An overview of the traditional rice-prawn-fish farming in Kalia of Narail district, Bangladesh

Abstract

This study was conducted in Narail district, Bangladesh between January and June, 2012; with a view to describing the status of rice- prawn-finfish based aquaculture practices. Average area of plots was 0.55±0.44 ha, of which mean ditch area was 4.35±2.02% of total land. All farmers dry their plots and made renovation prior to start of a new growing season followed by liming and fertilization. No standard stocking density was maintained, prawns were stocked at 15895 PL/ha, whereas fin fishes at 1551 seeds/ha. Commercial feed was applied in all the plots. Production of prawn, stocked and non-stocked finfishes were found 380.34±155.25 kg/ha; 713.65±352.99 kg/ha and 51.73±24.55 kg/ha respectively. Average cost and income for fish culture were 120514.07±36758.35 BDT/ha and 232497.48±76594.80 BDT/ha respectively. Average rice production was 4229.78±856.71 kg/ha. Low growth and high mortality of PL; scarcity, high and uprising price of feeds; and floods were identified as the major problems.

Environment and fish fauna of the Atrai River: global and local conservation perspective

“…It is speculated that this popular aquaculture species has already been established itself into the natural waters of Bangladesh (Rahman 2007) and the present record indicates justification of such assumption. This species is commonly found all over the country and also a popular species not only in aquaculture ponds but also in integrated fish culture in rice fields (Galib et al 2013b). However, this was not the first record of H. molitrix in the natural waters of Bangladesh.…”

Effects of Beta vulgaris powder on growth and survival of common carp Cyprinus carpio

“…Nowadays, common carp is considered one of the most important species in Iran (Ghaderi Ramazi et al 2012) and outside (e.g. Mohsin et al 2012;Galib et al 2013) due to its high resistance to environmental fluctuations and the use of a wide range of available foodstuffs. This species is cultivated in almost all provinces of Iran's aquaculture industry due to its unique breeding characteristics.…”

Rigor index, fillet yield and proximate composition of cultured striped catfish (Pangasianodon hypophthalmus) for its suitability in processing industries in Bangladesh

“…The increasing cost of feed stuffs in animal production have been identified as a serious impediment in meeting the demand for animal protein particularly in developing countries (Adejinmi et al 2000;Hossain et al 2009;Mohsin et al 2012aMohsin et al , 2012b. However, the everincreasing cost of animal feeds makes it necessary to explore the use of alternative feed ingredients that are cheaper, locally available and of low human preference (Agbede et al 2002;Tuleun et al 2009;Kamal et al 2010;Galib et al 2013;Asadujjaman and Hossain 2016) such alternatives include the uses of edible leaves (vegetables). Vegetables are rich sources of vital ingredients in healthy and balanced human and animal diets without quantitative restriction (Aletor and Adeogun 1995;Okoli et al 1998;Osuagwe 2008).…”
