Coral reef fish species are an important source of food for the 70% of Venezuela's population that is concentrated in coastal areas, and there are concerns about the effects that the world's largest oil and gas development will have on the country's reefs. Rather than repair environmental damage caused by the development of marine resources, it is easier and more economical to formulate a crisis management plan to effectively manage any situations. Continuous monitoring in order to discover any impact on ecosystems at an early stage is crucial for this method. This project aims to conduct a short- to medium-term investigation into the biological and chemical conditions of reef ecosystems using a variety of observation tools in order to assess the impact of oil development. Specifically this means monitoring living organisms (benthic organisms, fish species), chemicals (chemical properties in water and sediment), and biomarkers (stress enzymes and hydrocarbon detoxicants) in the Los Roques Islands National Park.
