The Isolation:
As tide retreated, some fish became trapped in tidepools—unable to return to open water, isolated until tide returned. The forager could catch these fish with bare hands, nets, or improvised weirs.
The Species:
Various small fish inhabited tidepools—blennies, gobies, small flatfish. None were large individually, but in aggregate they provided meaningful protein.
The Nets and Weirs:
More sophisticated foragers constructed temporary barriers—stone arrangements funneling fish into confined areas, nets strung across channels, baskets positioned to trap fish carried by retreating tide.
