ABSTRACT

A total of 1257 caprellids, mostly females, were collected, from Februaty to September 1991. The average sex-ratio was of 0,83, with a range from 1,58 and 0,20. Salinity ranged from 30‰ to 36‰ seawater and air temperature ranged from 26,00 to 17,66ºC and 25,23 to 18,60ºC respectively. Caprellid densities were higher during the cold months and males were the largest of the population. Males could be distributed in 12 length classes, while females in seven only.

Key words: Amphipoda, Caprella penantis, Anhatomirim, biology data
