THAILANDimposed for failure to comply with these requirements: Bhtl5 000 innorth west Phuket, BhtSOOO in south-west Phuket, Bht45 000 at Takuatung (PhaNga) , Bht33 000 at Thai Muang (Pha Nga) , <strong>and</strong> Bht39 000 at Churaburi (PhaNga) . In Pattani, each concessionaire pays a deposit of Bht7500, which isforfeited if the hatchlings are not released. However, supervision of therelease of hatchlings was said to be poor, <strong>and</strong> probably fewer than 20 000were released annually between 1965 <strong>and</strong> 1974 (Polunin, 1975).Under a programme begun in 1974, 50% of the eggs -from certain beaches wereremoved for incubation at fishery stations. Most of the eggs were ofL. olivacea , with some C. caretta , E. imbricat a <strong>and</strong> a few C. mydas . Underthis scheme, 1107 hatchlings were released in 1977, 4820 in 1978, 5213 in1979, <strong>and</strong> 3000-4000 in 1980. Experiments with farming were said to be beingcarried out at Phuket (Bain <strong>and</strong> Humphrey, 1980), <strong>and</strong> there were small-scalerearing efforts at Sattahip <strong>and</strong> along the coast at Changwat (Polunin, 1975).In Tarutao National Park, eggs are relocated from remote beaches toprotected areas, to prevent poaching. The hatching percentage was said tobe 80% for C. mydas <strong>and</strong> 60% for L. olivacea . Natural hatching rates arenormally higher, <strong>and</strong> so attempts were being made to conceal the marks leftby the nesting females to prevent poaching without the need to move theeggs. Early experiments looked promising (Ginsberg, 1981).521
