Consumers are willing to pay more for HAB-free mussels

Submitted by Meseret Birhan… on

Key Messages
●    Consumers may avoid consuming mussels if they perceive a high risk of HAB contamination, even under government monitoring.
●    HABs have significant welfare losses for consumers, but policies to ensure food safety in seafood markets can improve social welfare.
●    Perceptions about HABs and mussel attributes play a role in explaining consumer preferences, but the link varies across contexts.

Submitted by Luat Do on
EfD Authors:

As the world’s largest producer of fish, China has faced significant challenges in developing its fisheries. Over the past four decades, China has implemented and adjusted multiple regulations and measures to reverse the decline of aquatic resources and achieve sustainable fisheries. This study analyzes the production trends and efforts during the period 1980–2019, highlighting the key features of and structural shifts in China’s fisheries. Our results reveal a significant shift in seafood production from capture to aquaculture and from offshore to inshore waters.

Economic values for ecosystem services: A global synthesis and way forward

Submitted by Luat Do on
EfD Authors:

This paper presents a global synthesis of economic values for ecosystem services provided by 15 terrestrial and marine biomes. Information from over 1,300 studies, yielding over 9,400 value estimates in monetary units, has been collected and organised in the Ecosystem Services Valuation Database (ESVD). This is a substantial expansion of data since the de Groot et al. (2012) description of the ESVD and provides an important juncture to explore developments in the use of valuation methods and the contexts in which valuations are conducted.

Exploring fishers' pro-environmental behavioral intention and support for policies to combat marine litter in Vietnam

Submitted by Luat Do on

This study applies Value-Belief-Norm (VBN) theory to investigate fishers' pro-environmental behavioral intention and their support for policies to reduce marine litter. While pro-environmental behavioral intention is often associated with personal environmental intention at the household level, policy support represents their support for government action at the political level. Therefore, we examine whether fishers are willing to engage in both of these dimensions. Data from 369 Vietnamese fishers are analyzed using structural equation modeling with FIMIX-PLS and PLS-POS.

What drives stocking density decisions in the Chilean salmon industry? A retrospective analysis of stocking regulations

Submitted by Belén Pulgar on
EfD Authors:

According to Chilean legislation, a salmonid concession holder must choose between two mutually exclusive stocking density systems: Stocking Reduction Percentage (SRP) or Stocking by Density. This study identifies the main determinants in the choice of stocking system and estimates their marginal effects. The results suggest that if the previously stocked species is Atlantic salmon (Salmo salar), the probability of stocking by SRP increases by 36.6%.
