Beached fulmars, collected by volunteers throughout the Netherlands, are dissected at IMARES Texel. The standard methods include records of many external and inte rnal charact ers that can indicate the age, sex, body – con dition, origin, breeding status, cause of death , etc., all variables that might be relevant in later specific data analyses.
Commissioned by the Netherlands Ministry of Infrastructure and the Environment, IMARES has published its new monitoring report on quantities of plastics in stomachs of Northern Fulmars found on Dutch beaches up to year 2013.
The added two years of data suggest a decrease in quantities of plastics, but are not significant over the past ten years. Currently, 94% of investigated stomachs of Dutch Fulmars contained one or more plastic particles, and about 52% contained more than the critical level of 0.1 gram plastic. North Sea governments have set a policy target where this percentage is reduced to below 10%.

To quantify the occurrence of ingested plastic in fish species caught at different geographical positions in the North Sea, and to test whether the fish condition is affected by ingestion of plastics, 1203 individual fish of seven common North Sea species were investigated: herring, grey gurnard, whiting, horse mackerel, haddock, Atlantic mackerel, and cod. Plastic particles were found in 3.2 % of the examined fish and in five of the seven species. In most cases only one particle was found per fish, ranging in sizes from 0.04 to 4.8 mm, with a median size of 0.6 mm. The frequency of fish with a plastic particle was significantly higher (7.2%) in the southern North Sea, than in the northern North Sea above 55°N (1.3%). The highest frequency (>33%) was found in cod from the British Channel. In addition, small fibres were initially detected in most of the samples, but their abundance sharply decreased when working under special clean air conditions. Therefore these fibres were considered to be artefacts related to air born contamination and were excluded from the analyses. No relationship was found between the condition of the fish and the ingested small plastic particles.
