This paper is an essential investigation into socio-economic determinants of utilization of Nigerian Stored Products Research Institute (NSPRI) fish smoking kiln across ten (10) Local Government Areas (LGAs) of Osun State, Nigeria. Using a semi-structured questionnaire as research instrument, data for the study were purposively collected from one hundred and eighteen (118) fish processors who use the NSPRI smoking kiln in the state. Multiple regression analysis show that a correlation (R=0.362) exist between utilization of the screw press and the independent variables which include age, household size, level of education, years of processing experience, extension visits, and membership of social organization. R2 value of 0.131 indicates that about 13% of the variation in utilization was explained by socio-economic variables included in the regression model. Two variables significantly influenced the decision of the respondents to utilize the NSPRI smoking kiln: household size and level of experience. Furthermore, adoption rate for the fish smoking kiln over a two-year period was 84.2%, and users of the kiln also moved from 118 to 747 within this period; an increase of 527%. The F-value of 2.782 confirms that there is significant relationship between the socio-economic characteristics of respondents and utilization of the NSPRI fish smoking kiln. Conclusively, the fact that independent variables included for this study were only able to explain 13% variation in utilization calls for mobilization of other variables not included in this study in further studies.
