Blood trials had been collected and you may reviewed to have solution calcium supplements and you will phosphate accounts by the types of Trinder (1960) and Fiske and Subbarow (1925), correspondingly. Gonads were fixed to guage the condition of growth of your seafood. Guys showed no change in solution calcium levels throughout the year for the correlation with testicular growth. not, gel phosphate levels demonstrated a rise in correlation towards the improved gonadosomatic directory. Lady exhibited marked regular changes in solution calcium and you will phosphate profile which were regarding the ovarian maturation (vitellogenesis).
Annual alterations in gel calcium and you can inorganic phosphate accounts and you may relationship that have gonadal standing regarding a beneficial freshwater murrel, Channa punctatus (Bloch)
Blood trials was in fact gathered and reviewed to possess solution calcium supplements and phosphate levels from the methods of Trinder (1960) and you will Fiske and you may Subbarow (1925), respectively. Gonads was fixed to evaluate the condition of maturation of the seafood. Guys presented no change in solution calcium profile year round when you look at the relationship which have testicular growth. Although not, gel phosphate account exhibited an increase in correlation on increased gonadosomatic index. Lady presented marked regular alterations in serum calcium and you can phosphate membership that happen to be with the ovarian growth (vitellogenesis).
Vitellogenesis involves hepatic formation off yolk proteins (vitellogenin) and you will raises blood vitellogenin articles followed by deposition out of one or two models regarding yolk from the ovary: yolk vesicles (mucopolysaccharides) and you can yolk granules (phospholipoproteins). “But not, couples degree describe the partnership anywhere between bloodstream phosphate top and gonadal maturation inside fishes (seven,20)” の続きを読む
