Consequently, the stated objectives for furthe r evaluating the weir s du r ing the project year could not be completely fulfill e d as anticipated . The bri e f obser vations made in this proj e ct year and in project rep o rts F - 20 - R-1 and F-20-R-2 are summarized herein with p r oj ect recommendations. II Background : Bowfin, yellowbelly sunfish , giz z a r d shad , bay a nc hovies, tide- water silversides, striped mullet, bro w n bullhead , blu egill , European carp, American eel, needlefi s h, largemouth bas s , spo tte d ga r, golden s hiners, and various clupeids were suc ces sfully killed in th e wei r a ssem bly du r ing routine flooding and op er ation. Fi sh were ob serve d b eing d eterred from the outermost assembly unit while o t h er s were observed , during ra pid flow, t o b e d r ifting to the intake trunk, apparently only partially e l e ct r onarcoti ze d . In a mor e e xten - )- sive evaluation u. in g a blockoff net to entrap the s e d ri ft i ng fish, it was found that flooding with weirs in op er ation appa re ntly kill e d stri p e d ba ss , stri ped mullet, la r gemouth ba ss, and Am eri can eels, as e vid e nced by fi s h accumulating in the blockoff a re a. A larg e numb er of small fish of various ty p es were recover e d alive from within the blockoff n et. Ho wever, th e point of en tr y in t o the blo ckoff area was qu e stionable du e to di ffic ulty in secu r ing the n e t on the s ub s trate and be - cause o f the on e half inch mesh size of the n et . Brief exposures from three to 15 minutes in a ;1b n '- conductive container ~ \1 were not adequate to kill adult resident bream and bass a distance of three to four feet from the electrodes .

However, it was 85.7 per cent in one 18 minute test and pro - ~1!)\ gressively lower from one 10 and a three minute exposure. Mortality in channel fatfish fingerlings (1. 87 - 2. 68 inches) shocked three a nd ten min- utes was 30 per cent; and in fingerlings shocked 15 and 18 minutes, it was 70 and 50 per cent, respectively. III Objectives: 1. To determine the most effective means of preventing the entrance of river fish into a public fishing area. 2. To determine the degree of residual effects upon native fish "shocked" ,., for various time intervals. 3. To investigate the extent of mortality of larval fish flushed into the lake. IV Procedure: Procedures for data summarized in this project report are presented in Project Reports D.J.; F-20-Rl and F-20-R-2. V: Results: In additional tests complete mortality of adult bluegills was ,. achieved in a 15 minute exposure, with 80 per cent killed in five minutes. Fingerling bluegill and redear sunfish were less susceptible with complete mortality achieved in 20 minute exposures only. Fingerling largemouth bass were the most susceptible test species with complete mortality occurring in one five minute test and a 70 per cent kill in one 15 minute exposure. 2 > VI Recommendations: > 1. A substitute approach should be used for flooding the public fishing lake. Electric weirs should be used for preventing entry of rough fish in a "freshwater lake" in the event river water flooding via the system used is necessary; however, it is doubtful if complete deterrence or mortality of rough fish can be accomplished. Such a device would, however, reduce the number of fish and be quite effective in reducing the number of adult rough fish. Alternatives would be to flood and treat with rotenone or antimycin cir pump water into the basin at selected periods. 2. If an electric weir assembly is used in conjunction with flood gates for rough fish control, the gates should be screw-down type to allow controlled velocity of flow through a weir assembly. 3. A weir assembly , if used,should consist of two basic assembly units. One assembly unit should transect the flood ditch adjacent to the river with a greater span than 12 feet used in the present study. This will lengthen the gradient of the electritl field and make it more effective as a deterrent, electronarcotizing less fish approaching the river side of the assembly . The second assembly should be constructed within the flood ditch and positioned parallel to it to allow continuous .. , exposure to drifting electronarcotized fish and to fish sinking to the ,... -. ""=' . substrate. 3 State: _Q~~~------------- ~r. o j e c t Tit 1e: .f~..!.!.!..~.L.B-~..82.,!!___ ------ project No: _E_:_~Q_:_Ii_:_~----------- Job No: 1-2 Job Title: .. .. I Summary: This job was terminated the previous year. The results obtained prior to this report are summarized with related project recommendations. II Background: During the study the native largemouth bass spawned with heavy fingerling survival in the lake. Randomly taken samples of the soil in the basin indicated that these progeny were produced where pH values v.aried f r o m 4 . ~ t ;; 4 . 