Production has been calculated using the other parameters : P=C-E-R.

See American Alligator references in the Cypress Wetland network.

A 2.5 m captive crocodile consumed 1100 g wet w of mullet per day.

A 4.8 m crocodile consumed 8000-26000 g/day.

  Day et al. 1990.

Consumption / Biomass ratio: 6.5

See American Alligator references in the Cypress Wetland network.

Assimilation efficiency: 80%

These ratios represent the proportions of consumption we partitioned to each of the metabolic parameters. They are based on our original calculations and not on the balanced numbers presented throughout these web pages. They should assist you if you are interested in calculating a production value for the top consumers in the system whose balanced production values are zero.
