Core Viewpoint - The local government has implemented a ban on beachcombing activities in Beihai Xia Village to protect the ecological environment and allow the coastal ecosystem to recover, following years of overexploitation and environmental degradation caused by tourism and illegal fishing practices [10][12]. Group 1: Environmental Impact - The use of destructive fishing gear, such as fine-meshed nylon nets, has led to significant ecological damage, particularly affecting the population of horseshoe crabs, a nationally protected species [3][5]. - The increase in beachcombing tourism has resulted in a decline in marine biodiversity, with many small marine organisms being collected indiscriminately by tourists, which disrupts the food chain for migratory birds [5][6]. - The activities of tourists, including digging and driving vehicles on the beach, have created physical barriers that hinder the movement of juvenile horseshoe crabs and other marine life, leading to increased mortality rates [3][5]. Group 2: Economic and Social Dynamics - Initially, local villagers engaged in beachcombing tourism cooperatively, setting a unified price of 38 yuan, which fostered a sense of community and ecological responsibility [6][8]. - The influx of external businesses has disrupted this cooperative model, leading to price wars and a focus on profit over ecological sustainability, resulting in a decline in local community cohesion [8][10]. - The local government's ban aims to restore the ecological balance and provide a respite for the beach ecosystem, with hopes for improved management practices in the future [10][12].

Core Viewpoint - The article discusses the dual nature of "catching the tide" tourism, highlighting both its economic benefits and the ecological risks associated with unsustainable practices [1][2]. Group 1: Economic Impact - "Catching the tide" has evolved into a tourism project, integrating various business models such as "catching the tide + research" and "catching the tide + homestays," which have stimulated the cultural and tourism economy [1]. - The tourism model serves as a "low-cost breakthrough" for coastal areas, attracting visitors without significant investment, relying solely on natural resources [1]. Group 2: Ecological Concerns - Tourists using destructive tools like high-pressure water guns and rakes are damaging habitats of bottom-dwelling species, while activities in rocky areas harm coral and seaweed beds, undermining natural coastal defenses [1]. - The article emphasizes that such practices violate the principles of marine biodiversity protection and lead to ecological degradation [1]. Group 3: Solutions and Recommendations - A collaborative mechanism for protection, development, and sharing should be established, including zoning for "catching the tide" areas with designated protection and limited activity zones [2]. - The implementation of service standards, such as requiring travel agencies to provide ecological guides and promoting biodegradable tools, is recommended to achieve "no trace" catching [2]. - Engaging participants in ecological protection through incentive mechanisms, like "trash for souvenirs," and integrating fishermen into the tourism industry can create a positive cycle of ecological preservation and economic growth [2].

Core Viewpoint - The traditional practice of "catching the sea" has evolved into a popular tourist activity, leading to significant ecological challenges as tourists engage in destructive methods that threaten marine biodiversity [1][3][12]. Group 1: Tourism Development - The beach at Tangjiawan has become a social media hotspot, attracting over ten thousand visitors daily during the summer, transforming the traditional fishing activity into a leisure pursuit [3][8]. - The rise of "catching the sea" as a new cultural tourism model has stimulated local service industries, but it has also led to increased pressure on marine ecosystems [3][19]. Group 2: Ecological Impact - The seagrass bed at Tangjiawan, home to the endangered Halophila beccarii, has seen a drastic reduction in area, with only 10% of its original size remaining since the influx of tourists began in 2020 [8][7]. - Destructive practices by uninformed tourists, such as digging and using salt, have resulted in the removal of vital seagrass, which plays a crucial role in marine biodiversity and food chains [5][8]. Group 3: Conservation Efforts - Local authorities and researchers are advocating for the establishment of protected areas and have begun implementing educational campaigns to inform tourists about sustainable practices [10][19]. - Volunteer teams have been organized to guide tourists and set up warning signs to prevent harmful activities in sensitive ecological zones [10][18]. Group 4: Regulatory Challenges - Some commercial operators are engaging in illegal practices, such as "deep catching," which involves trapping marine life in nets, posing a severe threat to local ecosystems and endangered species like the Chinese horseshoe crab [12][14]. - The unregulated nature of tourism in areas like Beihai and Beigang Island has raised concerns about the sustainability of marine resources and the health of local ecosystems [14][16]. Group 5: Future Directions - Experts suggest that a balanced approach to "catching the sea" should be adopted, focusing on ecological sustainability while allowing for tourism development [19][21]. - The concept of "ecological catching" emphasizes the need for proper resource assessment and management to ensure that tourism does not compromise marine biodiversity [21].
