“…In other words, improvement of semi-intensive systems is achieved through better quality of supplementary feed and improved feeding practices (Abdelghany & Ahmad 2002). The sensitivity of fish production costs regarding yield has been well documented (Engle 2010) and, while changes in pond management practices can improve fish yield, this does not automatically mean that these practices are economically rentable (Omondi et al 2001). In our study, we showed that supplementary feeding with an inappropriate type of feed could reduce farm profitability more than not using supplementary feeds at all.…”

Appropriate supplementary feeding is of increasing importance in common carpCyprinus carpio pond aquaculture, not only with respect to production issues but also as a sustainable tool for maintaining environmental quality. We studied the effect of different supplementary feeding regimes (no supplemental feed, cereal grains, pelleted feed, pelleted feed with lowered phosphorus content, and extruded feed) on growth performance, water quality, natural food availability, phosphorus budget, fish body composition and economic performance in 10 experimental ponds stocked with 3 yr old carp at a density of 363 fish ha −1 over a 4 mo period. The type of supplementary feed had no significant influence on water variables, with the exception of lowphosphorus pelleted feed which increased conductivity (p < 0.05). No significant differences were observed in zooplankton density. Harvested fish had significantly (p < 0.05) higher dry matter content and considerably higher phosphorus content under all treatments compared with fish at the beginning of the experiment. The use of cereals and extruded feed improved carp growth, while the physical qualities of the feed (higher resistance to nutrient leaching) resulted in lower nutrient concentrations in effluent water. Profitability was increased with application of cereal grains and decreased with all pelleted and extruded feeds. Hence, the use of cereal grain feed generated higher economic and environmental benefits than selected pelleted and extruded feed.

“…For instance, Iliyasu et al (2015) concluded, in an extensive review of technical inefficiency studies in aquaculture, that younger farmers may be less technically inefficient than their counterparts, presumably because of their higher willingness to adopt technological innovations. Regarding experience, more experienced farmers may make better managerial decisions and may therefore be less inefficient (Engle, 2010;Iliyasu et al, 2015). Likewise, more educated farmers are generally less technically inefficient, possibly due to their open minds toward new technological information as well as better capability to access and process such information (Dey et al, 2005;Iliyasu et al, 2015).…”

Vietnamese pangasius farming needs to produce efficiently to compete in world markets. This study investigates the inputand output-specific technical inefficiency of Vietnamese pangasius farmers. First, we used a Russell-type (input-output) directional distance function to estimate the input-and outputspecific technical inefficiency. Second, we applied a bootstrap truncated regression to analyze the factors influencing these technical inefficiencies. Results show that the main challenges for enhancing the performance of Vietnamese pangasius production are inadequate use of capital assets (inefficiency of 42%) and improper methods to achieve higher fish yield (inefficiency of 30%). Input-specific technical inefficiency (pond area and feed) is negatively associated with the experience and education level of pangasius farmers. Location of the farm in a saltwater intrusion area is positively associated with the inefficiency of producing fish. Outcomes of this study are useful to identify successful strategies to minimize the use of inputs while simultaneously maximizing fish production.

“…The Oracle 1 Crystal Ball software was used to simulate NPV and profit using 1,000 iterations (Engle, 2010). The stochastic input variables were initial investment cost, annual yields, annual prices, and annual expenses, i.e., costs of fingerling, feed, labor, veterinary services, land use, sludge discharge, energy, repair and maintenance, and annual interest.…”

This study aims to analyze the economic feasibility of recirculating aquaculture systems (RAS) in pangasius farming in Vietnam. The study uses a capital budgeting approach and accounts for uncertainty in key parameters. Stochastic simulation is used to simulate the economic performance of medium and large farms operating with a traditional system or RAS. Data are obtained through structured surveys and a workshop in the Mekong River Delta. Results show that for large farms, net present value increases from an average of 589,000 USD/ha to 916,000 USD/ha after implementing RAS. Overall, the probability that RAS is a profitable investment is found to be 99% for both farm sizes. With RAS, the crucial parameters determining profitability are price, yield, costs of fingerling, feed, and initial investment. Findings on the robustness of the economic performance of RAS are useful to support public and private decision making towards increasing the sustainability of pangasius production.
