There is no limit number on starry flounder but the question came up as to if the overall 20 fish limit would still apply. I asked Ed at Fish & Wildlife who said no. Thus it should be the same on all fish listed below under 27.60 (b).
27.60. Limit.
(a) General. No more than 20 finfish in combination of all species with not more than 10 of any one species, may be taken or possessed by any one person except as otherwise provided or as defined in sub-section (c) below or in Section 195. See sections 27.70 through 28.62 for special bag limits, minimum size limits and poundage restrictions for certain species that apply in addition to the general bag limit.
(b) There is no limit on the following species: anchovy, grunion, jacksmelt, topsmelt, Pacific butterfish (pompano), queenfish, sanddabs, skipjack, jack mackerel, Pacific mackerel, Pacific staghorn sculpin, round herring, Pacific herring, Pacific sardine, petrale sole and starry flounder.
