Digestive carbohydrase activities in individual marine copepods


Marine Biology Letters 3(4-5): 211-222
Digestive carbohydrase activities in individual marine copepods
A digestive enzyme assay is presented that is applicable to small sample sizes, on the order of individual Calanus pacificus Brodsky. Responses to time and enzyme concentration were linear under the specified conditions. Assays of individual copepods revealed a high coefficient of variation for all 3 enzymes [laminarinase, cellobiase and maltase], indicating the potential for large variability in field samples. Of the variability, 90-95% was attributable to differences among animals. The digestive carbohydrases appear to be responding collectively, but it remains for controlled experiments to determine the extent of this relationship.
