“…Gambar 1. Granuloma atau iniltrasi sel mononuklear lamela primer serta fusi dan edema lamela sekunder ikan akibat akumulasi merkuri (Hg) (Adams dan Sonne, 2013) Hati sangat rentan terhadap pengaruh zat kimia dan menjadi organ sasaran utama dari zat beracun (Bakos et al, 2019;Prysiazhniuk et al, 2019;Sayed et al, 2019;Mahmoud et al, 2020). Hal ini terjadi karena sebagian besar racun atau zat toksik yang masuk ke dalam tubuh dan diserap oleh sel selanjutnya akan dibawa ke hati oleh vena porta hati, sehingga hati berpotensi mengalami kerusakan (Abdel-Warith et al, 2011;Hegazi et al, 2015).…”

The problem of pollution that occurs in the aquatic environment is getting out of control and causes the degradation of fishery resources which are important for humans. One of the pollutants from industrial activities is heavy metal. There are various kinds of heavy metals, mercury (Hg) is the most dangerous heavy metal. Mercury (Hg) enters directly into the waters through rainwater and leaching the soil and river flows which are then absorbed and metabolized by microorganisms. Mercury (Hg) is difficult to degrade from the body, because mercury (Hg) is actively involved in the food chain. Microorganisms feed molluscs, crustaceans and fish which are a source of protein for humans. Mercury (Hg) toxicity in fish can result in a stress response in fish which results in impaired growth, immune system, and changes in tissue structure. This brief review aimed to enrich the scientific repertoire of the toxicity of mercury (Hg) in fish and its effects on humans. This review was a non-experimental research by conducting research around the literature

This scientific article describes the technology and stages of designing a fishery for growing silver carp in polyculture with carp in conditions of the LLC “Kovcheg” of the Kyiv. In the conditions of this economy the project of cultivation of fish in polyculture was developed, where calculations of average monthly temperature of ponds, content of dissolved oxygen in water were carried out, indicators of a source of water supply of ponds were analyzed, economic efficiency of cultivation of silver carp in polyculture with carp was carried out. Fish farms have a number of significant problems today, that prevent full and easy development – these are financial difficulties in the state, namely: disruption of economic ties, deterioration of the ecological condition of inland waters, insufficient work on the reproduction of fish stocks. In order to get fish farming out of the crisis, ensure sustainable development of the industry, strengthen the country's food independence, it is necessary first of all to solve issues related to environmental and economic problems of fisheries development, improving the economic mechanism of fisheries management, intensification of investment processes and innovations aquatic living resources. The fisheries sector includes the extraction, processing, reproduction and increase of stocks of fish and other aquatic organisms in natural and artificial reservoirs. It provides valuable food, feed, medicine and technical products. Fisheries are aimed at preserving and improving fish stocks in natural reservoirs and breeding fish in artificial reservoirs. In order to ensure food security of Ukraine, it is necessary to work on the following areas: scientific substantiation of the raw material base and rational fishing, protection of aquatic ecosystems, technology of processing of aquatic fish resources.

“…In addition to exogenous intake, there is endogenous contamination with nitrogen and phosphorus substances from the remains of dead organisms. Inorganic nitrogen and phosphate ion are the final products of decomposition and mineralization of organic matter (Randall & Tsui, 2002;Prysiazhniuk et al, 2019). In excess, these ions can significantly affect the pH value of water, and some nitrogen substances adversely affect the viability of aquatic organisms (Wurtsbaugh et al, 2019).…”

Biogen elements that enter the water in large quantities are one of the main pollutants in the aquatic environment. They lead both to eutrophication of the reservoir and a decrease in the viability of young fish, acting as toxin. The energy enzyme activity (lactate dehydrogenase and succinate dehydrogenase), nitrogen (glutamate dehydrogenase) metabolism, dephosphorylation processes, and immune protection (by alkaline phosphatase activity) under the long-term action of ammonium nitrogen and phosphorus phosphates was studied. The biological object of research were 30–45 day common carp juveniles (Cyprinus carpio L.). According to our results, the peculiarities of the adaptive reactions of young carp to the action of these compounds have been established. We revealed, that under the loading of ammonium nitrogen, the activity of the processes of anaerobic digestion of energy-intensive complex increases directly in the organs of neutralization and excretion of nitrogenous compounds, namely in the gills. In general, the body of the carp due to these actions reduces the total energy consumption for maximum survival in these environmental conditions. We registered, that under the influence of elevated concentrations of phosphorus phosphates, oxidation of biogen elements to the body's energy needs in the presence of oxygen was observed. The processes of immune defense and dephosphorylation, for which LPh is responsible, also the detoxification, the excretion of nitrogenous substances from the body of carp (GDG) occurred differently depending on the chemical nature of the toxin. Thus, under the influence of ammonium nitrogen there was an increase in the activity of LPh in the highest concentrations of the toxin, and the activity of GDG decreased to reduce the production of ammonia, to avoid endogenous intoxication. Through these load of potassium monophosphate, the rise in the activity of immune defense processes and the involvement of ammonia in the cycle of tricarboxylic acids due to reamination to the energy supply of the processes of counteracting the weak but chronic toxic effects of orthophosphate ion. Under the load of ammonium chloride was observed not only the use of “traditional” energy substrates - glycogen and lipids, as well as proteins, which indicates the high toxicity of this compound for the body of young carp. Through the action of orthophosphate ion, the active use of lipids and even the activation of gluconeogenesis at maximum concentrations, as a reaction to weak long-term chemical stress.
