AbstractTreatment of a pond with a 0.5% sand granule formulation of SIR-8514 yielded a maximum, concentration (4.6 ppb) by 1 day following the application. No residues were detected in the pond sediment and by 28 days posttreatment residues were not found at any depth of the water column. Emergence of pestiferous dipterans was reduced by >99%, and planktonic arthropod populations decreased by >90% following the treatment. Planktonic rotifers and dinoflagellates, and benthic organisms were less severely affected.Bluegill sunfish (Lepomis macrochirus Rafinesque) and mosquitofish (Gambusia affinis Baird and Girard) accumulated maximum concentrations (ca. 400 ppb) of SIR-8514 by 2 days posttreatment. No residues in fish were detected by 28 days posttreatment, and no fish mortality was observed.

Phenol and Phenolic compounds has several sources including industrial wastes, coal , wood distillation, road tars, petroleum refining, chemical and plastics manufacture, domestic sewage discharges, natural sources such as plant material decay and leaching from coal and oil deposits enter natural water system and affect the fish and other aquatic organisms , So the static renewal bioassays were done to study the influence of pH on the lethal toxicity of phenol, para chlorophenol and pentachlorophenol to the freshwater fish Gambusia affinis. The studies shows that phenol, para chlorophenol and pentachlorophenol decreased their toxicity as the pH increased to the said fish .The24,48,72 and 96 hours LC50 values were found to be 48.0,45.0, 43.0 and 41.0 mg/l at pH 6.0 and at pH 7.5 the 24,48,72 and 96 hours LC50 values were 50.0, 48.0, 46.0 and 44.0 mg/l respectively for the fish exposed to phenol, And at pH 6.0 the 24,48,72 and 96 hours LC 50 values were 24.0, 21.0, 19.0, 17.0 mg/l and at pH 7.5 the 24, 48, 72 and 96 hours were 30.0, 28.0, 25.0 and 22.0 mg/l respectively for the fish exposed to para chlorophenol .The LC50 values at 24,48,72 and 96 hours at pH 6.0 were 0.12, 0.10, 0.09 and 0.07 mg/l respectively and at pH 7.5 The LC50 values were 1.23, 1.19, 1.15 and 1.11 mg/l respectively for the fish Gambusia affinis.

Aquaculture Production

Aquaculture production is a promising direction for the development of food production. Like traditional types of animal husbandry, it needs effective medicines for veterinary use, which would ensure not only the well-being of farmed aquatic organisms, but also increase the safety of the fish products and non-fish objects of fishing. The development of measures to control epizootic processes in aquatic organisms is impossible without the creation of new immunological preparations. The development and use of immunobiological drugs will reduce the use of antimicrobial agents. The corresponding set of pharmaceutical drugs was transferred from the traditional veterinary medicine, but due to the peculiarities of the biology of aquatic animals, their immunity and the characteristics of specific pathogens, this could not be done with biological products. The short development time in the aquaculture industry poses current challenges in the form of a lack of basic and applied research for relatively poorly understood groups of new pathogens. The immunological processes associated with the development and intensity of the immune response in aquatic organisms require a detailed study. For domestic aquaculture producers, the analysis and dissemination of the experience accumulated by mankind and the application of advanced developments in this area are even more relevant, since Russia is just beginning its path of intensifying aquaculture production. At the same time, it is clear that the prohibition of the use and monitoring of antimicrobial agents in food products and feed requires a change in the approach to the problem and will lead to the creation of new immunobiological drugs. The market for immunobiological preparations for aquaculture is the most promising for development. In the article, the authors provide data on the development and registration of vaccines for aquaculture in Europe, North and South America.

Cyanide (CN) through leaching process in the gold processing could produce tailings that have negative impacts on the aquatic environment. To determine the acute and chronic effects of cyanide on aquatic organisms, toxicity tests have been conducted in the laboratory using Daphnia sp.This zooplankton organism is recommended by APHA as standard test animals. In this study the test concentrations refer to the Ministerial Decree No. 202 of 2004 and Government Regulation No. 82 of 2001. Cyanide was analyzed as free CN and WADS CN. The result of acute toxicity test using cyanide solution showed that Daphnia could survive a maximum concentration of 0.2 ppm. LC50 values for 24 and 72 hours were 0,59 mg/L and 0,10 mg/l, respectively. The LT50 was found at 42 hours. Daphnia sp. produced different numbers of offspring at different CN concentrations, and changed their reproduction pattern from parthenogenesis to sexual reproduction after exposure to a cyanide concentration of 0.1 ppm for 24 hours©  Sianida (CN) melalui proses leaching dalam proses pengolahan emas menghasilkan limbah yang dapat memberi dampak negatif bagi lingkungan perairan. Untuk mengetahui sampai seberapa jauh CN dapat memberi efek akut dan kronis terhadap biota air, telah dilakukan uji toksisitas di laboratorium dengan menggunakan Daphnia sp. Zooplankton ini direkomendasikan oleh APHA sebagai salah satu hewan uji standar. Dalam penelitian ini konsentrasi uji yang dipakai mengacu pada peraturan yang berlaku, yaitu Keputusan Menteri No. 202, Tahun 2004, dan Peraturan Pemerintah No. 82, Tahun 2001. Analisis sianida yang dihitung adalah nilai free CN dan WADS CN. Hasil penelitian uji toksisitas akut dengan menggunakan larutan sianida didapati Daphnia mampu bertahan hidup sampai pada konsentrasi 0,2 ppm dan nilai LC50 berada pada konsentarsi 0,1 ppm serta LT50 pada jam ke 42. Hasil uji efek kronis, Daphnia sp. menghasilkan jumlah anakan yang berbeda pada konsentrasi CN yang berlainan, dan mengalami perubahan pola reproduksi dari partenogenesis menjadi seksual setelah dipaparkan pada kosentrasi sianida 0,1 ppm selama 24 jam©

Wastewater samples were collected from an oil industry at the point of discharge for a period of two years, from January 2018 – December 2019. The wastewater samples were analyzed for different physicochemical parameters such as temperature, turbidity, total dissolved solids (TDS), total suspended solids (TSS), conductivity, pH, alkalinity, salinity, total hydrocarbon content (THC), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to examine their conformity to fulfill requirements as recommended by World Health Organization (WHO), Federal Ministry of Environment (FME) and Drinking Water Association (DWA). The results indicated that all the parameters in the discharged wastewater were within acceptable limits of the regulatory bodies. The field data showed that the investigated firm conformed to the law by carrying out proper procedures before discharging the effluents into the public drain and river. Therefore, the release of wastewater from the industry doesn't constitute a danger to the environment as well as aquatic organisms.
