Section 11-1305. Size and catch limits

The  department  may  promulgate regulations restricting possession on
  the waters of the state, except the  marine  and  coastal  district,  of
  fish, except bait fish named in section 11-1315 of this title, that have
  been  cleaned, filleted or skinned in such a manner that (a) the species
  of fish taken cannot be identified, (b) the number of fish taken  cannot
  be  determined,  or  (c) the length of fish taken cannot be ascertained.
  Such regulations shall initially provide that walleye, largemouth  bass,
  smallmouth  bass,  brook trout and lake trout may not be so possessed if
  they have been dismembered, filleted or otherwise prepared  for  cooking
  or  consumption  beyond  removal of the gills and viscera and that other
  species of fish may not be so possessed if they have been dismembered or
  otherwise prepared for cooking or consumption, except that the gills and
  viscera may be removed and such fish may be filleted, provided the  skin
  is not removed from the fillet.
