TL;DR: It is likely that IMTA must generate substantially greater profits than salmon monoculture to stimulate investment and may benefit from alternative assessment methods such as the real options approach that explicitly incorporate uncertainty.

TL;DR: In this article, the authors used Data Envelopment Analysis (DEA) to examine the issues of efficiency and capacity utilization in the grow-out finfish industry in Malaysia, and found that most farms are technically efficient, but many are operating at lower levels of capacity utilization.
Abstract: Sea bass (Lates calcarifer) is a key aquaculture species in Malaysia, produced as part of a polyculture system in cages but predominantly as a single species in ponds. The production of sea bass in Malaysia has decreased substantially since 2015. Several studies suggest disease may be the main cause for such decline, but changing economic conditions may also have played a role in this decline. In this paper, we use Data Envelopment Analysis (DEA) to examine these issues as well as identify the key drivers of efficiency and capacity utilization in the grow-out finfish industry. Our results suggest that most farms are technically efficient, but many are operating at lower levels of capacity utilization. Socio-demographic factors appear to affect pond production but less so cage production. The results suggest that the reduced output of sea bass is largely in response to changed economic conditions (output and input prices).

TL;DR: In this paper, primary data from 325 fish farming groups in Sri Lanka were used to estimate a stochastic translog production frontier and found that technical efficiency in these irrigation systems was generally low, and substantially lower than that of other aquaculture production systems in other Asian countries.
Abstract: Despite the growing popularity of culture-based fisheries (CBFs) associated with village irrigation systems (VISs) in Sri Lanka, there is less knowledge about factors that influence productivity levels. CBFs compete with rice for access to water in the VIS, so maximizing the efficiency of CBFs is essential to ensure that the limited water resources are used most effectively. To address this, primary data from 325 fish farming groups were used to estimate a stochastic translog production frontier. Technical efficiency in these irrigation systems was found to be generally low, and substantially lower than that of other aquaculture production systems in other Asian countries. This suggests that production can be increased substantially with better management using existing technology and resources. Removing subsidies, improving consultation with extension officials and improving water user rights – in particular, the introduction of a transferable community quota system – were found to be key means for improving efficiency.
