Creator:: Chen, Allen and Haynie, Alan
Abstract:: Bioeconomic modeling of an age-structured population typically assumes the value of a fish increases with size; the fish increase in weight as they age, and harvesters may receive an increase in the price per weight. When size selectivity is possible, traditional policy such as individual quotas may still result in...

Creator:: Chen, Allen, Haynie, Alan, and Ianelli, Jim
Abstract:: We describe the dynamics by which competing harvesters selectively target prime market-sized fish, without internalizing the externality of increasing targeting costs, as the abundance of prime fish decreases. Due to the increasing targeting costs for prime size, harvesters continually target the next-most-desirable size fish, gradually fishing down the size structure...

Creator:: del Valle, Ikerne, Astorkiza, Immaculada, and Astorkiza, Kepa
Abstract:: A primal formulation has been used to estimate a translog production function that includes fishing effort and fisherman’s skill as production factors. The selected functional form permits the analysis of the substitution possibilities among production inputs composing effort by calculating the Allen elasticity of substitution. Particular attention is paid to...

Abstract:: This work reports on the implications of an extreme climatic event among owners of fishing grounds in the spiny lobster (Panulirus argus) fishery of Punta Allen, Mexico. This MSC certified small-scale fishery is co-managed through Territorial User Rights. Members of the fishing cooperative, have exclusive access to individual fishing grounds...

Abstract:: Considerable attention has been applied to the development of models explaining how fish stocks change over space and time, from relatively simple stock-recruitment relationships to ecosystem models with a complex food web structure. However, in many case studies fishing effort is assumed to be exogenous and even in dynamic models...

Abstract:: The growth of tiger shrimp P. monodon and physicochemical factors of pond water and sediment were observed in tropical climate using bacterial products called probiotics. No improvement in shrimp growth and water quality was noted compare to other reported studies. The organic matter (OM) and total sulfur (TS) of pond...

Creator:: Barnes-Mauthe, Michele, Lynham, John, Kalberg, Kolter, and Leung, PingSun
Abstract:: Pelagic fishers operate in a dynamic environment and are faced with a high level of uncertainty on a daily basis. To cope with this complexity, fishers often rely on sharing information with others in order to improve their decision making. Yet previous research has not explicitly investigated the effect of...

Abstract:: Tuna fisheries around the world are governed by Regional Fishery Management Organizations (RFMOs), whose membership includes both harvesting nations and nations in whose waters the targeted fish populations reside. The outcomes of the policies established by an RFMO will depend on subsequent interactions among the fleets, the fishing sites and...

Abstract:: This presentation explores the interaction of the fishery sector and the emerging push for marine biodiversity conservation. These are viewed as two ‘streams’ of governance – flowing through global bodies (notably the United Nations), through nations (with interacting environmental and fisheries agencies), and through thousands of coastal communities worldwide (which...
