A study on the abundance of zooplankton of a culture and a non-culture pond of the Rajshahi University campus

Zooplankton constitute important food item of many omnivorous and carnivorous fishes. The study was conducted with an aim to study the zooplankton production including physico-chemical parameters with an emphasis to the existing management practices taken by the operators. The study was carried out in a culture and a non-culture pond of Rajshahi University campus was carried out from September, 2004 to February, 2005. Monthly fluctuations of some physico-chemical parameters were noted. The ponds showed alkaline in nature with moderate bicarbonate alkalinity. Diurnal change of water temperature, free CO2 and dissolved Oxygen were also studied. Four groups of zooplankton were identified, of which copepods (1260 units/l and 973.33 units/l in pond-1 and pond-2 respectively) were most dominant. A total of 9 genera of zooplankton were identified of which Cyclops (68.25% and 60.28% of total copepods) was most abundant in both ponds. Total zooplankton showed positive correlation with pH, carbonate alkalinity (CO3) and bicarbonate alkalinity (HCO3) in both ponds and DO, carbon dioxide (CO2) in pond-1. Present findings indicated that the culture pond showed better result than that of the non-culture pond regarding zooplankton production. Key words: Zooplankton, culture pond, non-culture pond, physico-chemical parameters. Â doi:10.3329/ujzru.v27i0.1951 Univ. j. zool. Rajshahi Univ. Vol. 27, 2008 pp. 35-41

Composition and abundance of zooplankton in a polyculture pond was studied during June 2003 to May 2004. A total of 33 major species of zooplankton including 11genera of Rotifera, 4 of Copepoda, 4 genera of Cladocera and 2 genera of Protozoa were identified. The monthly abundance of zooplankton varied form 4228 indiv/l in October 2003 to169 indiv/l in January 2004. Among the total zooplankton, Rotifera comprised of 71.07%, Copepoda comprised of 12.49% Nauplii comprised of 11.96%, Cladocera comprised of 1.49% and Protozoa comprised of 2.99%. Water temperature (r = 0.18), free CO2 (r = 0.40), TDS (r = 0.14) and water depth (r = 0.55) showed positive correlation with zooplankton but air temperature, pH, dissolved O2, total hardness and ammonia showed negative correlation (the coefficients being -0.18, -0.05, -0.25, -0.38 and -0.11 respectively) with the occurrence of zooplankton. The average growth of fishes and zooplankton showed positive correlation in all cases but the relations were insignificant when tested statistically.Bangladesh J. Zool. 42(1): 67-76, 2014

Study was conducted to determine the physico-chemical parameters of water of three different lakes in Jahangirnagar University campus from March to November, 2013. The selected parameters were water depth, water temperature, conductivity, transparency, pH, dissolve O2, free CO2, total alkalinity, hardness, sulfate and water color. Water depth fluctuated from 140 cm to 385 cm, temperature ranged from 250C to 310C, conductivities ranged from 627 ?S/cm to 1544 ?S/cm, transparency from 22 cm to 87 cm, considerable variation of water colors were found and pH ranged from 6.4 to 7.5 without having any significant fluctuation. Dissolve oxygen (DO) ranged from 2.7 mg/l to 7.6 mg/l, carbon dioxide level ranged from 16 mg/l to 62 mg/l, total alkalinity and hardness were ranged from 43 mg/l to 92 mg/l and 63 mg/l to 134 mg/l, respectively with slight variations in different lakes in different months. During the study period, all the spots showed minimum fluctuation of physico-chemical parameters from the normal range without having some exceptions.Bangladesh J. Zool. 43(2): 239-250, 2015

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.
