Turtles are one of the reptile animals that can migrate long distances along the Indian Ocean, Pacific Ocean and Southeast Asia. The purpose of turtle migration is to mate, find spawning locations and to find food. Sea turtles have an important role in maintaining the balance of the marine ecosystem. However, the high utilization of sea turtles by humans causes the turtle population to decline. One of the conservation sites that help the government program is in Serangan, Denpasar Bali, namely the TCEC (Turtle Conservation and Education Center), where there are several types of turtles such as the lekang turtle, hawksbill and green turtle. Data collection techniques in this study used observation methods including beach monitoring, relocation of turtle eggs to semi-natural hatchery hatching, hatchling and turtle nesting as well as measurement of turtle length and width carapase curve (CCL/CCW), sand temperature, nest depth, nest diameter, nest distance and nest calculation of the number of eggs to see the success of hatching. The results are turtle conservation activities, ranging from turtle maintenance, hatching of turtle eggs, relocation of eggs, and maintenance of hatchlings to release turtles. The effectiveness given by TCEC to manage and preserve the existence of sea turtles in Indonesia, especially in the Bali region is to provide awareness to the community by not consuming eggs and turtle meat.

Leatherback (Dermochelys coriacea) and green (Chelonia mydas) sea turtles in Suriname lay eggs over several months of the year. During this nesting season, changes in rainfall produce changes in sand temperature, which in turn influence the sexual differentiation of incubating sea turtle embryos. The overall sex ratio of leatherback and green sea turtle hatchlings produced at Matapica beach in Suriname was investigated. Estimates of the sex ratios of these turtles in 1993 (green turtles 63.8% female, leatherbacks 69.4% female) were roughly 10% more female-biased than those from an earlier study in 1982. For both species, a significant negative relationship was found between monthly rainfall and monthly sex ratios. Using this relationship and data on rainfall in the past, it was possible to estimate overall sex ratios for an additional 12 years. These estimates varied considerably among different years, ranging from 20 to 90% female in the case of green turtles. Nevertheless, males tended to be produced primarily in April and May, while some females were produced in all months. Such seasonal patterns of production of turtles of different sexes have implications for sea turtle conservation programs that involve manipulating or harvesting eggs.

All species of sea turtles are globally endangered, largely due to the impact of unsustainable tourism. Gili Trawangan, a small island, depends on marine tourism and has an abundant population of sea turtles. Stakeholder collaboration is often used to promote sustainable tourism development and sea turtle conservation. This study examined stakeholder collaboration to promote conservation in sea turtle tourism in small islands by exploring a case study in Gili Trawangan, Indonesia. The study was conducted in 2010. It applied qualitative research methods to expand the knowledge of collaboration in the development of sustainable tourism in small islands. Stakeholder analysis helped to reveal barriers to and influences on tourism development to help promote sea turtle conservation and protect the livelihoods of local communities. Key findings are that education, financial considerations, management structure, regulatory conflict, a disconnect to the island, and stakeholder conflict are factors that influenced stakeholder collaboration in Gili Trawangan.

Turtle Population

The conservation of sea turtles in a nature-based tourism area is significant to enhance sustainability of the sea turtle population in the wild. Small islands in Lombok Island chains, the Gili Matra, are one of the significant habitats for turtles, and the island is recognized as one of the islands with fastest tourism growth in Indonesia. The research aims to explore the stakeholders’ perspectives in sea turtle conservation in Gili Matra, Lombok. Focus group discussion was implemented to identify the stakeholder perspective. Literature survey was carried out to generate related data concerning sea turtle population and its habitat quality in Gili Matra. The result of this study indicates that stakeholders can identify three species of sea turtle in Gili Matra waters, namely the green sea turtle (Chelonia mydas), the Hawksbill Turtle (Eretmochelys imbricate), and the ridley sea turtle (Lepydochely olivacea). Stakeholders state that between 1990 and 2017, there was reduction in the population size in Gili Matra. Factors related to the decrease of population in Gili Matra include decrease of habitat quality and human activity. Some recommendations were made, including increasing socialization and campaign, providing tools and facility to support conservation action, controlling unsustainable practice of fish collection, strengthening the implementation of regulation, and providing training and technical assistance to the local community and local office.

