Pomatoschistus minutus in the Sylt Rømø bight in 2007

Due to changing temperature regimes in the North- and the Wadden Sea, a fish survey in the Sylt Rømø bight (SRB) was established in 2007 for at least ten years. The aim is to investigate the Wadden Sea fish fauna with special interest in changes of migration behavior, species composition and feeding habits. Seven stations are sampled monthly inside the SRB. Two additional stations, one outside the bight, one close to the Danish border are sampled as references four times a year. For sampling a mini bottom trawl, total length 17 m, trawl opening 7 m, height 3 m with a mesh size of 36 mm in the wings, 16 mm in the mid part and 6 mm in the cod end is used. At every station one haul in the water column and another at the bottom are sampled, for 15 minutes at a speed of approximately 2 knots. The data will help to give a more detailed picture of food chains and energy flows inside the Wadden Sea.

由于北海和瓦登海的温度格局发生变化，2007年在叙尔特-勒姆岛湾（Sylt Rømø bight，SRB）启动了一项至少为期十年的鱼类调查。其目标是调查瓦登海的鱼类区系，重点关注洄游行为、物种组成和摄食习性的变化。SRB内部的7个站点每月采样一次；另外2个站点（一个位于海湾外，一个靠近丹麦边境）作为参考点，每年采样4次。采样使用小型底拖网（mini bottom trawl），总长17米，拖网开口宽7米、高3米；网翼网目尺寸为36毫米，中部为16毫米，囊网（cod end）为6毫米。每个站点分别在水体中和海底各拖网一次，每次持续15分钟，拖速约为2节。这些数据将有助于更详细地描绘瓦登海内的食物链和能量流动情况。
