| The reproductive aspects of the freshwater shrimp Palaemon pandaliformis (Stimpson, 1871) were studied from March, 1998 to February, 1999. Monthly, samples were collected with sives, on the river edge, under the edging vegetation or in small pools. At the laboratory, shrimps were sexed and measured in their total lenght, from the tip of the rostrum to the of telson with precision callipters. The ovigerous shrimps were separated and counted for fecundity determination. The eggs diameter was measured with calibrated stereomicroscope. A total of 872 were collected among which, 46% female, 29% male and 25% juvenil. The sex ratio was 1:1.57. Ovigerous females were present during all seasons, but the reproductive peak accurred in Spring. The ovigerous female... |

| Biometric and reproductive aspects of Palaemon pandaliformis (Stimpson, 1871) from Ratones Mangrove, Florianópolis, Santa Catarina, have been investigated. Individuals were monthly collected from August, 91 to July, 93 and the temperature and salinity registered. Biometry, sex-ratio, sexual maturity, fecundity and reproductive cycle have been determined. The temperature showed defined temporal distribution. This species presents animal reproductive cycle, relatively high individual and populational fecundity, and the ovigerous females were larger than males and other females of the same species. |
