| The influence of different types of organic manure in the phytoplankton community is provided. Experiment was undertaken during 40 days in 1000L asbestos tanks. Tanks were fertilized with poultry (PO), pig (PI), cattle (CA) and rabbit (RA) manure, in a randomized design, with four treatments and five replications. First fertilization consisted of 50 g of manure, with 25 g fertilizations at seven-day intervals. Plankton was collected every three days by filtering 250 mL of water in a 20 µm net and fixed in 10 mL formaldehyde 2%. Qualitative and quantitative analysis was undertaken by optic microscope. At the same time, physical and chemical variables were monitored. Highest mean density of phytoplankton was detected with PO on the 40th day (26,842... |

| Aiming to determine the influence of organic fertilizer on zooplankton organism community twenty 1,000 liter ponds were used distributed in four treatments with poultry, cattle, rabbit or pig manure with five replicates in a complete randomized design. Planktons were collected every three days whose physical and chemical parameters were monitored and qualitatively and quantitatively analyzed. Poultry manure showed to be the best fertilizer followed by pig, cattle, and rabbit fertilizer respectively for plankton density in which Brachionus sp, Keratella sp, Vorticella sp and Copepoda's nauplius predominated. Therefore cattle and rabbit manure led to lower species diversity. The results led to the conclusion that the manure used exerted a greater influence... |
