Raised stocking materials, fingerling of Indian major carp seeds (Catla catla, Labeo rohita Cirrhinus mrigala) in pens, installed in two floodplain wetlands of Assam viz. Goruchora (Golaghat district) and 46-Morakollang (Morigaon district). The pens were stocked at 30,000 fry•ha-1, in a ratio of 3:2:1 of C. catla, L. rohita and C. mrigala fry, respectively. The average initial length and weight of fry at the time of stocking for C. catla, L. rohita and C. mrigala were 5.45 cm (1.80 g), 4.51 cm (1.15 g) and 4.65 cm (1.12 g), respectively. The fish stocks inside the pens were given supplementary feeds, mustard oil cake and rice polish (1:1) at 5% body weight. The pens were harvested after a rearing period of 145 days with an average growth of C. catla (19.0 cm, 85.1 g), L. rohita (15.8 cm, 52.8 g) and C. mrigala (15.8 cm, 42.9 g) in Goruchora wetland, while in 46- Morakollang wetland it was recorded as 17.0 cm (63.8 g) for C. catla, 15.4 cm (55.9 g) for L. rohita and 14.0 cm (41.5 g) for C. mrigala for further grow-out in the lakes proper. During the period of experimentation, the fluctuations in water quality parameters like water temperature (17.6-29.0o C), transparency (72-102 cm), dissolved oxygen (3.60-16.50 mg•l-1), pH (7.12-9.53), total dissolved solids (46.6-111.3 mg•l-1) and specific conductance (102-232 µS•cm-1) were monitored, too. The production in terms of fish biomass (fingerlings) was estimated at 2106 and 1780 kg•ha-1 in Goruchora and 46- Morakollang wetlands, respectively. The cost-benefit ratio was calculated as 1.40 (Goruchora) and 1.77 (46-Morakollang), which can be considered as significant, economically.

Lack of quality carp seeds is one of the major problems for fish production in Bangladesh. This experiment was conducted during July to December 2013 to study the production and economics of carp polyculture using wild and hatchery produced seeds in ponds in Faridpur district, Bangladesh.  Seeds of native major carps (NMCs) (Catla catla, Labeo rohita and Cirrhinus mrigala) and non-native carps (NNCs) (Hypophthalmichthys molitrix, Ctenophryngodon idella, Aristichthys nobilis and Cyprinus carpio) from four different sources were tested in feed and fertilizer based polyculture ponds under controlled mesocosm trials with four treatments (T1–T4), each with four replications. Combination, weight and density of the stocked species were same for all the treatments. Water quality parameters were monitored monthly and mean values were found within suitable range for fish farming. Mean final weight, weight gain, specific growth rate and yield of L. rohita, C. catla and C. mrigala were found significantly (P < 0.05) higher with treatment T1, T3 and T2 respectively. Treatments T1, T2 and T3 varied more significantly (P < 0.05) than treatment T4 for total fish yield and cost benefit ratio.  Polyculture of wild sourced NMCs and hatchery produced NNCs were found more profitable than aquaculture of hatchery produced NMCs and NNCs.

An investigation was made on the ecto-parasitism of juvenile carps of Mymensingh region.  Eight  farms, four Government (Govt.) and four Private (Pvt.) fish farms were investigated for Indian major carps(Catla catla, Labeo rohita and Cirrhinus cirrhosus)  (Catla, Rui and Mrigal)  during  June, 2010 to May, 2012. Monthly samplings were carried out with 5 fish from each species and each farms. Altogether 2880 fish hosts were examined of which 1674 were found to be infested with different groups of parasites during the study period. The ectoparasites were very common in gill, skin, mouth cavity, muscle, base of the pelvic, pectoral, anal, caudal fin and body surface of all fishes. Eleven species of protozoan, thirteen species of  monogeneans and two species of argulus were recorded. The risk of being infestation by parasites in carps significantly (p<0.001) increased when the water quality parameters were deteriorated. Prevalence (%), mean intensity and abundance were found to be species specific and also varied with seasons and management systems practiced by different farmers. Prevalence (%) of ecto-parasites in carps was significantly (p< 0.001) higher in Pvt. farm than that of Govt. farms and was significantly (p< 0.01) higher in rainy season. Rui was more susceptible than Catla and Mrigal.

