RNA/DNA ratio analysis (R/D) is used as a quick and efficient tool to determine fish growth status. Therefore, this study aimed to estimate the R/D ratio in larvae produced from crossing of three females with three wild male sturgeons Acipenser persicus breeders caught from the southern shores of the Caspian Sea in Guilan province were done in a 3×3 factorial experimental design. Nine treatment...
Since chemical methods so far proposed for vitamins D determination commonly suffer from coexistence of interfering substances and hence from requirement of designing tedious purifica tion steps, a more simple analytical procedure without such pre-treatment has been strongly desired. During the course of our study on a gas-liquid chromatographic determination of vitamins D (1), efforts were als...
