The relationship between intrinsic fish quality (fish condition before handling), production efficiency, product price, and the optimal management of commercial "wild" fisheries was explored in four companion papers. The optimal management plan-consisting of quotas and harvest schedules - would maximize the discounted net industry revenues (NPV) given a minimum biomass...
The Florida spiny lobster trap certificate program (TCP) is one of the oldest U.S. fisheries programs involving tradable effort permits. Under the TCP, fishers must own a certificate (and pay an associated annual fee) for each trap used. The program was created in 1992 to address overcapitalization amid growing social...
The Gulf of Mexico Red Snapper IFQ Program (Program) was the first catch share management program implemented in the Gulf of Mexico. IFQ management was implemented to reduce overcapacity and eliminate the problems associated with derby style fishing. The Program was successful, the number of vessels harvesting red snapper decreased...
Despite the success of co-management policies and territorial use rights in achieving the sustainability of some small scale fisheries, a considerable part of them still operate under open access, with very limited management and monitoring (if any), and even facing the risk of overexploitation. As a result, fleet reduction and...
Catch share management programs are designed to reduce overcapacity in fisheries through trading as efficient harvesters buy out their less efficient counterparts. Numerous studies have looked at either the ex-ante potential of catch shares management to reduce overcapacity in a fishery or the ex-post effects of implementing such a program,...
During the first three years (2007-2009) of the Gulf of Mexico red snapper IFQ program most quota lease trades were local, involving fishers that lived in the same communities. In 2010, the red snapper quota lease market changed as more IFQ participants began trading quota with fishers from different regions...
Many of the tangible benefits of catch share programs (e.g., reducing overcapacity) are dependent on the trading of shares. Additional trading-related questions (such as whether landings will change port or be concentrated geographically) are also important to the overall evaluation of a fishery, but are often asked only during post-implementation...
The harvest technology of several multispecies fisheries has been explained in the recent literature using dual-based models. These studies are useful for explaining rent dissipation, estimating input and output elasticities, as well as describing other aspects of fisherman behavior. Most of these analyses have assumed that inputs are fixed at...
The saltwater aquarium hobby has increased dramatically in the last decade due to improvements in the technologies and knowledge needed to sustain mini-reef ecosystems. With this increased demand comes increased pressure on natural reef ecosystems that supply the vast majority of the live organisms for the commercial market. To combat...
Scanner data that’s collected on consumer purchases falls into two main groups: point-of-sale scanner data and household-based scanner data. Point-of-sale scanner data can identify the products that are purchased, the quantity sold, and the price of the product. Household scanner data comes from a sample of survey participants that scan...
