Pig slurry was used, coming from the zootechnical center of Campus II/UNOESTE, for the composition of the treatments, which are: T1 = Control sample--50% pig slurry and 50% water; T2 = 50% pig slurry and 50% water +Eichhornia crassipes (Mart.) Solms (Figure 1); T3 = 50% pig slurry and 50% water + Pistia stratiotes
is also known as Pistia stratiotes
, a scientific name that does little to describe what it looks like, hence we have other names: water cabbage, Nile cabbage and water lettuce.
Also, in the list are Hygrophila auriculata (Indian paintbrush); Mangifera indica (Mango); Pistia stratiotes
(Water lettuce); Hyphaene thebaica (Gingerbread tree); Boscia senegalensis (Senegal boscia); Ipomea asarifolia (Ginger-leaf morning glory); Cucurbita pepo (Pumpkin); African locust bean tree; Bombax costatum (Silk cotton tree) and Musa acuminate (banana).
"Other than the overhead cover, it's the root system of water lettuce that attracts fish." Indeed, Pistia stratiotes
sprouts long, feathery root systems that appeal to a variety of invertebrates such as crayfish, which feast on the sweet plant flesh.

Aquatic plants like Eichhornia crassipes, Azolla filiculoides, Pistia stratiotes
, Hydrilla verticillata, Typha domingensis, Salvinia Cucullata, Azolla caroliniana, Azolla pinnata, Lemna minor, Lemna aequinoctialis, Lemna gibba, and Spirodela polyrhiza are suitable aquatic plants for the removal of heavy metals as reported by several researchers [21-27].

Aquatic macrophytes were placed, water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes
) in a proportion of 1: 1 in the tanks covering half of the surface, using wires fixed to the edges to delimit this space.

for treatment of urban sewage in Israel.
All the aquariums contained 8 L of previously declorinated tap water, 1 cm base layer of soil and sand, five small stones (150 g approximately) and four macrophytes (Pistia stratiotes
), so as to simulate some natural conditions for these species.
