YEMEN,PEOPLE'S DEMOCRATIC REPUBLICThere are extensive seagrass pastures off the Somali coast as well asimportant nest beaches <strong>and</strong> significant exploitation (Travis, 1967);exploitation in Somalia will thus affect turtles nesting in Yemen (FDR) aswell as turtles nesting locally.POPULATION: Eretmochelya imbricataNesting sites Significant Hawksbill nesting has been recorded on PerimIsl<strong>and</strong> in the Straits of Bab al M<strong>and</strong>ab (the western extremity of mainl<strong>and</strong>PDRY) , <strong>and</strong> on Jabal Aziz Isl<strong>and</strong>, just off Ras Imran , around 50 km west ofAden. At least three beach zones exist on Perim: False Bay Beach, 365 mlong; Sh<strong>and</strong> Bay Beach, 360 m; Ras Sheikh Berkhud, a series of smallscalloped beaches each c . 20 m long; <strong>and</strong> an unnamed beach midway between thelast site <strong>and</strong> Obstruction Point. The Jabal Aziz nest site is a single1.6 km beach facing B<strong>and</strong>ar Imran. There may also be some nesting onSokotra. (Hirth, 1968).Nesting numbers No new nests were seen on a survey of Jabal Aziz inOctober 1966, but moderate numbers were found in 1967: 30 January, 5 nests;1 February, 17; 2 February, 8; 8 February, 16. On Perim, no nestingactivity was observed 3-7 December, but there were signs of its occurrencein the "rather recent" past. Six old nests were seen on Sh<strong>and</strong> Bay Beach <strong>and</strong>about 30 on Ras Sheikh Berkhud. Small numbers of Hawksbills were seen offshore. One female emerged to nest on 24 January.The sparse data do not allow firm estimates of nesting numbers. The JabalAziz figures suggest a mean nightly emergence of about 11 females, if thisis continued throughout January <strong>and</strong> February, there may be around 650Hawksbill nests a season, with perhaps 200 females (if each nests threetimes). According to published evidence, Perim has considerably lessnesting habitat <strong>and</strong> there is less direct evidence of nesting; if nestingtakes place at half the Jabal Aziz rate, some 100 females may be involved aseason. Ross <strong>and</strong> Barwani (1982) suggest an approximate total of 500Hawksbills nesting annually in PDRY.Nesting season Nest body pits found on Perim on 3-7 December 1966suggested that "some rather recent" nesting had occurred. Local inhabitantsreported that December <strong>and</strong> January are the main nesting months. Nesting hasbeen directly recorded in late January <strong>and</strong> early February, but presence oftwo sets of ovidical eggs in a Jabal Aziz female that laid on 1 Februarysuggests that laying continues until at least the end of February. Similarfinding apply to Perim Isl<strong>and</strong> also (Hirth, 1968).Migration No direct information. All Hawksbills observed on Jabal Azizwere heavily encrusted with barnacles (Hirth, 1968), possibly suggestingrelatively sedentary habits.EXPLOITATIONCommodity The coastal Arabs <strong>and</strong> the Bedu eat both the meat <strong>and</strong> eggs ofC^ mydas , but not on a large scale. Hirth (1968) reported that turtle wasusually only consumed in villages where fish was not readily available. Heindicated that the Kuria Muria Isl<strong>and</strong>s was the only locality where turtleswere actively hunted for local consumption. In Socotra too, C^ niydas wascaught when the opportunity arises, the females being generally preferred.Out of 22 localities along the southern Yemen coast, Hirth (1968) reported066