5 . Spawning and successful hatches occurred in an experimental plot where soil pH in flooded areas was determined to be 4.8 to 5.1 and where brood fish were stocked at 1, 054 per acre. A slightly higher hatching success was observed in an adjacent plot in which six inches of coarse sand was added. The stocking rate of broodfish was 744 per acre and soil pH was determined to be 5. 6 to 5. 8. Spawning in both plots occurred periodically over an eleven day period when hydrometer readings indicated that the salinity varied from 2. 48 to 3. 07 parts per thousand. Bluegill or redear sunfish progeny did not appear by June 21 from 66,000 two-inch fingerlings stocked into the lake in mid February. Bluegills stocked in experimental pens with the substrate covered with sand swept nests and appeared to have swept nests on the natural substrate in the other plot. However, no fry or fingerlings were collected. Soil pH values were determined to be 5.4 to 5.5 and 4.8 to 5.0, respectively, in the pens and the water salinity during ... 4 the spawning season exceeded 3.0 parts per thousand . Other species spawning heavily in the lake included black crappie, golden shiners, and speckled bullheads. Edaphic factors or salinity did not prohibit largemouth bass or blue- gill from reproducing in an adjacent 40-acre impoundment filled partially with rainwater over a two-year period. Soil pH of randomly collected samples in this basin varied from 5.5 to 6.5 and the water salinity from 2.45 to 2.89 parts per thousand. III Recommendations: 1. The use of artifically prepared spawning areas did not significantly . influence spawning and it is doubtful if would contribute signif- . r icantly to the establishment of a good fish population in the lake 2. Stocking per acre should consist of 1, 000 bluegill and redear and 120 largemouth bass if fertilization is to be accomplished. Early bass stocking is advisable to help alleviate a potential rough fish problem. A supplemental forage species, such as the threadfin shad, should be experimentally stocked if checks indicate low bluegill and redear productivity in the lake. 3. Soil pH measurements indicate the probability of low productivity; however, after flooding periodic samples should be taken to determine the increment of increase and need for liming . ' . 5 .

Specimens collected during F-20-R-2 and previously tentatively identified are reported as complete as possible to date and summarized in this report with current year data. Croaker, spot, striped mullet, Southern flounder and pickerel could be flooded into the public fishing lake in low densities in January based on this sampling. February, March, Apr i 1, May and June w o u 1d provide 1i mite d 1a r v a 1 fish of any type . J u 1y and August flooding would provide higher populations of whit e and channel catfish - with some hogchokers (T . ma c ulatus). --::- ~ ---- Early Sep t em b <:. r flo oding would provide larval fish presumed to be gray snapper. October flooding would provide croakers and hogchokers. November was not a productive collecting period, Populations of marine larval forms are considered to be of low density by the author with few of the 17 known species collected of sportfishing value . Sa li n i t i e s a r e d e c i d e 1y t0o 1o w t o a tt e m p t c u 1t u r e o f m a r i n e s p e c i e s II Background: Since 1948, experiments have been conducted on pond cultivation of a variety of estuarine or saltwater species of fish at Bears Bluff Laboratories, South Carolina. Considerations were given in this study to the possibility of utilizing a 200 acre site on Champney Island in Mcintosh County for this type ... fish culture or as a "freshwater lake" The prospective area is located in the estuarine complex of the Altamaha River System and is adjacent to Middle River. Consequently, it can be flooded 6 from this stream by manipulating flood gates when desired . Th is land has been described in the previ o us report from sur ve y s of the U S De p art men t ' ' of Agriculture . This area of Mcintosh County is composed of we t alluvial type land (Altamaha Clay) which reacts strongly add to Soil Text Tests. The land is farther inland than tidal marshes, which give an alkaline reaction ; but it is still influenced by tides and alkalinity of the tidal influx . With open flood gates the area is covered with brackish water when tide s a r e pushed by high winds, and it is swept with fresh water when rivers overflow their banks. Salinity measurements and specie s of larval fi s h found in Middle Rf ver during the period January 10, 1966 to August 3, 1966 have been partially submitted previously (D.J.; F-20-R Reports, 1966 and 1967). Additional information is included herein. !!!_~.!.2.!~!..~Y_e_'!}~~_! Swingle (1956) J:eports the exact limits within which largemouth bass and bluegill will successfully reproduce to be unknown. He als o suggests that bass can reproduce at a slightly g. reater salinity than bluegills. Water with a salinity of 5 ppt. or above is apparently unsuitable for reproduction by either species. Neely (1962) reports these species thriving in salinities up to 5 ppt.! however , reproduction ceases at salinities above 2 . 