Effects of doses of chicken manure on the biodiversity of zooplankton populations in ponds

Abstract

In order to evaluate zooplankton biodiversity for the purpose of optimizing fish production in pond, the effect of doses of chicken manure was assessed from May to November 2016 in 9 ponds (5.7 x 5.7x 1 m) with a residual flow rate of 0.05 l/s. At each of the randomly selected ponds, one of the doses 0; 800 and 1000 kg / ha was administered weekly. The results showed that, nitrites (5.64 ± 0.19 mg/l), nitrates (6.23 ± 0.13 mg/l) were significantly (p
