Laboratory and field estimates of the rate of faecal pellet production by Antarctic krill, Euphausia superba

The time course of faecal pellet production (egestion) was monitored in January 1985 for a population of Antarctic krill, Euphausia superba , maintained in flowing seawater aquaria at Palmer Station, Antarctica. The rates of faecal egestion observed in this study indicate that the flux of faecal pel...

Zusammenfassung:	The time course of faecal pellet production (egestion) was monitored in January 1985 for a population of Antarctic krill, Euphausia superba , maintained in flowing seawater aquaria at Palmer Station, Antarctica. The rates of faecal egestion observed in this study indicate that the flux of faecal pellets from krill is substantial. They imply an energy intake in E. superba of 17 to 28% body weight per day.
