Productivity and technical efficiency of aquaculture production in Nigeria: A stochastic frontier production function approach

摘要

The Nigerian aquaculture industry ranks second in Africa and is fairly well developed. Yet it has low production levels when compared with the country's aquaculture production potentials in terms of available natural, environmental and socio-economic factors, which favor increased aquaculture performance. Nigeria has a potential land area of about 600,000 km super(2) and 400,000 km super(2) for subsistence and commercial aquaculture (Fagbenro et al. 2004). Aquaculture production in Nigeria occurs mainly inland and only recently has the coastal region been the focus of development. The country has a coastline of about 960 km bordering a coastal zone having an extensive mangrove ecosystem comprised of lagoons, estuaries, wetlands and a series of interconnecting creeks.
