“…This could be accomplished by integrating aquaculture production with the on-site transformation of fish pond sediments through different biological processes. Kouba et al (2018) suggested the application of on-site vermicomposting as it is considered to be a clean and sustainable method for converting fish pond sediment into vermicompost of high value for agricultural use. In addition, fish pond sediment with suitable amendments can be used as a growing media for earthworm biomass.…”

The recent increase in fish production has resulted in the accumulation of fish pond sediment. This sediment accumulates over time and can lead to a reduction in the depth of ponds and in the living space available for fish, it may also lead to a depletion in dissolved oxygen. Therefore, the removal of sediment from fresh water ponds is crucial for pond maintenance, and thus economical fish production. Fish pond sediment is rich in nutrients and organic matter, and therefore it may have potential as a fertilizer in crop production, nursery pot culture, etc. However, it contains compounds that undergo rapid degradation producing unpleasant odours and posing a threat to the environment, therefore it needs to be managed and handled efficiently in an environmentally sound and sustainable manner. The overall goal of this study was to analyse the current state and management practices of fish pond sediment generated in the existing aquaculture systems, with special reference to organic aquaculture, and the potential for the recovery of nutrients through bioconversion processes to organic fertilizers.

Increased fish pond production is associated with the generation of various waste including fish pond sediments. Fish pond sediments could be a valuable source of nutrients for growing plants, however they require further processing in order to be applied to soil. Composting is considered one of the methods for processing fish pond sediments. The aim of this work was to investigate the potential of organic fish pond sediments to be managed through laboratory composting with selected waste materials and evaluate the fertilizing potential of the obtained compost. The scope included: (1) analysis of organic fish pond sediments, (2) laboratory composting of organic fish pond sediments with wheat straw and green grass, (3) analysis of the obtained composts, (4) preparation of growing media with selected additives, (5) analysis of the properties of the prepared growing media and (6) analysis of the effect of the investigated growing media on the growth of Phaseolus vulgaris L. in pot experiments. The addition of cardboard waste and woodchips derived biochar to the obtained compost improved significantly the growth of the roots of Cardamine L. Also, the content of carbon and nitrogen in the compost mixtures increased. The addition of M1 (compost from organic fish pond sediments and 1% of biochar) to the soil had a significant impact on the growth of white beans.

“…This creates new prospects for sustainable development of the rural economy through formation of production chains of poultry, cattle and aquaculture. With regard to the latter, we should note the special importance of its combination with vermicomposting, since worms are a valuable protein feed for hydrobionts, and silt formed in aquaculture reservoirs is as much valuable substrate base for vermiculture as cow manure [14].…”

The article deals with the theoretical aspects of inclusive green economy and practical prospects for its elements' introduction in rural areas of Russia. Discursive variety of interpretations of the green economy allowed identifying the green economy of rural areas with decoupling effect as elimination of direct correlation between the growth of agricultural production and anthropogenic load on agrobiocenoses. Practical implementation of the green economy's inclusive component consists in creation of new production chains in rural settlements and small towns with similar socioeconomic conditions. These chains should be affordable for small enterprises and profitable enough for the formation of financial flows that would ensure socioeconomic development of rural areas of Russia and prevent their decay and depopulation. Scientific and industrial cooperation in the field of biotechnology can solve this problem in combination with ensuring environmentally sustainable development. The production of vermicompost as an effective organic fertilizer that provides enhanced reproduction of soil fertility is the most affordable and cost-effective means of rural areas' development. The article analyzes the influence of vermicompost on agrobiocenoses, the prospects of its sale, the raw materials used for its production, as well as replicability and scalability of these technologies. This provides for a socioeconomic basis of expanded reproduction of soil fertility and improving living standards of the rural population.
