Abstract
The study examined the technical efficiency of small scale shrimp fishers, the socio-economic characteristics and specific factors that affect the efficiency level, and the costs, revenues and profit structures of non motorized small scale shrimp fishers in the coastal areas of Delta State. The study was based on primary data obtained in a cross section survey that involved 220 shrimp fishers selected using a multistage random sampling procedure in four Local Government Areas of Delta State between July and October, 2010. Applying a Cobb Douglas stochastic production frontier function analysis to the data sets, the results showed that the mean technical efficiency (TE) was 73% for non motorized shrimp fishers in the study area. The result also showed that boat capacity, nets and labour impacted positively on output of shrimps with nets being significant at 5% while the technical efficiency of these fishers were positively and significantly related with age, education, access to credit, distance covered and membership of local cooperative groups. Results from the analysis showed that the average gross margin and net margin of non motorized small scale shrimp producer per year are N709, 636.67 and N619, 086.33 respectively while the return on sale was 0.37, return on investment was 265% and operating ratio was 0.39 indicating high profitability of shrimp fishing enterprise in the study area. In order to improve the technical efficiency, profitability and income of artisanal shrimp producers, Government needs to initiate and implement policies aimed at the provision of subsidized inputs (nets boats, and outboard engines), improve access to credit, encourage local cooperative group formation and regulate and enforce relevant laws to control water bodies pollution and environmental degradation.

Highlights
Shrimps are among the most important living resources in Nigeria’s estimated 853km coastline and 210,900km2 marine water including a 200 nautical miles Exclusive Economic Zone (EEZ) in which she has exclusive right to fish and other natural resources (Sogbesan et al, 2006; Chemonics, 2002; and CEHRD, 2007)
The study was conducted in the coastal areas of Delta State which consists of 8 local government areas (LGAs) namely: Bomadi, Burutu, Isoko North, Isoko South, Patani, Warri North, Warri South and Warri South West
This result showed that small scale non-motorized shrimp production is dominated by women and these findings are consistent with results of other studies by Verstralen and Isebor, 1997; and CEHRD, 2007
Summary
Shrimps are among the most important living resources in Nigeria’s estimated 853km coastline and 210,900km marine water including a 200 nautical miles Exclusive Economic Zone (EEZ) in which she has exclusive right to fish and other natural resources (Sogbesan et al, 2006; Chemonics, 2002; and CEHRD, 2007). The rural coastal communities in Delta State offer a great potential to alleviate poverty, generate employment and earn income on a sustainable basis. This potential can only be achieved if productivity and efficiency are increasing and this requires an understanding of the current efficiency or inefficiency inherent in artisanal shrimp production as well as factors responsible for this level of efficiency or inefficiency
