The present study was conducted to know the culture strategies and fish health and disease problems in pond aquaculture in Mymensingh, Bogra and Pabna districts of Bangladesh. Questionnaire interview and participatory rural appraisal tools like focus group discussion (FGD) were conducted with selected fish farmers. In total 90 farmers were interviewed and 9 FGD sessions were conducted. Most of the respondents practiced carp and pangas polyculture and they had disease problems in their ponds. Prevalence of fish disease varied with cultured species and locations. The most prevalent diseases as reported by the farmers were pop eye (57.78%), ventral reddening (55.55%), tail and fin rot (48.89), hemorrhagic lesion over the body surface (45.56%), dropsy (40%), gill rot (40%), white spot (40%) and epizootic ulcerative syndrome or EUS (33.33%). According to farmers opinion most susceptible species to disease was silver carp, Hypophthalmichthys molitrix (57.78%); followed by mrigal, Cirrhinus cirrhosus (50%); catla, Catla catla (47.78%); sarputi, Barbodes gonionotus (47.78%); rui, Labio rohita (42.22%) and pangas, Pangasianodon hypophthalmus (42.22%). Higher mortality was found in pangas (53.56%). Clinically, pangas, koi and sarputi were found severely affected. Most of the farmers used some treatment measures against disease problems. This study also highlited some fish health management problems in pond aquaculture. Further studies should include identification and characterization of pathogens involved in different types of diseases in pond aquaculture. DOI: http://dx.doi.org/10.3329/jbau.v11i2.19944 J.

In order to understand the existing status of aqua-medicines and chemicals in aquaculture activities present investigation was conducted from January to June 2017 in four upazilas of Bogura district namely, Bogura Sadar, Sherpur, Kahaloo and Shibganj. Questionnaire and focus group discussion were used for data collection. Among the latest aquachemicals, geotox, jv zeolite, mega plus, aquastar pond, acme's zeolite, zeo-fresh, aqua green, biomin pond life, aquakleen, megagio gold, and aqua boost were extensively used. Probiotics like profs, aqua photo, aqua gold, super biotic and pond care were used. The selected farmers used growth promoter such as saltose, panvit aqua, spa gelly, aqua boost and bio-pond, bio-grow, aqua pure, gasstrap, metrix, geo-rich bio-aqua 50 and aqua magic were used as toxic gas reducer. Approximately 11 trade names of antibiotics were marketed in the selected area. Their main active ingredients were chlortetracycline, oxytetracycline, amoxicillin, co-trimoxazole, azithromycin and sulphadiazine. The survey identified some problems connected with the practice of such chemicals such as shortage of fish farmer’s knowledge about the usage of chemicals, proper dosage and their maintenance. Res.

Live Fish

In the present study, different means of transportation of live table fish in Sherpur Fish Market, Ludhiana District in Punjab were investigated. Two methods, one for short distance (travel time <2h) and the other for long distance transportation (travel time 2-6 h), were studied. The transportation method for short distance was with tricycle-rickshaw either pulled by humans or by a moped, wherein, a wooden cuboid (1.5x1.0x1.0 m) with internal polythene lining was used with a carrying capacity of 50-100 kg fish. In the long distance transportation method, polythene lined truck-pool of 3.1x1.83x0.75 m was used and about 600-700 kg fish per truck-pool was transported. About 50 to 100% fish mortality was observed in the long-distancecarriage or truck-pool method, whereas, only 10- 20% mortality was recorded in short-distance-carriage or cart method. The fish transported were primarily carps weighing 300-1500 g each and comprised catla (catla catla ), rohu (Labeo rohita), mrigal (Cirrhinus mrigala), common carp (Cyprinus carpio), big-head carp (Hypophthalmichthys nobilis) and silver carp (Hypophthalmichthys molitrix). The live fish packaging and transportation were used as a means of value addition to ensure fresh quality and added market price per unit fish. The retail price of live table carps ranged from `120-200 kg-1 based on species of fish and its size, whereas, the dead and iced fish was priced below `100 kg-1. The major problems faced in live fish transportation were lack of aeration of water during transportation, inconvenient and cumbersome nature of existing method and accident proneness. The study suggested the need for scientific intervention in mainly two aspects such as: 1) to develop a handy method of live table fish transportation compatible to truck-pools and 2) to develop an aerator appropriate for the live-fish transportation containers in order to overcome the existing problems.

