With the disorderly increase in global environmental problems, the cultivation of aquatic organisms is a promising path for sustainable food production. The quality of water, both at the entrance and exit of the production of aquatic animals, needs to be maintained following the parameters specified by local legislation. This study aimed to investigate the removal of contaminants from fish farming wastewater associated with the production of freshwater microalgae biomass. Six completely randomized treatments were used in triplicate: with the addition of microalgae C. sorokiniana in fish farm wastewater (W+Cs), the addition of C. sorokiniana in wastewater enriched with NPK fertilizing (W+F+Cs) or sugarcane vinasse (W+V+Cs), only wastewater (W), wastewater supplemented with fertilizer (W+F) or vinasse (W+V). The wastewater was used in natura to allow the development of autochthonous microalgae. The microalgae C. sorokiniana grew rapidly in effluents enriched with NPK and vinasse. After 28 days of bioassay, the concentrations of several contaminants in the water were reduced: zinc (20 to 88%), lead (5 to 83%), aluminum (56 to 75%), manganese (56 to 72%), cadmium (9 to 52%), calcium (16 to 24%) and magnesium (12 to 33%). Our results indicated that the production of microalgae biomass can be integrated with the treatment of fish farming effluents to reduce the environmental burden and increase the economic bonus for adopting a sustainable production method. However, our results also indicated the importance of introducing a microalgae strain with high productive performance and supplementing the wastewater to obtain rapid biomass.

Algae are aquatic organisms that can be found in a wide range of water bodies. Algae, a form of aquatic organism, is found in many different water types. Besides being relatively easy to maintain, algae are also numerous, making them a good choice for biomass production. The filamentous Spirogyra sp., a common green alga, tends to grow in freshwater. It is said that this macroalga has a wide variety of biotechnological applications. Research in this area highlights biomass's creation and builds on our understanding of the composition of macroalgae generated in fish farm wastewater. A study of Spirogyra in undisturbed fish farm wastewater was conducted in this study. Various algal species were evaluated for their qualities, including biomass yields and productivity, protein, fat, and carbohydrates. This investigation has confirmed that the nutrients in fish farm effluent are suitable for cultivating algal biomass. Protein, lipid, and carbohydrate levels in unaltered fish farm effluent were the highest for Spirogyra, with percentages of 19.03, 8.38, and 45.71%, respectively. Thus, it was the most suitable organism for various biomass-based applications and nutrient removal.

Objective of research: to perform the parasitological monitoring we have to study the parasite fauna in fishes from different fish farm factories, calculate the index of similarity, estimate the influence of abiotic and biotic factors on the ecosystem of fish-breeding reservoirs. Materials and methods: parasitological monitoring of factory fish farms was conducted by the method of complete and incomplete parasitological examination taking into account the data obtained from various fish-breeding reservoirs. Results and discussion: the parasite fauna of cyprinid fishes is represented by 56 species, carriage of causative agents of parasitic diseases in fishes is detected. Index of similarity of parasite fauna in carps has been studied and typification of agricultural reservoirs carried out. Index of similarity between the parasite fauna in carp and herbivorous fish was 22–33 %, carp and rough fish - 18–30,7 %. Influence of abiotic (oxidability, reduction of oxygen and nitrogen ammonia concentration, mineralization) and biotic – anthropogenic factors (violation of processing technologies, veterinary and sanitary rules of fish transport and fish farming operations) on fish infestation with parasites was studied. The role of parasitological monitoring in prevention and elimination of fish diseases was shown.

