“…About 23% of the artisanal gill net fishery landings in the Nigerian inshore waters east of the Niger come from bonga (Moses, 1988). Ama-Abasi and Holzloehner (2002) have demonstrated that the Cross River Estuary is a nursery area for the species where the juveniles are found from November of each year to May or early June of the following year. Two main fisheries exploit the resources in the Cross River Estuary, namely: the artisanal gill net fishery and the semi-industrial purse seine fishery.…”

“…Cross River Estuary takes its rise from Cameroon Mountains and flows west ward into Nigeria, then Southward into Atlantic Ocean at the gulf of Guinea. It occupies an area of 54,000km 2 with 39000km of the area in Nigeria (Ama-Abasi andHolzlobner, 2002 andAkpan andOfem, 1993). The Estuary is located approximately between latitude 4° and 3 o N and Longitude 7° 30 and 10°E in the South East of Nigeria.…”

Four Hundred (400) samples of Chrysichthys nigrodigitatus were examined for Henneguya chrysichthys using methods described for gills examination and haemopatholgy. 135 (33.8%), Chrysichthys nigrodigitatus were infected by Henneguya chrysichthys. The infection was seen on the gill filament as an oval cyst somewhat white and visible to the naked eyes. 27 (20%), 88 (65.2%) and 20 (14.8%) were recorded for low, moderate and high infection respectively. Lowest (22.7%) and highest (45.5%) prevalence were observed in the months of December and May respectively. Prevalence was higher in wet season (54.1%) than in dry season (45.9,%) More female fish (51.1%) had infection than the male fish (48.8%).Haematological examination revealed changes in blood cell count, erythrocyte sedimentary rate and Haematocrit counts. Hemoglobin (per 100mI) remains the same in infected and uninfected fish. Erythrccyte count (X10 6 /mm 3) was 1.28±1.11 and
