AbstractUkraine’s marine fisheries catches were re-estimated for the 1950-2010 time period using a reconstruction approach which estimated all unreported fisheries removals, i.e., catches from the industrial, artisanal, recreational, and subsistence sectors, as well as discards from major fisheries. The reconstructed total catch for the 1950-2010 time period is 1.4 times the data we deemed officially reported on behalf of Ukraine to the FAO, which included only industrial landings. Reconstructed catches consisted to 71% of industrial, 11% artisanal, 8% recreational and 7% subsistence landings, while discards accounted for 3%. Total catches increased from about 50,000 tin 1950 to a peak of about 175,000 t in 1988, then declined with the collapse of the Soviet Union to about 55,000 t in 1991, also due to an invasion of ctenophores in the Black Sea. In 2010, total reported marine landings for Ukraine were about 70,000 t, while the reconstructed total catch was just over 110,000 t. Major unreported species were Mediterranean horse mackerel (Trachurus mediterraneus), gobies (Gobiidae), whiting (Merlangius merlangus), and bluefish (Pomatomus saltatrix). Accounting for all fisheries removals should help to establish a reliable baseline, better understand the fisheries, and thus assist management.
