Effects of Stocking Density on Growth and Production Performance of Indigenous Stinging Catfish, Heteropneustes fossilis (Bloch)

Abstract

An on-farm experiment was undertaken in nine earthen ponds to evaluate the growth and production potentials of stinging catfish shing, Heteropneustes fossilis for the period of six months from March to August 2010. Three stocking densities such as 1,25,000 (T1), 1,87,500 (T2) and 2,50,000 ha-1 (T3) were tested with three replications each. Fish were fed with commercial pelleted feed containing 35% crude protein. After six months rearing, the mean harvesting weights of shing were 69.42±6.20, 58.74±3.85 and 49.50±4.52g in T1, T2 and T3, respectively. Significant (P<0.05) highest mean harvesting weight was found in T1. The best survival was found in T1 (87%) among the treatments. The calculated mean production of shing (H. fossilis) in three treatments such as T1, T2 and T3 were 7549±52, 9031±71 and 8786±60 kg ha-1, respectively, which were significantly different (p<0.05) from each other.

Culture of indigenous catfish Shingi, Heteropneustes fossilis (Bloch, 1794), with available low cost formulated feed in earthen ponds of Bangladesh

“…The mean value of dissolved oxygen in water varied from (4.47 ± 0.10) (T 3 ) to (4.53 ± 0.08) mg/L (T 2 ) in the present study. This finding strongly agreed with Kohinoor et al [20] who measured the dissolved oxygen of 4.23 to 5.32 mg/L in H. fossilis culture ponds.…”

Impact of live tubificid worms on the growth and survival of Heteropneustes fossilis (Bloch, 1794) reared in tanks

“…The percentage of survival as recorded in the present study was similar as reported by Kohinoor et al, (2012).…”

“…Considering its status it is essential to develop a suitable culture technique in Bangladesh. However, very little published literature are available on growth and production of stinging catfish in pond, cistern and net cages in Bangladesh (Haque et al, 1988;Khan et al, 2003;Narejo et al, 2005 andKohinoor et al, 2012). This is an excellent fish for culture in derelict water bodies as it is able to live in poorly oxygenated water due to its capacity to exchange via accessory respiratory organ (Singh and Hughes, 1971).…”

Application of Inorganic Fertilizers and Organic Manures on the Production of Autotrophic Plankton in Madhupur Tract Soil Contained Miniature Tank

“…Similar results obtained by Dhawan and Kaur (2002); Okbah and Gohary (2002). Kohinoor et al (2012) reported that the similar range of pH value even suitable for catfish culture ( , 1997). The studied values were lower DO in the MCRT-2 and 3 in the later summer to early part of monsoon may be the result of decomposition of plankton and autochthonous organic maters.…”
