“…However, geological differences may affect the growth conditions of fingerlings, and the economic levels of the different countries may affect the production input capabilities of the farms. Huang et al (2008) and Miao et al (2002Miao et al ( , 2009 reported that cost inputs and economic efficiencies of the culture industry may vary due to the different production regions. Therefore, this study collects ecological and economic variables of cobia farming in Taiwan, China, and Vietnam and employs multivariate statistical analysis in order to compare the culture industry production and economies of the regions in order to determine the key factors of production efficiency and provide reference for future cobia culture investors.…”

In recent years, cobia has become an emerging farmed species in Asia due to its quick growth and high economic value. This study collects biological and economic data affecting the economic performance of cobia farming in three countries, namely Taiwan, China, and Vietnam. The data are collected by questionnaire sampling and analyzed by multivariate statistical analysis in order to compare the key factors affecting the production and economy of cobia farming in these three countries. The results show that Taiwan, China, and Vietnam have significant differences in input intensities and profitability. China has the highest input intensity (3372.42 TWD/m 3 ), as its high stocking density increases feed input. Taiwan has the highest unit input cost (103.44 TWD/kg), as the high quality of the product increases the price of cobia in Taiwan, which offsets the high product costs. In terms of profitability, the benefit-cost ratio is over one in all three countries, indicating that the profitability of cobia farming is good in all three countries. Profitability analysis shows that fingerlings in China achieve 36.50, which is the highest among the three countries; whereas Taiwan has the highest feed profitability of 0.78, which reveals that the fingerlings produced in China are competitive in both price and quality, while Taiwan has the best feed management efficiency. The production costs and profitability of Vietnam fall between those of Taiwan and China. Feed cost is the main expenditure in cobia culture; thus, good feed management could effectively reduce production costs and increase business performance. The feed quality and input management model of Taiwan, in conjunction with the fingerling quality and stock model of China, could provide future reference for farming management in such areas as feed input and selection of fingerling.

“…A production cost in aquaculture can be divided into two parts, fixed and variable costs. Since most systems of pond culture in Taiwan are quite old (over 15 years or even more), the farming cost contains a large percentage of the variable costs, including feed, fry, water and electricity, which account for more than 65% of the production cost (Miao and Tang 2002). Unlike traditional pond culture in Taiwan, the cost structure in cobia production indicates that feed, fixed cost, fingerling and labor in that order are the major costs (inputs) in the cage culture.…”

“…The fixed cost for traditionally inland aquaculture in Taiwan is not a major expense (Miao and Tang 2002). Unlike the inland aquaculture, the fixed cost accounts for a substantial part of the production cost in Taiwan's cage culture.…”

“…These manufactured cages involve high end technologies to protect them from high winds and strong currents, therefore they are very expensive. The variable costs such as fry and feed are the most significant expenditures in intensive aquaculture (Miao and Tang 2002). The variable cost consisting of fry (20.46%), feed (35.24%), water and electricity (9.70%) accounts for more than 65% of the production cost in Taiwan's grouper farming (Miao and Tang 2002).…”

The structure of cost and return for cobia cage culture in Taiwan was studied by considering two major factors, geographical location and production scale. Although the geographical location had little influence on the input intensities, the production scale would have a significant impact on the cost structure. However, the performances of profitability were significantly affected by not only the individual main effects but also their interaction. As a result, the studied effects on the cost and return were quantitatively estimated by a series of statistical models, in turn quantitatively measured by a set of indices. A short-term strategy of the management suggested that the best choice regarding profitability is to locate the farming system with a large-scale operation in the coastal waters of Pindong. Additionally, the profitability could be further increased by selecting better quality fingerlings and feeds based on a set of the computed indices. A long-term strategy of the management strongly recommends that to increase the system size in cobia production would be much more profitable due to the positive economies of scale. Finally, a future study shall be interested in whether current speed has a limiting effect on the profitability.
