In addition, the abundance of part of trace element in the otoliths possibly has the good relevance with the responding elements in water. Through the analysis of micro-chemistry characteristics of the wild carp otoliths, the waters environment condition that wild carps live in should be possible reflected.

此外网站大全色网站，耳石中部分微量元素的豐度與各自水體的特征可能存在較好的相關(guān)性国产操逼免费看，利用野生鯉魚(yú)耳石的微化學(xué)特征應(yīng)該可以反映其所生活水域的環(huán)境狀況。

The result showed that, the carp otoliths of Heilongjiang Lianhuan Lake and Beijing city Miyun Reservoir has the ball aragonite and the column aragonite two kind of crystal types. The characteristics has relation to the average temperature and the difference in temperature of the water.

These two elements precipitate into otoliths crystal lattice or interstitial to substitute for calcium (Ca2+) in vaterite or aragonite. The precipitation of otoliths is controlled not only by biological regulatory, but also influenced by environmental factors, such as: element concentration, salinity, temperature of ambient water, food intake, etc.
