　　采用底层拖网方法，以渔获率作为鱼类资源分布的数量指标，进行了南麂列岛岛礁区域2011年4月、8月、11月和2012年3月4个季节的鱼类种类组成、数量分布以及时空变化研究。结果表明：(1)调查海域鱼类有69种，鱼类种数夏季>秋季>冬季>春季；(2)六指马鲅、海鳗、棘头梅童鱼、龙头鱼、赤鼻棱、白姑鱼、鳀、中颌棱、六丝钝尾虎鱼等15种鱼占鱼类总渔获量的鳀89.13%，是调查海域底层拖网的主要捕捞鱼类；(3)不同季节的鱼类渔获量组成相差较大，优势种季节演替现象明显；(4)渔获率的季节变化明显，渔获率夏秋季明显高于冬春季，夏秋季渔获率较高的区域一般在调查海域西北方向的开阔海域。

In this paper, we adopted bottom trawling method and studied the species composition, quantitative distribu-tion, seasonal and spatial trends of island-reef water of Nanji islands fishes according to the four seasons′survey datas in island-reef water of Nanji islands in April, August, November 2011 and March 2012 used catch rates as the quantitative index of fish resources distribution. The result showed:(1) There were 69 species of fishes, and the fish species number is summer (52 species) > autumn (37 species) > winter (26 species) > spring (23 species); (2) The biomass of Polydactylus sextarius, Muraenesox cinereus, Collichthys lucidus, Harpodon nehereus, Thrissa kammakensis, Argyrosomus argentatus, Miichthys miiuy, Thrissa mystax, Chaeturichthys hexanema, Trichiurus haumela, Dasyatis navarrae, Coilia ectenes, Spa-rus latus, Johnius belengerii and Decapterus maruadsi took up 89.13%of the total catch. These 15 species were the bottom trawling main fishing fishes, and the other species of fishes caught less; (3) The seasonal variation on the catch of fishes had a big difference, and the dominant species seasonal succession phenomenon was very obvious;(4) The catch rates had an obvious seasonal change, it was significantly higher in summer and autumn, the higher catch rates area was in the open sea in northwest direction of the survey water in summer and autumn.
