Morphometrics, fecundity, density, and feeding intensity of the spinycheek crayfish, Orconectes limosus (Raf.) in natural conditions
The subject of the study was three populations of spinycheek crayfish, Orconectes limosus (Raf.) from Polish lakes: Staw Plociczno, Dgal Wielki, Hancza. The aspects of the spinycheek crayfish studied were the morphometric characters of females and males, individual absolute fecundity, sex ratio, siz...

| description | The subject of the study was three populations of spinycheek crayfish, Orconectes limosus (Raf.) from Polish lakes: Staw Plociczno, Dgal Wielki, Hancza. The aspects of the spinycheek crayfish studied were the morphometric characters of females and males, individual absolute fecundity, sex ratio, size structure, density, biomass, and feeding intensity in an annual cycle. It was determined that the body proportions of males in forms I and II differed significantly, while the body proportions of female spinycheek crayfish were similar to those of form II males but different from the body proportions of form I males. The crayfish investigated in the current study had a lower individual absolute fecundity than did spinycheek crayfish of the same body weights from other Polish basins. The crayfish daily food ration exhibited a very strong relationship with the stomach fullness index and water temperature. The crayfish fed most intensely from the May to October period. The primary dietary component of the spinycheek crayfish was plant matter |
