Procjena energetske bilance artemije jezera Uremia i metode njezine optimizacije

Abstract

In this study, an energy balance sheet was evaluated for the production of artemia in the Fasandoz plain of Miandoab. The research was done in 8 earthen ponds, with 2 ponds of 0.7 hectares and 6 ponds of 0.3 hectares. According to the results of the semi industrial research center in the Fasandoz plain in western Azerbaijan province, sampling shows that the biomass of artemia average 40 tons per year. According to the energy efficiency of the cyst and adult artemia compounds, the energy balance sheet is calculated as a function of biomass and protein. The amount and energy efficiency (ratio of data to saving) is estimated as a function of biomass as 0.048, and as a function of protein as 0.018. The most consumed energy is in response to application of hen fertilizer (47.74 percent) and gasoline (29.4 percent), and the least energy is consumed as required for releasing cysts (0.001). To produce brine shrimp in Uremia Lake, the bisexual Artemia urmiana should be used. Recommendations are provided for the optimal consumption of energy harvest of cysts in artemia breeding pools. In ponds designed to produce artemia, a large amount of lime should be added in the preparation stage, to increase the alkalinity of the water, such that with frequent fertilization until the end of the cycle, there is no reduction of pH in the water. The results indicate that at high salinity, artemia populations will decrease in the ponds and fewer cysts will be produced. Cytogenesis of Artemia urmiana occurs at low temperatures, such that cytogenesis should not be attempted during warm seasons.U radu je procijenjena energetska bilanca proizvodnje artemije na visoravni Fasandoz u području Miandoab. Istraživanje je obavljeno u 8 zemljanih bazena, dva površine 0,7 ha i šest površine 3 ha. Rezultati uzorkovanja industrijskog Istraživačkog centra na visoravni Fasandoz u zapadnoj azerbejdžanskoj provinciji pokazuju da proizvedena godišnja biomasa artemije prosječno iznosi 40 tona. S obzirom na energetsku efikasnost komponenti cista i odrasle artemije energetska bilanca je izračunata kao funkcija biomase i proteina. Količina i energetska efikasnost procijenjena je kao funkcija biomase na 0,048, a kao funkcija proteina na 0,018. Najveći postotak utrošene energije je zabilježen pri upotrebi kokošjeg gnojiva (47,74%) i benzina (29,4 %). Također su date preporuke za optimalnu energetsku iskoristivost cista artemije u uzgojnim bazenima. U pripremnoj je fazi potrebno koristiti velike količine vapna u zemljanim bazenima dizajniranim za uzgoj artemije kako bi se povećao alkalinitet vode i time do kraja ciklusa onemogućio eventualni pad pH izazvan frekventnim gnojenjem. Rezultati pokazuju da se pri visokom salinitetu brojnost populacije artemije i proizvodnja cista smanjuju. Do citogeneze Artemia urmiana dolazi pri niskim temperaturama, te ona ne može biti postignuta za vrijeme tople sezone
