Morphometric Relationships and Relative Condition Factor of Auchenoglanis occidentalis (Cuvier and Valenciennes) from River Rima, North-Western Nigeria

Length-Weight Relationship and Condition Factor of Auchenoglanis occidentalis (VALENCIENNES, 1775) from Lake Akata, Benue State, Nigeria.

“…This is in agreement with previous studies on different fish species from various water bodies [34]; [35]. However, [36] reported allometric growth pattern for A. occidentalis in River Rima, North-western Nigeria and the "b" value is consistent with the "b" values reported for A. occidentalis in this study. [14]reported allometric growth pattern forB.…”

“…The condition factors of male and female sexes of A. occidentalis (K= 1.53, and 1.52 respectively) in Lake Akata is lower than values (2.26 and 2.27 respectively) reported for A. occidentalis in River Rima, North western Nigeria by [36]. There were no significant differences between the condition factors of male and female of A. occidentalis (p>0.05).…”

Reproductive biology of the orangefin ponyfish Photopectoralis bindus (Valenciennes, 1835) off Mangaluru coast, Karnataka

“…Males had lower gonadosomatic indices than females of corresponding gonad stage of development. This is in line with the assertion that gonado-somatic indices are generally higher in females than males on account of additional weight gain of ovaries in the breeding period as a result of accumulation of yolk in the eggs and also due to uptake of fluid by ripe oocytes (Shinkafi and Ipinjolu, 2012).…”

Some Aspects of the Biology ofDistichodus rostratus (GUNTHER, 1864) in River Rima, North-western Nigeria

“…Better condition factor in males than in females was also reported by Ikomi and Odum (1998) as in the case of samples of this study. Better condition in larger specimens than in smaller ones has also been reported by Ikomi and Sikoki (2003), Shinkafi and Ipinjolu (2010) and Shinkafi and Hassan (2011), and this may be due to better foraging ability and conservation of stored food energy in the adults, or possibly due to increasing weight of maturing gonads in the larger samples.…”
