Dry season = 8.00E-06 animal/m2
Wet season = 4.00E-06 animal/m2
The numbers are based on Environmental
Impact of the Big Cypress Jetport (United States Dept of the Interior,
1969) and expert estimation (Dalrymple, G., pers. com.).
*For the wet season I
used half of the number I have for the dry season because I assumed that the
area in which this animal feeds and lives is less.*
Biomass per animal = 7850 g (wet weight)
dry weight/wet weight ratio (dw/ww) = 0.35
gramms of carbon/gramms of dry weight = 0.45
Jorgensen, S.E., et al., 1991.
Basal metabolism = 0.0132 Kcal/gww per day
Free living metabolism = basal metabolism x 2
Free living metabolism = Respiration = 0.0264 Kcal/gww*day
Mean food caloric content = 5.3 Kcal/g of dry weight
Mean food Carbon content = 45% of dry weight

P/B Production/Biomass ratio (P/B) = 0.58 yearly rate
Banse, K. and S. Mosher, 1980.
Egestion/Consumption ratio (E/C) = 0.20
Otters will feed on: Crayfish, Apple Snails, Terrestrial Invertebrates,
Aquatic Invertebrates, Small Herbivorous and Omnivorous Fish, Small Predatory
Fish, Large Fish, Medium Frogs and Small Frogs.
