Abundance and biomass of macrofauna taxa at observation locations FI_WELFIN_XLIV (35 m) and FI_WELFIN_XXVI (20 m) from 1966 to 2017. Data is missing for years 1980-1983 at FI_WELFIN_XLIV and for years 1975, 1982 and 1986 at FI_WELFIN_XXVI.

Data were collected at different type specific sites situated at upper, middle and low part of the Mesta River. Physicochemical data (oxygen concentration, water temperature, pH, conductivity and biogens) were taken during 2012. At that time were collected macrophytes, macrozoobenthos, phytobenthos and fishes samples.

Soft bottom and hard bottom habitats within the BB0000146 'Gradina-Zlatna ribka' SCI area. Mapped and created by IBER-BAS within the BalkanMed RECONNECT project (2017-2020).

The introduction of non-indigenous species (NIS), also known as alien species, is a pressing issue throughout the world nowadays, mostly linked to globalization. Transitional environments are particularly exposed to this threat due to the importation of seafood for either aquaculture or sale. According to the most recent observations, the Mar Piccolo of Taranto hosts 36 NIS positively identified, divided in 13 invertebrates, 15 macroalgae, and 8 planktonic species. This basin ranks third among the Mediterranean hot spots for seaweed introduction, after the Thau Lagoon (southern France) and the Venice Lagoon. Continuous monitoring activities are carried out to early identify new introductions and follow the fate of those already introduced.
