Peppermint shrimp molt8/4/2023 ![]() ![]() The crustaceans of the genus Lysmata are species of particular interest to the marine aquarium market ( Wabnitz et al., 2003 Bruckner, 2005), and there have been several efforts to develop biotechnologies for the cultivation of species of interest to meet worldwide demand. The interest in the production of ornamental marine invertebrates has increased in recent years due to their growing demand and price by the marine aquarium market ( Leal et al., 2015). Keywords: Lysmata wurdemanni ornamental shrimp carotenoids egg quality ![]() The results indicate that both sources of carotenoids promote survival and growth and improve egg quality and pigmentation. A negative correlation (R 2 = −0.93) was recorded between increasing dietary astaxanthin and body accumulation in contrast, an increase in dietary β-carotene was positively correlated (R 2 = 0.80) with body accumulation. The greatest quantity of molts and ovigerous female were observed in the A(1) and A(1.5) groups besides, the eggs of the females in A(1) that had the highest protein and energy content. The survival of the shrimp was similar in both astaxanthin and β-carotene treatment groups however, in both treatment groups was significantly higher than the control group, while growth was similar in all treatments. After 105 days of culture, the survival, weight gain, number of molts and gravid female, protein, energy content of fertile eggs and the carotenoid content in cephalothorax and abdomen of the shrimp per treatment group were recorded. ![]() Six treatments: A(0.5), A(1), A(1.5), B(0.5), B(1) and B(1.5), and a control group were evaluate with three replicates and five post-larvae (initial weight 0.03 ± 0.007 g) per replicate. The effect of the incorporation of three different concentrations (0.5, 1 and 1.5%) of either astaxanthin (A) or β-carotene (B) was evaluated during the feeding of peppermint shrimp Lysmata wurdemanni post-larvae with six isonitrogenous (34%) and isolipidic (8%) diets. ![]()
