Snapper, Seabream & Grunt Specialist Group
Key features of SSG SG fishes include:
- They can inhabit nearly every estuarine and marine habitat in shallow tropical through temperate areas of the globe.
- The SG includes some of the most iconic fisheries on the planet: many species are sold as “red snapper” and hundreds are regional bread-basket food species.
- Data is often very limited, yet evidence suggests that many species are subject to heavy fishing pressure, habitat loss, and climate change effects.
- As of May 2018, 68% of the SSG SG species have been assessed and published on the IUCN Red List.
- Conservation planning and actions have focused in part on protecting the spawning aggregations of heavily fished species, as well as juvenile nursery habitats.
The families in the SSG SG are basal/intermediate percoids and involve many unresolved challenges in taxonomy and systematics. Based on recent phylogenetic research, the estimated number of species in the six families are as follows:
|Seabreams and Porgies (Sparidae)||163|
|Grunts and Sweetlips (Haemulidae)||135|
|Threadfin Breams (Nemipteridae)||70|