The paper presents the analysis results of the body weight and length variability (body mass, zoological length, length up to the end of middle fin rays, fatness, mass-accumulation coefficient, growth), fish-productivity and gross-production in 4-year-old and 5-year-old Russian sturgeons ( Acipenser gueldenstaedtii , Brandt) cultivated in adapted ponds together with herbivorous fishes (grass carp ( Ctenopharyngodon idella ), silver carp ( Hypophthalmichthys molitrix ). The analysis helped to reveal some regularities about variability of 4-year-old and 5-year-old Russian sturgeons ( Acipenser gueldenstaedtii , Brandt) cultivated in artificial ponds adapted for carp breeding. The paper gives average values of body mass and length, variability characteristics, according to biological statistic parameters; analysis of absolute growth in different age groups of the Russian sturgeon cultivated at the pond carp farms. Gross-production values for 4-year-old and 5-year-old sturgeons are recommended to be taken as 337 and 450 kg/ga, correspondingly. It should be noted that 450 kg/ga is not considered as an ultimate gross-production value for the Russian sturgeon cultivated in the fish farms adapted for carp breeding.

Tilapia tilapinevirus, also known as tilapia lake virus (TiLV), is an emerging fish virus that primarily affects tilapines. However, the virus has also been detected in a few non-tilapines. As tilapia is generally farmed in polyculture systems along with carps in South Asian countries, there is a likelihood that TiLV-infected tilapia can transmit the virus to the co-cultured species. In view of the above, the susceptibility of three carp species, namely catla (Catla catla), mrigal (Cirrhinus mrigala) and silver carp (Hypophthalmichthys molitrix) was evaluated vis-à-vis tilapia, following experimental infection with TiLV. No clinical signs and histopathological alterations could be observed in carps. RT-qPCR revealed that TiLV copy numbers in liver and brain of all the three carps were almost negligible and did not show any increase with time, suggesting that the virus did not replicate in liver and brain, the target organs of TiLV. Further, TiLV could not be isolated from pooled liver and brain tissues of carps using permissive CFF cell line. On the contrary, in tilapia, typical clinical signs and histopathological lesions were observed and there was significant increase in TiLV copy number up to 6 days post-injection. Furthermore, the virus was successfully isolated from pooled liver and brain tissue of infected tilapia. From the above findings, it could be concluded that C. catla, C. mrigala and H. molitrix are resistant to TiLV infection and unlikely to be carriers for this virus.

Breeding Techniques

An investigation was carried out to know the induced breeding techniques of some firewater fish species such as rui (Labeo rohita), catla (Catla catla), silver carp (Hypophthalmichthys molitrix), grass carp (Ctenopharyngodon idella), common carp (Cyprinus carpio), bighead carp (Hypophthalmichthys nobilis), sharpunti (Puntius sarana) and bata (Labeo bata) at Ma Fatima Fish Hatchery in Chanchra, Jashore, Bangladesh. The cost-benefit analysis was also performed on this hatchery for three months from May to July, 2016. The brood fishes purchased from different local sources were used for spawning. The hatchery mainly practiced induced breeding by maintaining proper age and weight of brood stock during spawning. The ranges of fertilization and hatching rates of the experimental fishes were 80.04±1.44 % to 94.35±0.54% and 75.34±3.49% to 88.68±2.76%, respectively. Total spawn production was 960, 862 and 734 kg, and the total revenue income from spawn sell was BDT 2,883,500, 2,355,100 and 1,844,800 (BDT 85 = 1 US$) in May, June and July, respectively. Estimated capital cost was BDT 87,90,000, while the operating costs were BDT 1,810,650; 1,555,105 and 1,267,680 in May, June and July, respectively. The calculated cost-benefit ratios in May, June and July were 1.59, 1.51 and 1.46, respectively. The hatchery got the highest net profit of BDT (Bangladeshi Taka) 1,041,906 in May due to the highest production and higher price of spawn, and the lowest profit of BDT 546,176 was obtained in July. So, May was found to be the peak breeding month of Ma Fatima Hatchery. The estimated cost-benefit ratio indicated that the spawn production through induced breeding techniques was profitable for the hatchery owners.

