Body measurements of Gadus morhua during Alkor cruise AL588@en

This data set includes single fish cod data collected during the RV ALKOR cruise AL588 conducted in March 2023 (1st to 10th of March) in the Western Baltic Sea by the University of Hamburg. The cruise was part of the 5-year MARSYS teaching cruise program of the University of Hamburg GFP20-1_047. All single fish measurements were made directly on board. Full wet weights of cod were measured and subsequently cod were gutted and liver weights, gonad weights and sexes, gutted wet weights (i.e., gutted wet mass), gonad stages and liver nematode infestations were recorded, and Otoliths were taken.本数据集包含2023年3月（3月1日至10日）在西波罗的海开展的RV ALKOR AL588号科考航次中采集的单尾鳕鱼数据，该数据由汉堡大学采集获取。本次航次属于汉堡大学为期五年的MARSYS教学科考项目GFP20-1_047的一部分。所有单尾鳕鱼的测量工作均直接在科考船上完成：首先测定鳕鱼的全湿重，随后对鳕鱼进行剖腹去内脏处理，依次记录其肝脏重量、性腺重量、性别、去内脏后湿重（即去内脏湿质量）、性腺发育分期以及肝脏线虫侵染情况，并采集耳石(Otoliths)。
