Biometric measurements of fish in the Eastfrisian Wadden Sea during POLARIS cruise PO0199@en

Depth, water was calculated as mean from bathymetric depths at start/end of trawl. Standard length of Brachyra = width of carapax of Brachyra; Standard length of Natantia = length of rostrum to telsons of Natantia.水深（Depth）通过拖网作业起始与结束时刻的测深水深（bathymetric depths）平均值计算得出。短尾类（Brachyra）的标准体长等同于其头胸甲（carapax）的宽度；游泳亚目（Natantia）的标准体长为其从额剑（rostrum）至尾节（telson）的长度。
