Abstract:
Fat greenling, Hexagrammoso takii (average length of 5, 8 and 11 cm) were tagged with three kinds of T-bar tags (T1, T2, T3). The survival rate, tag-shedding rate, swimming and feeding behavior, growth performance of fat greenling juveniles post tagging were observed and recorded. Based on these data, we determined the suitable T-bar tag for fat greenling juveniles at different size. The results showed that fat greenling juveniles with total length less than 5 cm were not suitable for tagged releasing; the T1 tags were suitable for fat greenling juveniles with average length of 8 cm with tag-shedding rate of 4.83%, survival rate of 97.17%; the T1 and T2 tags were suitable for fat greenling juveniles with average length of 11 cm with tag-shedding rate of 2.00% and 5.67%, survival rate of 100% and 95.83%. In June 2017, the experiment of tagged releasing was carried out in Yantai offshore, using the fat greenling juveniles with T1 tags, and achieved good tagging results.
摘要:
以大泷六线鱼为研究对象,研究了3种不同规格的T型标志牌(T1、T2、T3)对平均全长5、8和11 cm鱼种的标志效果,记录了标志后鱼种的存活率、脱标率、行为特征及生长情况,筛选了适宜不同规格大泷六线鱼标志放流的T型标志牌。结果显示:平均全长5 cm及以下的鱼种不适宜标志放流;平均全长8 cm的鱼种适宜用T1标志牌,标志后脱标率为4.83%,存活率为97.17%;平均全长11 cm的鱼种适宜用T1和T2标志牌,标志后脱标率分别为2.00%和5.67%,存活率分别为100%和95.83%。2017年6月,在烟台近海开展了T1标志牌标志大泷六线鱼的放流试验,取得了良好的标志效果。
