Estonia-specific ICES landing statistics are available from 1991-2007, and these form the reported data baseline, to which we added disaggregated data from the USSR period for commercial landings as well as estimates of unreported commercial landings, discards, and recreational catches. Over the entire study period (1950-2007) the total reconstructed catch was estimated at 5.8 million tonnes. Our reconstruction for the period when ICES landings statistics are available for Estonia (1991-2007), yielded a cumulative catch of approximately 1.5 million tonnes. This is 300,000 t larger than the landings attributed to Estonia by ICES during this period. Our approach indicates that total catches since 1991 were approximately 28% higher than given by ICES, yet we believe this reconstruction represents a conservative estimate. The main species targeted by the commercial fisheries are cod (Gadus morhua), herring (Clupea harengus), and sprat (Sprattus sprattus). INTRODUCTION Estonia is a small country (45,100 km 2 ) on the eastern edge of the Baltic Sea with a population estimated as 1,347,000 in 2005 (UN, 2008), which comprises approximately 0.46% of the total Baltic population. Estonia, which declared its independence from the USSR in August 1991, shares a border to the south with Latvia and an eastern border with the Russian Federation (Figure 1). Estonia has a 12 nautical mile territorial limit (within which only nationals are licensed to fish), although Estonian fishers have access to areas beyond this boundary (FAO, 2005). In recent years, the most important fisheries species have been herring (Clupea harengus), sprat (Sprattus sprattus), and Atlantic cod (Gadus morhua). Estonia‘s fisheries can be divided into four segments: 1) Baltic open-sea fishing (trawling); 2) Baltic coastal small-scale fishing (using passive gears); 3) Distant Water Fleet fishing in the Atlantic; and 4) inland freshwater fishing.
