Core Insights - The article discusses the confusion surrounding the various types of fish marketed as "cod" in the market, highlighting the significant price differences and potential health risks associated with consuming mislabeled fish [1][4]. Group 1: Types of Cod - True cod belongs to the Gadidae family and includes four main species: Atlantic cod (Gadus morhua), Pacific cod (Gadus macrocephalus), Greenland cod, and Alaskan pollock (Gadus chalcogrammus) [2]. - The Atlantic cod is primarily found in the North Atlantic, while the Pacific cod is distributed along the North Pacific coasts, including China's Bohai and Yellow Seas [2]. Group 2: Related Fish Species - Cod's close relatives include blue cod, yellow cod, and green cod, which belong to different genera within the Gadidae family, and are generally of lower quality and price compared to true cod [3]. - Distant relatives, such as oilfish and basa fish, are often misrepresented as cod in the market, leading to consumer confusion [4]. Group 3: Market Dynamics - The market is flooded with counterfeit "cod," primarily oilfish and basa fish, which are sold at lower prices and can cause health issues like gastrointestinal distress [4]. - A recent collaboration between Yantai Haihe Group and China Petroleum aims to promote the domestic sale of Alaskan pollock at significantly reduced prices through online platforms [5].
