Article
A mass balance model of the marine ecosystems is presented for the four prefectures of Japan prior to the Great East Japan earthquake. The Ecopath with Ecosim food web modelling approach and its Ecotracer routine were used to simulate the concentrations of ¹³⁷Cs in the ocean and the biota in order to serve as baseline, , and to estimate the initial...

Tritium of artificial origin was initially introduced to the environment from the global atmospheric fallout after nuclear weapons tests. Its level was increased in rainwaters by a factor 1000 during peak emissions in 1963 within the whole northern hemisphere. Here we demonstrate that tritium from global atmospheric fallout stored in sedimentary re...

During the 1980s-90s, the contamination of the Mediterranean Sea by radionuclides was widely studied following the Chernobyl accident and the recognition of the influence of Rhône discharges. At this time, numerous in situ or laboratory studies were conducted to evaluate the behavior of radionuclides in trophic chains and in the water column. For v...
Article
Quantitative Seascape Ethnoecology practice is considered through a community-based food security lens. Fish and marine mammal records obtained from a wide range of Inuit co-management agreements are, for the first time combined to calculate an Inuit-culture marine ecological footprint, targeted on calendar year 2008. A reflexive, participatory and...

We present a global dioxin model that simulates one year of atmospheric emissions, transport processes, and depositions to the earth's terrestrial and marine habitats. We map starting emission levels for each land area, and we also map the resulting deposits to terrestrial and marine environments. This model confirms that 'hot spots' of deposition...

The Amerasian Arctic, covering northern Siberia (Russia), Arctic Alaska (USA), and the Canadian Arctic, extends over seven coastal Large Marine Ecosystems and makes up the seasonally ice-free part of FAO Statistical Area 18 (Arctic Sea). Historically, the harsh climate has limited marine fisheries (here excluding marine mammal hunting) to small-sca...

We estimated the total marine and brackish-water fisheries catches from the Baltic Sea Large Marine Ecosystem, from 1950-2007, taken by and Sweden. Using the ICES electronic catch database as the ‗reported data' baseline, we added several IUU (Illegal, Unreported and Unregulated) catch components: ‗adjustments' (data source adjustments to the repor...

Total marine fisheries catches in the Baltic Sea by Poland were estimated from 1950-2007 using a method called ‘catch reconstruction’. Using ICES landing statistics (which have included Polish catches since 1955) as our reported data baseline, we created a more comprehensive catch-data time-series that accounts for ‘adjustments to ICES landing stat...

Timor-Leste (East Timor) became an independent country at the close of the 20th century, and thus the FAO‘s fisheries division only presents catch data for Timor-Leste from 1999 onwards. However, as a former colony of Portugal and afterwards, as a province of Indonesia, the fisheries sector was described in various technical reports. Here, we prese...
Article
The bottom-fish stocks of the Main Hawaiian Islands (MHI) are intensively fished, both commercially and recreationally. Recent assessments of the Bottomfish Management Unit Species (BMUS) complex suggested overfishing, and expressed concerns about missing non-commercial data. We used reported commercial time-series data and estimation ratios to ind...
Chapter
Full-text available
We present a rationale for the description and diagnosis of fisheries at the level of Large Marine Ecosystems (LMEs), which is relatively new, and encompasses a series of concepts and indicators different from those typically used to describe fisheries at the stock level. We then document how catch data, which are usually available on a smaller sca...
Article
Nearshore fisheries in the tropical Pacific play an important role, both culturally and as a reliable source of food security, but often remain under-reported in statistics, leading to undervaluation of their importance to communities. We re-estimated nonpelagic catches for Guam and the Commonwealth of the Northern Mariana Islands (CNMI), and summa...
Article
Full-text available
Fisheries catches from Pacific Island coral reefs are rarely recorded in official statistics. Reconstruction of catch estimates with limited hard data requires interpolation and assumptions, justifiable only by the unsatisfactory alternative of continued substitution of zero catches, a common policy interpretation for ‘no data’. Uncertainties assoc...
Article
Full-text available
In developing countries, official statistics, national accounts, and economic development initiatives generally focus on commercial, often export-oriented fisheries, which are often perceived to be the major economic contribution of fisheries. While small-scale, non-commercial fisheries, especially near-shore subsistence fisheries, have been recogn...

Article
Mercury is known to have detrimental effects on human health ([1][1]), so it is surprising to read that it may not be worthwhile to regulate mercury releases from U.S. power plants (“Regulating mercury: what's at stake?”, T. Gayer, R. W. Hahn, Letters, 8 July, p. 244). Although there is

We modeled the flow of methyl mercury, a toxic global pollutant, in the Faroe Islands marine ecosystem and compared average human methyl mercury exposure from consumption of pilot whale meat and fish (cod, Gadus morhua) with current tolerable weekly intake (TWI) levels. Under present conditions and climate change scenarios, methyl mercury increased...

The purpose of this report is to present a brief overview of the Bermuda fisheries and to adjust the Sea Around Us Poject (SAUP) catch database to recognize differences between more detailed national datasets and the aggregated data reported to FAO- FISHSTAT. These changes modify the species composition of Bermuda's fisheries catches starting in th...

We estimated the total marine fisheries catches taken by Estonia (including the USSR period) in the Baltic Sea from 1950-2007 using an approach called 'catch reconstruction'. 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...

Full-text available
Catch data for the northeast Atlantic with an emphasis on Norwegian fisheries are provided. The focus is on discards, by-catch, unreported, misreported and unallocated catches. Sixteen commercial fish and invertebrate species are represented with unreported catches exceeding 25% of the total catch for five of these species. Particular emphasis is d...

Using the Ecotracer routine in the Ecopath with Ecosim modelling software to estimate whole body concentrations by tissue type for the biota in Lancaster Sound. Estimated tissue concentrations will then be used to assess the potential exposure levels to mercury (organic and inorganic) for the three communities in Lancaster Sound and compare them to the World Health Organization's provisional tolerable weekly intake levels.
