Type: Journal Article
The South China Sea is an important fishing area with an annual harvest of some 5 million tonnes, or 10% of the catches jointly taken by the developing nations of the world. Details are given of a model of the area describing ...
Trophic models of aquatic ecosystems
Type: Conference Proceedings
A large proportion of the contributions to the ICES Theme Session on "Trophic models in aquatic ecosystems" is presented, together with papers of a number of scientists and very experienced ecosystem modellers.
Fish production, catches and the carrying capacity of the world oceans
Type: Journal Article
A brief review of the status of the world fisheries is presented with emphasis on the differences between catches (= landings + bycatch), biological production of fish, and predation (= production - catches). The ECOPATH ...
Structuring dynamic models of exploited ecosystems from trophic mass-balance assessment
Type: Journal Article
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 defining trophic interactions as ...
