than in the REF site. \u00a0Blue Rockfish and Lingcod are approximately the same size in both MPA and REF sites. \u00a0Copper Rockfish are larger in the Point Lobos and Point Buchon MPAs and\u00a0Vermilion Rockfish are generally larger in the Point Lobos, Piedras Blancas, and Point Buchon MPAs. \u00a0Please note that many species and areas display a difference in length at the start of the sampling period (when MPAs were implemented in central California), which is likely due to initial differences in habitat quality.<\/p>\n<p>The above differences in mean lengths between MPA and REF translate into differences in biomass.\u00a0 Although CCFRP does not collect weight information on fishes caught, biomass estimates can be calculated for MPA and REF sites using established length-weight relationships from available literature.\u00a0When applying the spillover principle, additional biomass produced within MPA bounds can become available to the fishery.<\/p>\n<p>1: Wyllie