A study was conducted to investigate the infestations of monogenetic trematodes of juvenile carps of Mymensingh region. A total of eight (8) farms, four Government (Govt.) and four Private (Pvt.) fish farms were investigated of Indian major carps - Catla (Catla catla), Rui (Labeo rohita) and Mrigal (Cirrhinus cirrhosus) during June, 2010 to May, 2012. Monthly samplings were carried out with 5 fishes of each species and each farm. Altogether 2880 fish host were examined of which 1424 hosts were found to be infested with monogenetic trematodes of which 626 from Govt. and 798 from Pvt. farms. The monogeneans were very common in gills of all fishes. Water quality parameters were taken and management practices were also noted. The risk of infestation by monogeneans of carp significantly (p<0.001) increased when the water quality parameters were deteriorated. Prevalence (%), mean intensity and abundance were found to be species specific and also varied with seasons and management systems practiced by different farmers. Prevalence (%) of monogeneans in carps was significantly (p< 0.001) higher in Pvt. farm than that of Govt. farms. The prevalence (%) of monogeneans were significantly (p< 0.01) higher in rainy season than dry season. Mrigal was more infected by monogeneans followed by Catla and Rui.Res. Agric., Livest.

The study was conducted at Ma-Fatema Fish Hatchery in Jessore from January to March, 2016. The present study was emphasized on water quality parameters, feeding management and cost- benefit analysis. The water quality parameters temperature (0C), pH, dissolved oxygen (DO) (mg/l) and transparency (cm) were measured by Celsius thermometer, pH meter, DO meter and secchi disk, respectively. The proximate composition of feed ingredients was determined by the Association of Analytical Chemists, 1980. Brood fishes were reared all year round in the brood ponds by supplying formulated feeds. Temperature was 19oC -26°C in brood ponds and 18oC-24oC in hatching jars; pH was 6.93–7.87 in brood ponds and 6.79-7.54 in the hatching jars; dissolved oxygen was 4.8-6.3 mg/l in brood ponds and 4.8-6.7 mg/l in hatching jars; transparency was 14-18 cm in the brood ponds. The percentage of farm made feed was protein (27.76%), lipid (4.9%), CHO (18.62%), ash (11.31%), fiber (6.4%), moisture (31.01%). The cost benefit ratios were 1.54, 1.32 and 1.23 and net profits were BDT 49911.67, BDT 24816.67and BDT 16366.67 respectively in January, February and March. Management of brood fish by providing quality feed and physico-chemical parameters of water were maintained in according to scientific procedure. Cost-benefit ratio of the hatchery in common carp production was satisfactory.Asian J. Med. Biol. Res. September 2016, 2(3): 414-421

This study was aimed to evaluate the efficiency of three protein level feeds on the fingerlings production of riverine endangered Notopteruschitala (Hamilton, 1882) for a period of two months in ponds. Chital fry (Initial wt, 5.6±0.19 g) were randomly stocked at the rate of 7410 per hector. Feeding trials were conducted under 3 treatments (T1: feed contains 35% protein, T2: feed contains 30% protein, T3: feed contains 25 % protein) each with 3 replications. No significant (P<0.05) difference was observed for all the water quality parameters among the treatments. A suitable range of water quality parameters (temperature, water transparency (cm)), dissolved oxygen (mg/l), pH, alkalinity (mg/l), ammonia) were recorded with the environment of experimental ponds. The treatment had significant effects on weight gain, ADG, SGR among treatments. Highest weight gain (19.31 ± 0.23 g) was observed in T1, lowest (13.96 ± 0.15 g) in T3. SGR (1.65±0.02) and ADG (0.18±0.005) were significantly (P<0.05) highest in T1 followed by T2 and T3. The N chitala exhibited highest survival rate (96.66%) in T1 than T2 followed by T3 (88.89 %). The best FCR value (3.02±0.09) was recorded in treatment T1 with 35% protein contain feed. Relatively, highest benefits (138690±175.36 BDT/ha) were found from treatment T1 compared to other treatments. Similarly, the cost benefit ratio was highest in T1 (1:1.23) and lowest in T3 (0.95). Findings indicated that treatment T1 (35% protein containing feed) was found best in terms of growth, production and economics of N. chital for fingerling production in ponds. Res. Agric., Livest.

Pen culture for in situ raising of stocking material was conducted in Sareni Jheel, located in the Rae Bareli District of Uttar Pradesh. Sareni Jheel, being rich in organic carbon (4.5%) and nutrients, higher values of silt (29%) and clay (15%) were recorded. Rich oxygen levels, alkaline pH, high organic matter, moderate to high chemical parameters suggested moderately productive nature of this wetland. Pen with high-density polyethylene (HDPE) net was installed in an area of 0.1378 ha and stocked with advanced fry of the Indian major carps, rohu Labeo rohita and catla Catla catla in the ratio of 1:1 @ 25 nos. m-2. No significant changes in water quality parameters were noticed within and outside the installed pen. Mean weight at stocking of rohu and catla was 2.88±1.41 g and 2.1±1.16 g, which increased to 57.2±13.84 g and 67.38±25.79 g respectively, in 120 days. The average feed conversion ratio (FCR) recorded was 1.08 with overall survivability of 69.52% in rohu and 74.74% in catla. Benefit-cost ratio and return on investment were calculated as 1.69 and 0.69, respectively. Intervention through pen culture resulted in the increase in fish productivity of Sareni Jheel from 310 to 833 kg ha-1.

