Catchability: a key parameter for fish stock assessment
SummaryCatchability is a concept in fishery biology which reflects the efficiency of a particular fishery. Its quantitative magnitude is expressed by the catchability coefficient, which relates theExpand

Flows of biomass and structure in an exploited benthic ecosystem in the Gulf of California, Mexico
Abstract We constructed a mass-balanced model of a benthic ecosystem exploited by shrimp trawlers in the Gulf of California, Mexico. The model is based on the software ecopath with ecosim Version 4a,Expand

Ecosystem trophic structure and energy flux in the Northern Gulf of California, México
Abstract Using the Ecopath with Ecosim software, a trophic structure model of the Northern Gulf of California was constructed to represent the main biomass flows in the system. It was based mostly onExpand

Energy flow and network analysis of Terminos Lagoon, SW Gulf of Mexico
The food web in Terminos Lagoon, south-western Gulf of Mexico was dominated by the detrital pathway, with benthic invertebrates playing a significant role in transferring energy from detritus toExpand

Characterization of lithogenic and biogenic zones and natural enrichment of nickel in sediments of the Terminos Lagoon, Campeche, Mexico
Abstract The Terminos Lagoon is located in the south-eastern Gulf of Mexico and is ecologically and economically important due to its biological diversity of valuable fish and wildlife resources. ItExpand

Which forcing factors fit? Using ecosystem models to investigate the relative influence of fishing and changes in primary productivity on the dynamics of marine ecosystems
Fishing mortality and primary production (or proxy for) were used to drive the dynamics of fish assemblages in 9 trophodynamic models of contrasting marine ecosystems. Historical trends in abundanceExpand

Analysis of the ecosystem structure of Laguna Alvarado, western Gulf of Mexico, by means of a mass balance model
Abstract Alvarado is one of the most productive estuary-lagoon systems in the Mexican Gulf of Mexico. It has great economic and ecological importance due to high fisheries productivity and because itExpand

Simulated response to harvesting strategies in an exploited ecosystem in the southwestern Gulf of Mexico
The impact of some optimized harvesting strategies on ecosystem structure was investigated using a mass-balanced model of the ecosystem in the southwestern Gulf of Mexico, where there are four typesExpand

Trophic structure and flows of energy in the Huizache–Caimanero lagoon complex on the Pacific coast of Mexico
Abstract The Huizache–Caimanero coastal lagoon complex on the Pacific coast of Mexico supports an important shrimp fishery and is one of the most productive systems in catch per unit area of thisExpand
