“…The capture and transportation of freshwater fi sh causes stress, which is accompanied by severe hyponatremia (35)(36)(37). It is possible to catch simultaneously a large number of certain fi sh species by seine, while triggering their stress reaction at the same time.…”

“…Studies of humans (1,2) and vertebrate animals (3) demonstrate that the norm of sodium content in the internal environment is maintained within a certain narrow range (normonatremia), thus contributing to the optimal functioning of various body cells. Adverse factors reduce the level of sodium in blood plasma of humans (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19), other mammals (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31) and freshwater fi sh (32)(33)(34)(35)(36)(37) below the norm.…”

BACKGROUND: The effect of hyponatremia on the body is studied on model objects. The related question concerns the degree of compliance between manifestations of hyponatremia and protective mechanisms in humans and other species of vertebrates. OBJECTIVES: To identify the regulation ranges and patterns of adaptation to hyponatremia by cells of various organs and tissues of vertebrate animals. METHODS: To assess the regulation ranges and patterns of adaptation to hyponatremia, a comparative analysis has been applied to the data obtained from humans, mammals and freshwater fi sh. RESULTS: The physiological content of sodium in the blood plasma in humans is regulated and maintained within a narrow value range which is similar to that occurring in a number of other vertebrate species. The counteraction to hyponatremia is performed by means of accelerating the transport of sodium, potassium, chloride and organic osmolytes from the cells into the internal environment. CONCLUSIONS: The data regarding mammals are fragmented and refl ect the manifestation of protective mechanisms taking place during the initial period of hyponatremia. The method tested on freshwater fi sh allows for studying patterned changes in inorganic ions and content of organic osmolytes in the internal environment and cells of various organs and tissues of the body from the start of developing hyponatremia till the completion of the recovery process in vivo (Fig. 2, Ref. 72).

“…Metode penangkapan belut menggunakan alat setrum, dan pengumpulan belut hasil tangkapan pada wadah penampungan dengan media air tanpa lumpur menyebabkan ikan stres dan mengalami kematian (Hadiroseyani, 2016). Masalah pemeliharaan pasca-penangkapan yang menyebabkan stres juga terdapat pada ikan roach dan ikan bream (Martemyanov, 2013). Pengaruh stres pada ikan di antaranya dapat menganggu pertumbuhan, perkembangan fisiologis, reproduksi, resistensi terhadap penyakit menekan kemampuan imunitas, dan menyebabkan kematian (Schreck & Tort, 2016).…”

Belut (Monopterus albus) merupakan ikan air tawar konsumsi hasil tangkapan dari perairan umum yang dijual dalam keadaan hidup dengan harga tinggi dan permintaan yang terus meningkat. Aktivitas penangkapan, transportasi, dan penampungan menimbulkan kematian yang cukup banyak sehingga mengurangi stok dan nilai penerimaan penjualan belut. Penanganan belut pasca-penangkapan dalam air salin dapat menekan tingkat kematian belut, namun dampaknya terhadap keuntungan bisnis belum diketahui. Penelitian ini bertujuan untuk mengevaluasi penampungan dalam air salin terhadap sintasan dan keuntungan usaha penjualan belut hidup. Penelitian dilakukan pada pedagang besar belut hidup di Jawa Tengah yang memperoleh pasokan belut dari berbagai lokasi di Jawa. Belut uji yang diperoleh dari tiga lokasi yaitu Ciamis, Jawa Barat; Cilacap, Jawa Tengah; dan Lumajang, Jawa Timur; masing-masing ditampung terpisah dan dipelihara selama enam hari dalam air tawar (salinitas 0 g/L) dan air tawar yang ditambah garam krosok pada konsentrasi 6 g/L. Hasil menunjukkan bahwa penampungan selama seminggu dalam salinitas 6 g/L menghasilkan tingkat sintasan belut 1,6 kali dibandingkan dengan penampungan dalam air tawar pada semua lokasi asal belut. Sintasan yang lebih tinggi tersebut meningkatkan nilai penerimaan dan keuntungan usaha.Asian swamp eel (Monopterus albus) is a highly-priced freshwater fish collected from natural waters and sold alive in the market with an ever-increasing demand. Fishing methods, transportation, and holding of live eels before being sold frequently result in significant mortality, which eventually reduces the sales revenue from the business. However, post-capture handling of the eel using saline water could reduce the mortality rate, but the impact on business profits has never been determined. This study was aimed to determine the effects of water salinity on the survival of the eels during the holding period and calculate the profit gain from live eel sales. The research was carried out in the facility of a wholesaler of live Asian swamp eel in Central Java which received eel supply from various locations in Java. The samples of eels were originated from three locations, namely Ciamis, West Java; Cilacap, Central Java; and Lumajang, East Java. The eels were placed in separate containers filled with: fresh water (salinity 0 g/L) and freshwater added with salt at concentration 6 g/L for six days. The results showed that six days holding period in salinity of 6 g/L resulted in a higher survival rate of the eels up to 1.6 times compared to the freshwater. This higher survival has increased the revenues and profitability of the live eels sales.

“…These substances cause various damaged in the organism (Figure 1, right part), including increase in the permeability of cellular membranes. As a result, the blood passing fish gill capillary system loses ions, mainly sodium and chlorine [16][17][18][19][20][21]moving into the freshwater. This leads to the decrease in concentration of these electrolytes in the organism's internal environment [16][17][18]20,22] (Figure 2).…”
