Résumé du livre
This study investigates some of the biological characteristics of alewife from Lakes Ontario and Huron. The genetic structure among Great Lakes alewife and additional alewife collected from the Maritime provinces was determined by comparing allelic frequencies of 25 protein-coding loci which were quantified using electrophoretic techniques. For Great Lakes alewife, several morphological characteristics (measurements of body parts) and meristic parameters (counts of hard bony structures such as fin rays) were also determined. Additional alewife were collected from the cooling water intake of Pickering NGS and the other adjacent open lake to evaluate their pathological and parasitological condition.
