Abstract:A laboratory study of energy transformations by the pelagic decapod
crustacean Lucifer chacei was made. Three combined stages were cultured and
studied: the protozoea-zoea stages, the combined early and late schizopod stages,
and the combined adult stages. Growth rates, dry weight, ash content, and calorific
values were determined for each. Number of calories per hour ingested, assimilated,
and respired were also determined for each of the combined stages. An
energy flow diagram was constructed from the data.
Growth from egg to adult took slightly more than 3 weeks. Protozoea-zoea and
schizopod stages assimilated 10.1 percent and 10.4 percent of ingested Dunaliella
tertiolecta. Adults assimilated 7.7 percent of ingested Dunaliella tertiolecta and
approximately 22 percent of ingested Artemia salina nauplii. The data indicate that
a change from herbivorous larvae to omnivorous adults may have to occur in the
natural environment because the older stages cannot obtain enough energy for
growth from phytoplankton alone. When data for all stages were combined, gross
growth efficiency and net growth efficiency for Lucifer were approximately 10 percent
and 81 percent, respectively.
