Seaweed farming based primarily on the culture of Kappaphycus and Eucheuma species has grown significantly in the Philippines and Indonesia over the last two decades, with growth also taking place at a smaller scale in Tanzania, India and a few other developing countries. Unlike other forms of aquaculture, seaweed farming...
The introduction of culture-based fisheries (CBF) in small scale irrigation systems is increasing the marginal value of water in rice farming. The amount of water that is used in Sri Lanka for rice farming could be utilised to generate more profitable non-crop economic activities such as CBF. This paper examines...
In this presentation, the author explores the research question - "Under what conditions can farmer-owned co-ops seize control of breeding and contribute to genetic diversity?" He uses case studies of breeding strategies in Norwegian husbandry and aquaculture.
In this paper, we estimated the costs and benefits of keeping pension fishers in the community. 34% of the 200 thousand fishers in Japan are over the age of 65. Since the fishers over 65 are pensioners, their fishery income is an additional source of livelihood. The average yearly income...
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,...
Over 90% of global aquaculture production comes fro
m the Asia Pacific region. International trade in live
aquatic animals and the intensification of aquaculture practices over the past several years have led
to
emergence and spread of several aquatic animal diseases in the region. At the same time, while the...
Disease is a primary threat to the continued growth in salmon aquaculture due to its extensive effects on the sector. Aquaculture farms suffer the most direct and immediate economic losses through reduction in growth, low feed efficiency and market prices, increasing mortality rates, and expenditures on prevention and treatment measures....
Disease control decisions at a sector level often reflect different types of goals and incentives between various stakeholders. While government may pursue policy objectives to eliminate disease at any cost, for example, the success of such initiatives relies on the capability and desire of industry to adopt such measures as...
Different methodologies have been used in modeling the epidemiology and economics of aquaculture diseases, including input-output models, benefit-cost analysis, linear programming, simple spreadsheetbased models, compartment models based on differential equations, and spatial models. Despite the advantages that these models provide, there is a need to develop a more integrated approach...
