We got 193 Megalobrama Skolkovii from the Nanshui reservoir to study fecundity,measured their body length and weight etc, justified the ages and the total spawn so as to get absolute fecundity and relative fecundity.

Embryonic development time and absolute fecundity of dolly varden charr ( S.

The result showed the enhancement of the absolute fecundity(F) of Protoslenx hyalocranius was with the depending of its body length and weight increased: as the body length increased 1 mm the spawns increased 636 particles and as the body weight increased 1 g the spawns increased 1068 particles.

The results showed that:the individual absolute fecundity of silver pomfret was 90 071.

The results are summarized as follows: The individual absolute fecundity of Coilia mystus is between 2816 and 22813 eggs and the individual relative fecundity r/L and r/W is 27~122 eggs/mm and 516 ~1002 eggs/g respectively; r and r/L increase according to the increase of fish body length,body weight and age,but the individual relative fecundity r/W is more stead.

Its constitution and function pattern may cause a series of practical problems such as "daughter households"problem, not only because of inherent social traditions, but also because of its intrinsic legal characteristic——the absolutness of regional effectiveness of rural autonomous power.
