Abstract:The age and growth of Paramisgurnus dabryanus (385 individuals) and Misgurnus anguillicaudatu (177 individuals) sampled from Zhengzhou city,Henan Province were studied using scale and otolith in October,2012.The results showed that the scale and otolith were suitable for determinations of age structure and growth of these two kinds of loaches,which had 5 different age groups and most of them belong to the 1-3 year group.The relationships between body length and scale radius for P.dabryanus and M.anguillicaudatus were beeline correlative and the expressions were LP=4.4602r+5.3128 and LM=8.5110r+3.0081,respectively.The growth rates for body length and weight were similar of these two loaches,with the equations of WP=0.008L3.051(R2=0.886 0) and WM=0.009L2.992(R2=0.869 3),respectively.The body growth pattern could be well described by von Bertalanffy equation of LP=21.84\[1-e-0.129(t+3.638)\] and LM=28.02\[1- e-0.097(t+3.521)\],respectively.The rapid growth stage for P.dabryanus and M.anguillicaudatus was before the age of 2 and 3,respectively.In addition,the results showed that the minimum fishing specifications length for these two loaches was 13 cm.
