Abstract
The present study was carried out to determine the proximate composition and haematology of Nile Tilapia (Oreochromis niloticus) captured from the wild and those reared on a farm. The haematological parameters for farmed Nile tilapia had a higher level of erythrocytes 6.98 ± 8.28, haemoglobin 10.52 ± 3.09, haematocrit 31.85 ± 20.22 than those of the wild Nile tilapia. The result of the proximate composition showed farmed tilapia having values of protein, fat, carbohydrate and energy higher than the wild stock. However, the wild tilapia had higher values of moisture, ash and crude fibre greater than the farmed tilapia. This suggested that farmed Nile tilapia is better in terms of nutrition and health than the wild Nile tilapia from Lagos Lagoon. The stress posed by anthropogenic activities on the biodiversity of a tropical lagoon as the Lagos Lagoon is further revealed.
