Solms-Laubach ABSTRACT Objective: To preserve and enhance the aquatic ecosystems of the Region of Littoral (Cameroon) threatened by invasive macrophytes, an ecological study highlighting the distribution of water hyacinth (Eichhornia crassipes) in aquatic ecosystems was conducted. Methodology and results: During this study,

The floristic inventory showed that 2 species (Eichhornia crassipes and Panicum maximum) were the most represented. Sorensen indexes were near 0 reflecting a low level of similarity between the communities. Thus, E. crassipes was rich in water (about 90%) and shows an average energy value of 300kcal / 100g of dry matter. The carbohydrate content varied from 28 to 72g / 100g, protein <20% lipids and there are traces. There was a high ash content.

Solms-Laubach 9523 Conclusion and application: E. crassipes was widely distributed in different sites and showed high values of carbohydrates. These values suggested that this plant can be used in breeding purposes. This plant can thus be used for biogas or compost production
