This research examines bargaining power in the market for Northeast
Multispecies Days-at-Sea (DAS). In 2004, the DAS system was converted
to a tradable input control system. Characteristics of the program include:
1) trading restrictions based on length and power to limit increases in
output, 2) prohibitions that limit the ability...
The coastal ecosystem of the Pearl River Estuary (PRE) has been overfished and received a high level of
combined pollution in the past decades. The fisheries stock assessments have shown a declining
population and have led to a number of management measures, including fishing moratorium. This study
evaluated the effect...
Seafood ecolabel, such as Marine Stewardship Council (MSC) label continues to expand worldwide,
particularly in European and US markets. Consumers’ response to ecolabeled seafood products in these
markets has been studied in the past, mostly with encouraging results. Meanwhile, and after a decade
since the establishment of MSC, seafood ecolabel...
This research investigates the ex-vessel price flexibility of U.S. Pacific
sardine landings using a price response analytical framework. Under
perfectly competitive market conditions, we would expect to observe an
inverse relationship between the average price and the aggregate quantity
supplied. However, affiliations between U.S. Pacific sardine harvesters and
processors, as...
It was obtained the optimal rotation time for the polyculture of tilapia
nilótica and white shrimp in freshwater, with a bioeconómic model. Data
for modelling were extracted from an experiment conducted in
CINVESTAV-IPN, unit Mérida, during the summer of 2008. The stocking
densities studied were 32.2 tilapia/m3 and 33.7 and...
This study explores the optimal harvesting time in a size-heterogeneous population dynamics. The model includes the effect of population density in both the mortality rate and individual growth. An application to specific conditions of shrimp culture in Mexico is presented. The optimal harvesting rule is numerically found for different economic...
