Pop-up Satellite Archival Tag (PSAT) 체외 부착방법에 따른 방어(Seriola quinqueradiata)의 혈액성상 및 PSAT 부착효율

Abstract

This study aimed to determine the effect of the pop-up satellite archival tag (PSAT) tagging method on the blood indices and PSAT attachment efficiency of yellowtail Seriola quinqueradiata (mean body weight 10.2 kg). Based on tagging method, the fishes were divided in four different groups: untagged (control), single anchor (SA), dual anchor (DA), and silicon tube (ST). The blood indices and PSAT attachment efficiency were investigated on days 1, 14, and 28 after tagging PSAT on the muscle below the dorsal fin for each tagging method in triplicates. After 28 days of tagging with PSAT, a significant increase was observed in plasma glucose level in the ST group and in total protein level in the DA and ST groups. The levels of glucose, total protein, and total cholesterol in the SA group after 28 days of tagging were significantly lower than in the control group. The efficiencies of PSAT attachment were 0% in the SA and DA groups on 14 days post-tagging, and 66.7% in the ST group on 28 days post-tagging. The study results indicate that the proper PSAT tagging method is the ST type. The information obtained in this study presents valuable data that provide the required PSAT operational tool for industrial development and ecological monitoring of yellowtail.
