...INTRODUCTIONExcept for the nesting season, sub-adult turtles are present near the nestbeaches in good numbers throughout the year; they move opportunisticallyalong the Atlantic coast, northward in summer and southward in winter.Table 2. E. imbricata : mean size and productivity data, mainly afterLimpus et al , (1983, and sources cited therein). Additional data:Tortuguero^ - Bjorndal et al , (1985), Seychelles^ - Brooke and Garnett-^(1983), Mortimer ( in litt , 31.12.87, opinion based on work in prep.),Puerto Rico - Olson (1985). Solomons-*- and Solomons^ data from McKeown(1977) and Vaughan (1981) respectively. Egg output per female per breedingseason is calculated as the product of mean clutch size and mean number ofclutches per breeding year. Data on Hawksbill re-nesting are very sparse;fieldwork has generally not been undertaken throughout the suspected nestperiod for the species, and only the Cousin Island (Seychelles) work, wherethere has been a resident warden to monitor year-round nesting, is based onlong-term survey data. Authors' suggested number of clutches per year aregiven for some sites outside Seychelles. Hawksbill clutches from a numberof localities (not including Seychelles) have been found to contain a numberof small yolk-less eggs.Locality Carapace length Weight Clutch Clutches Eggs/femaleof nesting (kg) size per year /breedingfemales (cm) seasonAtlanticTortuguero-*-
