  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: Aquaculture in Urban and Peri-urban Areas: Implication for Food Security and Environment Consideration Author: Siyanbola, Omitoyin, Adebayo, Jumoke Change in climate, harvest stagnation in wild fisheries and overexploitation of popular fish species, combined with a growing demand for high quality protein and a need to sustain livelihood and improve food security has compelled aquaculturists to domesticate more fish species in environments which is not rural as the case used to be. The dwindling resources from the artisanal sector which provide employment for about 5.8% of the populaces and also supply more than 81.9% of the total domestic fish production is augmented by aquaculture which is the fastest growing production system in the world. Rural-Urban migration which is rapidly increasing has increased the pressure on the urban facilities. Expanding cities affect the areas surrounding the city by altering the natural resource base, converting land to new uses, changing labour patterns, challenging the environment, concentrating urban waste pollution and diminishing natural resource based livelihoods. The paper therefore looks at aquaculture in the urban and peri- urban for food security and its environmental implication. A random sampling technique was used to select 150 respondents from urban and peri- urban communities in Lagos state using structured questionnaire. Data collected include socioeconomic characteristics, production, sales and climatic data The effect of change in climate with a high percentage of people moving from the rural areas to the urban cities increasing congestion, unemployment, urban poverty and subsequently increasing food insecurity should be looked into. There is therefore the need for the Government to look into land use planning and land allocation to cope with rapid development and expansion.

  Citation × Citation Citation Abstract Copy Title: Economic Analysis of Fish Farming in Osun State, South-Western Nigeria Author: Olasunkanmi, John Bunmi Information on economic viability of aquaculture is crucial for investors when assessing the feasibility of an aquaculture investment. Unfortunately, such information has been scarce in Nigeria. The economic analysis of fish farming in Osun State, South-Western Nigeria was therefore carried out using data collected from seventy two randomly selected fish farms. Data were analyzed using descriptive statistics, costs and returns, as well as multiple regression analysis. The relationship between fish output and five inputs: feed, fertilizer, lime, labour and fingerlings were measured using Cobb-Douglass production model. Results suggest that a unit increase in fertilizer application contributed 46 percent increase to the profitability of the fish farms and this was significant at p<0.01. Also, labour was significant at p<0.05 as the results suggest that a unit increase in labour contributed 60 per cent increase to the profitability of the fish farms. The model explained 81% of the variation in total output. On the whole, fish farming was found to be profitable with a benefit-cost ratio of 1.65 and profit–cost ratio of 0.65. It is recommended that fish farmers in the study area should increase their use of feed, lime and fingerlings and decrease their use of fertilizer and labour. Data on the socio-economic characteristics of farmers revealed that most fish farmers (58.3%) in the State were males, aged between 31-50 years old. About 91.7% of fish farmers were married and 95.8% had formal education. About 86.1% owned land either by inheritance or purchase, 8.3% operated on leased land and 5.6% rented the land upon which they operated. About 75% of the respondents got their capital from personal savings, 11.1% from cooperatives, and only 5.6% had access to bank loans. About 52.8% were regularly visited by extension agents 16.7% were occasionally Title: Economic Analysis of Fish Farming in Osun State, South-Western Nigeria Author: Olasunkanmi, John Bunmi Information on economic viability of aquaculture is crucial for investors when assessing the feasibility of an aquaculture investment.

  Citation × Citation Citation Abstract Copy Title: Implications of Japanese Experience in Fisheries to Asia and the World Author: Matsuda, Yoshiaki Fisheries are increasingly important in the world with growing demand for fish in China, Western, African and Asian countries. Many people depend on fisheries and will be benefited from fisheries. Many governments took fisheries promotion policies after the 1970s when the UN 3rd Law of the Sea Conference developed. However, these resulted in over-capitalization, over-fishing, illegal fishing and resource depletion. Together with land-based environmental destruction and anti-whaling movement, capture fisheries situation is not optimistic. Aquaculture have been paid much attention along with poor prospects on capture fisheries. However, aquaculture is not problem free. Most of fisheries problems in the world are repetition of Japanese experience in fisheries now facing a big ban. This paper focuses on lessons learned from Japanese experiences to develop sustainable fisheries in Asia and the world.
