Goliath Grouper Preservation

Fish2_asset

A grouper needs you!

The Goliath Grouper is a close relative to the White Grouper. It is a large fish, belonging to the Serranidae family. Two Groupers are new arrivals at SEA LIFE Porto and our next Preservation campaign will be on behalf of this incredible animal that, for being so friendly and sociable, is in serious danger of extinction!

They’re so expressive that sometimes they seem to watch us on purpose! They live at shallow depths, between 3 and 200 meters (10 and 650 feet), which makes them particularly vulnerable fishing. Although they are already scarce in many seas, we can still find many specimens in the Azorean waters.

One of the greatest threats facing the Grouper is fishing for juveniles.
The Grouper is a protogynous hermaphrodite fish, which means that they live initially as females, transforming into males, when they reach a certain length. But for that to happen, in order to allow the reproduction of the species, there must be a small population of individuals of considerable size. If in a population of Groupers there are no juveniles, females may never get to become males, which in theory brings into question the viability of their population.

The slow development of the Goliath Grouper makes their populations particularly vulnerable to overexploitation. Actions such as setting minimum sizes for capture, the establishment of closed seasons during which it is not permitted to capture, and the creation of reserve areas in which it is not allowed to catch them, are vital for the preservation of this species.
In the Azores, it is forbidden to spearfish for Goliath Groupers under the Regional Legislative Decree No. 5/85/A of May the 8th, 1985. In addition, this species is also protected under the Berne Convention.

In our Campaign for Environmental Education and Ecological Knowledge, besides the dissemination of information on the Grouper, their habits and behaviours and risks that it is exposed, we alert our visitors to small daily gestures that may contribute to the conservation of Goliath Groupers and other species, equally endangered.
