Última NOTES ON THE BIOLOGY AND ECOLOGY OF Sudanonautes floweri (DE MAN, 1901; CRUSTACEA: BRACHYURA: POTAMOIDEA: POTAMONAUTIDAE) IN RIVER OGBOMWEN, SOUTHERN NIGERIA Acta biol.Colomb. ARIMORO,FRANCIS O; OROGUN,ENAKEME O. Investigation into some aspects of the biology and ecology of the freshwater crab, Sudanonautes floweri (De Man, 1901) in River Ogbomwen, Edo State, southern, Nigeria was carried out between February and July 2006. The study revealed that the crab species were widespread and abundant in the river. Abundance in terms of number and biomass was more during the wet season with at a peak in the months of June and July. The crab grew allometrically attaining a maximum total length and weight of 11.5 cm and 65 g respectively. The condition factor ranged from 8.60-9.45. These values did not vary with size and sex of the crab but showed seasonal variations. Females of Sudanonautes floweri were more abundant although not significantly different from the expected 1:1...

ARIMORO,FRANCIS O; MEYE,JACOB A. Preliminary investigation into some aspects of the biology of the palaemonid prawn, Macrobrachium dux (Lenz, 1910) in River Orogodo at Abavo, southern Nigeria was carried out between March and August 1995. The freshwater prawns were collected with properly baited cage traps and scooping with hand basket. The study revealed that the prawn species were widespread and abundant in the river. Abundance in terms of number and biomass was more during the wet season with a peak in August. Both adults and juveniles showed a progressive increase from late dry season to midrainy season (August). The malefemale ratio was 1:1.2. The fluctuation in the number and percentage of ovigerous females indicated that the prawn spawned during the midrainy season (JuneAugust)....
