However, perfect agreement of ages between structures (i.e., scales and otoliths) did not occur. Crappie length at age should be back-calculated using otoliths when more precise age estimates are needed and with scales when fish are too few to be killed.

因此，對于逆推計算的研究欧美午夜激情网，沒有確定耳石和鱗片哪個是完美的在线欧美看片免费人成视频，但是在較少的樣本的前提下，用耳石來對灰刺蓋魚的體長與年齡比鱗片精確一些国产欧美国产综合每日更新。

To elucidate the relationship between otolith microstructure and microchemistry and the life history events of the grey mullet Mugil cephalus in the early stage, the daily growth increments, growth check, Sr/Ca ratios and trace elements in otoliths of the juvenile mullets collected from the four estuaries from NE to SW Taiwan coast from 1996 to 2004 were examined by using the light and electron microscopes, electron probe microanalyzer and laser-ablation inductively coupled plasma mass spectrometry. A transition check was found in otoliths of all mullets.
