Underwater Trawl Net Debris Investigation海底拖網廢棄物調查

The Daxi Fishing Harbor in Yilan is located in Daxi Village, Toucheng Township, 10 kilometers south of Wushih Harbor. Due to its proximity to the Guishan Island fishery, it is rich in fishery resources. However, the increasing problem of marine debris has severely impacted the marine ecosystem. Trawling has become heavily stigmatized, leading to a decline in the fishermen's sense of pride. In recent years, the issue of marine debris has gradually worsened, and over time, it has had a significant negative impact on the marine ecosystem and fisheries at the ocean's lower levels. In recent years, the amount of underwater debris has been increasing. When fishermen engage in bottom trawling, they often haul up more trash than fish. Additionally, many fishermen lack awareness of environmental education. The general lack of marine knowledge has led to insufficient understanding of the challenges facing the ocean, making it difficult to protect the marine environment more effectively.

After conducting this project, it was discovered that agricultural waste constitutes a significant portion of the underwater debris around Guishan Island. This highlights the need for future efforts to address the issue of agricultural waste and raise awareness. As a result, the project collaborated with local captains from the Daxi Fishing Harbor in Yilan to carry out a survey of underwater debris in Yilan's waters, forming a team called ‘Marine Waste Warriors.’ The team empowers and recruits willing fishing boats to help collect and investigate underwater debris, specifically focusing on resource surveys of marine debris in the offshore areas of Yilan.

Additionally, the project organized workshops for training volunteers in underwater agricultural waste investigation and environmental education seminars. These events aimed to promote awareness of marine debris concepts and train local residents to become volunteer investigators for marine waste, helping the project conduct further surveys. The team also participated in recruitment briefings for the environmental fleets in Toucheng and Su'ao, where they shared the findings of the Yilan underwater debris investigation.

Furthermore, the project integrated marine debris and environmental education into general education courses at schools, helping students understand the composition of marine waste and encouraging them to reflect on and propose ideas for the reuse of underwater debris.

This project has conducted three environmental education courses and continues to recruit members for the ‘‘ Marine Waste Warriors’’ team. So far, two fishermen have joined the team, collaborating with trawling boats from Daxi Fishing Harbor to carry out investigations on underwater debris, specifically focusing on the distribution of marine waste around Guishan Island. Through coastal resource assessments, the project aids in trawl net underwater debris investigations and implements related educational training programs for fishermen.

A team called ‘‘Chasing Underwater Agricultural Waste’’ was also formed by students from the school and local residents. This team was selected for the Ocean Conservation Administration’s Marine Citizen Scientist Program and has partnered with trawling boats from Daxi Fishing Harbor to investigate the distribution of underwater debris around Guishan Island. They have completed multiple trawl net debris surveys and are working to cultivate the long-term ability of local residents to deeply engage in the investigation and removal of marine waste in Yilan.

Sustainable Impact:

  2. Total weight of agricultural waste: 6,225 grams
  3. Total wet weight of agricultural nets: 1,258 grams
  4. Total length of irrigation tubes: 5,140 grams

宜蘭大溪漁港位於頭城鎮大溪里，南距烏石港10公里，因鄰近龜山島漁場，漁業資源豐富，但隨著海洋垃圾問題日益增加，也嚴重影響海洋生態，拖網漁業受嚴重污名化，漁民榮譽感日漸低落。近年海洋垃圾問題逐漸嚴重，在長期累積之下，對海洋底層生態系及漁業造成顯著負面影響。近幾年海底廢棄物日益增加，當漁民在進行底拖漁業時，打撈的垃圾常比魚多，且普遍漁民較缺乏環境教育之觀念。然而，缺乏海洋知識使人們對於海洋所面臨之問題認知不足，難以更有效的保護海洋環境。

經本計畫調查後發現，在龜山島周遭的海底垃圾中，農業廢棄物佔有相當高的比例，也顯示後續更需進行農業廢棄物問題的解決及意識推廣。因此，本計畫與宜蘭大溪漁港當地船長一同進行宜蘭海域海底廢棄物調查活動，組成海廢戰塑團隊，培力並召集有意願的漁船協助蒐集與調查海底垃圾，針對宜蘭外海之海底垃圾進行資源調查。同時辦理海底農廢調查志工培訓工作坊與環境教育分享會，進行海洋廢棄物概念宣導，培訓在地居民成為海廢調查志工，協助計畫執行海廢調查。也參與頭城、蘇澳環保艦隊招募說明會，並於說明會中分享宜蘭海底廢棄物調查之成果；將海底廢棄物支環境教育觀念結合校內通識課程，使學生了解海廢之組成，並進行海底廢棄物再利用之反思與發想。

本計畫已辦理三場環境教育課程並持續招募海廢戰塑團隊，已有兩名漁民加入海廢戰塑團隊，與大溪漁港拖網船合作進行海廢調查，持續調查龜山島周遭海底廢棄物分佈。透過沿海資源盤點，協助進行拖網海底廢棄物調查，針對漁民推行教育訓練相關規劃。本校學生也與在地居民組成團隊「海底農廢追追追」獲選海保署海洋公民科學家計畫與大溪漁港拖網漁船合作，調查龜山島周遭海底廢棄物分佈，完成多次拖網海廢調查，並培養在地居民長期深耕宜蘭海廢調查、清除之能力。
