Protecting threatened Over-seas biodiversity

Scientific monitoring favorable to management

Since May 2020, GEPOG has welcomed Noémie SALIBA in the final year of a DUT in biological engineering with an environmental engineering option at the IUT of Digne-les-Bains to carry out a 4-month internship and focus on the component aimed at concerted management and of the Atlantic goliath grouper in French Guiana.

Critical study results

Since the proper management of marine resources must be based on a sufficient level of knowledge of the species, Noémie therefore takes stock of the scientific studies carried out on the Atlantic Goliath Grouper in Guyana. She first wrote the synthesis of the methods used and the results obtained during the thesis work of C. Artéro (between 2010 and 2014) on the Atlantic Goliath Grouper in Guyana and which aimed to describe biology and ecology of the species.

Several files describing the work will soon be available online (external marking, monitoring by satellite beacons, gamete samples, etc.). In collaboration with Jules Chiffard, biostatistician in Montpellier, she also analyzes more than ten years of scientific data collected on the Atlantic goliath grouper by the CMR (Capture-Marking-Recapture) method. Its objective is to study the demographic trend of the Atlantic goliath grouper population in Guyana and to determine the effectiveness of the CMR method in our context. The database includes more than 800 groupers tagged at 4 main fishing sites.

Concrete tools

At the end of her internship, she will produce a report that will include all of her work as well as guidelines for the pursuit of actions and the establishment of scientific protocols to answer the questions necessary for the proper management of the species in Guyana.

At the same time, it ensures the compilation of pleasure fishing charters and regulatory texts that frame this practice in order to envisage the production of a guide to good practice.
