VIRGINIA INSTITUTE Of. MARINE SCIENCE SCHOOL OF MARINE SCIENCE January 9, 1981 Mr. Bernie Caton Legislative Services 2nd Floor P. O. Box 3-AG 910 Capitol Street Richmond, Virginia 23208 Dear Bernie: Just prior to the Christmas holiday you asked Dexter to prepare a definition of a naturally productive oyster bottom. After considerable thought, we arrived at the definition which is enclosed with this letter. As you will see, this definition utilizes concepts derived from our four-year study of Baylor bottoms. This study is now in its final stages. When it is completed copies of the charts showing bottom types, as well as a text discussing other aspects will be forwarded to various State agencies. If desired, copies can be prepared for ::£gislative purposes. · , .··, ·,·--~, , 't~_· ,. ··:~_· ,··: · ~···~1J!~t~~~w~,h~~~"~•~l,i~i' .· ,(~!Mlt;s;\~i~:i~#,J·P~,MP:G~~Ji;Liiil':V•~~' :6\/t;"ii/§;«ir.r./W,t<,•·' '''47•H;:~""'""j"' l ~t~~liir~4'-\~t"?"'1:'lr.'Clr'fou'"'TS' 1''clC'CUra:ce ,,.

Hargis, Jr. Virginia Institute of Marine Science and School of Marine Science, The College of William and Mary Gloucester Point, Virginia 23062 January 9, 19·81 A natural oyster rock is defined as a productive area of bottom which has a functional set which will support a reasonable level of commercial harvest for market or seed oysters. A set may typically occur each year, but the I r I /. , annual interval between sets may be as long as 15 years. ; ·\-fft~~'oiftsl/i'61fJ'.'i1~/lee{;'§'frlit,4rli:~:1·:"''i~~~£'l~flJvif!;,,,~~,¥ff~:ft~!\t,i:f'!'.~~711~lf~f~Ni''··-::~m ! classed as rock, mud-shell, sand-shell or buried shell as defined by the Baylor Ground study to be completed by the Virginia Institute of Marine Science in April 1981. Moreover, the total volumes of shell, oysters and cinder in the substrate in any designated areas should equal or exceed on the average 10% by volume of the material in the upper five inches of the bottom. r.
