Lumpfish (Cyclopterus lumpus) are used as cleaner fish in salmon aquaculture to treat sea lice. However, after 18–24 months and reaching 0.4–0.6 kg, the fish is removed from the salmon cage and usually discarded, which raises social, economic, and environmental challenges, as well as ethical concerns. This paper assesses the viability of marketing lumpfish as food by exploring possible products that can be made from the fish in Vietnamese cuisine, and understanding the stakeholder’s perception and acceptance of the fish.

What drives the substitution of hazardous flame retardants in electronic appliances in Sweden?

Highlights

  • We identify the relative importance of different drivers of firms’ preferences for chemical substitution.
  • The avoidance of health and environmental hazards is the most important driver of chemical substitution.
  • Firms are reluctant to tax policies that might lead to increases in the price of the product being sold.
  • Reluctance to chemical taxes can be reduced by using labels disclosing the use of less hazardous chemicals in the products.

The seafood processing industry plays a vital role in job creation and economic growth, particularly in regions like the Mekong River Delta of Vietnam. However, this industry also generates a significant amount of organic pollutants, predominantly discharged into riverside and seashore areas.

Consumers’ willingness to pay an environmental fee for e-waste recycling in Vietnam: integrating the theory of planned behaviour and the norm activation model

Hoa, Dang Le

E-waste is becoming a concern due to its toxic content and serious pollution effect. Many studies have focused on the detrimental impacts of hazardous e-waste and extended producer responsibility for e-waste recycling. There is, however, a lack of case studies from the perspectives of consumers’ awareness of e-waste, and willingness to pay (WTP) for e-waste recycling. An e-waste management system cannot be efficient when consumers are not actively involved in.

How can organisations in developing countries support waste pickers for increased recycling in low-income communities? A South African product responsibility organisation uses subsidies and administrative support in a business model approach

Key Points 

  • Recycling can be promoted in low-income communities through a business model framework 
  • Business models for recycling efforts in low-income communities need financial and administrative support for sustainability in the short to medium term. 
  • There is no one-size-fits-all approach to such a business model framework. The model must be adapted to fit the community’s needs

Ghost fishing gear and their effect on ecosystem services – Identification and knowledge gaps

Submitted by Luat Do on
EfD Authors:
Huu-Luat, Do

Abandoned, lost, and discarded fishing gear (ALDFG) is claimed to be a global problem with impacts on marine animals and ecosystems, posing considerable ecological and socioeconomic challenges. Nonetheless, insufficient understanding regarding how marine ecosystem services are affected by ALDFG creates a knowledge gap that challenges a holistic estimation of the long-term economic impacts of using non-degradable fishing gear.

Abundance of Resources and Incentives for Collusion in Fisheries

Carlos Rosas Muñoz, Juan

The aim of this study is to explore theoretically the circumstances in which collusion can emerge between artisanal organizations and external agents. We also analyze theoretically how collusion can alter the sustainability equilibria of marine resources. In situations of incomplete information where external agents are not aware of the initial stock of resources, we observe how those agents decide whether to accept or reject offers of collusion from artisanal organizations.
