Recirculation Aquaculture System

The high market demand for Pangasius (Pangasius sp.) has encouraged farmers to adopt a cultivation system with high stocking densities and high feeding rates. This causes fish farming waste to increase and ammonia in the waters also increases, resulting in a decrease in water quality. One of the efforts to overcome this problem is by using Recirculation Aquaculture System (RAS). This study aims to examine the effect of filters with different media compositions in RAS of Pangasius. Test fish, average weight of 4.59 g, kept for 30 days in aquarium with a density of 1.15 g.L-1. The feed is given at satiation, twice a day. There were five treatments and four replications during study. The treatments were the difference composition of filter media, i.e. A (100% zeolite), B (25% net + 75% zeolite), C (50% net + 50% zeolite), D (75% net + 25% zeolite), and E (100% net). Dacron was used as a mechanical filter in all treatments. The results showed that the composition of different filter materials had a significant effect (P <0.05) on Survival Rate (SR), Total Amount of Feed Fed (TFF), Relative Growth Rate (RGR), and Feed Conversion Efficiency (FCE). The best performance was showed by media biofilter composition of 25% nets + 75% zeolite, with the value of VTR (Volumetric Total Ammonia Nitrogen Removal) were 55.45-66.32 g.m-3.day-1, SR was 93.75%; TFF was 124.84 g; RGR was 2.13%.day-1, and FCE was 46.87%. Various different compositions of net and zeolite as filter media on RAS were able to manage TAN below tolerance limit.Keywords: catfish, recirculation system, filter composition, dacron, net, zeolite.

Abstract The objective of this study was to evaluate the the influence of feeding rate and different artificial substrates on both the water quality and growth performance of Litopenaeus vannamei shrimp. The experimental design was randomized blocks with five treatments and four replicates, with a density of 30 shrimp m-2 and mean weight of 2.8 g. The experiment lasted 49 days, and during this period, artificial substrates did not influence the water quality. The increase in the feeding rate influenced the dissolved oxygen of treatments. The final average weight, average final length, final biomass, productivity, and feed conversion rate showed significant differences (p > 0.05). The best food conversion factor was provided by the treatment with a feeding rate of 2%. The treatment with a feeding rate of 4% of biomass showed the best growth performance, except for the feed conversion rate. Results showed that for the percentage of 25% of the area of artificial substrates, there is an optimum feeding rate of between 5.13% and 5.54% of shrimp biomass, resulting in maximum production.

Abstract Biofloc technology system (BFT), recirculation aquaculture system (RAS) and polyculture promote efficient use of water, area and nutrient recycling, which are essential practices for sustainable aquaculture development. The aim of this study was to evaluate the growth, feed efficiency, biofloc composition and water quality of Nile tilapia Oreochromis niloticus (Linnaeus, 1758) in monoculture and polyculture with giant freshwater prawn Macrobrachium rosenbergii (De Man, 1906) in BFT and RAS, over a period of 30 days. Fish (n = 128; 7.29 ± 0.67 g) were distributed randomly in 16 experimental tanks (8 fish/tank). Prawn (n = 96; 0.50 ± 0.09 g) were allocated in 8 experimental tanks (12 prawn/tank) in a polyculture. The experimental design was completely randomized with four treatments with four replicates each, in a factorial design 2 × 2 (BFT and RAS vs. monoculture and polyculture). The experimental diet (28% of digestible protein; 3100 kcal kg−1 of digestible energy) was used both to fish and prawn in BFT and RAS. There was significant effect (p < 0.01) of the system and the culture for weight gain, apparent feed conversion and protein efficiency ratio. The average weight gain and apparent feed conversion of tilapia in monoculture (30.04 g and 1.39) and in polyculture (36.44 g and 1.27) were superior (p < 0.01) in BFT than in monoculture (23.64 g and 1.74) and in polyculture (24.14 g and 1.61) in RAS. Weight gain and survival of giant freshwater prawn was superior (p < 0.01) in BFT (0.43 g and 87%) compared to RAS (0.26 g and 79%). The data showed that BFT provides better growth performance responses in monoculture for Nile tilapia and in polyculture with giant freshwater prawn compared to RAS.

