Title: Experimental Studies to Evaluate Larval Survival of the Fire Shrimp, <i>Lysmata debelius</i>, to the Juvenile Stage
Abstract: Abstract Many coral reefs are threatened because of anthropogenic impacts such as destructive fishing methods for marine ornamentals. The marine ornamental industry is currently almost completely dependent upon wild collections. The development of commercially feasible methods to culture ornamental species could help to reduce the need for wild‐collected specimens and reduce pressure on coral reefs. Advances in larval rearing and nutrition would help overcome the bottlenecks that impede the commercial production of many marine ornamental species. This article focuses on research for improving the production of the fire shrimp, Lysmata debelius . Experiments were performed with larval fire shrimp to evaluate (1) the importance of essential fatty acid enrichment of live prey (rotifers and Artemia ) and (2) feeding penaeid shrimp muscle tissue to improve survival to metamorphosis. We also provide the fatty acid composition of Day‐1 posthatch fire shrimp larvae. The enrichment of live prey with docosahexaenoic acid did not improve larval growth, survival, or time to metamorphosis, but larvae fed live prey together with pureed penaeid shrimp muscle had survival rates of 9.8 ± 1.2%. The data and protocols developed in this study provide a foundation and baseline for future fire shrimp larval studies.
