Core Viewpoint - The article discusses the balance between protecting the water quality of Dongting Lake and promoting the healthy development of the aquaculture industry, highlighting the shift from traditional fishing to ecological fish farming in the region [1][2]. Group 1: Ecological Fish Farming - The main fish being cultivated in the area is the "ecological fish," specifically the fat head fish, which is sold at prices two to three times higher than ordinary pond fish due to its natural rearing method [1]. - The ecological fish are raised using the "human release, natural growth" method, where no feed is provided, allowing the fish to grow on natural microorganisms and aquatic plants [2]. - The local government has unified management of over 40,000 acres of aquaculture water surface to promote green transformation in the industry, achieving ecological, economic, and social benefits [1]. Group 2: Economic Viability and Market Strategy - The ecological fish grow slowly, taking a year to reach one to two pounds, compared to four to five pounds for ordinary pond fish, necessitating a market-oriented approach to ensure stable income [2]. - The fat head fish is specifically targeted for the popular dish "chopped pepper fish head," which has high market demand and stable prices, with distribution primarily through cold chain logistics to the Guangdong-Hong Kong-Macao region [2]. - The region is also integrating ecological tourism with fish sales, creating attractions such as bird-watching spots and selling rare fish species like the black shell crucian carp at prices between 30 to 40 yuan per pound [2]. Group 3: Technological Advancements - New aquaculture technologies are being adopted to enhance the value of the fishery, including the establishment of fully enclosed indoor fish ponds that utilize microorganisms to remove ammonia nitrogen from the water [2]. - The local government is constructing a drying fish processing plant and developing online live-streaming platforms to improve cold chain logistics, thereby continuously releasing ecological benefits from the green environment [2].
