鮆科仔稚魚漁業是臺灣枋寮沿海最重要的漁業之一,其漁獲混雜有5%左右之經濟魚種,其漁獲結果對臺灣沿近海漁業生態系之影響頗受關注,本報告利用聲探系統配合漁獲試驗、海洋斷面觀測、生物測定、長年漁獲統計、定點水溫長期觀測、河川流量等究明其魚羣分布實態與漁場學特性。其結果如下:(1)枋寮沿海以日本鮆(Engraulius japonica)為主,銀带鰾屬(Stolephorus zollingeri and Stolephorus heterolobus)為輔,銀带鰶之適溫適鹽範圍較日本鮆為廣,其適滲透壓範圍分别為25.75-25.9及25.58-25.76,該滲透壓之縱向及横向分布範圍卽為漁場分布之界限。(2)鮆科仔稚魚以小羣聚於河川水與海水之交會處附近,其分布之範圍以河川水之流軸及外洋高鹽海水為界。(3)臺灣冬天河川流量低,剛好在其適滲透壓範圍,故為主漁期,低溫之時日以漁獲日本鮆為主,高溫之時日則以銀带鰶為主,其長年漁獲組成亦有變動。南方振動强烈(E1-Nino現象),臺灣有暖冬現象,此時以漁獲銀带鰾為主,反之,冷冬時(南方振動弱)則以漁獲日本鮆為主。
The larval anchovy fishery is one of the most important coastal fisheriesin Taiwan.The species caught mainly belong to the Family Engraulidae.Inthis paper,the factual distribution conditions of larval anchovy from thecoastal waters of Fang-Liao by means of hydroacoustic survey was studied.Serial observations on temperature and salinity were simultaneously recorded.The results are as follow:(1)The species caught was mainly composed of Engraulis japonica andpartly Stolephorus zollingeri and Stolephorus heterolobus.The optimal ranges oftemperature and salinity for Stolephorus were wider than those for Engraulisjaponica,while the optimal osmotic pressure ranges of the above two generawere 25.75-25.9 and 25.58-25.76atm,respectively.(2)Several larval anchovy schools may form a unique fish shoal alongtheir optimal osmotic pressure regions.The margin of fish shoal wasbordered by the flow axis of river discharge with low osmotic pressure andthat of offshore current with high osmotic pressure.(3)The composition of daily catch fluctuated with sea surface temperature(SST)and so did the composition of annual catch.When the southernoscillation index was strongly negative(i.e.E1-Nino)and the SST in winterwas anomalously warm,the major composition of caught species belonged toStolephorus.On the other hand,when the environmental condition wasresversal,the main catch became Engraulis japonica.
