|Population:||This species is common and widespread in the Mediterranean Sea and it has also been recorded from the western part of the Black Sea (Louisy 2005). The current population trend of this species is stable.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species lives mainly over Posidonia seagrass beds, though it is also present on algal-covered rocky reefs (Golani et al. 2006). It frequently occurs in large aggregations and feeds on small benthic organisms such as molluscs, crustaceans and echinoderms. Spawning takes place in spring, when the male builds and guards a nest of algae, in which one or more females lay adhesive eggs (Golani et al. 2006), and the breeding season seems to be from March to June (Louisy 2005). The age at maturity of this species is one year, its longevity of about 3-4 years and its maximum size is 13 cm (SL) or 14 cm (TL) (Louisy 2005, Golani et al. 2006).
This is not a migratory species and they tend to form aggregations year-round (Golani et al. 2006).
|Movement patterns:||Not a Migrant|
|Use and Trade:||This species may be sold for food when caught in local artisanal fisheries, where it is probably mainly used in fish soup.|
|Major Threat(s):||There are no known major threats to this species, although it may be utilized as food when caught in local artisanal fisheries. However, its shallow water seagrass and rocky reef habitats may be threatened with habitat degradation, as a result of urban and agricultural development and waste disposal along the adjacent coastlines, pollution (D. Pollard pers. comm. 2008) and the invasive introduced tropical algae Caulerpa taxifolia (Verlaque and Fritayre 1994, Villele and Verlaque 1995).|
There are no specific conservation measures in place for this species. Its distribution overlaps with several marine protected areas within its range. However, there is a need for conservation actions, regarding resource and habitat protection of seagrass and rocky algal reef habitats, where control of the invasive species Caulerpa taxifolia needs to be undertaken as well, enabling this way restoration of the habitats. Creation of awareness must be carried out in order to prevent water pollution, habitat degradation and control of the invasive algae species. To this matter, policies and regulations need to be strengthened.
More research is also needed regarding the species' population size, distribution and trends, life history and threats. Monitoring is also needed regarding population, harvest and habitat trends.
