  Citation × Citation Citation Abstract Copy Title: Oyster farming and externalities: a bioeconomic approach Author: Le Rouxel, Astrid, Barillé, Laurent, Le Bihan, Véronique, Le Grel, Laurent The management of the French shellfish industry has been based for a century and a half on a Territorial Use Right in Fisheries (TURF) scheme. This was meant to ensure control over access and use and was seen as a potential remedy for overexploitation. But the resource, i.e. shellfish nutrients, is mobile and carried by streams. As a consequence, space allocation is far from being an efficient tool to share the resource between producers. The history of the French shellfish industry is marked by a series of overfishing crises occurring in most of the open-access shellfish beds located all along the French coastline. When the concession system was enforced (1852), it was designed to cope with congestion and overfishing issues more than with the development of shellfish culture. After turning into a breeding activity in the late nineteenth century, the oyster industry kept suffering major crises such as massive diseases. Their occurrence can be analysed in terms of overexploitation resulting from technological externalities. This article presents the current progress in the bioeconomic modelling of the oystergrowing industry in the Bay of Bourgneuf (Pays de la Loire). In this bay, 400 firms, mostly family-sized, are being conceded 1,000 ha and sell about 1,0000 tons of Crassostrea gigas oysters a year. The model will highlight the externalities that result from the concession system and provide a basis for discussing policy measures.

  Citation × Citation Citation Abstract Copy Title: Economic Potentials of Women in Small-scale Fisheries in West Africa Author: Williams, Stella B. Year: 2001 In the past three and a half a century since fisheries development was embarked upon in West Africa, the significant contributions of women in sustaining the socio-economic livelihoods of their families has been neglected and taken for granted. Development and support systems have paid much less attention to the economic potentials of women in small-scale fisheries in West Africa. Women in developing economies, especially in Africa lack access to services such as credit, fisheries extension, technology, information and basic education which are critical for shifting patterns of fisheries production or increasing output, all these are limited. Research information on the role and extent of women’s involvement in agricultural and/or fisheries development process show a genuine desire to improve their socio-economic status. However, by a combination of factors, women could not break through the cycle of poverty. There is therefore need for the support systems to be organized in a way that should bring about social changes that may be resisted at first, but will eventually promote the role of women in the economy. Gender relations should not be seen as competitive but rather as complementary and mutually reinforcing. General recommendations include: training and extension programmes in fisheries targeting women in areas where they contribute to fisheries activities like processing, packaging, distribution and marketing; microcredit programmes to benefit women; networks formed at national level with the active participation of all the stakeholders.

  Citation × Citation Citation Abstract Copy Title: Increasing Efficienty of Pond Fish Production in Rural Bangladesh Author: Chowdhury, Masudul Hoq, Maharjan, Keshav Lall Year: 2001 Fish is the main animal source of protein for the people of Bangladesh. As a principal source of protein, the per capita production of fish is declining. The present study highlights the development of pond fish production through grassroots level organization. The study was conducted in rural areas of Bangladesh. Eight villages were selected for this study of which four were from a rural development project area, the comprehensive Village Development Program (CVDP) and the rest were from non intervened area. It was revealed that level of education, size of land holding, family income etc. were important socio-economic factors affecting the utilization of pond fish farming. The findings of the study also indicated that, ownership pattern of pond, size of pond, location of ponds had a significant impact on pond fish production in the study area. The results of the study clearly indicated that the farmers of CVDP area had used more modern inputs like, manure, fertilizer, and feed and also better management practices than the non-CVDP area. The higher number of ponds (57%) in CVDP area was under intensive and semi-intensive cultivation, which gave them higher production (2653kg/ha/yr). On the other hand the majority of the ponds (72%) in non-CVDP area were under extensive cultivation (1100kg/ha/yr). Finally it might be concluded that, there was a sharp difference in the production practices of pond fish culture between CVDP and non-CVDP area. The grassroots level village organization had played a significant role in the process of technology transfer from the Thana level to the village level in the project area.

  Citation × Citation Citation Abstract Copy Title: Developing Smallholder Aquaculture in Kenya into Viable Enterprises: A case study of Nyaguta fish ponds in Kisii, Kenya Author: Charo-Karisa, Harrison, Okechi, John, Mikolasek, Olivier Smallholder fish farming contribute to improved nutrition, incomes and livelihoods of rural communities. Despite the potential, aquaculture in most rural areas is based on extensive production systems characterized by low availability in inputs. In Nyaguta, farmers are involved in agricultural production activities, including fish farming. However, most farmers do not keep records of resources used in their ponds (inputs, and labour) and outputs. This makes it impossible to assess the profitability of the enterprises. A study was carried out with the objectives: To characterize the inputs used by the farmers and determine the rearing parameters, to describe the fish farmers' practices and assess the fish farming cycle and to determine profitability. Monosex tilapia was stocked in 300m2 ponds at 3 fish/m2 and fed on pellet feed at 5% body weight. Semi-quantitative and qualitative data was collected from nine ponds over the production cycle (February 2010 to June 2011). An enterprise budget was used to compare profitability. Sale of harvested fish, gave the revenue or total income (TI) from each pond. Variable costs (inputs, labour and other operational inputs) were calculated. Family labour costs, were calculated separately to differentiate from casual labour. Total income (TI) less total variable costs (TVC) gave net income (NI) for each pond. From such a snapshot analysis of costs and returns, farmers would tell if their ventures were profitable or not. It also offered them an opportunity to determine areas to cut down or upscale during the production cycle to maximize on profits. It is only after profit realization, that farmers can be motivated to continue investing in fish farming and related activities.
