Promising results in Saint Martin !

The Association of Management of the Natural Reserve of Saint-Martin continues its surveys of larval colonization on the shallow coastal bottoms of the island of Saint-Martin with the method of sampling by light devices. This second capture session is very positive: groupers in the samples !!! At least two species. They are growing on a breeding farm to confirm the species before being released. Suspense!

The PCC

PCC (Post-Larval Capture and Culture) is a technique for capturing and cultivating marine post-larvae. The post-larval fish is the last larval stage of their ocean life cycle. In the vast majority (more than 95%) these post-larvae disappear by natural predation. The PCC therefore consists in taking these larvae before this high mortality in order to reinforce the populations of fish. This study makes it possible to know when and which species settle in the coastal waters of the island.

ECOCEAN

ECOCEAN, partner of the AGRNSM, returned to the island during this February session to train the agents of the Nature Reserve in another study technique: artificial nurseries (#BioHut) established around the island to study the species that settle there. Some had already been installed during the first run of ECOCEAN last October and counts have been made.
Again, the results are good: small Nassau groupers have been observed in BioHut!

BioHut

BioHut are artificial nurseries, small habitats installed to allow young larval stages to find food, hide from predators and grow properly.
