Length-weight relationships and condition factor of Hyperopisus bebe (Lacepède, 1803) (Actinopterygii: Osteoglossiformes) in River Galma, Zaria, Kaduna State, Nigeria

Abstract
The investigation of length-weight relationship and condition factor are very relevant indices to ascertain the health of fish in the water body. Length-weigh relationship and condition factor of Hyperopisus bebe (Lacepède, 1803) (Actinopterygii: Osteoglossiformes: Mormyridae) in River Galma, Zaria, Kaduna State, Nigeria, were assessed. The mean length and mean weigh in male and female were 26.703 cm + 0.51 cm and 25.32 cm + 0.898 cm; 158.2 g + 10.1 g and 95.91 g + 9.26 g, respectively. The exponent or growth pattern 'b' values for male and female were 2.009 and 2.176. The condition factor for male and female were 0.59 and 0.83, respectively. The negative allometric growth pattern and poor condition factor might be due to the poor water quality in the fish ecosystem and should be regarded with concern.
