Socio-economic dimension of fish farming in Assam

Information on socio-economic framework of the fish farmer community forms a benchmark for policy formulation to develop this economically backward sector. Very few studies have been conducted on the socio-economic aspect of fish farming. Two districts of Assam, Darrang and Nagaon, were selected for this study where 120 respondents from each district were selected randomly. The characteristics representing the personnel and socio-economic attributes of the fish farmers are presented in this paper. The socio-economic status of fish farmers has to be improved by bringing the modern concepts of fish farming to the doorstep of farmers.

Social and economic implications of the fishery distribution patterns on Lake Victoria, Uganda

The fisheries of Lake Victoria have undergonea dramatic transformation during the last two decades. From being a locally based fishery with little intervention and capital investment from outside,the present fishery is dominated by national and international capital penetrating the industry. It is explosion in the growth of nile perch and the strong demand devloped for this fishin the global markets, which have transformed the fisheries of the Lake victoria. This report presents the results of a survey carried out between October 2001 and February 2002 about the fishery distribution patterns and their impacts on fisher communities of Lake Victoria. The fisheries distribution pattern of the lake is described as well as the flows and benefits from the fisheries resource and the resource constraints and sustainability options. A major part of the paper discusses some of the socio-economic impacts of the rapid changes that are responsible for the present fisheries. It particularly focuses on the effect of the Nile perch boom, its globalization and the development of the fish industry in Uganda, on food security and employment for the local population.

Economic value of the milkfish industry

A brief description is given of the milkfish (Chanos chanos) farming industry in the Philippines. Over the past 20 years, the relative importance of milkfish has declined with the expansion of tilapia, tiger shrimp and seaweed farming. In 1975, some 141,461 mt of milkfish made up 10% of the total fish production, whereas in 1995, the total milkfish harvest of 150,858 mt made up only 5.5% of the total fish production. Milkfish are harvested and marketed mostly fresh or chilled, whole or deboned, but some are canned or smoked. The domestic markets, mainly in Metro Manila, absorb most of the production. Milkfish is also absorbed in different product forms: dried, canned, smoked, or marinated. An export market for quick-frozen deboned milkfish fillets has begun to develop and fish processing companies are responding fast. The milkfish farming industry has important linkages with the various sectors that supply the inputs, and those that transport, store, market or process the harvest. For intensive milkfish farming to be both profitable and sustainable, more value-added products must be developed and marketed.

Socio-economic aspects of the fisheries of Nabugabo lakes and implications for management

Fisheries are very important to Uganda's economy. The sector provides a vital source of food, recreation, trade and socioeconomic well being for the people and community globally. The fisheries of small lakes are important for producing fish for local populations who are not near the large lakes. These satellite lakes support important fisheries and other economic activities like fishing, water for domestic purposes and tourism, besides socio-cultural values. A number-of fish;- species, some of which were found only in Lake Victoria have been depleted through over-exploitation, introduction of exotics especiaily Nile perch and environmental degradation. Some of these fishes have been observed to survive in satellite lakes in the Victoria and Kyoga Lake basins. The Nabugabo satellite lakes (Manywa, Kayugi and Kayanja) contain endemic Cichlid fish species acting as reservoirs and therefore very important for conservation of fish biodiversity. Despite the socio-economic importance and uniqueness of these satellite lakes little research on socio-economic studies has been carried out. The sustainability of the lake is being threatened by increasing human activities. The fish stocks and species diversity are declining and this poses a threat to the livelihood of the people who depend on fish for food and income. Arising from this need a study was carried out to establish the socio-economic aspects of Nabugabo fisheries and implications for management, on which basis resource users would be made aware of the impacts of their activities. It was hoped that this would go further to ensure wise use and management of the resources by the users. The specific objectives were identifying activities around the lake, establishing socioeconomic values attached to the lake, identifying problems of the lake and resource users and examining existing local based management institutions. Results show that the activities taking place around the lakes include fishing, farming, watering of animals, deforestation and charcoal burning, brick making, resort beach development and food and refreshment. The major problem facing the lake was found to be encroachment of Hippo grass (Vossia) on the lake, which is decreasing the size of the lake, and limiting open waters for fishing (this only applied to Lake Nabugabo). Other important problems include use of illegal fishing methods, declining fish stocks and loss of cultural identity. The resource users are most pressed by the low incomes resulting from poor fish catches, theft of gears and lack of market. On examining the resource base for the lakes, it was only Lake Nabugabo that had a Landing Management Committee. The other three lakes did not have leadership institutions in place except the local councils for the respective villages. This was probably due to observed limited fisheries activities. Majority of the respondents agreed that Government and other service providers should work jointly to supplement local beach management committees in the management of the lakes resources. This is a good gesture because with increase in fishing effort and rampant use of illegal fishing methods, there is need to strengthen management institutions present on the lake. This would require Government, local community and other service providers to work together in a participatory way to control environment-degrading activities and stop the use of illegal fishing methods. Burning of vegetation on the lake should be stopped since it enhances growth of this grass. Finally, traditional taboos; which are present on some of the Nabugabo lakes, should be enhanced, as away of preserving them.

The socio-economic aspects of the fishing communities of Lake Victoria, Uganda

A baseline survey of the fishing communities was conducted in 2005/06 as one of the main studies under the Socio-economic Research and Monitoring Working Group on Lake Victoria. The overall objective of the survey was to provide a deeper understanding of the broad socio-economic characteristics and well being of the different stakeholder groups immediately dependent on the Lake Victoria fisheries. An understanding of socioeconomic status of the fishery primary stakeholders, who include fishers, artisanal processors and traders, is essential for any subsequent periodic evaluation of development. During the survey, a total of 1,235 respondents were interviewed, at 34 landing sites in all the Ugandan districts on Lake Victoria. The purpose of this fact sheet is to provide information on the fish landing beaches, people involved in fisheries, their livelihood activities and facilities available to them.

The temperature dependence of the development of the embryo in Mesocyclops leuckarti (Claus) and Cyclops scutifer

This work is mainly intended as an addition to the studies of the populations dynamics of Cyclops scutifer, which is part of the ”Latn ja jaure project” (a study of the principles involved in the ecosystem of a small -initially fish free- mountain lake, before and after the introduction of fish). The field work consisted of sampling in Lake Erken in Roslagen in June, July and September, as well as in Latn ja jaure in the Abisko mountains in August and September of 1965. Additional sampling was done in Latn ja jaure for the study of the horizontal, vertical and temporal distribution of Cyclops scutifer, as well as the in situ development of the different stages. These samples have been analysed in such a way as to fit into the frame work of future studies on the population dynamics of Cyclops scutifer, The main aim of the present investigation is the determination of the dependence upon tempera- tare of the development of the embryo in the subarctic Cyclops scutifer as compared with the conditions found in the warm water species Mesocyclops leuckarti.
