Spot Prawn

Biochemical composition of body segments and physiological condition of the spot prawn (Pandalus platyceros) were determined during 84 d of starvation and 21 d of subsequent feeding. Maximum molting frequency, 1.79%∙d−1, occurred from day 22 to 43 and mortalities peaked at 0.81%∙d−1 on resumption of feeding. Ratios of wet weight of hepatopancreas to abdomen or whole body decreased on starvation and increased on feeding, and so provided an index of physiological condition. Uptake of moisture and chlorides with loss of other halides in prawn tissue resulted from starvation. Resting oxygen consumption rate declined by 50% after 40 d of starvation. Lipid in the hepatopancreas increased during early inanition to become the major energy source. Lipid contributed 73.1%, protein 20.6%, and carbohydrate 6.3% of total metabolized reserves. Hepatopancreas, carcass, and abdominal muscle generated 49.1, 33.4, and 17.5% of energy utilized. On subsequent feeding, lipid, carbohydrate, and protein accounted for 73.8, 20.1, and 6.1% of total caloric uptake with energy assimilation by body sections similar to depletion values. Spot prawn have sufficient reserves to remain in good commercial condition for 40 d without food.

This chapter presents a third example application of state- and prediction-based theory (SPT), again involving a behavior originally modeled via dynamic state variable modeling (DSVM). This example also addresses animal foraging, this time a choice of foraging activity. In this case, physiology has more important and interesting effects on behavior: the model animal, like many herbivores, can consume food relatively rapidly but does not assimilate its energy until the food's rather slow passage through a long gut. This leads to uncoupling of foraging behavior and energy assimilation on short time scales. The example is based directly on the DSVM analysis by Santini et al. of foraging behavior in the limpet Cella grata, which feeds by scraping rocks in the intertidal zone.
