Primes¶
- Recruitment Variability
- The decisive structural fact is weak stock coupling: a stock-recruitment plot of year-class strength against parent spawning biomass scatters by two orders of magnitude with almost no slope — a large adult stock does not reliably make a large cohort, because the bottleneck is larval survival in the window, not egg supply.
This sourceMeta-analysis of 364 stock-recruitment series documenting that the spawning-stock-biomass–recruitment relationship in marine fish is frequently weak and scattered, with strong recruitment possible across a wide range of stock sizes.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
