This paper is a review of literature of water hyacinth (Eichhornia crassipes); what it is, why it is of scientific importance, problems it causes, how it can be controlled, and how it can be a source of livelihoods. The review has shown that water hyacinth is native to the Amazon Basin and one of the world's most noxious aquatic weed. Lack of natural enemies together with nutrient enriched water bodies facilitate the spread of water hyacinth in temperate, tropical and sub-tropical waters. The weed causes a variety of socio-economic and environmental problems when its rapid mat-like proliferation covers areas of fresh water. With regards to its control, the mechanical method is the most cost-effective, followed by the biological, manual and chemical methods. Regardless of its problems, water hyacinth has been found to be useful for industrial, agricultural, household and environmental purposes.

The study of suitability for the use in agriculture of sludge deposits and hydrochemical indices of water bodies of fish-growing enterprise of LLC “Albashi” were carried out. It is an enterprise engaged in breeding and growing pond fish and sturgeon in pools and gardens, crayfish, growing aquapon greens. Fresh water bodies of reservoir type LLC “Albashi” contain a large number of bottom deposits. The layer of sludge deposits on the bottom in places reaches the power of 2-5 meters, and the underground power is difficult. Bottom sediments were taken from a depth of 1.0-1.2 m from the surface. The hydrochemical regime of the studied water bodies fully corresponds to the cultivation of aquaculture objects and hydroponic plants. Sufficient suspended matter in water (8.2 mg/dm3). The complete absence of dichlorodiphenyl trichloroethane, its metabolites and pesticides characterizes the products produced as environmentally safe. Consequently, bottom sediment site under study can be considered suitable for agricultural production.

AbstractIn this work, the authors examined the presence of cyanobacteria and cyanotoxins in 21 samples collected from fresh water bodies located in 5 provinces in Poland: Lublin (2), Podlasie (1), Pomerania (6), Warmia-Masuria (1) and Wielkopolska (11). In addition, to determine the general pattern of geographical distribution, frequency of cyanobacteria occurrence, and cyanotoxins production, the published data from 238 fresh water bodies in Poland were reviewed. On the basis of these collected results, we concluded that Planktothrix, Aphanizomenon, Microcystis and Dolichospermum were dominant. The general pattern in geographical distribution of the identified cyanobacterial genera was typical of other eutrophic waters in Europe. The production of cyanotoxins was revealed in 18 (86%) of the 21 samples analyzed in the present work and in 74 (75%) of the 98 total water bodies for which the presence of toxins had been examined. Among the 24 detected microcystin variants, [Asp3]MC-RR was most common. These results can be verified when more data from the less explored water bodies in the southern and eastern parts of Poland are available.
