  Citation × Citation Citation Abstract Copy Title: The Spanish Hake Market: Relationships Between Different Hake Products Author: Franquesa, Ramon, Guillen, Jordi Seafood consumption has been traditionally very important in Spain (about 36.5 kg per capita consumed in 2003). Hake (merluza) is the main fish species consumed in quantity and value terms in Spain. But commercialised as hake can be found several fish species and presentations. When many papers focus on product aggregation and market integration for several whitefish species using somehow aggregated data; the present study questions the product aggregation on one species, hake, depending on size, gear, origin, etc., by using disaggregated data on several markets in the Spanish market chain. Then, as most economic time series are non-stationary, cointegration is employed to examine the relationships between the different hake products.

Two species of the Indo-Pacific lionfish (Pterois miles and P. volitans) have rapidly expanded throughout the Gulf of Mexico, mid- and south Atlantic and the Caribbean following their introduction to Florida coastal waters during the mid-1980s through releases from marine aquaria. There is overwhelming scientific agreement on the threats that this invasion poses to a wide range of native species, including grunts, snappers, and groupers. Because eradication of lionfish is unfeasible, scientists and conservationists are urging the implementation of lionfish management plans in order to reduce the environmental and economic impacts of the invasion to a manageable scale. Recent studies indicate that persistent removal of lionfish by spearheading does help control lionfish populations and help native fishing rebound. Through mathematical modeling and field tests, researchers have found that reducing lionfish stocks by about 75 to 90 percent leads to the rapid recovery of native fish numbers (Green et al. 2014). Data on prey fish and lionfish densities as well as spearheading catch rates were collected from lionfish derbies held at the Bacalar Chico Marine Reserve, Belize, in 2014. These data were used to estimate reef-specific target lionfish densities leading to the recovery of native prey species in the marine reserve as predicted by the Green et al. (2014) model. The fishing costs involved in reaching the target densities were also estimated to evaluate the overall effectiveness of manual removal techniques as a management strategy for invasive lionfish stocks.

  Citation × Citation Citation Abstract Copy Title: Do Fishermen Bother With Bycatch Avoidance?: Evidence from the Eastern Bering Sea Author: Abbott, Joshua, Wilen, James The incidental catch of non-targeted species is a significant issue in fisheries management. Most current approaches to bycatch control have viewed it as a purely technological problem; however, there is growing evidence that fishermen are able to control their bycatch, albeit at a cost, by their choice of where to fish. To examine the propensity of fishermen to spatially determine their bycatch, we examine the bycatch of halibut in the multispecies head and gut fishery of the Eastern Bering Sea. Both bycatch and target species removals are governed through a system of seasonal multispecies quotas (enforced by fishery closures) that are commonly held by the fleet. Both economic theory and the history of the fishery suggest that this method of control fosters a race to bycatch in which the intrinsic value of a unit of bycatch avoidance is far too low relative to that desired under the rent-maximizing policy. This should result in foreshortened seasons and forced closures due to excessive bycatch rather than from the full exploitation of the target species' quota. To examine these predictions, we augment a traditional random utility model of fishing location choice with measures of expected bycatch as well as the usual measures of expected revenues and steaming costs. We utilize six years of spatially and temporally disaggregated vessel-level data from the North Pacific Groundfish Observer Program to estimate the model. We are then able to estimate the implicit shadow value of bycatch to fishermen and conduct inference on its magnitude. Preliminary results suggest that the shadow value is indistinguishable from zero - a finding which concurs with our theoretical predictions for a fishery of this size. Finally, we assess the incentive effects of a voluntary bycatch avoidance system participated in by some fishermen by comparing the estimated shadow values before and after the program across participating and non-participating groups.
