The study analyzed the socio-economic determinants of net-income in aquaculture of Kainji, Lake Basin, Nigeria. Specifically, the study examined the; fish farming systems; cost and returns, socio-economic determinants of net-farm income and challenges of fish farming in the area. The study adopted a two-stage sampling procedure to select 120 table-size fish farmers. Data were collected with questionnaires that were administered through face-to-face interview and analyzed using descriptive statistics, budgetary technique and multiple regression analysis. The results showed that 35.00 % of the fish farmers were within the age bracket of 31-40 years, 53.34 % were men, 91.67 % were married, 55.83 % had between 1-5 years of experience in fish farming and 75.83 % had tertiary educational qualification. Majority (92 %) of the fish farmers practiced the monoculture of catfish using earthen ponds system. The estimated total expenses were N 14,953,330.74 while the total revenue generated from 9 fish ponds, each stocked with an average of 3883.986 fingerlings in 2 cycles per year was N 20,188,142.00. The estimated net-farm income after tax was N 5,234,811.26 while the net profit margin and return on investment was 25.93 % and 35% respectively. Age, experience and household size were positive and significant (p<0.05) socio-economic factors that affected netfarm income while the challenges of fish farming were high cost of feed (x̅=3.24), poor pricing (x̅=3.11), poor access to capital (x̅=3.09) and persistent poaching/theft (x̅=2.67). Based on the findings of the study, it is recommended that there should be an intensive research by the fish nutrition division of National Institute for Freshwater Fisheries Research (NIFFR) on the possible alternatives of crude protein source that could be a perfect substitute to Clupeids in fish feeds.

Patent Medicine Vendors (PMVs) can play a critical role in increasing access to emergency contraceptive pills (ECPs) in developing countries, but few studies have examined their knowledge and dispensing practices. Using cluster sampling, the authors selected and interviewed 97 PMVs (60.8 per cent female) in Oyo and Ogun States of Nigeria to assess their knowledge, dispensing practices, and referral for ECPs. About one-third (27.8 per cent) of respondents were not aware of ECPs, and only half knew that ECPs could prevent pregnancy. Forty per cent had ever dispensed ECPs. Reasons proffered by those who do not dispense ECPs included barriers from the State Ministry of Health, police, other regulatory agencies, and religious beliefs. Only 50.5 per cent have referral arrangements for clients. Strategies to increase access to ECPs through PMVs include training on counseling techniques and referral, effective government regulation, and community involvement. Where unsafe abortion is a major cause of maternal mortality, these strategies offer protection for many women in the future. [ABSTRACT FROM AUTHOR]
