The Impediments on the Recovery of Grass Prawn Aquaculture Industry in Taiwan

台灣的養殖草蝦曾經有過一段輝煌歷史，然自1988年爆發草蝦病變後，即陷入長期低迷，迄今仍未見任何復甦跡象。為瞭解情況，本研究利用1986-1999年間之31戶養蝦戶之追蹤資料估算產業之總要素生產力(Total factor productivity, TFP)。研究結果顯示，自1989年起歷年之TFP值均明顯低於1988年以前之水準，此意味著不論是生產或管理技術都受到1988年蝦病嚴重衝擊。1988年以後，儘管政府投入不少研究獎勵與補助計畫從事相關研究，然而草蝦養殖產業仍未見明顯起色。本研究認為阻礙草蝦養殖產業復甦之主要原因有二，一為漁業主管機關之研究獎勵系統並無法有效解決這些問題，使此事件重創台灣草蝦產業並造成長遠之傷害；另一則是許多養蝦業者缺乏專業管理能力所致。因此，本研究認為草蝦產業要能再創另一春天，必須重新檢討政策和增強研發能力與管理制度。

The grass prawn aquaculture industry in Taiwan had experienced production boom in the past which lasted for two decades. The industry collapsed and hardly recovered due to the outbreaks of shrimp viral disease since 1988. To get an inside look on how worse the situation was, this research estimated the total factor productivity (TFP) for the industry from 1986 to 1999 using 31 fishermen's panel data. Our findings showed that all TFPs have been dimming since 1989, which means that there was no better technology nor managerial skill that effectively solved the 1988 shrimp collapse. The sad truth confirms that after millions of research grants for academic and research institutes and support projects for aquafarmers, the grass prawn aquaculture industry was not revived until the present time. Thus, this research is questioning the major factors that hindered the recovery of the industry. The impediment of relief efforts comes from two places. First, the ineffective research grant system from the administration turned the catastrophe to a permanent loss for the grass prawn aquaculture industry. Second is the irresponsible field management by numerous myopic profit-oriented aquafarmers. In the end, the grass prawn aquaculture industry needs both a total start-up from the research's development and responsible administrative institutions for successful revival.
