鹿港美食螻蛄蝦 Upogrbia edulis Ngoc-Ho and Chen, 1992,俗 稱陸港蝦猴是彰化地區的傳統佳餚.傳統漁民在業餘之際,仔在灘地上挖掘螻蛄蝦以貼捕家用,百年來該資源得以永續利用.但是近五年來有十二組漁民更新採集技術,改以水灌法採集,使得螻蛄蝦生產量大幅提高.雖水灌法具有豐厚利潤,但因採集面積過大,對棲地也有相當程度的破壞.本文於1997年4月至12月,選擇彰化縣伸港灘地,針對水灌式,手挖式採集法對於螻蛄蝦族群的影響程度進行調查.透過參與式觀查法了解螻蛄蝦產業的產銷過程,最後整合伸港區的環境資源,提出經營管理策略.本研究先標定手挖式,水灌式採集業者在個年份的區位,再進行螻蛄蝦密度及生物量的調查,結果如下:傳統手挖採集區內的密度及生物量,在採集後第4年恢復率均可達90%.水灌法在的密度約恢復70%,生物量只恢復50%.螻蛄蝦會從採集區邊緣向採集區內部拓殖.本研究提出3點螻蛄蝦的經營管理策略:1.為了使螻蛄蝦的再生率和收獲量可以平衡,建議彰濱由遊樂區應維持灘地現狀,並規範採集行為與技術,包括限制採集人數,頻度,採集器具在灘地上的行走路徑,應避免大面積連續採集的方式.在水灌式採集區使用底播增殖與棲地復育的方法,增加螻蛄蝦的族群數.2.為了保護螻蛄蝦資源,在伸港區的水鳥保護區內,依照野動法之規範,嚴禁螻蛄蝦的採集.3.垃圾掩埋場預訂地的螻蛄蝦族群約佔伸港區總族群的40%,建議終止該計畫以保存螻蛄蝦棲地.入若該計劃持續進行,應加格隔離設施與環境監測.
The Lu-Kang mud shrimp Upogebia edulis is one of the famous seafood at coastal area of central Taiwan. traditionally, the fishermen dug the mud shrimps by spade.Since 1993, twelve groups of fishermen introduced the new hydraulic dredging methods to increase fisherr output.The new method substantially increases production and profit, but it may have impact on the shrimp population. Thestructure of fishing ground maybe disturbed too much so thaat the recovery of the shrimp populationis retarded. For this research, a field survey was conducted at Sheng-Kang intertidal area from April to December 1997. The auther investigated the fishing methods,amount of the production and the market price.In the begening, the auther labeled the last four years of mud shrimp that were harvesedby three fishing methods. This methods include traditional digging, the ocntiguous and non-contiguous hydraulic dredging method.Afterwards, the authet estimated the density and biobass of mud shrimp and compared the recovery rate to the population of the non-harvested neighboring area. The result shows that four years after diggind , the recovery rate of populationdensity and biomass of mud shrimp at traditionally dug aeras is about 90%. Therecovery rate of population density at the two hydraulic dredging areas was about 70% and the recovery rate of biomass was about 50%. The research also implicates that the recruited mud shrimpat the harvest area were recolonized from neighboring undredged areas. By integrating the research finding, three ,management and conservation strategies for sustainable use of the mud shrimp resources are discussed: 1. The new methods used to mud shrimp should be regulated, including the limits on the number of fishermen, fishing frequency , fishing ground and harvest routes. The restoration of the habitat, and population accruement of mud shrimp. 2. The mud shrimp in TaTu Wildlife preserve shouldbe protected fromharvesting to serve as a source for recolonization. 3. The garbage dump sitecontain 40% approximately suggest the plan be modifued in order to betterpropect the mud shrimp.Keywords: mud shrimp, hydraulic dredging method, conservation strategies.-1 -aThe Study of the Fishery Impact and Conservation Stratery of Mud-Shrimp at Chung-Hua Coastal Area
