Abstract Broodfish conditioning of climbing perch (Anabas testudineus) is conducted in earthen ponds with a density of 2-4 kg m-2, at a 1:1 male to female ratio. Homemade or commercial feeds containing 22-25% crude protein are given as feed for the broodfish. To induce spawning, HCG and LH-RHa are used. Nursing from fry to fingerlings is done in earthen ponds with densities of 500-600 fry m-2. After nursing for 50-60 days, when the fish reach 4-5 cm length, they are harvested and stocked in grow-out systems. Fingerlings are stocked in grow-out ponds at a density of 20 fish m-2. Homemade and commercial feeds containing 22-25% crude protein are used to feed fish. After 6 months, the fish can reach the marketable size of 60-100 g per fish. The stocking density of fish in rice fields is lower, at 3 m-2. They feed on natural food found in the rice field. Homemade feeds are also added as supplementary feed. Rice-fish culture covers two continuous paddy rice cropping periods, or one paddy rice crop and one flooded crop.

Potentials and prospects of pond fish farming in improving aquaculture system in Kaliakair upazila under Gazipur district, Bangladesh were investigated. Data were collected from 60 selected fish farmers through questionnaire survey and Focus Group Discussion (FGD) during June to November, 2014. The research revealed that a highest number of pond fish farmers (61.67%) were out of training facilities and a good portion (23.33%) had no education. Pond water was found turbid seasonally (71.66%) and farmers did not exchange water during culture periods (66.67%). As a result water quality deteriorates day by day and depletion of oxygen occurs during pond farming. The average stocking density of fish was higher in the study area and the highest was found in monoculture of Climbing perch (Anabas testudineus ) (1200 individual/decimal) and lowest in carp polyculture system (195 individual/decimal). Fish production was higher in Pangus monoculture system (17.89 MT/ha/yr) and lower in Climbing perch monoculture system (10.78 MT/ha/yr), but profit was higher in Climbing perch monoculture produced 1318100 Tk./ha/yr and lower in Tilapia monoculture 397886 Tk./ha/yr. Benefit Cost Ratio was higher in Climbing perch (2.32) and lower in Pangus culture (1.34). The problems faced by the fish farmers were broadly categorized as financial, natural, technical and social. Therefore, necessary training facilities with institutional and organizational supports, credit facilities, extension services and awareness development are essential to improve aquaculture system as well as the fishers’ livelihoods in Kaliakair upazila of Gazipur district.Res.

Climbing perch is one of economically-valued local fish in Indonesia, particularly in Borneo, Sumatra, and Java Islands. The fish has the potential to be developed as freshwater aquaculture species. The purpose of this experiment was to evaluate the production performance and blood profile of climbing perch cultured in peat pond with different stocking densities. The research was conducted in Kereng Bangkiray Village, Sebangau District, Palangkaraya City, Central of Borneo. Nine fish ponds sized 5.0 m x 5.0 m x 1.5 m were used. Nets with a mesh size of 1 cm measuring 2.0 m x 1.5 m x 1.0 m was installed in each fish pond for the experiment. The treatment consisted of different stocking densities, namely 15 fish/m2, 30 fish/m2, and 45 fish/m2. Fish with the body weight of 20 ± 1.25 g were used. Fish were cultured for four months. An artificial diet containing 30% protein was given with a feeding rate of 5%. The experiment was designed in a complete randomized design. The result showed that the production performances (i.e. survival, specific growth rate, absolute weight, and biomass) were significantly higher at the densities of 15 and 30 fish/m2 than that of 45 fish/m2 (P<0.05). Blood profile such as glucose, erythrocyte, leucocyte, and hemoglobin were higher at the density of 45 fish/m2 except for hematocrit which was higher at the densities of 30 and 15 fish/m2. Water quality parameters such as dissolved oxygen, nitrite, nitrate, and ammonia at the densities of 15 and 30 fish/m2 showed better values than that of 45 fish/m2 stocking density. To optimize the productivity and maintain the optimum water quality condition, the optimal stocking density for climbing perch culture is suggested at 30 fish/m2.

