The life history pattern of Megalobrama pellegrini was studied by logistic regression model built according to 7 ecological characters of 34 freshwater and marine shore fishes in China.

The life history pattern of Gymnocypris przwalskii przewalskii(Kessler) was studied by fuzzy pattern recognition and tested by Beventon-Holt equilibrium yield model.

The results showed that the relationship between body length or body weight and age can be better described by the von bertalanff growth equation (VBGE) According to the typical characteristics of r and k selection and the given values of seven ecological parameters, it is concluded that the life history pattern of Snakehead fish (O argus) tends to r selectio

In this research we measured the population structure parameters(including body length,body weight and age structure)of Leucisus waleckii in Dali lake which is a salinc-alkalinc lake situated in Inner Mongolia,estimated the population parameters of growth and mortality,and studied the population life-history pattern.

Based on Thomas (1991, 1995) and Yu Dongming s (1997, 1999) studies on activity types, this paper attempts to analyze one typical conversational activity in psycho-logical counseling according to Chinese corpus.
