摘要：

Daily food intakes, optimal feeding regimes and food concentrations for laboratory reared Paralithodes camtschaticus (Tilesius, 1815) larvae were investigated. Artemia nauplii hatched at standard conditions were used as food. Daily food intakes of zoeae I-IV at 7-8 degrees C comprised 11.3, 22.4, 33.2, and 41.8 nauplii individuals (ind)(-1) day(-1), respectively, taking into account that wet weight of Artemia nauplii used for the experiments constituted 0.026 mg, dry weight 0.0042 mg. Optimal initial Artemia nauplii concentrations for feeding zoeae I-IV was determined as 400-600, 600-800, 800-1000 and 1000-1200 nauplii L-1 respectively. Recommendations on using Artemia nauplii as food for red king crab larvae were outlined on the basis of experimental results. Growth, development and survival rates of zoeae I-IV reared in recycling water system at 7-8 degrees C and fed Artemia nauplii according to these recommendations were described.