Water quality and waste management are significant problems for aquaculture in Indonesia, including catfish (Clarias gariepinus) aquaculture. A combination of Aquaponics Systems and Recirculating Aquaculture Systems (A-RAS) has been developed to address this problem. This study analyzed A-RAS application for catfish (Clarias gariepinus) aquaculture by comparing water quality and production indicators between A-RAS and conventional methods. The results show that temperature, pH, dissolved oxygen, total organic matter, ammonia, nitrate and nitrite in A-RAS technology were 28.0-30.0°C, 6.5-7.9, 3.8-7.8 mg/L, 18.54-24.97 mg/L, 0.12- 0.28 mg/L, 0.12-0.13 mg/L, and 0.04-0.13 mg/L, respectively. Survival Rate, Feed Conversion Ratio, and harvest in A-RAS application were 85.5%, 1.1, and 26 kg/m³, respectively. A-RAS technology can maintain water quality to be reused in cultivation and increase yields by about 13%. Besides, water spinach can be an additional income for farmers.

This study aims to determine the adaptation of Seluang fish (Rasbora agryotaenia) based on the domestication stage of Sebangau waters. This research started in January until February 2018. The research method used is a survey and experimental observation. The size of the tarpaulin pond used for domestication is 2 x 3 m, with a water height of 30 cm. The number of fish sampled is 200 heads. Feed is given as much as 5% of the total weight of the fish kept, feeding done twice a day (morning and afternoon). This domestication activity is still not perfect, because only part of the life cycle of fish (Rasbora agryotaenia) can be done in the cultivation system (survival and eating commercial feed). During maintenance activities, the amount of feed used was 63.840 g with the final weight of the fish was 16.905 g. Survival rate (SR) of fish (Rasbora agryotaenia) during maintenance was 73.5% and deaths 26.5%. From the calculation is known that the Feed Conversion Ratio (FCR) for fish (Rasbora agryotaenia) 2.8. This domestication stage starts with the preparation of maintenance pools, fishing in nature, sorting, distribution, and maintenance. During maintenance, five samples of sample fish were taken and five times the pool water quality measurement. From the five weights of the sample fish, it is known that the average weight of the fish is kept, I = 0.003 g, II = 0.042 g, III = 0.051 g, IV = 0.082 g, V = 0.115 g. From the measurement of water quality of tarpaulin ponds, it is known that the mean value of water quality parameters, for DO ranges from 1.5 to 8.8 mg / L, the pH ranges from 5.5 to 7.2 and temperatures range from 27.4 to 27.7 0C.

A comparison was conducted for growth criteria of common carp, Cyprinus carpio larvae cultivated in earthen ponds and recirculation aquaculture system (RAS) depending on live foods (phytoplankton and zooplankton stimulated by buffalo fertilizers in earthen ponds, while the larvae cultivated in RAS were feed on Artemia larvae reproduced in vitro, in addition to manufactured pellets (38% crude protein) for common carp in both systems. Three 2500 m2 earthen ponds were cultivated for 90 days with larvae of initial weight 0.002 g at different numbers (40800 larvae for pond 1, 55600 larvae for pond 2 and 36400 larvae for pond 3). These larvae depend on natural food for 19 days, then fed on manufactured feed. Fishes were weighed every 19 days to change daily feed. Three replicates of RAS plastic tanks (100 letter capacity) cultivated for 90 days with 0.002 g larvae at a density of 2 larvae per one liter (160 larvae at each plastic tank). These larvae fed for 15 days to saturation (4 meals daily) with Artemia larvae and small Artemia, then fed on manufactured feed. Subsequently, fishes were weighed every 15 days to change daily feed. Larvae cultivated in earthen ponds recorded weight gain of 26.90 g, daily growth of 0.30 gday-1, relative growth of 1345000%, specific growth of 10.56 %day-1, feed conversion of 1.25 and survival rate of 13.16%. Larvae cultivated in RAS system recorded weight gain of 1.53 g, daily growth of 0.02 gday-1, relative growth of 76200%, specific growth of 7.37 %day-1, feed conversion of 2.82 and survival rate of 72.32%. Statistical analysis of results revealed significant differences (p>0.05) in all growth criteria for larvae cultivated in both systems. Final conclusion that earthen pond was better than RAS systems in producing fingerlings of common carp.

