In order to understand the present status of hatcheries, questionnaire interview and participatory rural appraisal tools were used in North-west Fisheries Extension Project (NFEP), Parbatipur during the period from July to December 2015. There are two hatcheries in NFEP, Parbatipur- a carp hatchery and a prawn hatchery. The production of spawn was around 611 kg in the year 2015. According to the target hatchery manager collected brood fish from rivers and other sources which he maintained in their brood stock ponds with proper management. The hatchery manager maintained proper age and weight of broods for spawning and followed the guideline of hatchery operation so that the quality of spawn and fry were good. It was found that the hatcheries produced fish seed of a variety of species such as Indian major carps, carpio, sarpunti, silver carp, grass carp, magur, shing as well as freshwater prawn. The hatchery production activities took place starting from February and continued up to September. The quantity of fish seed produce varied from 25 to 75 kg per hatching cycle depending on size and facilities of hatcheries. The price of fry in NFEP was being fixed by the hatchery manager. However, the price variation was seen due to seasonal variation, species and demand. The average price of fish seed was highest in monsoon and lowest in winter. A number of middlemen were involved in the fry marketing channel of NFEP at Parbatipur. They were responsible for increasing the price of fry at each stage of marketing channel.Asian J. Med. Biol.

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

Halda is a unique resourceful tidal river of Bangladesh, where Indian major carps (Catla catla, Labeo rohita, Cirhinnus mrigala, and Labeo calbasu) spawn from April to June. Ecological conditions are auspicious from time immemorial which serves as a natural breeding ground in the world. The present study was conducted over the period of January-June 2017 to identify the main species of Zooplankton fauna and also fi nd out the dominancy of the highest plankton groups in the lower Halda River. A total of 3 major zooplankton groups-Copepoda, Rotifera and Cladocera were identifi ed during the six months period. A total of 35 species under 4 family showing the dominancy for the class Rotifera consisting of 7 genera were recorded from fi ve sampling sites. The lowest group was Cladocera consisting of 5 genera. The composition and dominance of the zooplankton community among fi ve different sites in the lower Halda River showed some close inter-relationships. The present study suggests for conducting further research to know the overall conditions and to make a complete list of available zooplankton fauna that exert impact on the water quality of the Halda River.

The major source of carp seed in India is from induced breeding and most seed farms in Karnataka State use ovaprim for commercial production of fish fry. The present study was conducted to investigate the possibility of employing a combination of buserelin (an analogue of mammalian LHRH) and domperidone (a dopamine antagonist) for the induced spawning of the three Indian major carps, viz. catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus mrigala). All the three species could be successfully induced bred using a combination of mLHRH-a and domperidone (DOM) through a single injection. Important aspects of induced spawning such as breeding response, fecundity, latent period, fertilization rate and quantity of spawn obtained with mLHRH-a +DOM were compared with those of sGnRH-a and DOM combination (ovaprim), a widely used fish spawning agent in India. The breeding response of females of all the three species treated with mLHRHa+DOM was 100%, while it varied between 86 and 100% for sGnRH-a+DOM treated fish. The fecundity, fertilization rate and quantity of three-day-old spawn realized for the former combination were equal or better than those obtained for the latter. Among the different doses tested, 0.8, 0.7-0.8 and 0.7 mlxkg-1 body weight (b.w.) of female produced consistently good results in catla, rohu and mrigal, respectively. Lower doses (0.4-0.5 mlxkg-1 b.w.) also led to the mass spawning of mrigal, with fertilization rate ranging between 89 and 93%. In all the trials, the males received either sGnRH-a+DOM at 0.1-0.2 mlxkg-1 b.w. or mLHRH-a+DOM at one-third of the dose given to the female. The quality of carp seed produced through mLHRH-a+DOM was good and comparable to that obtained with sGnRH-a+DOM and it is more economical than the former spawning agent.

Fish ponds operate as an open ecological system where natural and technological processes are built on one another and are implemented in a non-separable way. Pond fish farms contribute to preserve biodiversity. In both districts the composite fish culture technology is commonly followed for fish farming with six species combination i.e. Indian Major Carps (IMC) i.e. Catla, Rohu and Mrigal (Nain) and Exotic Major Carps (EMC) i.e. Silver carp, Grass carp and Common carp. There are 14 blocks in Basti district in which 3848 number of ponds are found. These ponds cover 1040.42 ha of water spread area. There are 16 blocks in Gonda district. The number of ponds is 4471 with water spread area of 3706.86 ha. The total productions of fishes are 1800 ton/year in Basti district while 3850 ton/year in Gonda district. The average productions are 2800 kg/ha/ year and 3000 kg/ha/year in Basti and Gonda districts, respectively. The data indicated that the Gonda district have more potential in fish production compared to Basti district. The maximum ponds were of less than 1 hectare in both districts. The respondents were 68% in Basti district and 76% in Gonda District. 82% and 70% respondents have leased pond in Basti and Gonda districts, respectively. Gonda district has more potential for fishing in future.

A study was conducted to analyze the status of fish marketing system in Parbatipur upazilla of Dinajpur district in the northwest region of Bangladesh during December 2010 to May 2011. The marketing chain from farmers to consumers in all the three fish markets was found to pass through a number of intermediaries. Four types of marketing channel were identified. The average marketing cost of retailer was 3.69 Tk/kg. The net marketing margin of the retailers for Indian major carps and Exotic carps were 8.42 and 19.17 Tk/kg, respectively. Seasonal variations in prices were observed with the highest in summer (March to May) and the lowest in winter (December to January). A number of constraints were identified. The infrastructure, transportation and packaging facilities were not satisfactory and sufficient in all the three fish markets under survey.

Abstract Genetic and non-genetic aspects of seed quality are discussed. A system of seed production for Indian major carps and Chinese carps, which require sophisticated hatchery facilities, has been established in the country. However, there is concern about deterioration of the quality of broodstock in current hatchery management. Self-recruiting species like tilapia, common carp and silver barb can be bred in decentralized systems but the absence of a regular supply of quality broodstock may lead to poor seed quality due to poor farm management at homestead level.

Present study investigated the shelf life of fermented silage prepared from dressing waste (gut and gills) of Indian major carps and the effect of different concentrations of jaggery as carbohydrate source, on the biochemical and microbiological changes in the silage. Fermented silage was prepared using jaggery at 10% w/w (F1) and 20% w/w (F2) concentrations. F2 had a lower crude fat and ash content. The lowest pH attained was 4.11 and 4.02 in F1 and F2 respectively by the end of 15 days. Significantly higher (p<0.05) concentration of total volatile base nitrogen (TVB-N) was observed in F2 from the 30th day of storage. The rate of auto-oxidation was also significantly higher in F2 throughout the storage period of 60 days. Total plate count (TPC) of bacteria in F1 and F2 reduced significantly till the 15th day of storage. At the end of 60 days of storage, pH reached 5.55 and 5.67 in F1 and F2 respectively, thereafter the silage was considered spoiled. The study indicated that fermented fish silage prepared from viscera and gills of Indian major caps remained shelf worthy for a period of 60 days and the use of jaggery at concentrations higher than 20% (w/w) would not be viable as it led to faster spoilage rate and increased cost of production
