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...
Pacific sardine (Sardinops sagax), which is a transboundary resource
targeted by Mexican, U.S. and Canadian fisheries, has exhibited extreme
decadal variability in its abundance and geographic distribution
corresponding to water temperature regime shifts within the California
Current Ecosystem. Our study develops a three-agent bioeconomic
framework that incorporates environmental effects on...
In the 1950s the Pacific sardine collapsed, and the fishery declined from a
historical peak of over 600,000 metric tons in 1936 to less than 100,000
tons after 1951 and was virtually nonexistent for 25 years (1965-90).
Despite this, the landings of sardine predators increased after the sardine
collapse and...
Long-term, naturally occurring cycles can cause significant shifts in marine
ecosystems referred to as regime shifts. While the new regime can be as
diverse and ecologically acceptable as that which it replaced, individual
species may completely disappear or be greatly depressed when a regime
shift occurs. In this work we...
