  • Abstract:

The physico-chemical parameters and fish diversity of Agboyi creek using Shannon’s index and Simpson’s index were
determined for two years between 2005-2007 (both dry and wet seasons). Agboyi creek was characterized with high
BOD values of 25.56±3.10mg/l and 18.17±6.06 mg/l, nitrate (1.67±0.15 and 2.61±0.46 mg/l), phosphate (1.30±0.23
and 1.55±0.15 mg/l), ammonia (2.01±0.89 and 2.00±1.30 mg/l) and salinity (3.82 ± 1.59 and 3.75±1.03) during dry
and wet seasons respectively. Except for ammonia and salinity, there were no significant differences (P<0.05) between
the parameters, locations and seasons. Tilapia zillii, Sarotherodon aureus and niloticus were common to all the three
locations sampled (A, B, and C) and for both dry and wet seasons. Fishes such as Pomadasys jubelini and Caranx
senegalus were found only in location A; Sardinella maderensis, Trachinus apmatus and Arius gigas were restricted
to location B while Pellonula afezeliusi, Hydrocynus lineatus and Elops lacerta were recorded only in location C.
Fish diversity differs significantly with seasons (P<0.05) and significantly correlated with DO (r = 0.86). The
biodiversity indices showed low fish diversity in the creek throughout the sampling seasons.
