However, in many situations the construction of a biomass budget for a box model of an ecosystem is relatively simple and can provide important information about the ecosystem standing stock and energy flow. The ECOPATH model is an analytical procedure to estimate a biomass budget for a box model of an ecosystem given inputs which specify the components of the ecosystem, together with their mortality, diet, and energetics value. A computer program for ECOPATH has been written in BASIC-80, version 5.21, by microsoft (CP/M version).</style></abstract><accession-num><style face="normal" font="default" size="100%">1454265</style></accession-num><notes><style face="normal" font="default" size="100%">1985English</style></notes><auth-address><style face="normal" font="default" size="100%">Southwest Fish.
