Abstract: (650 Views) |
Dynamic energy Budget (DEB) theory describes the rate of energy absorb by living organisms and use it for body protection, growth, and reproduction. The present study was performed on Alburnoides eichwaldii in Zarrin-Gol and Kaboudwal rivers (Golestan province). The results showed that the DEB growth model in the two rivers and the allocation of energy fraction for body maintenance (κ) was more than 0.9, which indicates the high growth rate and short lifespan of this species. Maximum surface specific-area assimilation rate {pAm} in Kabudwal river fish is about three times that of Zarringol River. Somatic maintenance based on body volume, pM for Zarringol River is about 3 times and the maximum reserve density[Em] is about 5 times less than Kabudwal. In Addition, maturity at birth EHb , In Zarringol river was less than Kabudwal and maturity at the time of reproduction EHp in Zarringol river was more than Kabudwal but its size was bigger at maturity in Kabudwal river. On the other hand, the higher energy conductivity ϑ  in A. eichwaldii in Zarringol River was due to its low energy density, and this fish in Zarringol River needs less energy to somatic maintenance. The DEB standard model is superior to other models in that it is able to provide quantitative and measurable descriptions for the aspects of individual and population metabolism of animals.