5 to 3. 0 ppt. Luntz (personal communication) reported bluegill and bass in water of 8.0 ppt. salinity but they were not reproducing. Largemouth bass and bluegill are r eported by Tebo and McCoy (1964) to be distributed where sea-water concentrations ranged from 0 to 29 per cent (0 to 10 . 26 ppt.) and 0 to 10 per cent (0 to 3 . 5 6 ppt.), respectively , with a sharp decrease in numbers of bass in waters having more than 10 per cent sea-water. On the basis of bio - a s say studies, these authors indicate that 7 ,. 1o to 12 p e r c e n t s e a w ate r ( o s m o t i c p r e s s u r e of 2 . 3.4 t o 2 . 8 0 a t mo s p h e r e s ) '. or 3. 5 6 to 4.26 ppt. salinity is the maximum concentration at which largemouth bass can successfully reproduce . Hatching of e gg s taken by hormone injection and manual stripping of females occurred where salinities were as high as 7. 0 8 ppt. ; however , the incidence of mortality during pro-larval development was high at 5. 32 ppt. or higher. The max i mum concentration for normal egg development of largemouth bass was surmised to be between 3.56 and 5. 3 2 ppt. Surber and Taft (1962) report largemouth bass and bluegill eggs and fry c a n survive in salt water up to about 10 per cent sea strength. Carver (1966) concluded that salinity was a major factor which limited distribution of centrarchids on Delta National Wildlife Reguse in the Mississippi River Delta. In his studies, largemouth bass were collected in salinities that ranged from 0. 04 to 4 . 10 ppt. Young-of-the-yea r bliack crappie were collected in water with a salinity of 2 . 00 ppt. and several adults were collected in a reas which reached 43 per cent sea water (14.43 ppt.) 4 months later . The author cites studies in the Cape Fear River in which black c rappi e were found in waters with salinities up to 4.7 ppt. This speci e s was observed in greater number, however, in fresher waters. I White crappie were found in limited numbers in water salinities up to l. 32 ppt. and were considered limited in their distribution by_: relatively I low salinities . I > Redear suufish and warmouth were found at a maximum salinity of 4.1 ppt. The author c ites Geagan (1962) in studies of Lake Borgne, Louisiana, in I which redear sunfish were found in salinities ranging from 2. 6 to 6 . 7 ppt. Bearden (1967) in summarizing some of the work at Be a r s Bluff Laborato.ries South Ca r olina, surmised, "findings indicated that saltwater fish ponds should 8 be built in areas where the salinities average at least 10 parts per thousand. New water should be taken in during high tide or pumped in frequently, especially during hot weather to avoid possible excessive phytolankton growth and subsequent oxygen depletion. Very low salinities seem to inhibit growth of many species and to limit productivity in general. Two to three hundred pounds of fish per acre annually have been regularly produced in unfertilized, unfed ponds. This production is made up primarily of herbivores (Mullet), but recent accounts of 200 pounds of red drum and spot are made. Red d r u m (_cJ3~.E..9..P.! ~~!_~a_!3) w i 11 enter by f 1o odin g ponds on the South Carolina Coast during September to November and post-larval spot LL_eJ.9.!.!..C2_IE~ ~!~.!..1.!..~~~1 are present in 1a r g e numbers in Feb r u a r y and March. Red d r u m proved to be the species most adaptable to pond conditions; but good results were also obtained with spot, black drum and southern flounder. The author speculates on a possible combinarion of red drum and spot at stocking rates per acre of 50 to 75 drum and 300 to 400 spot. Red drum, stocked as juveniles (2. 5 to 5. 5 TL) in tanks, with controlled conditions, increased 55 to 60 per cent in total length in 2 1/2 months. Record size spot for South Carolina (ll.8 inches and 13.5 ounces) were grown in ponds in 3 years. Tarpon and 1ad y fish thrive in s a 1t -w at eD ;,p o nd s during w a r mer months b u t could not survive the winter months in the Bea rs Bluff area. During 1962-66 a single fish kill was reported by the author. In a 2.5 acre pond with a max1. mum dept of 7 feet the water temperature dropped to 33 . 4 0 F. in 3 days with a near complete kill of spotted seatrout and croakers and a partial kill of spot and red drum. Duebler and White (1962) in a 33 day laboratory experiment with summer flounder did not encounter lethal salinities in a range of 10 ppt. to 40 ppt. 9 w h ere i'llcrements were of 10 ppt. These fish exhibited increased growth ~< rates with increasing s alinities , with a marked reduction at 40 ppt. These authors cite studies by Deubler (1960), with salinitie s of 0 to 30 ppt . in which postlarvae of the s outhern flound e r, _!'~_:~!_~c_~_y~ !_~~h_?_!_!.!,_g_JE~ attained a larger size at high salinities with controlled food supply, temperatur e , space and light .

