The IUCN SSC Snapper, Seabream, and Grunt Specialist Group (SSG SG) works to globally advance research and conservation of over 540 diverse reef and estuarine species in six families of marine fishes, more information on these families is below the slides.
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 March 2019, approx 78% of the SSG SG species have been assessed and published on the IUCN Red List.
- The taxonomy of some lineages is still unresolved, the March 2020 list of species by family for all six SSG SG families is available on the SSG species 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:
|Family||No. species||No. Red Listed||% Red Listed|
|Seabreams and Porgies (Sparidae)||166||134||80.7|
|Grunts and Sweetlips (Haemulidae)||136||99||72.8|
|Threadfin Breams (Nemipteridae)||73||42||57.5|
