Abstract
Domestic fish production in Nigeria has been growing for the past decade, yet a widening demand-supply gap has persisted leading to a substantial loss in Nigeria’s foreign exchange earnings due to fish imports. In order to boost household food fish supply many individuals have converted available land space within their homestead for catfish production. This study, therefore, investigated the effects of socio-economic variables on the participation in homestead catfish production in the Central Agricultural Zone of Delta State, Nigeria. Using data from 137 respondents engaged in catfish farming, the findings showed a mean age of 44 years for catfish farmers and an average land size of 104.35 m2 for pond construction. The probit model had a good fit with a Psuedo-R2 of 0.62, 90.5 % of cases correctly predicted, and a significant likelihood ratio (LR) test (p < 0.01). Results of the probit analysis indicated that pond location, age, land area, adults per household, years of education, disposable income, and access to credit exerted a positive and significant effect on homestead catfish production participation decision.
Highlights
The global fish supply from capture fisheries and aquaculture was put at 158 million tonnes in 2012, with 136.2 million tonnes used for human consumption and providing an estimated apparent food fish per capita supply of about 19.2 kg
3.2 PROBIT MODEL RESULTS OF DETERMINANTS OF PARTICIPATION IN HOMESTEAD CATFISH PRODUCTION
The findings of the study are in consonance with that of Tenge et al (2004), who reported that elderly people are more keen to participate in new technologies because they have had more years of farming experience and more personal capital (Nkamleu and Manyong, 2005), so that they can invest in new innovations
Summary
The global fish supply from capture fisheries and aquaculture was put at 158 million tonnes in 2012, with 136.2 million tonnes used for human consumption and providing an estimated apparent food fish per capita supply of about 19.2 kg (live weight equivalent). The contribution of aquaculture to world fish supply reached an all-time level of 66.6 million tonnes in 2012 representing 42.2 % of global fish production, while the values were 1,485,367 and 454,691 tonnes, respectively, for Africa and sub-Saharan Africa (FAO, 2014b). Aquaculture has continued to remain a growing, vibrant and important production sector for high protein food supply for hu-.
