In order to contribute to the improvement the production of fry through larval feeding, a study on the effect of doses of chicken manure on the structure and dynamic of zooplankton was realized in 9 ponds (5.7 x 5.7 x 1 m) at a flow rate of 0.05 l/s. It was carried out from May to November 2016 at the Farm of Application and Research of the University of Dschang, Western region - Cameroon. At each of the randomly selected ponds, one of the doses of 0; 800 and 1000 kg/ha was administered weekly. Different water quality characteristic and zooplancton were measured at 15 days interval. At the end of the study, the results showed that, nitrites (5.64 ± 0.19 mg/l), nitrates (6.23 ± 0.13 mg/l), phosphates (3.34 ± 0.07 mg/l), as well as the density (51858 individuals/liter) and biomass (49.3 mg PS) of zooplankton were significantly higher (p
<0.05) in the treatment 1000 kg/ha. The biomasses of 32.3; 13.9 and 3.2 mg/l dry weight respectively of copepods, cladocerans and rotifers were obtained in the treatment 1000 kg/ha. In practice the treatment 1000 kg/ha could be used for a better weekly fertilization.Pages: 123-127 | 680 Views 24 DownloadsDownload Full Article:
