The most common type of fishing gear found in Chumash archaeological sites in present-day coastal California is the single-piece curved fishhook made from bone or hell. The best archaeological evidence that the Chumash also used nets are grooved and notched stones. Such stones could have weighted nets and have been found at a number of late period sites, although ethnographic sources suggest that these apparent sinkers may have been attached to a line for a fishhook. At one Chumash site, the 7,655 identified otoliths (ear bones) from white croaker fish were close to the same size. Archaeologists have proposed that the uniformity of the otoliths indicates that the croakers were captured with gill nets which would trap fish within a narrow size range.