III Objectives: The objectives of this phase are : (1) to determine salinity of water that would be available for flooding into a public fishing area , (2) to determine larval fish forms that might be flushed into the public fishing area, --. -::: .. and (3) , to survey literature on the larval forms found to determine salinity requirements and tolerance levels. IV Pro ,ced ure: . ' \ .. Sampling was conducted eight river miles from the Atlantic Ocean in Champney River at u.s. Highway 17 Bridge . This area is in very close proximity to floodgate number one of the proposed public fishing area. Standard procedures consisted of surface sampling at approximately two week intervals. Flood tide sampling was conducted from 0 to 2 hours prior to the high water given for Tybee Outer Bar and at high water at the sampling . s tation. A bench marker indicating the flood l e vels available for the proposed . fishing area was set up and data is related to the Tybee Bar tide data . Salinities 10 were determined with a specific gravity hydrometer. The sample depth, pH, water temperature, total hardnes s , dissolved oxygen, s alinity and relative tide level were periodically determined. Samp ling was c ond uc ted in conjunction with water sampling. Samples were taken with a 1/2 meter egg net (Ace mesh 14 p~ t inch) set for 30 minutes on A.M. and P.M. flood tides approximately 1 hour 30 minutes prior to Tybee Bar high water and on A.M . and P.M. ebb tide shortly after high water at the sampling station. V Results: During the period January 10, 1966 to December t,,.4, 19 66 salinities at the sampling station in Middle River during flood tide varied from l. 20 to 3. 2 2 ppt. with a calculated mean of 2. 32 ppt. During the same period high water salinities varied from 1.35 to 6.40 ppt. with a calculated mean of 2.70 ppt. The range and mean salinity and temperature values by month for the 1966 calendar year and January and February of 19 6 7 are presented in Table l.

These data would indicate January flooding would provide the largest number of croaker, spot, striped mullet, Southern flounder and pickerel in the lake. July or August flooding exclusively would entrap a significant number of channel catfish, white catfish and hogchokers.

