Morphological changes and allometric growth in hatchery-reared Chinese loach <Emphasis Type="Italic">Paramisgurnus dabryanus</Emphasis> (Dabry de Thiersant, 1872)

The length-weight relationship and allometric growth patterns of hatchery-reared Chinese loach, Paramisgurnus dabryanus (Dabry de Thiersant, 1872), were determined from hatching to 60 days after hatching. A best power model was estimated for the length-weight relationship during the early life stages. Positive allometric growth for the head segment, trunk length, tail length and eye diameter was also found in the early life stages, while body depth, tail depth, tail fin length, pectoral fin length and barbel length displayed a negative coefficient. During the subsequent early developmental stage, the growth coefficients showed a clear and common tendency towards isometry for all measured body ratios. The allometric growth changes in Chinese loach during the early stage are possibly the result of selective organogenesis directed towards survival priorities.     

长城，也可以这样拍

大伙儿们拍长城,总要表现的是长城的磅礴气势．苍凉风骨,深厚文化,好像不如此．即是不人流的长城片。我以为．其实长城真的就是一堵墙．一堵很长很长的墙。是阻挡敌兵入侵的一种屏障,而且还真的没挡住．外族军队还是跨过万里长城．长驱直入．