AbstractThe Brazilian Sea Turtle Conservation Programme (TAMAR) was established in 1980 to protect sea turtles in Brazil and to re-establish their natural life cycle, which had been disrupted by humans. The programme is based on grassroots involvement by the coastal communities, and provides jobs and generates alternative sources of income. Within this framework, the mini-guides programme was created. It consists of a summer training course in which local children between 8 and 13 years old learn basic information about marine ecosystems and sea turtles, strategies to promote their conservation, and skills to interact effectively with tourists. After the course, children are given onsite experience by working as interns at the TAMAR visitor centre at Praia do Forte, on schedules designed to avoid conflicts with their studies at school. The children work closely with tourists, informing them about sea turtles and TAMAR's work; they also help the biologists in field activities. In this way, they enhance their own awareness, and by extension their families' and the community's concern about environmental conservation. Their involvement provides them not only with valuable skills, but also an extra source of income, thereby providing economic benefits to their families. The success of this programme is indicated by the excellent approval ratings given by the tourists visiting the area.

Sea turtle undertaken a process of egg laying in once that yield almost hundreds eggs. Meanwhile, the eggs can be alive only several eggs. According to IUCN (International Union Conservation of Nature and Natural Reserve) in 1963 stated that such condition that caused a number of population is decreased. The target of community that involved in the technical guidance regarding egg sea turtle relocation namely undergraduate student of fisheries and marine science faculty, University of Teuku Umar. According to survey and interview that coastal community still undertook to hunting sea turtle’s eggs for trading in the traditional market dan restaurants. The priority problem that face in coastal community dinamic especially Panga Pasie area. for instance, eggs hunting that caused economical problem in order to can be survive in life. In other hand, the exploitation action cause reducing sea turtle population drastically in nature. Thus, if nobody care to effort of sea turtle conservation that undertook by stakeholder so, it occured a scarcity of sea turrtle that already enter in redlist IUCN category. It is caused  disturbance of environment and marine biodiversity in balance a marine ecology. The technical guidance including survey of nesting site, sosialization of sea turtle properties, focus group discussion (FGD) and tecnique of sea turtle eggs relocation. Overall activity of community serving that undergo on time and get a supporting from udergraduate student.

Abstract Hybridization between sea turtle species occurs with particularly high frequency at two adjacent nesting areas in northeastern Brazil. To understand the outcomes of hybridization and their consequences for sea turtle conservation, we need to evaluate the extent of hybridization occurrence and possible deleterious effects in the hybrid progeny. Thus, we investigated the hypothesis of the existence of a new hybrid spot offshore of Brazil’s northeastern coast. The Abrolhos Archipelago is surrounded by the largest and richest coral reefs in the South Atlantic and is known to be a nesting site for loggerhead turtles (Carettacaretta). In this study, we performed a multidisciplinary investigation into levels of hybridization in sea turtles and their reproductive output in the Abrolhos beaches. Genetic data from mitochondrial DNA (mtDNA) and six autosomal markers showed that there are first-generation hybrid females nesting in Abrolhos, resulting from crossings between hawksbill males (Eretmochelysimbricata) and loggerhead females, and backcrossed hatchlings from both parental species. The type and extent of hybridization were characterized using genomic data obtained with the 3RAD method, which confirmed backcrossing between F1 hybrids and loggerhead turtles. The reproductive output data of Abrolhos nests suggests a disadvantage of hybrids when compared to loggerheads. For the first time, we have shown the association between hybridization and low reproductive success, which may represent a threat to sea turtle conservation.
