CHAPTER ONE

1.0 INTRODUCTION

In Nigeria, fish alone contributes on the average 20 – 25% per caput animal intake and could be as high as 80% in coastal and reverine communities (Food and Agriculture Organisation, 2000). Tobor (1992) and Ajana (2002) reported that the average annual demand for fish in Nigeria between 1995 and 2000 was estimated at 1.22 million metric tonnes and that this might increase to about 1.425MMT by the year 2005. FAO (2000) estimated the projected population and fish demand/supply from 1997 to 2025, with domestic fish production by the year 2007 as 0.77 million tonnes. Adamu (2007) however, gave the actual total domestic fish production in 2005 as 579,500 tonnes, while production from aquaculture was 56,300 tonnes in the same year. Fasasi (2003) put the demand – supply gap of fish in Nigeria as 1.0 million metric tonnes.

Aquaculture, the rearing of aquatic organisms, has high prospects in Nigeria. With a projected population of 139.1 million people in 2007, the fish demand is estimated at 1.06 metric tonnes, while supply stands at 0.81 metric tonnes leaving a deficit of 0.25 metric tonnes (FAO, 2000). Faturoti (1999) noted that recent trends all over the world point to a decline in landing from capture fisheries which is an indicator that fish stocks have approached or even exceeded the point of Maximum Sustainable Yield (MSY). Aquaculture therefore remains the only viable alternative for increasing fish production in order to meet the protein need of our people.
