Abstract

Experiments were conducted to determine what effects the presence of petroleum residues and the associated petroleum-degrading bacteria have on the development and survival of the larvae of the brown shrimp Penaeus aztecus. Larvae were exposed to south Louisiana crude oil, Kuwait crude oil, #2 fuel oil and eight species of oil-degrading bacteria from the genera Pseudomonas and Vibrio. Shrimp larvae exposed to #2 fuel oil, the oil-degrading bacteria or combinations of petroleum and bacteria exhibited 100% mortalities within a few hours. Larvae exposed to the two crude oil developed slowly and died after reaching the first protozoea stage. Control larvae developed normally to postlarvae with survival rates consistently above 85%.
