Biomass Development and Fishers’ Vulnerability in Nigeria: Evidence from a Survey Dataset

Submitted by Nnaemeka Chukwuone on

/Biomass decline is a vital threat for small-scale fisheries, but lack of data affects our ability to understand both biomass development and fishers’ adaptation. This study contributes to the literature on cost-effective, survey-data-based methods in data-poor and development-oriented settings. Based on original survey data from Nigeria, we find that 58% of respondents perceive a decline in fish abundance, in particular top-predator biomass. However, we also find signs of strategic behavior by respondents.

Do Chilean imports lead prices in the EU mussel market?

Submitted by Cristóbal Vásquez on

The impact that added competition of imported mussels from Chile might have had on market prices is one of the main reasons given to explain the decrease in the economic performance of the mussel aquaculture sector in the European Union (EU) in the last two decades. This hypothesis has not yet been tested. In this article we test empirically for price leadership and market integration in the EU mussel market. We estimate a cointegrated vector autoregressive (CVAR) model for the French, Italian, and Spanish mussel import markets and test for price leadership.
