The reuse of fish-farming effluents represents a sustainable alternative for agriculture, as it combines the supply of water and nutrients in a single input, reducing the dependence on mineral fertilizers and optimizing water use. This dissertation evaluated the agronomic potential of fish-farming effluent in the production of cherry tomato (Solanum lycopersicum var. cerasiforme), integrating (i) a systematic literature review with bibliometric analysis and (ii) seedling production experiments conducted in the municipality of Tangará da Serra, Mato Grosso, Brazil.The systematic review (2005–2023) was carried out in the Web of Science, Scopus, and Google Scholar databases, using descriptors in Portuguese and English. After applying inclusion and exclusion criteria, eight studies were considered relevant. A recent increase in publications was observed, with 2023 standing out, and a predominance of studies conducted in Brazil. The bibliometric analysis revealed editorial dispersion among multidisciplinary journals and a predominance of keywords related to water reuse, irrigation management, salinity, and plant physiological responses, confirming that this is a consolidating research field in need of methodological standardization.The seedling production experiment was conducted at the State University of Mato Grosso (UNEMAT), in Tangará da Serra – MT, Brazil. Different substrates (commercial, washed sand, fish-farming sludge, and combinations) were evaluated under distinct irrigation strategies, including the application of fish-farming effluent. The experimental design was completely randomized, in a 4×4 factorial arrangement, with three replications of 10 subsamples. Morphological variables of the seedlings were monitored, including height, stem diameter, number of leaves, and fresh and dry mass of both shoot and root systems.