These fish were collected, primarily, electrofishing 11.5 to 22.25 mile s above Tybee Knoll Spit in the three lower rivers of the Savannah System \~ and from 10 .3 to 24 . 5 miles above Ossabaw Sound in the Ogeechee River '~ System during the period October to mid April. Two hundred seventy- three of these , ranging from 0 . 13 to 32.0 pounds, were transported to Lake Blackshear for stocking. I I> Catch per man-day of effort electrofishing during the 1966-67 period for the Ogeechee and Savannah River Systems was approximately 0.21 and 3.11 fish, respectively . Electrofishing was the most effective collecting technique tested in 1967-68. The average catch per man-day of effort was 5 . 07 and 3.67 fish for the Ogeechee and Savannah River Systems, respectively-:' j Stripers were collected most consistently and with least effort at two locations, the Georgia Power Company hot water discharge in the Savannah Fr o n t R i v e r , o n e m i 1e s o u t h o f H i g h w a y 1 7 , a n d t he S e a b o a r d Co a s t 1in e R a i 1 - road tressel in the Savannah Back River , 1.2 miles north of Highway 17 - A . A total of 2, 996 fingerlings striped bass were reared from fry obtained by ovulating brood fish collected in this project year. 27 II Background: Georgia has twenty-two large reservoirs comprising 3 3 0 0 0 0 acres , se ve r a 1 o f w hi c h c on t a in si g n i f i c a n t p o p u 1a t i o n s oi gizzard shad. A biological control of this segment of the fish population and a subsequent increase in sport fishing may be possible with the s ucce ss ful establishment of this species. It is presently unknown if I' r e p r o d u c t i o n o f ts~t r i p e r s a n d c o n s e q u e n t r e c r u i t m e n t w i 11 o c c u r i n a n y ' 'V of th e reservoirs from a few broodfish or if a fishery will necessarily be provided by a put - grow-take program. Efforts were initiated to establish this species in Lake Blackshear from sub-adult and adult stocking during 1965-66. A very limited number of areas on the Georgia coast where significant numbers could be co 11 e c ted w e r e d e t e r m i ~~;;:.,[o;.I i n t hi s i n i t i a 1 s t u d y y e a r ; how e v e r , add i t i on a 1 information on distribution was obtained each year. A total of 323 striped bass were collected from various sources and areas during the year prior to this report ( 1966-67 ). One hundred fifty one of these, ranging from 0. 6 to 32.0 pounds and averaging about three, were successfully transported to Lake Blackshear and stocked. Distribution studies of the striped bass on the coast and further collecting and stocking in Lake Blackshear was conducted in this project year. 28 III Objectives: To collect information on the availability of sub-adult and adult striped bass that could be used for stocking other areas. Additional stated objectibes, procedures and results for Job II-I for the project year 1967-68 are presented in the publication, A Preliminary Report on Fry Production an d Rearing of F in g e r 1in g S tripe d B ass , _R_o_c_cy_! ~~!~.!..02~ Walbaum at Richmond Hill Fish Hatchery in Georgia .

Survey areas included Jerico Creek, Gresh, Belfast, Ogeechee, Little Ogeechee, Altamaha, Savannah, Savannah Middle and Savannah Back Rivers and several tidal creeks of each stream. Stripers collected were retained in concrete fish distribution vats at Richmond Hill warmwater hatchery one to three days to accumulate a desired number, dipped for 30 seconds in 1:4000 malachite green and transported in a tank truck with agitators and an oxygen supply approxi- mately 185 miles to Lake Blackshear. The water temperature during transport was maintained near 65F. A brief section on disposition of fingerlings rear e d with general information is included herein. Distribution and collection data in this report will represent the fish stocked in Lake Blackshear, fish preserved for related project studies, those tagged and released in the AFS Project, and those utilized in 29 hatchery propagation studies. Several studies were conducted simulanteopsly and distribution data recorded on all striped bass collected were inseparable. V Results: Collection of Adult and Sub-Adults: The areas most frequently surveyed are illustrated in Figures 1 through 4. The most productive sites are indicated, points of collection for female broodfish taken in the spring of 1968 for hatchery experiments are indicated on figures 2 and 3. Table 1 summarizes striped bass sub-adults and adults transported from Richmond Hill Hatchery in 1966-67 and 1967-68. The group was comprised of 273 fish, ranging from 0.6 to 25.0 pounds, several mature males; 3 large spen,t females above 8. 0 pounds and several females that should be eligable broodfish in 1969 or 19'1"0.

Stripers are more concentrated in the zone of effective electrofishing of Savannah and Ogeechee systems during the period November to late April. As the water reaches about 55 0 F . they app e ar to begin to disperse, ascending the r iver on the spawning migration. If future collections for stocking are made electrofishing, they should be limited to periodi c efforts as the hot water dis c harge in January, Februa r y a n d March and at the railroad trussel on the 47 . Back River. 2. Investigations with pound nets as a mthod of collecting adults and sub-adults should prove more feasible as fewer man days of effort will necessarily be expended. 3. With advanced technology in rearing fingerlings reported by various states, previous success in Georgia, and considering ' ~ the extensive expense of obtaining stockings in this manner, it i s suggest e d t hat future stockings exclude adult and sub-adult stocking. Collection and hormone spawning of broodfish and fingerling r ea-ring is feasible. ,. 48 LITERATURE CITED Tebo, Lee B. and Edward G. McCoy 1964.
