Abstract
In this study we observed the influence of royal jelly on sex reversal in zebra fishes (Danio rerio). Experiments were made in the laboratories of aquaculture from Faculty of Animal Science and Biotechnologies, Timișoara in the period 01.03.2010 – 15.05.2010 on 225 individuals. The dinamics of standard body weight, the standard length and the maximum body high at all individuals from tree experimental variants were evaluated. It was indentified the number of males and females by direct examination of the body and microscopic observation of histological samples. In the first experimental variant the food was mixed with 0.02 g powdered royal jelly and recorded at the end of the experiment 70.76% females and 29.24% males. In the second experimental variant, a double dose of powdered royal jelly was mixed in the feed, this leading to the increasing of females in the group to 81,19%. In the control variant the percentage of females was 50.7% and the percentage of males was 49.3%.

Effect of astaxanthin and cholesterol on growth, survival, and pigmentation of adult spiny lobster, Panulirus ornatus (Decapoda, Palinuridae).
Prior research on the spiny lobster Panulirus ornatus (Fabricius, 1798) determined that intermediate levels of cholesterol are important in diets, but astaxanthin may not be. Here we examined how the growth, survival and...
