Title: Biological study of increasing vitellogenin level and gonado somatic index by laserpuncture exposure at any protein level of dietary on catfish broodstock (Clarias sp.)
Abstract: This biological study aims to determine the effect of laserpuncture exposure and protein level of dietary on vitellogenin level and GSI. Three protein levels (30%, 35% and 40%) of dietary were given to the female catfish broodstock along with and without laserpuncture treatment. Laserpuncture exposure was on 2/3 ventral part of the body in 15 sec/week during 8 weeks. We used 172 of mature female catfish broodstock around 1-1.5 years old with 900-1500 grams of body weight. Blood and gonad were taken from 4 samples per treatment group in each week. Vitellogenin level was analyzed by ELISA. This study showed that laserpuncture exposure along with any protein levels of dietary, significantly increases vitellogenin level (P<0.001) and GSI number (P<0.05). Laserpuncture exposure and 30% protein dietary treatment at third week are most effective to increase vitellogenin level and GSI. It suggested that laserpuncture exposure along with 30% protein level of dietary accelerates gonad maturation 3 weeks faster.
