    Historical landings from the Venice (Italy) fish market for the period 1905-1927 (with some temporal gaps) were retrieved and transformed into workable spreadsheets from statistical bulletins published by the Municipality of Venice, the "Società regionale veneta per la pesca e l'acquicultura" (Veneto regional society for fisheries and aquaculture) and by the historical scientific journal called "Neptunia".

    Historical landings from the Rijeka (currently Croatia) fish market for the period 1914-1932 were digitised from D’Ancona (1926). At the time, the Rijeka fish market was one of the most important in the area together with Trieste (currently Italy) and Venice (Italy). These fish markets collected almost all fish caught in the Northern Adriatic Sea at time.

A dedicated aerial survey methodology, following standard protocols, was preferred to ship surveys. The general design corresponds to published protocols prepared for small cetaceans, but data for other marine mammals (large whales, sirenians), seabirds, sea-turtles, large teleosts and large elasmobranchs) are collected as well.

    Original provider: Duke Marine Robotics and Remote Sensing Lab Dataset credits: Duke Marine Robotics and Remote Sensing Lab Abstract: These RGB mosaics and thermal indices of Atlantic grey seal colonies at Hay and Saddle Island, Nova Scotia, were collected by small unmanned aircraft systems (UAS). The mosaics and thermal indices were assessed by human analysts, who counted the seals in the mosaic and classified individuals as 'young of the year' or 'adult'.

    Italian annual landings (1953–2012) for the Northern and Central Adriatic Sea originated from official Italian statistics on the fishery, reported by the Italian National Institute of Statistics (ISTAT) from 1953 to 2004, and by the Institute for Economic Research in Fishery and Aquaculture (IREPA) from 2005 to 2012.

    The dataset was obtained from the original registers of the fish markets of Venice and Chioggia that were available on paper documents from 1945 to 1996, and in electronic spreadsheets from 1997. The data originally included information on landings from aquaculture and sea- and lagoon-fishery merged together.

    Historical landings from the Trieste (currently Italy) fish market for the period 1902-1968 (with some temporal gaps) were retrieved and entered in a digital format from the official statistical bulletin (paper format) of the Municipality of Trieste. At that time, Trieste fish market was one of the most important in the area together with Rijeka (currently Croatia) and Venice (Italy).
