meeting dolphin fish

The tropical ocean is especially well-known for the extraordinary biodiversity of its coral reefs, but corals are only rare oases of life compared to the immense expanses of ocean.

Pelagic fish live in this blue desert, without any fixed home or territory.

Any object floating on the surface of the ocean - logs, cans, plastic bags, ropes - can become a meeting place for this species.

Scientists call this behaviour «aggregation».

We still have no satisfactory explanation for this phenomenon of aggregation. In order to study it, IFREMER’s Fisheries Research Laboratory in La Reunion chose the dolphin-fish as a biological model for these aggregations.
