| dietary preference and digestive enzyme activities as indicators of trophic resource utilization by six species of crab. | the digestive physiology and stomach contents of six crab species from a variety of habitats were investigated to provide an indication of their digestive capability and dietary preferences. stomach contents varied between species, but the key enzymes present were generally consistent with the types of dietary material being ingested. nectocarcinus integrifons (red rock crab) consumed large quantities of seagrass and had high cellulase activity (0.02+/-0.004 units mg-1) to digest the constituent ... | 2005 | 15713811 |
