  Citation × Citation Citation Abstract Copy Title: Determinants of Land Leasing Decisions for Shrimp Farming: A Case Study of Smallholders' Shrimp Farming In India Author: Bhattacharya, Poulomi Using primary data collected from 208 shrimp farming households and 69 households leasing-out land for shrimp farming, this paper explores the demographic and economic factors influencing the land leasing decisions for traditional and scientific shrimp farming in West Bengal, India, applying Tobit Model. The results indicate that size of households‟ land holding is positively related with the extent of land leased-in for traditional shrimp farming whereas for scientific shrimp farming the association was found to be negative. This signifies that land leasing market does not facilitate the households having lesser landholding to lease-in land for shrimp culture in the case of traditional shrimp farming whereas in the case of scientific shrimp farming it does facilitate such households. In the case of traditional shrimp farming households‟ association with other fisheries related activities was also found to have positive influence on their leasing-in decisions . On the supply side, variables like number of adult male members, households‟ association with fisheries related activities and non-farm assets were found to have positive, negative and positive association respectively with the extent of land leased-out for traditional shrimp farming. The analysis also exhibits that the age of the household head has negative relationship with the extent of land leased-out by them both in the case of traditional and scientific shrimp farming. This signifies that existing institutional arrangements in shrimp farming of West Bengal are not considerably successful to motivate young rural people to undertake shrimp farming on their own instead of leasing-out land for shrimp culture and aquaculture policies should address this aspect.

  Citation × Citation Citation Abstract Copy Title: Farm-Level Efficiency and Resource-Productivity: Application of Stochastic Frontier Analysis to Aquaculture Farms in the South-West Nigeria Author: Ogundari, Kolawole This paper comparatively examined resource-use and technical (TE) efficiencies of aquaculture farms in the Southwest Nigeria. A total of 160 farms were randomly selected from four states across the region. Econometric applications of the stochastic frontier models provide measure of the farm’s technical efficiency. The results of regressions specified for the farms in each states, show that, elasticites for inputs, such as: size of the pond, feeds, labour, numbers of fingerling stocked, and costs of materials were positive and significant. This suggests that, the production functions monotonically increased with input from the study. The returns to scale estimates show that, an average farm in the states like, Ogun and Ondo exhibit increasing returns to scale, while similar numbers of farms in Osun and Ekiti states exhibit decreasing returns to scale. The results of marginal value product (MVP) show that, none of the farms across the states optimally used their variable inputs (MVPx =MFCx). Most farms were found to have underused (MVPx >MFCx) feeds and numbers of fingerlings stocked, as against overused (MVPx <MFCx) of labour across the states. The estimated TE shows that, about 11%, 18%, 22% and 44% of outputs of the farms in Ogun, Ondo, Ekiti and Osun states are forgone due to inefficiency respectively. The implications of these findings, therefore, suggest that improvement in the technical efficiency of the farms, as well as, optimal input utilization, will contribute significantly to aquaculture expansion program in the county.

• 7. [Article] Optimal Farm Size for the Production of the Mediterranean Mussel (Mytilus Galloprovincialis) in Greece

  Citation × Citation Citation Abstract Copy Title: Optimal Farm Size for the Production of the Mediterranean Mussel (Mytilus Galloprovincialis) in Greece Author: Adams, Charles M., Tzovenis, Ioannis, Sorgeloos, Patrick, Viaene, Jacques, Theodorou, John A. The profitability of the Mediterranean mussel (Mytilus galloprovincialis) farming depends on a combination of factors including natural productivity, technical practices, production costs and product pricing. In an effort to analyse the financial risks of the mussel farming in Greece, we examined the profitability of the different farm sizes (1 to 4 ha) under the present situation of the local market and the modern production practices. Assuming that a farm works at a reasonable 80 % of its annual capacity and uses the widely accepted long-line technique, it was demonstrated that a farm size less than 2 ha is not viable economically. Moreover, the cost of the new establishments and the modernization of the existing ones is affordable only if larger enterprise structures are adopted. Consequently, the past EU and/or public support (up to 45% of the total cost of the fixed assets) has been critical for the development of the industry. Taking in account that the majority of the Greek mussel farms are rather small (1-2 ha), we concluded that for financial sustainability the sector needs to be restructured and be organised in larger schemes, such as those of producers organisations or co-operatives, in order to benefit from scale economics and attract better funding.

  Citation × Citation Citation Abstract Copy Title: Role of Shrimp Farming in Generating Employment and income: A Study of Small- Scale Shrimp Farming in West Bengal, India Author: Bhattacharya, Poulomi In the light of the usual allegation against shrimp farming as an employment displacing activity, this paper tries to examine the role of shrimp farming in generation of employment and income for small scale shrimp farmers in West Bengal, India using primary data collected from 208 traditional and scientific shrimp farmers in West Bengal. The analysis reveals that the labour used (including family labour) for traditional and scientific shrimp farming were 101 mandays per acre and 300 mandays per acre respectively. Both the figures were more than the labour requirement for paddy cultivation in West Bengal. The finding refutes the allegation against shrimp farming as an employment displacing activity as compared paddy cultivation. A comparison of the household income of sample shrimp farmers with the rural poverty line in West Bengal revealed that shrimp farmers of all the categories (small, medium and large) were above the poverty line. However, per capita annual household income of marginal traditional shrimp farmers was quite close to the poverty line which emphasizes the need for pondering special extension facilities to these shrimp farmers. The study also shows that on the whole shrimp farming accounted for about 70% of the annual household income of the sample households. However the importance of shrimp farming was lesser in the case of shrimp farmers with lesser shrimp farm size. This indicates the quest of marginal and small shrimp farmers to diversify their source of income in order to cover the risk associated with shrimp culture. On the whole shrimp farming was proved to be an employment generating activity and had contributed significantly to the income of the sample households.
