Peruvian Anchoveta / 鳀鱼

Peruvian anchoveta is the small fish at the center of 商业小样45 | 厄尔尼诺越大，鱼越贵. The episode begins from snack “deep sea fish” but quickly reframes anchoveta as an industrial feed input: the fish is small, oily, and not especially attractive as direct food, but it can be processed through cooking, pressing, drying, and grinding into fishmeal and fish oil.

The species matters because its population responds quickly to ocean conditions. In the source’s account, El Nino weakens cold-water upwelling, reduces plankton, and can sharply reduce anchoveta biomass. That turns a marine ecological cycle into Aquaculture Feed Dependency and consumer seafood-price exposure.
