Abundance and grazing effects of Cyclosalpa bakeri in the subarctic Pacific
Ecological effects of populations of the salp Cyclosalpa bakeri were studied in late summer of 1984, 1987 and 1988 dunng the Subarctic Pacific Ecosystem Research Station P in the northeast Pacific.

| Summary: | Ecological effects of populations of the salp Cyclosalpa bakeri were studied in late summer of 1984, 1987 and 1988 dunng the Subarctic Pacific Ecosystem Research Station P in the northeast Pacific. Salps occurred largely in the top 60 m, with from 76 to 3621 mg C m⁻². Three approaches were taken to estimate the grazing C . bakeri removed from 1.6 to 136.6% of daily primary production and 1.3 to 56.8% diatom stocks in August 1988. On average, feeding rates of the salps predicted ≥5.0 μm from 1.2 to 49.2% of the water column per day in 1984 and 1988. Although N appears negligible, production of fecal C and N can be high, as much as 875 mg C N m⁻² d⁻¹ at the highest population density sampled Although the salps probably do grazing impact on the small cells (≤5.0 μm) which are responsible for most of the they may be important in controlling populations of diatoms which typically occur in Station P. |
