近日，在甘肃省定西市安定区鲁家沟镇的凤城湖养殖基地，6万只人工养殖的中华绒螯蟹蟹黄正肥，收 获时节随之而至。 作为当地特色养殖项目，鲁家沟镇依托"引洮工程"水资源和冷凉气候条件，采用优质蟹苗繁育，以大 豆、玉米等天然饲料进行科学饲养，养殖的大闸蟹达到高品质标准。 在特色养殖业助力乡村振兴的同时，定西市同步推进生态建设，绘就绿色发展新图景。 初冬时节，当地抢抓秋冬季苗木扎根的黄金窗口期，动员干部群众、志愿者及林草专业团队进行植树造 林活动。 自2021年定西市开展大规模国土绿化行动，即"绿满陇中"行动实施以来，当地以黄河流域生态保护和高 质量发展为核心，统筹推进"三北"工程、水土流失综合治理等重点项目，坚持"适地适树"原则，优选侧 柏、油松等耐旱固碳树种，构建多层次生态防护体系。 近年来，湖南省常德市鼎城区因地制宜，大力推广秸秆还田、离田收储模式，探索农业废弃物资源化利 用新路径。当地种粮大户李建红承包了200亩水稻，今年，他在自家的旋耕机后面加装了埋茬设备，直 接将秸秆粉碎还田。 综合新华社记者报道 湖南省双峰县杏子铺镇双源村到江口村的溪口路提质升级后，成为带动乡村产业发展，带火乡村旅游的 致富路、产业路。 ...

Group 1 - The innovative "seafood river fresh land farming" model in Yutian County, Xinjiang, allows local residents to consume seafood and river products cultivated in saline-alkali land [1] - The aquaculture base in Yutian County is located in the core area of a 100,000-acre saline-alkali land management project and is the largest aquatic production base in the Hotan region, producing over 800 tons of four major fish species, 15 tons of South American white shrimp, and 10 tons of Chinese mitten crabs annually through technical cooperation with research institutions [3] Group 2 - The peak season for cicada harvesting is currently underway in Anqiu City, Shandong, where thousands of cicadas are served daily in local restaurants, primarily sourced from artificial breeding [4] - In a cicada breeding base in Huiqu Town, Anqiu City, cicadas emerge from the soil at night and climb trees, showcasing a unique breeding environment [6] - The harvested cicadas are cleaned, frozen, and sold at approximately one yuan each to nearby restaurants or shipped to buyers outside the region, with the cicada farming integrated with vegetable cultivation to achieve dual income [8]

Core Viewpoint - The innovative "seafood land farming" model in Yutian County, Xinjiang, transforms previously barren land into productive aquaculture, providing local residents with access to seafood and creating a new path for ecological restoration and income generation [1][13]. Group 1: Aquaculture Development - The aquaculture base in Yutian County spans 1,240 acres and includes 43 ponds, cultivating over ten species such as grass carp, South American white shrimp, and Chinese mitten crabs, with sales extending to surrounding counties and regions like Tibet and Qinghai [3][5]. - The base is the largest aquatic production facility in the Hotan region, producing over 800 tons of four major fish species, 15 tons of South American white shrimp, and 10 tons of Chinese mitten crabs annually, making "desert seafood" a sought-after market commodity [5]. Group 2: Challenges and Solutions - A significant challenge in the aquaculture development was the high mortality rate of seedlings, primarily due to long transportation times from the eastern coastal regions and the stark differences in water quality between coastal and local saline-alkali environments [7]. - To address this, a 700 square meter greenhouse was constructed to create a specialized "acclimatization workshop" for seedlings, featuring large water storage and breeding tanks to improve survival rates [9]. Group 3: Economic Impact - The development of the aquaculture industry has not only satisfied local culinary desires but also provided new income opportunities for residents, transforming former farmers into "aquaculture technicians" and improving their livelihoods [11].

Core Viewpoint - The article highlights the successful completion of marine species release activities in a province, emphasizing the ecological and economic benefits of fishery resource enhancement through the release of various species of fish and shellfish [1][2] Group 1: Marine Resource Enhancement - The province has released a total of 3.3 billion juvenile fish and shellfish, including Chinese shrimp, three-spot crab, and brown sole, exceeding the central government's release plan [1] - The province has been conducting marine resource enhancement activities for 40 years, focusing on biodiversity protection, ecological environment improvement, and increasing fishermen's income [1][2] Group 2: Scientific and Technical Oversight - The provincial agricultural and rural development service center has developed detailed project implementation plans and coordinated various departments to ensure the scientific and standardized process of resource enhancement [2] - Industry experts provided technical guidance throughout the entire process, ensuring quality control in procurement, seedling quality, and acceptance before release into the sea [2] Group 3: Economic and Ecological Benefits - The release of suitable seedlings is expected to increase biomass in water bodies, optimize biological community structure, and promote the sustainable use of aquatic resources [2] - The investment-to-output ratio for fishery resource enhancement has been evaluated to exceed 1:11, indicating significant economic returns [2] Group 4: Future Plans - Following the completion of marine species release, the province is preparing for freshwater species release, with plans to purchase and release various freshwater species into public water bodies from September to October [2]
