RED DRUM, SCIAENOPS OCELLATUS, TAGGING IN NORTH CAROLINA WATERS by Jeffrey L. Ross Tonya M. Stevens Sean A. McKenna and Beth L. Burns August 1987 North Carolina Department of Natural Resources and Community Development Division of Marine Fisheries P.O. Box 769 Morehead City, NC 28557 This project was conducted under the Federal Aid in Sport Fish Restoration Act (Dingell-Johnson Act) through the Wallop-Breaux Amendment, and funded, in part, by the U.S. Department of the Interior, U.S. Fish and Wildlife Service under Project No. F-29-1. RED DRUM TAGGING PROJECT IN NORTH CAROLINA WATERS Tagging of red drum, Sciaenops ocellatus, in North Carolina in 1986 proceeded along two avenues which will be described in separate sections of this report due to a) the different tags used; b) the different gears employed; c) the different personnel employed; and d) the different locations fished. The first section describes an intensive tagging program for yearling drum in the Pamlico River conducted for the first time in 1986 by DMF personnel in cooperation with local commercial fishermen. The second section presents results of tagging by sport fishermen cooperating with the Division of Marine Fisheries (DMF). This is the third year (and third annual report) of this cooperative program (Ross and Burns 1986). Most of this tagging activity takes place along the North Carolina coastal shorelines and on a broad size range of fish. Both of these tagging projects are continuing in 1987. SECTION 1 COOPERATIVE RECREATIONAL FISHERMEN TAGGING PROGRAM INTRODUCTION A preliminary investigation into the feasibility of tagging red drum, Sciaenops ocellatus, was begun in the fall of 1983 and tagging has continued through the 1986 fishing season (Ross and Burns, 1986). The objectives of this project are: 1) to determine various aspects of the life history and population dynamics of red drum, particularly seasonal movements and annual migrations of various size classes of red drum; 2) to determine age and growth rates of red drum in North Carolina waters; and 3) to determine mortality rates and describe the gear and user groups involved in the fishing effort on various size classes of red drum in coastal North Carolina. METHODOLOGY In 1986, 17 sportfishermen, 3 fishing guides, and the Raleigh Sportfishing Club participated in the voluntary tagging program (Table 1); the only fishing gear used was hook and line. All participants were provided with tags, -2- Table 1. List of volunteers participating in red drum tagging during 1986. Gary Austin Graham Farmer 1825 Lightwood Lane P.O.

Upon capturing a red drum, the fork length (mm or inches), date, and location were recorded as well as additional data, including time of day, wind, cloud cover, and tide. During 1986, Floy Stainless Steel Dart Tags (FH-69) were in use by all taggers, except for one who, due to the predominance of small puppy drum in his area, used both FT-1 and FH-69 tags. Two dollar rewards were paid for returned tags, at which time requests were made as to date, size, and location of fish when recaptured. RESULTS: During 1986, 263 drum were tagged (Table 2); the greatest percentage were released in October {n=136). Fish were caught in the following areas: 7 on Nags Head beaches; 115 between Oregon Inlet and Buxton; 15 on "the Point'' at Buxton; 13 in Hatteras Inlet area; 78 in and around Ocracoke Inlet; 16 between Topsail and Masonboro Inlets; 9 in Roanoke Sound; and 10 on Virginia's eastern shore. DMF personnel tagged 10 fish, 3 professional fishing guides tagged 57 fish, and 12 recreational fishermen tagged 196 fish (Table 3). Overall size composition of red drum captured and released The following data and Figure 1 summarize the size distribution of red drum captured and tagged by sport fishermen 1984 through 1986: Size Class (FL, inches) <18" 18'' - 40'' >40" Year Number Percent Number Percent Number Percent 1984 15 4.9 191 62.8 98 32.2 1985 36 11.9 127 42.1 139 46.0 1986 39 15.1 125 48.3 95 36.7 In 1986 there was a greater percentage of small and medium fish captured and a decreased percentage of fish greater than 40 inches.

The following data (and Figure 1) compare the size distribution of red drum captured and tagged between Oregon Inlet and the lighthouse at Buxton: Size Class (FL, inches) <18" 18" - 40" >40" Year Number Percent Number Percent Number Percent 1984 0 8 9.0 81 91.0 1985 19 17.8 88 82.2 1986 23 20.4 46 40.7 44 38.9 The number of small fish released around Oregon Inlet increased due to the efforts of a single fisherman. There were comparatively fewer fish >40 inches released than during the previous two years. The number of fish tagged on the Point (n=13) was similar to the number tagged in 1985 and less than in 1983 and 1984. The size distribution compared with previous years was: Size Class (FL, inches) <18" 18" - 40" >40" Year Number Percent Number Percent Number Percent 1983 37 82.3 6 13.2 2 4.4 1984 2 3.9 47 92.2 2 3.9 1985 1 7.1 11 78.6 2 14.3 1986 1 7.7 2 15.4 10 76.9 Ocracoke was again one of the leading areas for capture and release of red drum, due to the efforts of a single drum guide and a few beach fishermen.