Abstract In China, conditioning of freshwater prawn (Macrobrachium nipponense) broodstock is conducted in earthen ponds at a density of 45-60 g m-2, at a ratio of 3-4 females to 1 male (Liu, 2004). Mixed feed and fresh food of animal origin are used for broodstock. Mating occurs when temperature rises above 18°C. Gravid prawn are stocked in cages at a density of 0.5 kg cage-1. After 20-25 days, prawn larvae hatch. Nursing is done in earthen ponds at a density of 2,000 prawns m-2. When the larvae grow to 0.8-1.0 cm long, the density should be reduced to 1,000 prawns m-2 or lower. After nursing for 20-30 days, when the prawns reach more than 1.0 cm, they can be stocked in grow-out systems. Two crops are possible in one year in south China and one crop in the north. Commercial feeds containing 35-40% crude protein are used to feed prawns.

An on-farm experiment was undertaken in nine earthen ponds to evaluate the growth and production potentials of stinging catfish shing, Heteropneustes fossilis for the period of six months from March to August 2010. Three stocking densities such as 1,25,000 (T1), 1,87,500 (T2) and 2,50,000 ha-1 (T3) were tested with three replications each. Fish were fed with commercial pelleted feed containing 35% crude protein. After six months rearing, the mean harvesting weights of shing were 69.42±6.20, 58.74±3.85 and 49.50±4.52g in T1, T2 and T3, respectively. Significant (P<0.05) highest mean harvesting weight was found in T1. The best survival was found in T1 (87%) among the treatments. The calculated mean production of shing (H. fossilis) in three treatments such as T1, T2 and T3 were 7549±52, 9031±71 and 8786±60 kg ha-1, respectively, which were significantly different (p<0.05) from each other.

Abstract Rice fish culture has been practiced for a long time in the northern uplands of Vietnam. It is quite an extensive farming practice using space in the rice fields for local fish species such as common carp (Cyprinus carpio) and crucian carp (Carassius carassius) and utilizing natural food produced from manure fertilisation. In the last decade, improved culture techniques have been introduced through development projects and rice-fish culture systems are being gradually improved. The rice fields were modified, with trenches and fish refuges constructed. Cultured species were diversified, which included grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix), Nile tilapia (Oreochromis niloticus) and silver barb (Barbonymus gonionotus). Local farmers became aware of the benefits of using large size fingerlings and a suitable stocking density. Apart from the natural food found in the rice fields, agricultural by-products were used as supplementary feed for fish. As a result, fish yields significantly increased. In addition to rice, farmers can obtain about 440 kg of fish ha-1 of rice field.

AbstractDiseased Anabas testudineus exhibiting signs of tail-rot and ulcerations on body were collected from a fish farm in Assam, India during the winter season (November 2018 to January 2019). Swabs from the infected body parts were streaked on sterilized nutrient agar. Two dominant bacterial colonies were obtained, which were then isolated and labelled as AM-31 and AM-05. Standard biochemical characterisation and 16S rRNA and rpoB gene sequencing identified AM-31 isolate as Aeromonas hydrophila and AM-05 as Aeromonas jandaei. Symptoms similar to that of natural infection were observed on re-infecting both bacteria to disease-free A. testudineus, which confirmed their virulence. LC50 was determined at 1.3 × 104 (A. hydrophila) and 2.5 × 104 (A. jandaei) CFU per fish in intraperitoneal injection. Further, PCR amplification of specific genes responsible for virulence (aerolysin and enterotoxin) confirmed pathogenicity of both bacteria. Histopathology of kidney and liver in the experimentally-infected fishes revealed haemorrhage, tubular degeneration and vacuolation. Antibiotic profiles were also assessed for both bacteria. To the best of our knowledge, the present work is a first report on the mortality of farmed climbing perch naturally-infected by A. hydrophila as well as A. jandaei, with no records of pathogenicity of the latter in this fish.
