  Citation × Citation Citation Abstract Copy Title: Alaska Mariculture Initiative–Why not Alaska? Six Economic Case Studies of Successful Mariculture Industries and Their Potential Relationship to a Statewide Strategic Plan to Develop Alaska’s Industry Author: Decker, Julie, Wellman, Katherine The potential economic impact of a fully developed mariculture industry in Alaska is not well understood by industry or policy makers. It is also not entirely clear what is needed to move from Alaska’s current micro industry (approximately $500,000 in annual sales) to a fully developed industry. In general, the existing seafood industry (harvesters and processors) does not consider itself to be potential beneficiaries of mariculture development. Since the Aquatic Farm Act was passed in 1988, allowing for aquatic farming of shellfish and marine plants in Alaska, the stakeholders and agencies have not been acting in coordination to expedite the development of the industry, pointing to the necessity for a statewide strategic plan. The Alaska Fisheries Development Foundation (AFDF) is spearheading the Alaska Mariculture Initiative (Initiative), which will develop a clear and comprehensive statewide strategic plan. An important part of the Initiative is an economic analysis to inform the decisions to be made in the creation of the strategic plan. Phase I of the economic analysis will be six comparative case studies which outline examples of successful mariculture industries in different regions of the world with similar or relevant environmental and/or economic conditions to Alaska, including native species and potential stakeholders. The results of these case studies will be presented as well as their potential relationship to Alaska’s statewide strategic plan. Title: Alaska Mariculture Initiative–Why not Alaska?

  Citation × Citation Citation Abstract Copy Title: The Economics of Recirculation Aquaculture Author: Forster, Anthony, Rawlinson, Peter Year: 2001 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 to determine the relationship between key bio-economic variables such as the sale price of the product, FCR, stocking density and growth.

  Citation × Citation Citation Abstract Copy Title: The Effect of Oyster Farm on the Neighboring Housing Value in Rhode Island Author: Uchida, Hiro, Sudhakaran, Pratheesh O., Opaluch, Jim, Puggioni, Gavino From 2000 onwards, the United States saw an increasing trend for the shellfish aquaculture practices especially along the Northeast coast. Despite the supporting majority of public regarding the shellfish aquaculture operations, these operations are sometimes opposed by local communities claiming the devaluation of housing property due to the construction of oyster farm. Since the uproars against the devaluing of housing property is directly affecting the lives of public, it is critically important to study the effect of construction of oyster farm on its value. A difference-in-difference (DoD) model within hedonic price model (HPM) was used to evaluate the effect of oyster farm on property value. We collected the details of the oyster farms operated in Rhode Island from the Coastal Resource Management Council (CRMC). Our housing sales data lists all the housing transactions in Rhode Island between 2000 and 2013. We used a linear mixed model with lot size as unit level fixed effect and city as random effect. The result showed that the DoD coefficient associated with interaction of distance bands and the construction of oyster farm, was statistically insignificant. The statistical insignificance of the coefficients suggests that there is not much change in housing value due to the construction of oyster farm. The analysis shows that houses further away from coastline will reduce the value of the property. One of the caveats of this study is lesser housing transactions since the construction of oyster farm happened in recent years.

  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.
