State of the stocks and change in the abundance of demersal fisheries resources in the member countries of the CSRP
MetadataShow full item record
This communication presents a synthesis of the work undertaken within the framework of the FIAS project, by the “Single-species Analysis” module. This work focuses on statistical analyses of commercial fishing and the data from scientific trawling surveys, in order to deduce the current state of exploited stocks and to better understand the ecosystems of the sub-region. This relates to the analyses of about 20 stocks, distributed in the waters of the various countries and covering a broad range of ecological characteristics. Three approaches were used: (1) analyses of a time series of estimates of abundance indices obtained from GLM-type methods applied to survey or commercial data; analysis of a time series of catches and catches per unit of effort used in production models of fisheries dynamics; cohort analysis and biomass and recruitment models. These single-species analyses, used through comparative ecology, are supplemented by the study of the evolution of abundances o.....
