%X Fed on cells of Tetraselmis subcordiformis with high nitrogen content(HN,molar C/N=8.5),low nitrogen content(LN,C/N=12.7) and with short-term addition of nitrogen after culture in f/2 medium without N(AN,C/N=9.6),the Growth,development and ingestion of Pseudodiaptomus annandalei were investigated.With the increase of C/N of algal cells,growth rate of P.annandalei decreased from(0.067±0.001) to(0.056±0.001) d?1.Nauplii entered into copedites or maturation on Day 5 or 18 after birth under HN condition.Under LN condition,they developed into copedites on Day 8.N contents of nauplii,copedites and adults of P.annandalei decreased with the increase of C/N of algal cells.So did the survivorship.P.annandalei of all three life stages under HN or AN conditions had higher ingestion rates in terms of N (0.53—0.95)×10?4mgN/(ind.h)] than those under LN condition (0.32—0.6)×10?4mgN/(ind.h)].However,only adults under HN had higher C ingestion rate than their counterparts under LN condition (8.11±1.21)×10?4 vs.(7.54±0.35)mgC/(ind.h)].N deficiency significantly suppressed the growth,development and ingestion rate in P.annandalei.The short-term addition of N partly reversed the suppression by LN.
