Towards sustainability in world fisheries
TLDR
Zoning the oceans into unfished marine reserves and areas with limited levels of fishing effort would allow sustainable fisheries, based on resources embedded in functional, diverse ecosystems.
Diet composition and trophic levels of marine mammals
TLDR
Standardized diet compositions were derived for 97 species of marine mammals from published accounts of stomach contents as well as from morphological, behavioural and other information to derive trophic levels, which can be used for ecosystem modelling and related studies.
Structuring dynamic models of exploited ecosystems from trophic mass-balance assessments
TLDR
The proposed ECOSIM approach will enable a wide range of potential users to conduct fisheries policy analyses that explicitly account for ecosystem trophic interactions, without requiring the users to engage in complex modelling or information gathering much beyond that required for ECOPATH.
Ecopath, Ecosim, and Ecospace as tools for evaluating ecosystem impact of fisheries
Since its development in the early 1980s, the mass-balance approach incorporated in the Ecopath software has been widely used for constructing food-web models of marine and other ecosystems.
Primary production required to sustain global fisheries
THE mean of reported annual world fisheries catches for 1988-1991 (94.3 million t) was split into 39 species groups, to which fractional trophic levels, ranging from 1.0 (edible algae) to 4.2
