During each day of the study, we compared the biomarkers made from 20 salmon which were stocked for propagation to the eyed-egg ratio in hatcheries. Ovarian fluid pH, sperm motility time, and sperm motility rate were related to low eyed-egg ratio during the early period of artificial insemination. Our results suggest that the ovarian fluid pH, sperm motility time and sperm motility rate are meaningful biomarkers for the management of eyed eggs.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"人工授精の目的で蓄用したサケ親魚の群から精子運動時間，精子運動率および雌の体腔液の pH を測定した。9 月下旬から 10 月下旬まで 5
