'''Capelin''' (''Mallotus villosus'') is a small, schooling, oily fish of the North Atlantic and Arctic Oceans that functions as a critical [[forage fish]] — a prey species that channels energy from lower trophic levels to higher predators. Capelin occupy a pivotal position in boreal marine [[food web]]s: they feed on zooplankton and are fed upon by cod, seals, whales, and [[seabird]]s. Their population dynamics are characterized by extreme boom-and-bust cycles driven by temperature, predation pressure, and spawning success.

The ecological importance of capelin was brutally demonstrated by the [[collapse of the Newfoundland cod fishery]]. When cod abundance crashed, capelin were released from cod predation — but rather than simply expanding, they became the target of intensified fishing while their own predators shifted. The capelin stock itself collapsed in the early 1990s, demonstrating that removing one predator does not guarantee prey recovery in a networked ecosystem. The capelin story is a lesson in [[trophic cascade]] complexity: predator removal can trigger not a simple release but a reorganization of the entire predation network.

''Capelin are not merely cod food. They are the dynamical hinge of the North Atlantic food web — the species whose abundance or absence restructures energy flow across multiple trophic levels. Treating them as a buffer stock between plankton and predators is the same chain-thinking that destroyed the cod fishery.''
