The majority of these wild-caught imports to the USA are from 10 countries:

China, Thailand, Indonesia, Ecuador, Canada, Viet Nam, the Philippines, India, Mexico, and Chile. For all the countries that exported catch into the USA in 2011, freshwater, ATM/ATR inhibitor cancer non-edible, and declared farmed seafood product catches were excluded from total catches to get estimated total imported marine capture [17]. These top 10 countries (out of a total of around 120 countries exporting fish products to the U.S. that year) represented approximately 80% of 2011 seafood imports to the USA by volume and value [18]. Total imports of edible seafood products to the USA in 2011 were 2,379,940 t, valued at $16.5 billion. Seafood imports from the top 10 countries exporting to the U.S. were 1,914,610 t of edible seafood products valued at US$13 billion. The 30 products examined for this study (see below) represented about 45% of U.S. 2011 wild-caught seafood imports by volume; NOAA estimates that about half of total imports are from aquaculture. Estimates of the total level and value of illegally caught fish

entering the market in the USA as imports are estimated using the following scheme, as illustrated in Fig. 1. 1. For each of the top 10 countries as sources of imports, the top three wild-caught seafood products (by species groups find more and volume) exported to the United States were identified, resulting in 30 import streams identified by country and species group. The species groups were defined by the statistical

categories available in the NMFS trade database. In two cases (Ecuador and Mexico), the top three products exported to the USA included shrimp. Since data from NMFS do not distinguish wild from farmed shrimp, additional analyses were performed to estimate the proportion attributable to wild shrimp in each case. Previously published analyses [19], [20], [21] and [22] have established the “anchor point and influence” methodology to examine illegal and unreported catches. This method is adapted to focus on illegal and unreported catches for oxyclozanide specific fisheries from which products were exported to the United States in 2011. A brief explanation of this methodology is as follows: First, empirical data from a wide variety of sources were used to establish “anchor point” estimates of the upper and lower bounds of illegal and unreported fishing in each fishery. Monte Carlo simulations were used to investigate the effects of uncertainty, with 1000 simulations across the distribution of uncertainty. The estimates are presented with a 95% confidence interval. Qualitative and quantitative data were subsequently used to generate “influence factors” that then scale the interpolations between anchor point estimates.
