    A Review of Caribbean Ecosytems and Fishery Resources Using ECOPATH Models by S.G. Smikle, V. Christensen, K.A. Aiken

    Published 2010-03-01
    “…This paper provides a review of ecosystems modelling within the Caribbean using the Ecopath approach and software tools. The review is not intended to provide a direct comparison of the modelled ecosystems attributes and performance, as this would require having access to the models and the data sets used to build the models. …”

    Ecosystem attributes of trophic models before and after construction of artificial oyster reefs using Ecopath by Xu, M, Qi, L, Zhang, Lb, Zhang, T, Yang, Hs, Zhang, Yl

    Published 2019-03-01
    “…We provide that assessment, including trophic interactions, energy flows, keystone species, ecosystem properties and fishing impacts, through a steady-state trophic flow model (Ecopath with Ecosim). The model estimated values of 4721.2 and 4697.276 t km-2 yr-1 for total system throughput and 534.74 and -519.9 t km-2 yr-1 for net system production before and after AR deployment, respectively. …”

    A preliminary model of the mangrove ecosystem of Dongzhaigang Bay, Hainan, (China) based on Ecopath and Ecospace by Chengpu Jiang, Daniel Pauly, Wenqing Wang, Jianguo Du, Jianhua Cheng, Mao Wang

    Published 2023-11-01
    “…IntroductionMarine and coastal ecosystems are complex, especially because of the connection between their many functional groups and the various habitats provided by subsystems.MethodTo describe the trophic interactions, energy flows, and spatial distribution of species in the ecosystem of Dongzhaigang Bay, in Hainan, China, 28 functional groups were identified, incorporated in Ecopath and Ecospace models, and used to derive the particle size and spatial distribution of the functional groups.ResultThe results show that the trophic levels of top predators are lower than in similar ecosystems, but that the ecosystem of Dongzhaigang Bay exhibits a high ecotrophic efficiency, leading to a high fraction of its primary and secondary production being transferred to the higher trophic levels. …”

    Assessing the Fishing Impact on the Marine Ecosystem of Guishan Island in the Northeastern Waters of Taiwan Using Ecopath and Ecosim by Chien-Pang Chin, Kuan-Yu Su, Kwang-Ming Liu

    Published 2023-12-01
    “…To construct the marine ecosystem and to examine the interactions among trophic levels of fisheries resources in the waters of Guishan Island, historical catch, catch composition, biological information, fishing effort, environmental data such as sea surface temperature, salinity, and nutrients were analyzed using Ecopath with Ecosim. The results indicated that the longline and drift net fisheries have a very minor incidental catch of cetaceans, with a fishing mortality (F) of 0.01 year<sup>−1</sup> and an exploitation rate (E) of 0.03. …”

    EwE-F 1.0: an implementation of Ecopath with Ecosim in Fortran 95/2003 for coupling and integration with other models by E. Akoglu, S. Libralato, B. Salihoglu, T. Oguz, C. Solidoro

    Published 2015-08-01
    “…Societal and scientific challenges foster the implementation of the ecosystem approach to marine ecosystem analysis and management, which is a comprehensive means of integrating the direct and indirect effects of multiple stressors on the different components of ecosystems, from physical to chemical and biological and from viruses to fishes and marine mammals. Ecopath with Ecosim (EwE) is a widely used software package, which offers capability for a dynamic description of the multiple interactions occurring within a food web, and, potentially, a crucial component of an integrated platform supporting the ecosystem approach. …”
