Syngnathus rostellatus 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（Wadden Sea）的温度模式发生变化，叙尔特-勒姆岛湾（Sylt Rømø bight, SRB）于2007年启动了一项至少为期十年的鱼类调查。该调查旨在研究瓦登海鱼类区系，重点关注迁徙行为、物种组成及摄食习性的变化。SRB内部设有7个采样站，每月开展采样；另外增设两个参考站（一个位于湾外，一个靠近丹麦边境），每年采样四次。采样采用小型底拖网（mini bottom trawl），总长17米，网口宽7米、高3米，网翼网目尺寸为36毫米，中部为16毫米，囊网为6毫米。每个采样站均进行一次水柱拖网作业和一次底拖网作业，每次作业持续15分钟，速度约为2节。这些数据将有助于更详细地揭示瓦登海内的食物链与能量流动规律。
