Core Insights - The article discusses the growth and significance of cage aquaculture in China, highlighting its advantages in increasing yield and management efficiency [1][5]. Group 1: Overview of Cage Aquaculture - Cage aquaculture utilizes floating devices to place aquatic products in the mid-water layer, facilitating feeding, growth observation, and mechanized harvesting [1][2]. - It is a crucial part of industrialized and intensive aquaculture, allowing for layered farming and optimal use of water space, significantly enhancing production [1][2]. Group 2: Growth and Production Statistics - In 2024, China's cage aquaculture area is projected to reach 179.7 thousand hectares, a year-on-year increase of 10.5%, with a production volume of 2.251 million tons, up 19.5%, accounting for 8.9% of total marine aquaculture production [1][5]. - The average yield from cage aquaculture is expected to reach 12.5 tons per hectare in 2024, reflecting a growth of 0.09 tons per hectare from 2023 [1][7]. Group 3: Regional Distribution - Cage aquaculture is predominantly concentrated in Shandong Province, which will have an area of 149.0 thousand hectares in 2024, representing 83% of the national total, with a production of 1.6092 million tons, accounting for 71.5% of the national output [1][8]. - Yantai City in Shandong is identified as the largest cage aquaculture base, with 123.45 thousand hectares and a production of 109.25 thousand tons, making up 67.9% of Shandong's total and 48.5% of the national total [1][11]. Group 4: Industry Impact - The development of the cage aquaculture industry plays a vital role in national food security, the supply of high-quality protein for humans, and the construction of a blue granary [1][5].
