We monitored secondary production individual reproductive characteristics (l e reproductive penodicity female size fecundity, reproductive output) and oocyte standing crop dunng an oscillation cycle of a laboratory population of the opportunistic polychaete Capltella capitata type1 Biomass oscillation resulted from changes In the amount of food available per unit standlng blomass of C capitata During populatlon d e c h e reproduction and secondary producbon were reduced this conflrms that the population cycle was driven by food avallabllity Compansons of actual supplied ratlon vs theoretical estimate maintenance ratlon needed to support the populatlon suggested that the population was overshooting ~ t s carrylng capacity However maxlmal populatlon biomass and denslty did not decline sharpely and were sustained over an 8 w k penod Decreases in production and reproduction rates preceding population decline are indicative of metabolic regulabon to adjust energetic requirements to available resources This observahon suggests that the population would not overshoot its carrying capacity When density was low, dally food ratlon exceeded the whole community requirements and food accumulated in the tray Unhl used, such bulld-up increases the amount of food avalable to C capitata, resulhng in an oscillating (actual) carrylng capacity above the static (theorehcal) carrylng capaclty calculated relatlve to the daily food-ration Our results suggest that the population did overshoot thls theoretical carrylng capacity but not the actual canylng capacity
