Six of the programs studied allocated quota directly to communities to ensure their ongoing participation in the fishery. For example, dedicating 5% to 20% of the shares to certain communities in British Columbia and Alaska enabled those communities to remain in the fishery (Fig. 12) [27], [132] and [133]. In Alaska, shares are set aside as Community Development Quotas (CDQs),

which require that all fishery earnings further community development. These facilitate investments in education, infrastructure, and fisheries-related industries, thereby easing the transition to catch shares in vulnerable communities [133]. In Selleckchem Vincristine an alternative model, the Northeast Multispecies Sectors program establishes seventeen cooperatives, each of which can be managed with different community interests in mind. Other community interests can also be aided in retaining quota allocation. For example, processor interests are sometimes addressed through direct compensation, cooperatives, or quota sharing [134]. The loss of part-time fishing jobs can be mitigated partially through

assisting new fisherman entrants in purchasing stakes in the catch share fisheries. Catch share fisheries are also allowed under the MSA to create limited loan funds through cost-recovery fees to help new entrants purchase quota. These programs can help bring fishermen and communities into the fishery that would otherwise not be able to do so [135]. In the Alaska sablefish and halibut fisheries, the North Pacific Loan Program receives approximately $5 million per year for this purpose [104]. Catch shares design can help to limit ownership selleck chemical concentration through regulatory caps. However, fishery concentration is more Lonafarnib ic50 a result of fishery economics than management system. Changes in the four firm concentration (a commonly used measure of industry concentration measuring the total market share of the top four firms) tend to be minimal in catch shares transitions (Fig. 13). Most concentrated fisheries either remain stable or experience negligible concentration gains (e.g., less than 6% in the New Zealand deepwater and Atlantic surf clam fisheries). The most concentrated catch share fisheries are

the same fisheries that were the most concentrated under traditional management (e.g., the New Zealand deepwater, New Zealand mid-water, the SCOQ fisheries, and others), maintaining their pre-catch shares concentrations of between 50% and 70% [14], [56], [65], [76], [83] and [136]. Overall, concentration is focused in fisheries with major economies of scale, independent of management approach. Fisheries requiring large capital investments in vessels or equipment tend to provide greater returns to the most efficient operators, reducing the number of owners even before catch shares. For example, the SCOQ fishery requires major investment in large dredge vessels, resulting in high ownership concentration even under traditional management.
