中文摘要 | 為瞭解東沙島北部小區域陸坡漁場之魚種組成及社群結構,1995年4 月17至18日間,於21o00'N?21o40'N,116o20'E?117o00'E,水深 280 至361 公 尺海域,實施6網次底拖網漁撈試驗,漁獲種類46種。其中,魚類之線性生物 量 (Linear biomass) 大於20.0,且於兩測站或兩測站以上同時出現者,計有主 要魚種11種,約佔總漁獲量的69.4%。捕獲的 3種蝦類約佔總漁獲量的5.37%。 調查結果:(1)各測站之夏農•魏能 (Shannon-Wiener) 歧異度指數與各測站無顯 著的差異。(2)以社群分析調查各測站結果,主要魚種組成大致可區分為2個群 社。依魚種別之對數線性生物量亦可將所調查測站區分為2個群社。 |
英文摘要 | To understand the characteristics of community of demersal fishes in north Tung-Sha Tao, 6 bottom trawl operations were conducted along a transect at depths of 280-361 meters during 17-18 April 1995. A total of 11 major fish species occupying 69.4% of the total collected species were recorded. Three prawn species, Heterocarpus woodmasoni, Haliporoides sibogae , and Plesionika spp. were found. The species that was found at duplicated stations and with a total linear biomass greater than 20.0 were selected for the cluster analysis. The relationship between the values of Shannon-Wiener's index and the sampling stations had no significant difference (p>0.05). Using the Unweighted Pair Group Method Arithmetic Average (UPGMA) and the Bray-Curtis dissimilarity values, the 11 fish species were classified into 2 groups and 6 trawls were grouped into 2 clusters respectively. |
