Abstract
This study aimed to describe the impact of diet on specific dynamic action
(SDA) in Clearnose Skates (Rostroraja eglanteria). Metabolic rates of mature female
Clearnose Skates (n=2) were calculated before and after being fed anchovies and
shrimp. Metabolic rates were measured using static respirometry. Skates had an
increase of up to 1.68x pre-feeding MO2 when eating anchovy, and an increase of up
to 1.31x pre-feeding MO2 when eating shrimp. Meal size was also found to increase
the duration and peak of the SDA effect. Minimizing the amount of energy occupied
by SDA makes feeding more efficient and provides more available energy for
Clearnose Skates.
