Ecopath with Ecosim: methods, capabilities and limitations
TLDR
EwE combines software for ecosystem trophic mass balance (biomass and flow) analysis (Ecopath) with a dynamic modeling capability (Ecosim) for exploring past and future impacts of fishing and environmental disturbances. Expand

Towards sustainability in world fisheries
Fisheries have rarely been 'sustainable'. Rather, fishing has induced serial depletions, long masked by improved technology, geographic expansion and exploitation of previously spurned species lowerExpand

Diet composition and trophic levels of marine mammals
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. Diet wasExpand

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.Expand

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 4.2Expand

Structuring dynamic models of exploited ecosystems from trophic mass-balance assessments
The linear equations that describe trophic fluxes in mass-balance, equilibrium assessments of ecosystems (such as in the ECOPATH approach) can be re-expressed as differential equations definingExpand

ECOPATH II − a software for balancing steady-state ecosystem models and calculating network characteristics
TLDR
We present an approach and a software that should be useful to fishery biologist or aquatic ecologist attempting to look at more than two species at a time . Expand

Ecosystem maturity - towards quantification
Abstract An attempt is made to rank 41 steady-state models of aquatic ecosystems on the basis of their maturity. Maturity is quantified using several of Odum's attributes of ecosystem maturity. It isExpand
