up fish production.

The Impact

Abstract The integrated farming activities have become more popular in the last decade. It expects to increase productivity by optimizing the land and minimizing environmental pollution. The study aims to understand the perception level of society towards the environmental pollution of the integrated livestock-fish production system on raising catfish and laying duck (Clarias sp and Anas platyrhynchos). The study was conducted in Desa Balunijuk, Bangka. The questionnaire was used for the data collection technique through a face-to-face interview by following the health protocol of Covid-19. Two stages of data collection were applied: before and after treatment of Probio_Fm. Qualitative descriptive was employed to analyze the data. The respondents were the society who lived nearby the location of the study. A mixture of probiotics was employed on the feed and the catfish pond. The study found that the perception was significantly different between before and after treatment of Probio_Fm particularly on the negative environmental effects such as odor pollutants due to unmanaged animal waste. It occurred at the very beginning of the study during the wet season before the probiotic treatment. Interestingly, during the dry season, the probiotic treatment was regularly applied. The odor pollutant impact decreased even not having a bad odor at all. The waste both absorbed in the sand and was streamed through the drain pipeline. However, most of the respondents were not disturbed due to the odor pollutant surrounding the integrated livestock-fish production system. It articulated that the probiotic treatment worked effectively in unraveling the bacteria so that the pollutant level decreased drastically. The study recommended various solutions to the problems: the draining pipeline should be repaired, the animal feed should use probiotics to achieve optimal use of nutrition, consistent and effective feeding should be applied, and the cleanliness of the duck house should be properly maintained. The monitoring and evaluation of the environmental impact towards the integrated livestock-fish production system should involve relevant stakeholders such as a village government, the management, and society as a whole so that the healthy and environment-friendly integrated fisheries activity can be achieved.

Tilapia is a popular fish for consumers and aquaculture in every part of Thailand. This study was conducted to determine the level of mineral supplementation in the diet for the growth of red tilapia fingerlings, which gave the lower fish production cost. The fingerlings with an initial average weight of 3.1 ± 0.48 g and a length of 2.5±0.24 cm were raised in 3 m3 concrete tank with 1.5 m3 of water volume at 20 fish/m2 stocking density. Fish were fed with pellets diet (28 % crude protein), which contained different levels of mineral supplements (0 (control), 20 and 40 g/Kg) in triplicate replications. The experiment was conducted within 80 days. The results showed that fish fed with diet3 had better average daily weight gain (ADG) and food conversion ratio (FCR) than diet2 and diet1 significantly (P<0.05). The ADG and FCR of fish fed with diet3 showed 0.70 ± 0.02, 1.72 ± 0.02 respectively, but there was a non-significant difference in survival rate from all treatments (P>0.05), and the fish production cost of diet 3 is lower than those in diet1 and diet2. Thus, this experiment concluded that minerals supplementation at the level 40 g/kg diet were suitable for tilapia aquaculture.

The experiment was carried out under three treatments each with two replications. Fish population density was 80 fish per decimal (silver carp 32, tilapia 32 and mrigal 16) under treatment-1, 120 fish per decimal (silver carp 48, tilapia 48 and mrigal 24) under treatment-2 and 160 fish per decimal (silver carp 64, tilapia 64 and mrigal 32) under treatment-3. The average initial length and weight of the fingerlings of silver carp, tilapia and mrigal were 7.49, 5.12, and 5.56 cm and 8.00, 2.00 and 1.50 g respectively. The ponds were fertilized fortnightly with cowdung, urea and TSP (triple super phosphate) at the rates of 5 kg, 60 g, and 90 g per decimal, respectively. During the experimental period, the range of water temperature (30.20 to 32.90°C), transparency (28 to 38 cm), dissolved oxygen (8.20 to 10.60 mg/L), pH (6.90 to 7.90), total alkalinity (92.00 to 127.00 mg/L), free CO2 (1.00 to 1.60 mg/L), phosphate-phosphorus (1.00 to 1.90 mg/L), and nitrate-nitrogen (1.90 to 3.90 mg/L) were within the productive range and more or less similar in all the ponds under three treatments. There were 25 genera of phytoplankton under five major groups and 10 genera of zooplankton under three major groups in the experimental ponds. The calculated net fish production of the ponds under treatment-1 was 2.62 ton/ha/yr and that of the ponds under treatment-2 was 4.42 ton/ha/yr and that of the ponds under treatment-3 was 5.18 ton/ha/yr. The net fish production under treatment-2 and treatment -3 were 195.58% and 229.20% higher than that of treatment-1, taking net fish production under treatment-1 for 100%. According to profit-cost analysis the ratios of net profit and total cost under treatments 1, 2, and 3 were 1:0.25, 1:0.45, and 1:0.44. According to growth and production treatment-3 is the best, and according to the profit-cost analysis, treatment-2 (ratio 1:0.45) is the best but it is almost same to that of treatment-3. So, the population density of 160 fish per decimal (under treatment-3) might be considered best. It seems that proper determination of stocking density of different fishes in polyculture is very important to increase fish production.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16566Progress.

Aquaculture is the fastest-growing food-producing sector in the World and has exhibited continuous improving in total production throughout the recent decades. A carp polyculture experiment was carried out to evaluate the growth performance of major carps in semi-intensive fish culture system. Two earthen ponds located at Kadirganj of Boalia thana under Rajshahi district of Bangladesh were selected to study the effect of fertilizer (organic as cowdung and in-organic as triple super phosphate) in supplemented ponds on the growth of carps. Pond -01 was fertilized with cowdung and TSP at the rate of 1728 and 20 kg/h respectively, at 10-day intervals. Pond -02 was without fertilizer. Each pond was stocked with 30% Labeo rohita, 20% Catla catla, 15% Cirrhinus mrigala, 15% Hypophthalmichthys molitrix, and 20% Cyprinus carpio with a total stocking density of 10000/ha. Both ponds were supplemented with mustard oil cake, rice bran and maize bran at the rate of 2.5 kg/ha for each, given for a period of six months as daily basis. The net fish production was found to be 2605 and 1795 kg/ha/year in pond -01 and pond -02, respectively. The results showed that fish production was significantly higher in pond -01 than pond -02 (P<0.05). Pond -01 showed 1.45 times greater fish production than that of pond -02. The results of this study provided invaluable information for the sustainable aquaculture, as well as providing an important baseline for future studies within Bangladesh and surrounding developing countries.DOI: http://dx.doi.org/10.3126/on.v9i1.5727
