Fish morphometric and physiology data. All data presented as mean ± standard error; HSI = hepatic somatic index, calculated as liver weight/fish wet weight; condition factor (K) calculated as (fish wet weight/(fork length³)); Haematocrit calculated after centrifugation of the blood in capillary tubes (see Section 2) and defined as a ratio of red blood cell (RBC) volume to total blood volume, and expressed as a percentage of total blood volume. LOQ = limit of quantification (20 μg/L).
