  Citation × Citation Citation Abstract Copy Title: Measurement of Technical Efficiency of Farmed Catfish Production in Southwest, Nigeria: A Stochastic Frontier Production Function Approach Author: Mafimisebi, Taiwo Ejiola Catfishes are the most popularly raised and consumed fish species in Nigeria. Given changes in the dynamics of the aquaculture sector, this paper estimated technical efficiency and factors contributing to it using data collected from 108 farmers stocking catfish in earthen ponds in the study area. Catfish aquaculture was found to be capital intensive. The most expensive item of total variable cost (TVC) was fish feeds which accounted for 61.4% and 67.8% of TVC in Ondo and Ogun States, respectively. There were no significant differences in cost items between the two States. Empirical analysis showed wide variations in predicted TEs across farms ranging from 48.4% to 77.2% in Ondo State and 45.4% to 82.1% in Ogun State with means of 64.0% and 67.0%, respectively. The results also indicate that coefficients of the quantity of feeds, total number of ponds, labour and number of times pond water is changed were positive and highly significant in catfish production. The inefficiency model revealed that age and farming experience coefficients (significant) and education level coefficient (not significant) were negative indicating that older and more experienced farmers tended to be less inefficient. The test of various null hypotheses showed that the inefficiency effects were related to the age, management pattern, years of experience and education level of farmers. The study identified the opportunities that exist for improving TE in the study area. Results of the analysis having implications for the aquaculture industry and for policy-makers were discussed.

• 2. [Article] Comparative Analysis of Fresh and Dried Fish Consumption in Rural and Urban Households in Ondo State, Nigeria

  Citation × Citation Citation Abstract Copy Title: Comparative Analysis of Fresh and Dried Fish Consumption in Rural and Urban Households in Ondo State, Nigeria Author: Mafimisebi, Taiwo Ejiola A sine-qua-non for eradicating protein malnutrition in Nigeria is increased ingestion of high-value proteins found in various fish forms. This study attempted to give empirical backing or refutation to the assertion that dried fish is consumed more than fresh fish in Nigeria. Data used were gathered in 90 rural and urban households selected through multi-stage sampling technique. Analytical tools used included descriptive, Z-test and Chi-square statistics and regression model. Empirical results revealed mean household size of 7 in both households while average annual income was N471,200.04 ($2,908.6) and N326,466.58 ($2015.2) in urban and rural households, respectively. The average quantity of fresh and dried fish consumed per household per year was 13.0kg and 47.0kg in urban, and 11.5kg and 38.0kg in rural households, respectively. There was no significant difference in the consumption of the dried (1.779, p > 0.10,) and fresh (1.904, p > 0.10) fish forms in both households. OLS regression result revealed that household head’s age and numbers of children below 15 years were not significant in influencing consumption (p> 0.10). Contrariwise, household size and fish price significantly negatively influenced quantity of fish consumed while household income exhibited significant positive effect on consumption. The education variable, which was not significant in dried fish consumption, had significant positive influence on fresh fish consumption. However, 50.0% and 27.0% of the respondents rated affordability and accessibility as the main hindrances to consumption. Policy options directed at tackling the high cost of fresh fish to achieve reduced price and increased consumption, were recommended.