Recirculation System

Aquaculture represents the fastest growing animal husbandry in many countries. However, higher intensity of fish farming can pose higher health hazards, too. We monitored the health status of fish from one fish farm in South Bohemia and discovered the main health problems in the breeding. For two years we examined a total of 224 specimens of brook trout (Salvelinus fontinalis), 126 specimens of hybrids (S. fontinalis×S. alpinus), 49 specimens of rainbow trout (Oncorhynchus mykiss) – all clinically healthy, and 100 clinically diseased or freshly dead fish. We registered skin erosions mainly in the caudal peduncle and tail fin. Two parasite species were identified (one protistIchthyophthirius multifiliisand one nematodeRaphidascaris acus) by parasitological examination. The epidemiological indicators ofI. multifiliiswere low. The prevalence of adultR. acuswas 0–86% with a maximum in June. From November, capsules with larval stages ofR. acusappeared in internal organs. Their highest intensity (200 pieces) and prevalence (100%) were detected in October. By microbiological examination of skin and gills, we identified changes in the density of bacterial population and its species composition dependent on water temperature and fish density. The most important problem on the monitored fish farm seems to be furunculosis of salmonid fish in all clinical forms, and the high intensity of larval stages ofR. acus. The originality of this study is based on the fact that the observed breeding employs the first Danish recirculation system in the Czech Republic and no recent information about health problems has been available.

Species diversity, dominance and abundance of the phytoplankton community of the Ranjit Sager Wetland were studied during June, 2012 to May, 2014 on monthly basis. The main aim was to provide information about overall phytoplankton diversity of this wetland. Phytoplankton samples were collected using phytoplankton net and preserved in 5% formaldehyde solution on the spot, then brought to the laboratory for further analysis. Algae belonging to Cyanophyceae, Chlorophyceae and Bacillariophyceae were recorded. The Bacillariophyceae was the most dominant group followed by the Chlorophyceae and Cyanophyceae. A total of 26 genera were recorded, 12 were belonged to Bacillariophyceae, 11 to Chlorophyceae and 3 to Cyanophyceae. The different types of indices such as Margalef’s index, Simpson index, Shannon-Weaver index and species evenness index were employed to analysis the data. Phytoplankton converts light energy to chemical energy by the process of photosynthesis so they act as primary producers and food for variety of aquatic organisms. Phytoplankton are also act as efficient bio-indicators to measure quality of water.

Water plays a key role in the survival, growth and reproduction of aquatic organisms. Therefore maintaining good quality of water physico-chemical parameters would ensure optimum productivity of aquatic fauna. The study evaluated water physical and chemical parameters (temperature, hydrogen ion concentration (pH), conductivity, dissolved oxygen (DO) and biochemical oxygen demand (BOD) of Bodo Creek. Sample was collected for 5 months (July 2020 – November 2020) at locations previously studied (before-spill baseline studies, 3 years, 5 years, and 7 years after-spill); by using the sampling methods used in previous studies. Spatially, there was no statistically significant difference in temperature (p > 0.05 = 0.997), pH (p > 0.05 = 0.496), DO (p > 0.05= 0.34) and BOD (p > 0.05 = 0.644). However, the difference in conductivity between the stations was statistically significant (p < 0.05 = 0.006). On monthly basis, there was a significant difference in temperature (p < 0.05 = 0.000) and pH (p < 0.05 = 0.005). In contrast, there was no statistically significant difference in conductivity (p > 0.05 = 0.633), DO (p > 0.05 = 0.559) and BOD (p > 0.05 = 0.75). Most of the physico-chemical parameters were not within the WHO recommended levels for the survival of aquatic lives, indicating a high level of environmental pollution in Bodo Creek. This study provides dataset for future evaluation of the water physico-chemistry of Bodo Creek.

Aquaponics is an innovative food production method that combines the production of aquatic organisms with plant production. This can have environmental advantages such as reducing land conversion and resource input and waste output through nutrient cycling. To support the dissemination of aquaponics, key stakeholders need to be appropriately informed about this production method, an aspect that has received little attention so far. In this pilot study, visual perception of information about aquaponics was explored using eye tracking combined with a questionnaire. The results show that people distinguish between aquaponics variants when evaluating aquaponics. A production system with a more natural appearance is preferred. Allocation of visual attention is linked to the specific information content and to the assessment of the naturalness of aquaponics production. The results of the present study could form a basis for further research, not only to make information about food production systems more appropriate but also to develop food production systems in a way that people become more aware of the sustainability aspects of production methods and its products.
