The database comprises the distribution of freshwater fish species in 28 Italian lakes. Data were obtained between 2007 and 2014 from standardised (CEN based) samplings with benthic and mesopelagic multi-mesh gillnets. The database offers a detailed description of the biodiversity of fish communities in the Italian regions of Piedmont, Lombardy, Trentino-Alto Adige and Sardinia including both natural lakes and reservoirs.
short description of the dataset/summary (original/national language):
Il dataset include le informazioni sulla distribuzione della fauna ittica in 28 laghi italiani. Le informazioni raccolte sono basate su campionamenti con reti multimaglia bentiche e pelagiche in accordo con la metodologia CEN e il protocollo nazionale utilizzato per l'applicazione della Direttiva Quadro sulle Acque 2000/60/CE.

sample specifications:
specification of method(s) used for sampling and sorting:
According to the depth and surface area of the lake, an appropriate number of benthic and pelagic multi-mesh gillnets were used, following CEN standards partly modified. Each benthic net was 40 m long and 1.5 m high and was composed of 16 panels (each 2.5 m long) with mesh sizes ranging from 5.5 to 135 mm. The benthic nets were set from the surface down to 100 m depth. Pelagic sampling was performed with a variable number of nets linked together, each being 27.5 m long and 6 m high and having 11 panels (with a mesh size ranging from 8 mm to 55 mm, knot to knot). Four additional nets (40 m long, 6 m high, 4 panels (75, 95, 115 and 135 mm)) were attached to the end of each pelagic net set. The nets were set at 10 m intervals from the surface down to 50 m depth. Nets were set at dusk between 16.00 and 20.00 pm and lifted the following morning between 06.00 and 08.00 am.
