Economic analysis of technological innovations to improve sustainability of pangasius production in Vietnam

Factors affecting the quantity and quality of faecal waste in striped catfish

“…So far, few studies are available on the digestibility of feed for striped catfish (Hien et al, 2010;Da et al, 2013) and even few studies address the waste management in striped catfish. Improving feed digestibility may imply that feeds will cost more money (Ngoc, 2016). However, specifically for the case of striped catfish culture, the feed price may hamper farm profitability and the willingness of farmers to use such feed.…”

“…In addition, if the production costs of the fish increase, because of using feeds with low amounts of NRF, can these increased prices be transmitted through the value chain and eventually be paid by the consumer? Ngoc et al (2016) demonstrated symmetric price transmission for frozen pangasius fillets throughout the value chain, which would offer farmers an equal bargaining power when negotiating price increases due to increased production costs. Therefore, it is very well possible that striped catfish consumers would be willing to pay for these extra costs if it was clear that the environment in Vietnam would benefit from it or if it would contribute to a more sustainable form of catfish production.…”
