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.

In low-income food-deficit coastal countries, fish forms a critical source of animal protein. Yet, capture fisheries, which provide fish protein to the local populations, are typically overcapitalized and exhibit classical signs of biological overfishing, threatening the livelihoods of communities. With the high and increasing fishing pressure, the rate of stock depletion may continue to intensify, thereby tilting households’ preferences towards consumption of other types of animal protein depending on whether (or not) they have strong preferences for those types of protein.

ABSTRACT

Women's participation in small-scale aquaculture is growing, but women producers remain in a disadvantaged position compared to men. Reducing gender gaps is at the core of many development programs, but little is known regarding the source of these differences. This paper investigates the main drivers of gender gaps in seaweed small-scale aquaculture by focusing on the analysis of differences between male and women, and across a series of psychological traits.

Abstract

We study the development of aquaculture activities in Chile and the impacts of regulatory changes on location decision for aquaculture production centers. Our study considers a descriptive analysis on the spatial and temporal development of aquaculture production centers. Next, using a panel data we estimate a site selection model to explore determinant factors of site choices for aquaculture production. Our results suggest a clear pattern for the spatial-temporal development of Chilean aquaculture.

This study uses a choice experiment to characterize market segments (consumer preferences heterogeneity) based on three attributes of seafood (mussels) that are affected by ocean acidification: shell appearance, meat color, and nutritional composition. Using a sample of 1,257 individuals from two main cities in Chile, we estimate both the Mixed Logit model and the Latent Class model. We use the individual-specific posterior (ISP) parameters’ distribution to categorize consumers’ heterogeneity based on the signs and intensity (i.e., like or dislike dimension) of these ISPs.
