Occurence and Abundance of some Copepods in a Fish Pond in Rajshahi, Bangladesh in relation to the Physico-Chemical Conditions

Abstract

An investigation was carried out to find out the occurrence and abundance of copepods in relation to physico-chemical parameters in a fish pond within the Rajshahi University Campus, Rajshahi, Bangladesh from December, 2006 to September, 2007. A total of 5 genera of copepods of which 2 species belong to Cyclops were identified. Highest density of copepods (768 units/l) was observed in May 2007. Seasonal succession of copepods showed the most abundance in spring, followed by winter, summer and autumn. Correlationship between different physico-chemical parameters and copepods were also analyzed. Key words: Copepod occurrence, physico-chemical parameters, fish pond.   DOI:10.3329/jbs.v16i0.3752 J. bio-sci. 16: 115-119, 2008
