In 1990-1993 in Kapasia sub-district in central Bangladesh ICLARM introduced low-input aquaculture for pond owners to adapt into their farming systems. Impacts on production, fish consumption and markets were assessed in 1998-1999. The percentage of ponds stocked increased from 1990 to 1998, but did not differ significantly between past participants...
Following an assessment of Mexican water resources by governmental agencies in the late 1940’s, Tabasco State was identified as a potential area for aquaculture development, as the State holds 30% of National water resources and an important share of Southeast Mexican fisheries, particularly for oyster production. However, conflicts and competition...
This paper examines the circumstances under which farmers respond to the introduction of tilapia production technology, and analyzes the manner in which the benefits from such introduction are shared and distributed among recipients. The hypothesis that the inverse relationship between yields and operational land size widely observed in agriculture is...
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....
This paper investigates the financial and economic efficiencies of three scales of recirculation aquaculture production growing Murray Cod (Maccullochelli peelli peelli) at tonnages of 25 tonne, 50 tonne and 150 tonne. Best practice industry data is used (growth, FCR, mortality, equipment and running costs) in conjunction with AQUAFarmer feasibility software1...
U. S. agriculture is at a crossroads. The value of traditional agricultural exports has fallen while imports have increased. Concerns about the environmental impacts of current agricultural practices threaten profitability. As O'Connell (1989) pointed out in Choices , one answer to U. S. farm problems might be found in the...
Traditional aquaculture has to a large extent used herbivore species with limited requirements for additional feeding. However, in intensive aquaculture production one farm carnivore species like salmon and also feeds herbivore species with fishmeal as this increase growth. This has lead to a growing concern that increased aquaculture production poses...
Bleach has been used for decades as an irritant in the British Columbia (BC) commercial octopus dive-fishery. Recently the FAO (United Nations Food and Agriculture Organization) declared that using noxious substances in any fishery is considered unlawful, under international law. Canada’s Department of Fisheries and Oceans (DFO) has asked BC...
A linear programming (LP) profit-maximization model and a Target MOTAD risk programming model were developed to identify optimal management strategies and associated risk levels for the aquaculture of penaeid shrimp in Honduras. Data for this study were provided by three cooperating shrimp farms and included complete production records of 1,004...
This paper analyses the factors explaining productivity and efficiency differences across salmon aquaculture farms, with an emphasis on agglomeration externalities. We specify a stochastic frontier production model with agglomeration indexes included in both the frontier production function and the technical inefficiency model. The frontier model is estimated on a rich...
