Information
Ecological parameter: feeding typeParameter group: life & body related parameters
Explanation:
This parameter indicates the feeding preference of a species. Ten categories are defined according to Moog (1995).

Classification system: 10 point assignment system
Abbreviations:
| Category name | Abbreviation | Explanation |
|---|---|---|
| grazers/scrapers | gra | feed on endolithic and epilithic algal tissues, biofilm, partially POM, partially tissues of living plants |
| miners | min | feed on leaves of aquatic plants, algae and cells of aquatic plants |
| xylophagous taxa | xyl | feed on woody debris |
| shredders | shr | feed on fallen leaves, plant tissue, CPOM |
| gatherers/collectors | gat | feed on sedimented FPOM |
| active filter feeders | aff | feed on suspended FPOM, CPOM; micro prey is whirled; food is actively filtered from the water column |
| passive filter feeders | pff | feed on suspended FPOM, CPOM, prey; food is filtered from running water, e.g., by nets or specialised mouthparts |
| predators | pre | feed on prey |
| parasites | par | feed on host |
| other feeding types | oth | use other food sources not meeting the above categories |
