Abstract
A study was undertaken to determine the energy utilized by
Sesarma in feeding upon Spartina over lunar-monthly periods.
Amounts of Spartina ingested and assimilated, in terms of grams
dry weight, were found for three groups of crabs. These studies
indicate a possible relationship between the quantity (i.e. grams
dry weight) and/or quanity (i.e. associated with maturity) of
Spartina available to the crabs and the amounts ingested and
assimilated. These data, in addition to data from respiration
measurements, were combined with information from the literature
to construct energy budgets, in terms of caloric values, for the
three groups.
