Performances of Bottom Dwelling Carpsin Polyculture Ponds under Drought Prone Barind Area of Bangladesh
Importance of pond based carp polyculture as a popular technique for fish production in Bangladesh is well documented [1]. It has further potentials to improve the livelihood of the poor and marginal peoples [2]. Potentials of pond based fish production towards livelihood improvement are also explored well by Hossain et al. [3] for Barind area having characteristic soil-water qualities like low...
متن کاملEffects of co-cultured common carp on nutrients and food web dynamics in rohu aquaculture ponds
Using the common carp Cyprinus carpio L. in polyculture ponds to increase both phytoand zooplankton availability has become a popular practice for the cultivation of plankti vorous fish, such as rohu Labeo rohita Hamilton. However, the dynamics of how common carp influences the environment and ecology in polyculture ponds are unclear. In the present study, the effects of various stocking densit...
متن کاملMonitoring meteorological and agricultural drought dynamics in Barind region Bangladesh using standard precipitation index and Markov chain model
The Barind region of Bangladesh suffers from frequent drought due to poor and delayed rainfall in pre monsoon and monsoon season. In the present study details analysis of rainfall data has been carried out for the years 1971-2010. Two well known drought indices, Standard precipitation index (SPI) has been used to evaluate the precipitation deficit, and Markov chain model used to quantify the dr...
متن کاملImpacts of inclusion of column feeder rohu (Labeo rohita) at different stocking densities on growth, production and environment in freshwater prawn-carp-mola polyculture system
The research investigated the impacts of inclusion of column feeder rohu (Labeo rohita) on growth and production in freshwater prawn-carp-mola polyculture system for a period of 172 days. Four stocking densities of Rohu were maintained as 500, 1,000, 1,500 and 2,000 ha -1 in treatment R500, R1000, R1500 and R2000, respectively in triplicates. All ponds each 120 m 2 were stocked with juvenile fr...
متن کاملInfluences of radiation on carp from farm ponds in Fukushima
A massive release of artificial radionuclides from the Fukushima Dai-ichi Nuclear Power Plant caused radioactive contamination of farms as well as of aquatic products. Carp in small ponds in the highly radiocontaminated area of Iitate Village, Fukushima Prefecture, have been confined to the ponds since the accident, and it is thought that the carp may have suffered health issues as a result. Th...
