Oocyte size and weight in Atlantic wolffish (Anarhichas lupus) and spotted wolffish (Anarhichas minor) were studied after fixation and storage in formalin. The effect of formalin on oocyte size varied depending on the original size of the oocyte. A formula was developed to convert fixed oocyte size/weight to fresh oocyte size/weight. The relationships were found to be negative and nonlinear, with smaller oocytes increasing in size and weight after fixation, while larger oocytes decreased.
Oocytes were sampled from Atlantic wolffish (Anarhichas lupus) and spotted wolffish (Anarhichas minor) to investigate the effect of fixation and storage in formalin on oocyte size and weight over time. The effect of formalin on oocyte size was dependent on the original size of the oocyte. As the effect of fixation was similar for the two species, a common formula for the conversion of fixed oocyte size/weight to fresh oocyte size/weight was developed. The relationships were negative and nonlinear, the smallest oocytes increased-11 % in diameter and-15 % in weight when fixed in formalin, whereas the largest oocytes decreased about 4 % in diameter and 7 % in weight. After fixation, oocyte diameter was stable for up to 2, but not 10 years and for up to 10 years for oocytes at CA and VIT stage, respectively.