This study was conducted to assess the aquaculture potential of the freshwater prawn Macrobrachium rosenbergii (de Man, 1879) with the Indian major carps (Catla, Catla catla; Rui, Labeo rohita and Mrigal, Cirrhinus mrigala) and silver carp, Hypophthalmichthys molitrix in northwestern Bangladesh. Further, the effect of the culture system on overall production and economic feasibility was evaluated. A 3×2 (treatment×replicate) experimental setup was conducted using six earthen ponds measuring 100 m2 each for a culture period of six months from September, 2007 to February, 2008. The treatments were as follows: T1 was stocked with only carps (catla, rohu, mrigal and silver) at the 3000 (catla), 2000 (ruhu), 3000 (mrigal) and 2000 (silver) ha-1; T2 and T3 were stocked with catla and silver carp were 3000 and 2000 ha-1, respectively; and additionally M. rosenbergii (juvenile) was stocked at 15000 and 20000 ha-1 in T2 and T3, respectively. All the ponds were subjected to the same fertilization treatment. Fish were fed twice per day at a rate of 5-12% of the prawn and fish body weight. The net weight gain of catla and silver carp were 69.08±11.63 and 108.67±15.00 g in T1, 61.76±12.58 and 98.80±17.05 g in T2, while 58.11±12.51 and 93.09±14.84 g in T3, respectively. The mean individual weight of harvested prawn was significantly higher in T2 (14.61±02.06 g) than T3 (14.04±01.83 g) (P<0.05). Also the survival rate of prawn was higher in T2 (74.15%) than T3 (69.25%) (P<0.05). The net production of prawn was higher in T3 (1141.28±46.35 kg ha-1) than T2 (964.54±25.53 kg ha-1), but the specific growth rate was significantly higher in T2 (2.07%) than T3 (1.99%) (P<0.05). Higher profit was obtained in T3 (35682.18 Tk ha-1) than T1 (8537.53 Tk ha-1) and T2 (30801.56 Tk ha-1); however, cost-benefit ratio (CBR) was significantly higher in T2 (3.19) where stocking densities of prawn was 15000 ha-1 than T1 (2.92) and T3 (2.47). The results of this experiment indicate that the polyculture of the freshwater prawn with the Indian major and Chinese carp present a more profitable venture which is more economically feasible than the monoculture of the freshwater prawn.DOI: http://dx.doi.org/10.3126/on.v9i1.5735

As microalgal blooms are very common and making serious problems in water bodies throughout Bangladesh, an investigation was carried out to see the composition and succession of noxious blue-green algae in pangasiid catfish (Pangasianodon hypophthalmus) ponds. During the course of the study, 20 species of Cyanophyceae were recorded, and among them Microcystis aeruginosa was the most abundant compared to other species. Significant occurrence of Microcystis viridis was also observed. Efforts were made to study certain physico-chemical factors and their influence on the composition and seasonal abundance of these species. Peak abundance of M. aeruginosa was observed from July to August. Moderately higher water temperature, lower rainfall and NO3-PO4 enrichment increased the biomass of both M. aeruginosa (168.72×103cells/L) and M. viridis (8×103cells/L) in the experimental ponds. Higher feeding rate in monoculture of pangasiid catfish (P. hypophthalmus) made the ponds hyper nutrified by unutilized feed and fish excreta that supported the higher abundance of these Cyanophyceae. In composite culture ponds, silver carp (Hypophthalmichthys molitrix) effectively grazed down the microalgae and as a result, algal bloom was not noticed.