An 8 months feed demonstration program was conducted in the ponds of Ramakrishna Mission, Belur Math, West Bengal, India. The program aimed at providing hands-on training to trainees at Samaj Sevak Sikshan Mandir (SSSM) on farm-made feed formulation and use in aquaculture. Two ponds were selected, one at Shilpamandira of 0.1 h and fish were fed Feed-1, and another of 0.08 h at Samaj Sevak Sikshan Mandir (SSSM) and fed Feed-2. Indian major carps, Catla catla (catla) and Labeo rohita (rohu) were stocked at 4500 fish ha-1. The stocking size of rohu was 80-90g and of catla was 220-245g. Locally available low cost feed ingredients, rice bran, mustard oil cake, til oil cake and linseed oil sludge were used to formulate and prepare two farm-made mash feeds (Feed-1 and Feed-2). The fish were fed at 2% of total fish biomass in the ponds and were fed through bag feeding. At the end of the study rohu grew to 1.07 kg and catla to 1.6 kg in Shilpamandira pond (Feed-1), and rohu to1.5 kg and catla to 2.2 kg in Samaj Sevak Sikshan Mandir pond (Feed-2). The net production of fish was 4.9 and 6.8 t ha-1 for 8 months with Feed-1 and Feed-2, respectively. Dietary inclusion of linseed-oilsludge significantly increased the PUFA content in Indian major carps. The feed cost was substantially reduced by replacing mustard oil cake with til oil cake and incorporation of linseed oil sludge, a very low priced ingredient.SAARC J. Agri., 15(2): 45-55 (2017)

Open aquatic system such as beel is an important freshwater resource for agriculture and aquaculture.This study was conducted (July-December 2014) to describe the beel aquaculture management practices in the Hagla Beel at Bagmara upazila under Rajshahi district.The Beel fish farming area was 20.25 ha and irregular in shape with average depth 1.5 m. During the study period, the measured water quality parameters of the beel were within the suitable range for aquaculture. Eight genera of phytoplankton and eight genera of zooplankton were identified from the beel water body. Four native and 4 exotic fish species with sizes ranging from 0.15-1.11 kg were stocked for growing in the beel. At the end of culture period, the production of fish was 2,622.15 kg/ha and cost-benefit ratio (CBR) was 1:1.42. Environmental problems such as increasing of water temperature and decreasing of water level during summer, and parasitic diseases were some of the risks in beel fish farming system. The results of this study should be useful for beel aquaculture, and for the farmers and resource manager for harnessing maximum benefits from the beel resources in Bangladesh.

The study was carried out to find the prevalence of ectoparasites in carp species specifically Indian Major Carps (IMC) during the post monsoon season (November’16 to March’17). Four groups of ectoparasites viz. myxozoan, ciliophoran, monogenean and crustacean were recorded from approximately 500 number of  carp species like, Labeo rohita, Catla catla, Cirrhinus mrigala and Labeo calbasu collected from different ponds of selected blocks of South 24 Parganas district of West Bengal. The highest prevalence (64.76%) of infestation had been recorded by Myxozoans and the lowest was by Monogeneans (4.79%). The highest and lowest ectoparasitic prevalence in carp was observed in L. rohita (32.88%) and C. catla (27.28%). At the end of this experiment it was concluded that sudden changes in water quality parameters, over stocking, lack of management practices and some other aspects were the key factors for disease occurrences in this post monsoon season.

Studies were conducted to investigate the infestations of Argulus of juvenile carps of Mymensingh region.  A total of 8 farms, four Government (Govt.) and four Private (Pvt.) fish farms were investigated Indian major carps - Catla (Catla catla), Rui (Labeo rohita) and Mrigal (Cirrhinus cirrhosus) during June, 2010 to May, 2012. Monthly samplings were carried out with 5 fish from each species and each farm. Altogether 2880 fish host were examined of which 940 hosts were found to be infested with Argulus during the study period. The Argulus were very common in body surface, base of the pelvic, pectoral, anal, caudal fin, muscle and mouth cavity of all fishes. Water quality and management practices were recorded in different farms. The risk of infestation by Argulus in carps significantly (p<0.001) increased when the water quality parameters were not maintained the optimum level. Prevalence (%), mean intensity and abundance were found to be species specific and also varied with seasons and management systems. Prevalence (%) of Argulus in carps was significantly (p< 0.001) higher in Pvt. farm than that of Govt. farms. The   prevalence (%) of Argulus were significantly ( p< 0.01) higher in rainy season. Rui was more susceptible than Catla and Mrigal by Argulus.
