中文摘要 | 本文研究淡水河口域仔稚魚相及其與環境因子之關係。從1988年3月及1989年5月共進行15次採進。共採得38,501尾標本,分屬於52科90種。優勢科鮆科(35.9%)、鯡科(24.8%)、鯔科(17.9%)、鑽嘴魚科(10.4%)和沙 科(2.8%),其他魚種僅佔8.2%。24小時連續採進發現仔稚魚之出現高峰與最高漲之時間一致。而整年度的採集結果來看,第三站(最靠近出海口)之鹽分濃度及採得之仔稚魚總數、密度均是三站中最高者。潮汐可能是影響淡水河口域仔稚魚出現之因子之一。 |
英文摘要 | Occurrence of fish larvae and juveniles and their relationships to the environmental factors in Tan-Shui estuary were studied. Fifteen samplings were taken at three stations from March 1988 to may 1989. A total of 38,501 larval fishes was collected during the study period. They included from larval to juvenile stages, belonging to 52 fanukues abd 90 species. Dominant families were Engraulidae (35.9%), Clupeidae (24.8%), Mugilidae (17.9%), Gerreidae (10.4%), and Sillaginidae (2.8%), whereas the rest of species were less than 8.2%. The peaks of occurrence of fish larvae and juveniles coincided with the timing of the high tide in 24-h serial samplings. No matter when the sampings were performed, the larval density , total catch of the year and the salinity at station 3 were the hightest among three stations. It is suggested that the tide perhaps was one of the important factors affecting the occurrence of fish larvae and juveniles kin Tan-Shui estuary. |