The study was carried out for 138 days to know the growth and survival rate of P. monodon by applying probiotics in Gazi Fish Culture Ltd. Dacope, Khulna, Bangladesh. Six experimental ponds (4000 m2 in size i.e. one acre) were selected of which three were probiotic ponds and three were controlled. After pond preparation, PL15 (average weight of each 4.75±0.09 g) was stocked at the rate of 13 per m2 following polymerase chain reaction (PCR) test. CP NASA shrimp feed was used during the study period.  Transparency, salinity, pH, dissolved oxygen (DO), temperature, total Ammonia Nitrogen (TAN) were recorded by standard measurements. The average final body weight of the harvested shrimp is 37.67±1.15 g in probiotics ponds and 27.33±0.58 g in controlled ponds and the difference was significant (P < 0.01) between these two productions. The average survival rate was 90.67±1.15 % in probiotic pond and 71.00±3.0 % in controlled pond. The average daily gain (ADG) in weight was 0.27±0.01 g and 0.19±0.01 g in probiotic and controlled ponds, respectively. The result showed that probiotic plays an important role in maintaining water quality parameters, soil quality and health management as well as increases the growth and survival of shrimp.Key words: Probiotics; P. monodon; Water quality parameter; Growth rate; Survival rate.© 2013 JSR Publications.

The Impact

Efforts to reduce the impact of waste improvement on degradation of water quality can be transferred by utilization of inorganic waste as a source of seaweed nutrition. This study aimed to determine the growth and protein content of Ulva prolifera maintained at different flow rates in integrated aquaculture system. 9 Yellowtail stocked with 5.095 g with an average weight of 566.11±81.51 g were kept in 540 L tank for 24 days, by water flowing at the rate of 10 L min-1. Water from the fish tank was distributed into the sediment tank and go to 6 Ulva tanks with the flow rate of 0.5, 1.0 and 1.5 L min-1. Test parameters measured were growth performance of Yellowtail, biomass of Ulva prolifera, protein content of Ulva prolifera, and total ammonia nitrogen. The measurement results showed that the biomass of fish increased to 5.408 g, then biomass of Ulva increased to 42 g, 156 g and 155 g for flow rate of 0.5 L, 1 L and 1.5 L min-1, respectively. The protein content of Ulva for all the treatments was the same (P> 0.05). A total of ammonia in the tank outlet of Ulva (0.0202 - 0.1137 mg N L-1) were smaller than those were in the inlet (0.0286 - 0.1394 mg N L-1).

Optimum feeding schedule is one of the main things for the proper growth of fish and other animals. A study was conducted to optimize the effects of different feeding frequencies on growth performance and production of Rui (Labeo rohita) under pond cage culture system in Rajshahi, Bangladesh. Labeo rohita with an average weight of 302.23±4.07g (mean ± SD) were randomly stocked in 9 cages at 30 fish/cage in all the treatment. Fish were fed (4% of body weight) a commercial floating feed with three different feeding schedules: feeding of fish thrice daily in T1treatment; twice in T2 treatment and once in T3 treatment. Water quality parameters were measured during the study period. The physico-chemical parameters of pond water were within suitable ranges for fish culture in cages. The obtained values of the water quality parameters were temperature 28.26 to 28.46°C, pH 6.91 to 6.94, DO 5.04 to 5.33 mg/l, CO2 2.95 to 3.02 mg/L. The mean final weight gain was significantly highest in T1 (345.05 g) a followed by T2 (324.66 g) and T3 (257.82 g). The Specific growth rate (SGR) value were significantly higher in T1 treatment (0.91% bwd-1; Body weight per day) than T2 (0.87% bwd-1) and T3 treatment (0.73% bwd-1). The feed conversion ratio (FCR) value was significantly lower in T1 fish group (2.72) than other two T2 (2.84) and T3 (3.44) treatments. The fish productions were 18.13, 17.55 and 15.67 kg/cage/cycle in T1, T2 and T3 respectively. The highest net profit was found (Bangladeshi Taka, BDT 1445.38) in T1 compared to T2 (BDT 1329.24) and T3 treatment (BDT 937.99). The cost benefit ratio (CBR) was significantly higher in T1 (0.57) than T2 (0.53) and T3 (0.37). The feeding schedule three times in a day was most suitable than other two schedules.
