Constraints and prospects of carp production in Rajshahi and Natore districts, Bangladesh

Abstract

: This study was conducted in Rajshahi and Natore districts of northern area of Bangladesh for a period of three years (2007 to 2009). One hundred carp ponds were selected randomly and fish farmers were interviewed to reveal the existing constraints and prospects. Ten percent farmers reported multiple ownership as a problem and 16% farmers stated that lease value of pond is too high which reducing their profit level. Lack of quality fish seeds was reported by 33% farmers which results in low growth and high mortality of fishes. Nine percent carp farmers reported that inorganic fertilizers were not giving expected performances. Thirty three percent carp farmers failed to apply required inputs in due time due to lack of sufficient credit. Plankton bloom was recorded in 18% ponds. Three percent fish farmers were found to be affected by flood and drought. Eight percent farmers reported non-severe attack of disease. Fish poaching and poisoning were revealed as major constraints. Thirty six percent farmers mentioned lack of technical supports. Due to found constraints, the farmers failed to use inputs and experiences properly resulted in unsatisfactory fish production (3598.72±785.83 kg/ha/yr) to the carp farmers. Further research efforts are recommended to assess the specific impacts of recorded constraints on fish production.

Fish farming status at Sreemangal upazila of Moulvibazar district, Bangladesh

“…Likewise, the average production was 2,900 kg/ha/yr in Shahrasti, Chandpur (Pravakar et al, 2013), 2,925 kg/ha/yr in Gazipur district (Rahman, 2003) and also the same carp production was found in Bhaluka, Mymensingh (Kamruzzaman, 2011) and 2,940 kg/ha/yr in Moulvibazar (FRSS, 2015). On the other hand, mean (±SD) fish production was found 3,598.72±785.83 kg/ha/yr in carp polyculture of Rajshahi and Natore districts (Mohsin et al, 2012) and 3,743 kg/ha/yr in Mymensingh (Biswas, 2003). The annual production varies because of differences in pond size, depth, categories, feed, seed, other inputs and management practices.…”

Influence of Stocking Density on Growth Performance of Labeo bata in Cage at River Padma, Rajshahi, Bangladesh

“…The minimum value was recorded in T 2 whereas the maximum value was recorded in T 3 . DoF [8] reported that in a water body the suitable range of DO for fish culture would be 5-8 mg/1. Asadujjaman et al [22] observed that dissolved oxygen ranged between (5.45 to 7.78 mg/1) during their experiment in BAU campus, Mymensingh.…”

“…In Bangladesh, culture-based fisheries and smallscale aquaculture are often constrained by the lack of suitably sized seed stock. Although there is a large quantity of fry of cultured species in particular carp species produced in Bangladesh, fingerling production has lagged behind due to economic and land constraints [8]. Promoting cage culture could meet the demand of land for fish farming.…”

Optimization of dietary protein level for good aquaculture practice based carp fattening in ponds under drought prone area of Bangladesh

“…Carp contributes 52.06% of the total pond production in Bangladesh (FRSS, 2020). Aquaculture, especially carp culture, is essential for supplying nutrition, income and employment in Bangladesh (Mohsin et al, 2012). It has the advantages of easy access and developed market demands over the other aquaculture practices.…”
