摘　　要：根据1998年5、8、11月和1999年2月在闽东北外海26°00’～28°00’N，120°00’～125°30’E的虾类调查资料，研究分析了该海域高脊管鞭虾（Solenocera alticarinata）数量分布及生物学特征。结果表明：5、8、11和2月调查海域高脊管鞭虾平均密度指数分别为34．7、13．8、4．55和2．89kg·km^-2；其数量分布具有明显的季节性，以5和8月数量为多，11和2月数量较少；分布区域以调查海域的东北部水域为主，以27°00’-28°00’N，122°30’～124°30’E水深80～100m海域数量为多；渔获体长范围为41～129 mm，优势体长组为80～100 mm，占44．7％，雌虾个体明显大于雄性个体，雌虾平均体重为12．0g，雄虾平均体重为8．3g，雌雄性比为1：0．66，生殖盛期为8～11月，不同季节和性别摄食强度没有明显差异。According to the shrimp survey data of four seasonal months in the Northeast Fujian outer-sea （26°00＇ -28°00＇N, 120°00＇ - 125°30＇E）, this paper studied and analyzed the quantitative distribution and biological characteristics of Solenocera alticarinata. The results showed that the average density of its resource in May, August, November and February were 34. 7, 13.8, 4.55 and 2. 89 kg · km^-2, respectively. The quantitative distribution was obvious different from the seasons with May and August being more and November and February being less. The area of high biomass density occurs in the northeast waters of the survey sea and the highest occurs in the waters at depth of 80 to 100 m （27°00＇ -28°00＇N, 122°30＇ -124°30＇E） . The body length varied between 41 and 129 mm, the dominant were between 80 to 100 mm occupying 44. 7%. The female was obviously larger than the male with the sex ratio 1 ： 0. 66, the average body weight was 12. 0 and 8.3 g, respectively. There was no obvious difference for feeding intensity from the seasons or between different sex.
