Epidermal characteristics of reproductive subsets in an inshore population of winter flounder, Pseudopleuronectes americanus
The winter flounder, Pseudopleuronectes americanus (Walbaum), population off Newfoundland can include a ‘non‐reproductive post‐mature’ subset at any time together with ‘reproductive’ and ‘immature’ subsets. Skin samples were taken from male and female specimens from each subset in the winter, after...
