中文摘要：2010年8月至2011年5月,通过一周年的连续季节性独立站点底拖网调查进行长肋日月贝采样(794个),测定生物学性状、统计渔获量并进行资源评估,研究其形态性状与质量的关系、生长发育的变化以及资源分布情况。结果表明,4个形态性状对体质量和闭壳肌质量的偏相关影响依次为壳长>壳宽>壳高>铰合线长,其中壳长、壳宽和壳高是决定质量性状的主要因素,软体质量和闭壳肌质量分别占总体质量、软体质量的约50%。生长研究表明,夏季主要是贝壳的生长,春季主要是软体部分的生长。长肋日月贝为雌雄同体,在一年中多次产卵。该资源于北部湾主要分布在20~50 m水深的20°15′~21°15′N、108°~109°′E海域,底质以泥、泥沙和沙泥为主,在空间上的分布有明显的规律,由南向北呈递增趋势,由西向东先增后减。资源密度呈现明显的季节变化,以夏季为最高,春季至冬季的平均资源密度依次为8.72、13.93、9.82和5.90 kg/km2。对表层水温、盐度和浮游生物密度等环境因子的遥感数据分析表明,表层水温对资源分布的影响最大,相关系数达0.972,与其余两种参数不呈线性相关。

外文摘要：Through the commercial fishing independent trawlers catch sampling, a total of 794 individuals of Asian moon scallop, Arnusium pleuronectes were collected quarterly from August 2010 to May 2011 in the Beibu Gulf, South China Sea. By biological measurement and resource statistics, the relationship of modality parameters and weight parameters, and the growth and the resource distribution were studied. Results showed that the partial correlation effects of four modality parameters on body weights and ad- ductor weights were as follows in sequence： shell lengths 〉 shell widths 〉 shell heights 〉 hinge ling lengths. Shell lengths, shell widths and shell heights are the most important parameters. Moreover, the mollusk and adductor muscle accounted for almost half of the total body weight and mollusk weight re- spectively. In summer, the main growth was the shell. In spring, the mainly growth was the mollusk part. The resources are main distributed in the areas of 20~15＇N-21~15~N, 108^-109~＇E, with the water depth ranging from 20 m to 50m and the bottom covered with mud and sand. The spatial distribution showed distinct regularity character. It progressively increased from the south to the north by the latitude, and in- creased firstly and then decreases from west to east by the longitude. Seasonal variations were also recorded with the peak in summer and the value from spring to winter was 8.72, 13.93, 9.82 and 5.90 kg/km2 respectively. Statistics demonstrated that sea surface temperature was the most important environmental factor and has a positive correlation with the average resources density （r=0.972）, while salinity and plankton did not show linear correlations.
