Group 1: Citrus Industry in Jiangxi - The honey pomelo has become a key driver for farmers' income and rural revitalization in Jiangxi, particularly in Jinan [1] - In Wanan County, the Fufeng Honey Pomelo Cooperative has over 6,000 acres of pomelo trees, experiencing a bumper harvest this year [3][4] - The cooperative has successfully addressed funding challenges by updating irrigation equipment and expanding planting areas [4] Group 2: Crab Farming in Hubei - In Hanchuan, Hubei, 320,000 acres of river crabs are being harvested, with an expected annual production of 45,000 tons [5] - Farmers have expanded their farming areas and installed new smart equipment to enhance production and income [7] - A specialized financial service team from the local postal savings bank has been established to alleviate the financing pressure on crab farmers [9] Group 3: Pearl Farming in Sichuan - In Kaijiang, Sichuan, 17,000 acres of pearl mussels are being harvested, marking the beginning of the harvest season [12] - Local villagers are actively involved in harvesting and transporting the mussels to a standardized processing facility for further processing [14] - The pearl mussel farming area has grown significantly over the past decade, producing 30 tons of pearls annually and exceeding a production value of 100 million yuan [16]

Group 1 - In July, the prices of various seafood products in Qingdao have decreased, with stable prices for most farmed fish [1][5][6] - Retail prices for specific fish include: 65 CNY per jin for tongue fish, 35 CNY for blackhead fish, 120 CNY for East Star grouper, 45 CNY for tiger grouper, 40 CNY for eel, and 22 CNY for turbot [1][5] - The trading volume of live seafood in the Qingdao Chengyang wholesale market has increased compared to the same period last year, with a total trading volume of 29,965 tons in July [6][7] Group 2 - The price of premium seafood has also declined, with small lobsters selling for around 100 CNY each, down from previous highs [3][6] - The market manager noted that the decrease in seafood prices has led to an increase in trading volume, indicating a positive market response [6][7] - Qingdao's active regulation and promotion of sustainable aquaculture practices have contributed to the stability of seafood prices during the closed fishing season [7][8]

Core Viewpoint - The article discusses the development of a unified audio-visual scene understanding model, emphasizing the need for models to possess general understanding capabilities similar to humans, rather than focusing solely on single-task performance [2][13]. Group 1: Unified Learning Paradigm - The current mainstream learning paradigm for multi-modal models overlooks the heterogeneity of multi-modal data and the complex relationships between tasks, leading to potential interference when tasks are jointly trained [2][13]. - A new paradigm for multi-modal large model learning is proposed, focusing on effective task cooperation from both data and model perspectives, surpassing specialized models in various scene understanding tasks [3][14]. Group 2: Data and Model Structure - The AV-UIE dataset is introduced, which includes explicit reasoning processes and specific temporal and spatial information to clarify the mutual assistance relationships between tasks [15][16]. - The proposed model architecture includes interaction-aware LoRA structures that allow for the decoupling of different capabilities, enabling tasks to share and benefit from enhanced abilities [21][23]. Group 3: Experimental Results - The Crab model demonstrates superior general understanding capabilities across multiple tasks compared to other models, as evidenced by comprehensive ablation studies and performance comparisons [26][30]. - The model outperforms specialized models in tasks such as AVE, ARIG, and AVQA, showcasing its effectiveness in enhancing performance through task cooperation [27][28][29].
