This paper is a further analysis of data from two experiments carried out in that framework, to explore periphyton–environment relationships in the absence of fish grazing pressure. Factor analysis and ANOVA models applied to data matrices of water quality, plankton and periphyton parameters allowed

The absence and presence (0 and 0.5 individual m−2) of tilapia were investigated in 40 m2 ponds stocked with 3 prawn juveniles (individual weight 5 g) m−2 with or without added substrates for

Sedimentation was measured by placing sediment traps in the pond bottom. Starting on days 7 and 9, two sediment traps were placed 20 m apart at the pond bottom. The sediment traps were made from PVC pipe with a diameter of 7 cm. ...
