Attempting to contribute with the knowledge about the bioecological aspects concerning the youth forms of M. furnieri (Desmarest, 1823) and C. leiarchus (Cuvier, 1830) from Itacorubi mangrove, 15 samplings were taken from January 1988 to March 1989. Using casting and entangle nets, a total of 308 individuais from these species were captured. Their abundanee were: M. furnieri N = 197 (64,0%); C. leiarchus N = 111 (36,0%). The relative frequency and range of total weights and lengths were studied. Concerning spatial distribution of the species, it was observed that M. furnieri occurred in all areas and C. leiarchus was not captured only in "D" area (Sertão River). During the anual cycle the two species occurred jointly. The results emphasize other authors statements that consider this mangrove as a "natural growing enviroment" which is highly important for the region.
