| The Eastern tuna and billfish fishery (ETBF) is currently managed through an input quota system based on individual transferable effort units (the number of hooks) and a total allowable effort level (i.e. total number of hooks) A spatial management policy based on a series of differential hook-penalties has been proposed as a flexible tool to discourage vessels operating in certain areas (e.g. those with high bycatch potential) and encourage operating in other areas (e.g. with less bycatch potential). In this study, the importance of catch rates per hook to location choice is assessed through the estimation of a nested multinomial logit model. Other variables in the model include distance to the location, prices of the main species, fuel prices and vessel... |

| Fishers are faced with multiple risks, including unpredictability of future catch rates, prices and costs. While the latter are largely beyond the control of fisheries managers, effective fisheries management should reduce uncertainty about future catches. Different management instruments are likely to have different impacts on the risk perception of fishers, and this should manifest itself in their implicit discount rate. Assuming licence and quota values represent the net present value of the flow of expected future profits, then a proxy for the implicit discount rate of vessels in a fishery can be derived by the ratio of the average level of profits to the average licence/quota value. From this, an indication of the risk perception can be derived,... |

| Agricultural development in both the United States and Australia has led to suboptimal levels of environmental degradation. While both countries face similar forms of agricultural environmental degradation, the different resource endowment and population distributions have resulted in a different incidence of the costs of these problems. Increasing demand for environmental services and better information on off-site damages have led to increasing demand for reform of agricultural, rural development, and environmental programs to eliminate biases against practices viewed as more environmentally compatible. |

| Using the example of commercial fishing, this paper explores the potential of incentive based management measures as a means of reducing the undesirable impacts of industries operating within the marine environment. Despite having been successfully applied for similar purposes in the management of terrestrial environments, and their potential to achieve environmental gains in an economically efficient manner, examples of incentive based management mechanisms are still relatively limited in the marine context. We assess the potential of a number of alternative market based management measures by reviewing and considering the successes and limitations of previous applications and how these would translate in the case of commercial fishing. Several fishing... |

| Economic surveys of fisheries are undertaken in several countries as a means of assessing the economic performance of their fisheries. The level of economic profits accruing in the fishery can be estimated from the average economic profits of the boats surveyed. Economic profits consist of two componentsresource rent and intra-marginal rent. From a fisheries management perspective, the key indicator of performance is the level of resource rent being generated in the fishery. Consequently, these different components need to be separated out. In this paper, a means of separating out the rent components is identified for a heterogeneous fishery. This is applied to the multi-purpose fleet operating in the English Channel. The paper demonstrates that failing... |

| Intensive aquaculture, especially the production of carnivorous species, requires artificial feeding. Fishmeal and oil are preferred to vegetable proteins, since marine proteins provide the essential nutrients required by farmed fish. Therefore, given the stagnant production of reduction species and the rapid increase in aquaculture production, fishmeal availability would pose a biological constraint on aquaculture contribution to world fish supplies in the future, unless alternative feed sources can be incorporated in diets. In this paper, the technical substitutability between fish and vegetable based feeds are assessed through the estimation of Morishima elasticities of substitution. These are derived from a meta-analysis production function. |
