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 [[FishmealSupplyChain|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.
