may be harder to catch because they are not approaching and departing from nesting beaches, nor<br />

are they mating at the water's surface. Thus, during the season when pelagic fish such as flying<br />

fish (Hirundichthys affinis) and dolphin fish (Coryphaena hippurus) become abundant, fishermen<br />

concentrate on this more profitable fishery rather than on sea turtles.<br />

Very few fishermen, if any, are dependent on the turtle fishery <strong>for</strong> their primary<br />

livelihood. No reliable records of turtle landings at fish markets have ever been kept, again<br />

suggesting that the turtle fishery was never considered important. At the present time, the<br />

majority of turtles are probably captured illegally whilst laying eggs on the beach. Certainly a<br />

high proportion of hawksbills observed nesting by the public is killed annually (15-22%, section<br />

2.4). Consistent with a lack of economic dependence of Barbadians on sea turtles, there is a<br />

general lack of superstitions or traditions associated with sea turtles when compared to other<br />

islands in the region. This lack of dependence, combined with the high literacy rate in <strong>Barbados</strong>,<br />

may make conservation of sea turtles in <strong>Barbados</strong> relatively easier than in some other parts of the<br />

region.<br />

II. STATUS AND DISTRIBUTION OF SEA TURTLES IN BARBADOS<br />

2.1 Caretta caretta, Loggerhead <strong>Sea</strong> <strong>Turtle</strong><br />

There are no indigenous common names applied to this species and the preferred name is<br />

loggerhead. The loggerhead turtle is recognized by its large head, thick, somewhat tapered<br />

carapace (=shell), brown and gold or reddish-brown colouration, and characteristically heavy<br />

encrustation of invertebrate epifauna (especially barnacles). There are typically five pairs of<br />

lateral scutes on the carapace (Figure 1). The large head and strong jaws, <strong>for</strong> which the species<br />

was named, are necessary adaptations to a diet of mollusks and hard-shelled crabs; tunicates,<br />

fishes, and plants are also eaten (Dodd, 1988). Adults attain a straight-line carapace length of<br />

120 cm (nuchal notch to posterior tip) and weigh up to 200 kg (Pritchard et al., 1983).<br />

The species has a wide oceanic distribution. In the Atlantic Ocean individuals have been<br />

sighted as far north as Newfoundland (Squires, 1954) and northern Europe (Brongersma, 1972)<br />

and as far south as Argentina (Frazier, 1984). Nesting grounds are often located in temperate<br />

latitudes, with the greatest numbers of nesting females recorded on the Atlantic coast of Florida<br />

(USA) and on the shores of Masirah Island, Oman. Nesting is also reported from various islands<br />

of the Greater and Lesser Antilles (although firm records are not always available), the<br />

Caribbean coasts of Mexico and Central America, and the Atlantic coast of South America from<br />

Venezuela to Brazil, as summarized by Dodd (1988).<br />

Loggerheads are not known to nest in <strong>Barbados</strong>, but juveniles (one weighed 32 kg) and<br />

adults or near-adults (one measured 83 cm straight carapace length) are occasionally caught<br />

opportunistically offshore by pelagic fishermen. These turtles are usually speared by the<br />

fishermen as they wait <strong>for</strong> their gill nets to fill (see section I). The meat is eaten whenever<br />

available. Foraging grounds have not been identified. Neither spatial nor temporal patterns of<br />

distribution are known. Population estimates are not available. The species is considerably rarer<br />

than either the green turtle or the hawksbill.<br />
