Abstract: It is widely accepted that fish farms (FF) have important contribution to input of nutrients into water, however fundamental knowledge regarding the influence of land use and land cover (LULC) on the water quality of fish farms is still lacking. The aim of this study was to assess the linkages between the LULC types and the water quality parameters in FFs. Three specific objectives were set: (1) to characterize the current water quality standards in four FFs (FF1, FF2, FF3, FF4) installed in the Ilha Solteira reservoir; (2) to delineate and analyze the LULC changes in sub-basins of tributaries where FFs are installed; (3) to elucidate the interactions between LULC and water quality in FFs. Results indicated signs of eutrophication in FF2 in both the dry and wet seasons. The mainly LULC was decrease of pasture and increase of sugarcane crops were observed in the four FFs' sub-basins between 2005 and 2018. Sugarcane land uses showed a significant positive correlation with SO4, Mg and K (r > 0.95, p < 0.005). The most likely source of these highlighted parameters may come from mineral fertilization, decomposition of the plinth in sugarcane and the application of vinasse to irrigate and fertilize crops. Concentrations of SO4, Mg and K observed in this present study do not cause direct toxic effects to Nile tilapia in fish farms. However, indirect impacts to water quality should be expected due to enhance primary production and promotes water eutrophication, as observed in FF2. Based on our results, we suggest that the criteria "basin characteristics", including future sugarcane expansions, should be adopted to gather information in identifying areas more suitable for aquaculture parks that the Brazilian government intends to install in the large reservoirs.

Durante 13 meses foram acompanhadas as mudancas sazonais dos eletrolitos calcio (Ca), fosfatos (PO4), potassio (K), cloretos (CI), cobre (Cu) e zinco (Zn) no sangue de 20 de vacas "aneloradas" mantidas sob pastejo continuo de Brachiaria decumbens com alta taxa de lotacao. As vacas apresentaram-se hipocalcemicas e hipofosfatemicas durante praticamente todo o ano. Na primavera, com a brotacao dos pastos (novembro e dezembro), vacas mantidas em pastos de solo argiloso foram mais propensas a alcalose metabolica, caracterizada por hipocalemia e hipocloremia, do que vacas mantidas em pastos de solo arenoso. Os animais apresentaram-se com niveis sericos normais de Cu, 0,79 e 0,81ug/ml e Zn, 1,43 e 1,33ug/ml, quando mantidas em solos arenoso e argiloso, respectivamente, apesar de os pastos estarem deficientes nesses minerais. O tipo de solo alterou a composicao de minerais na braquiaria e influiu significativamente nos niveis sericos de P, Mg, K, CI e Zn. Solos arenosos mostraram teores sericos significativamente mais elevados de P, Mg, K e CI do que os solos argilosos. |
