鲟鱼是目前地球上是最古老和最原始的辐鳍鱼类。近20年来,因环境污染及沿江、沿河修建引水工程及筑坝而阻断了其洄游通道,使其生态系统遭到了严重破坏,致使有些种类已濒临灭绝。鲟鱼鲜美的口味,丰富的营养,堪称鱼类之最,皮可制革,而且是优质特种皮革,鱼卵可制作成鱼子酱,且国际售价达几万美元一吨。总之,鲟鱼浑身是宝,具有“黑色黄金”之称,人工工厂化养殖的经济价值极高。 Sturgeon is by far the oldest and most primitive species of finfish on earth. In the past 20 years, some species were on the verge of extinction due to environmental pollution and the diversion of waterways and dams along rivers and dams that blocked their migratory routes and severely damaged their ecosystems. Sturgeon delicious taste, rich nutrition, called the most fish, leather can be leather, but also high-quality specialty leather, fish eggs can be made into caviar, and the international price of tens of thousands of dollars a ton. In short, sturgeon whole body is a treasure, with “black gold,” said artificial high value of factory farming.
