A report on the remarkable site of the Grand-Connétable Island Nature Reserve

The Grand-Connétable Island Nature Reserve is located in French Guiana, about fifteen kilometers from the Approuague River. It stands out for its silhouette and today represents a sanctuary for seabirds and marine biodiversity. The reserve is home to emblematic species of Guyana, such as the Atlantic Goliath Grouper or the Green turtle, but also a multitude of fish species representative of the shallow waters of the Guyanese coast.

To raise awareness of this biodiversity hotspot, Pierre-Olivier Pradinaud, producer and director for the Tic Tac Prod company, therefore accompanied the officers of the Reserve during a scientific day of Atlantic Goliath Grouper fishing. His report will soon be broadcast in Les témoins d’Outre-mer, a program broadcast by France 3.

The first scientific fishery of the year to monitor the sizes of the Atlantic Goliath Grouper populations

Scientific fisheries for Atlantic Goliath Groupers are part of the management plan of the Grand-Connétable Island Nature Reserve. They make it possible to monitor the sizes of the populations present on this site. Twenty-three Atlantic Goliath Groupers were measured during this scientific fishery on Saturday, September 12. The largest Atlantic Goliath Grouper captured measured 157cm in length at the curve and 105cm in circumference, for an estimated weight of 95kg. The smallest Atlantic Goliath Grouper captured measured 84cm in curve length and 60cm in circumference, for an estimated weight of 30kg.

During these scientific fisheries, every precaution is taken so that the Atlantic Goliath Groupers can leave in the best conditions after being released. They are fished using a barbless circle hook that attaches to the jaw of the fish and can be easily unhooked, without harming the fish and affecting their vital organs. The handling is painless for the animal and the operation takes place in a few minutes so that the fish is returned to the water as quickly as possible.

The involvement of volunteer recreational fishermen in the project

To carry out these scientific fisheries, GEPOG association called on volunteer recreational fishermen who provide significant technical support to the mission. These fishermen, used to catching and releasing Atlantic Goliath Groupers, particularly in the context of fishing competitions, agree to share their know-how and participate fully in the smooth running of these scientific fisheries. Their voluntary participation is a way of involving them in the sustainable and concerted management of the species. In addition, three other scientific fisheries must be organized before the end of the year and other recreational fishermen will be asked to participate.
