Energy facilities and water are inextricably linked. Accordingly, the issue of water quality, its transformation as a result of industrial use of energy facilities and the assessment of further use for aquaculture purposes is an urgent task of our time, especially in relation to weather and climate risks for industries. The article provides a classification of water according to the water supply technology of energy facilities by temperature factor and the possibility of using it for aquaculture tasks. In total, three classes of water are distinguished according to the temperature factor: waters with natural physical and chemical characteristics, where the temperature regime of reservoirs corresponds to the geographical zone in which the reservoir is located (cultivation of fish associated with fish-breeding zone in which the reservoir is located); water of bassin-coolers of energy facilities, characterized by the presence of a zone of increased temperatures as a result of the discharge of heated water (organization of flood-proof farms with polycyclic production); water of cooling ponds (cultivating fish capable to the fight against eutrophication).

Physical and chemical characteristics of honey may vary due to the diversity of flora and soil characteristics, or seasonal factors. This study was carried out in two counties, Nova Aurora and Ubiratã, located in the West and Center-West regions of the State of Paraná. The objective of the study was to verify if the physical and chemical parameters of Apis mellifera (L.) honey are in accordance with the national standard, as well as to verify how the 21 samples collected in the two localities are grouped, based on the physical, chemical and pollen characteristics. Honey was analyzed for sugar, ash, protein, moisture, color, electrical conductivity, formaldehyde index, diastase and viscosity. Samples of honey containing the dominant pollen types Glycine max (L.) Merr. and Eucalyptus sp. formed groupings similar to those based on physical and chemical characteristics, however, the multivariate classification of honey samples in groups based on pollen types was not an efficient method to group samples of polyfloral honey.

The objective of this present study was to investigate the effect of feeding fermented mixture of papaya leaf and seed meal (FERM) on the physical and chemical characteristics of meats of the Indonesian indigenous crossbred chicken (IICC). The study was carried out with 300 day-old IICC. The chicks were randomly distributed to five treatment groups, i.e., CONT (control diet based on corn-soybean- diet), FERMA (diet containing 1% FERM), FERMB (2.5% FERM), FERMC (5% FERM) and FERMD (7.5% FERM). Each treatment group consisted of 6 replicates with 10 IICC in each. At week 8, one chick from each replicate was randomly taken and slaughtered. After being de-feathered and eviscerated, samples from breast and thigh meats were obtained. Results showed that the increased levels of FERM was followed by the increased (P<0.05) pH values, moisture and crude protein content of breast meats of the IICC. Dietary incorporation of FERM especially at the level of 2.5% increased (P<0.05) the content of fat in the breast meat of IICC, while further increased levels of FERM did not alter (P>0.05) the fat content of the IICC breast meat. Dietary treatment did not have any effect (P>0.05) on the lightness (L*) values of breast meat of the IICC. The redness (a*) values were higher (P<0.05) in FERMD breast meat than other. FERM diet resulted in lower (P<0.05) yellowness (b*) values in the IICC breast meat. The pH values and moisture content of thigh meat increased (P<0.05) with the increased level of FERM. The WHC decreased (P<0.05) with the elevated levels of FERM in the diets. There was an increase (P<0.05) in crude protein concentration in FERMA as compared to the other meats. Crude fat and ash concentrations in thigh meat were affected (P<0.05) by the treatments. Dietary treatments had no impact (P>0.05) on L* values of thigh meats. Feeding FERM at 7.5% from diets increased (P<0.05) and decreased (P<0.05) the redness and yellowness of meats. In conclusion, dietary inclusion of FERM especially at the level of 7.5% from diets improved the physical and chemical characteristics of the IICC meats.
