<strong>Barbados</strong> <strong>Sea</strong> <strong>Turtle</strong>s …<br />
Hawksbills are "spongivores" feeding on reef-associated sponges in the Caribbean<br />
region. Sponges contributed 95.3% of the total dry mass of all food items in digestive tract<br />
samples from 61 animals from seven Caribbean countries (Meylan, 1988). Specific feeding<br />
areas have not been identified in <strong>Barbados</strong>, but <strong>for</strong>aging is assumed to be more or less coincident<br />
with the distribution of coral reefs around the island (section 4.111). All size classes 23 cm<br />
straightline carapace length and larger are seen in <strong>Barbados</strong>' nearshore waters. The turtle fishery<br />
concentrates its ef<strong>for</strong>ts within the nesting season (May-October). At this time, entangling nets<br />
(20-30 cm mesh) typically 2.5-3.5 m deep and 20-150 m long are set close to shore where<br />
females are likely to be approaching and leaving beaches. Nets set within 100 yds of shore are<br />
illegal, but en<strong>for</strong>cement is problematic (sections 4.21, 4.22).<br />
The illegal killing of nesting hawksbills remains a problem, primarily because the penalty<br />
(Bds. $100) is insufficient and en<strong>for</strong>cement of the present legislation is difficult. In 1987, 22%<br />
of nestings reported by the general public resulted in the female being slaughtered. In addition,<br />
poaching of eggs occurred in approximately 15.2% of all reported nestings. In 1991, Bellairs<br />
Research Institute received in<strong>for</strong>mation on nesting by a total of fewer than 50 different turtles,<br />
and eight of these animals (>16%) were slaughtered. The habit of nesting on the highly<br />
developed west and south coast beaches has meant that hawksbills are also adversely affected by<br />
coastal development and beach erosion (see section 3.1). Jewelry and other items made from<br />
hawksbill shell are widely available in tourist-oriented shops and there is some export of shell to<br />
Japan (section 3.3).<br />
2.5 Lepidochelys kempii, Kemp's Ridley <strong>Sea</strong> <strong>Turtle</strong><br />
There are no records of Kemp's ridleys <strong>for</strong>aging or nesting in <strong>Barbados</strong>, nor would the<br />
species be expected to occur. With the exception of a single recapture from Caribbean<br />
Nicaragua of a "head-started" individual (Manzella et al., 1991), which may have displayed<br />
altered behavior due to having been held captive during its first year (Woody, 1991), Kemp's<br />
ridleys are confined to the Gulf of Mexico and temperate northern Atlantic. Unarguably the<br />
most endangered sea turtle in the world, the total adult population is thought to number no more<br />
than 900 females and an unknown number of males (Ross et al., 1989). Some 42,000 females<br />
were observed nesting in a single day at the primary rookery at Rancho Nuevo in 1947, whereas<br />
200-400 females nest annually today (Richard Byles, U. S. Fish and Wildlife Service, pers.<br />
comm.). The species nests almost exclusively in the state of Tamaulipas, Mexico.<br />
2.6 Lepidochelys olivacea, Olive Ridley <strong>Sea</strong> <strong>Turtle</strong><br />
There are no records of olive ridleys <strong>for</strong>aging or nesting in <strong>Barbados</strong>. However,<br />
occasional individuals may be expected in view of the occurrence of this species in Trinidad and<br />
Suriname. In the Western Atlantic, significant levels of nesting appear to occur only in<br />
Suriname, primarily at Eilanti Beach (Schulz, 1975). Olive ridleys nesting in Suriname have<br />
declined considerably in recent years, dropping from about 3,000 nests per year in the late 1960's<br />
to fewer than 500 nests per year today (Fretey, 1990). Diffuse nesting occurs in northwestern<br />
Guyana and in French Guiana (Reichart, 1989).<br />
