Short Communication:  Antimicrobial properties in cloacal fluid of olive ridley sea turtle (Lepidochelys olivacea)

Abstract. Praja RN, Yudhana A, Haditanojo W, Oktaviana V. 2021. Short Communication: Antimicrobial properties in cloacal fluid of olive ridley sea turtle (Lepidochelys olivacea). Biodiversitas 22: 3671-3676. There were several speculations regarding the main purpose of sea turtle cloacal fluid, such as lubrication during egg deposition, which could help reduce egg speed as they are dropped in nesting sand, or contain antimicrobial properties to protect their eggs from pathogenic microorganisms. However, the exact purpose of this fluid which is mucous-like in consistency remains unknown. This study aimed to identify antimicrobial properties in the cloacal fluid of olive ridley sea turtles. Cloacal fluid samples were collected during nesting season in Banyuwangi City coastal areas, East Java Province, Indonesia. Moreover, the Kirby-Bauer diffusion disk method recorded antimicrobial properties and tested against several bacterial colonies collected from sand in natural nesting chambers. This preliminary study also concluded that antimicrobial properties were recorded when presented against several bacteria colonies from natural nesting sands namely Escherichia coli, Salmonella spp., and Bacillus spp. Furthermore, the present study should be expanded to include other bacteria and fungi colonies. In addition, results from the present study could be used to develop methods in creating antibiotics similar to those found naturally in natural nesting areas to prevent microorganism contamination and globally increase hatchling success, which has a greater impact to support sea turtle conservation efforts as endangered species.

According to observation and interview that undertaken in Panga District Aceh Jaya Regency that there are 3 species of sea turtle with coastal line is 9.3. km. The third of such sea turtle including Olive ridley sea turtle(Lepidochelys olivacea), hawkbill sea turtle (Eremochelys imbricate), leatherback sea turtle (Dermochelys coriacea). The target of community that involved in socialization of sea turtle are student of junior high school. Earlier education to young generation regarding the important of sea turtle conservation educated-based is the effort for keeping sea turtle in natural with undertook the socialization to young generation in order to grow a caring and loving to sea turtle sustainablity. Coastal community still undertook to hunting sea turtle’s eggs for trading in the traditional market dan restaurants. It is caused by lack of understanding and awareness regarding sea turtle that threaten scarce. In this activity, the researcher will undertake persuasive approaach and solutive in changing a mindset of young generation gradually that inhabit in near nesting site. In this activity including suvey activity prior to socialization that near the nesting site, socialization activity in the SMPN 1 Panga that selected as target school in the socialization of Sea Turtle Conservation, conducting the retelling story games, and conducting hatchlings release programme to the sea with community elements.

This article presents biological data and an assessment of the conservation of the olive ridley sea turtle (Lepidochelys olivacea) population nesting in the States of Sergipe and Bahia, north-eastern Brazil, between 1991/1992 and 2002/2003. Projeto TAMAR-IBAMA (the Brazilian Sea Turtle Conservation Programme) maintains seven field stations in that region to monitor nesting activity over 339 km of beach. An increasing trend was observed in the estimated number of nests per nesting season: from 252 nests in 1991/1992 to 2606 in 2002/2003, an approximately 10-fold increase in 11 years. The available data and biological knowledge suggest that TAMAR's conservation efforts may have contributed to the significant increase in olive ridley nesting in Sergipe and Bahia; that increase is not only of regional importance, but also of significance at the western Atlantic level.

Taman Kili-Kili Beach is designated as an Essential Ecosystem Area (KEE). 188/39/KPTS/013/2020. According to the Supervisory Community Group (Pokmaswas), in 2011-2020, there was an increase in broodstock as many as 52 turtles, and the eggs saved as many as 3323 eggs. However, since 2013 Pokmaswas data shows a decrease in the population of hawksbill and green turtles in turtle conservation areas, which is thought to be caused by climate change, global warming, and animals. This study aims to analyze environmental baselines, turtle populations, and the value of turtle ecotourism (ecological, economic values) and develop strategies to support turtle conservation at Taman Kili-Kili Beach Trenggalek Regency. The results of the adjustment of nesting habitats and turtle ecotourism, calculation of the Habitat Conformity Index (IKH) of turtle nesting, IKH = 77.77%, which belongs to the category (S1) is very suitable to be used as a conservation area and turtle nesting habitat. While the results of the calculation of the Turtle Ecotourism Conformity Index (IKW), IKW = 84.93%, which is included in the (S1) category, which is very suitable for use a turtle tourism area. The strategy for developing turtle ecotourism is in quadrant II, meaning that it utilizes the strengths possessed in the turtle conservation area by minimizing the threats that it will experience.

Long Time

Marine mammals such as whales and dolphins have been known for a long time to host a very specific epizoic community on their skin. Less known however is the presence of a similar community on the carapaces of sea turtles. The present study is the first describing new taxa inhabiting sea turtle carapaces. Samples, collected from nesting olive ridley sea turtles (Lepidochelys olivacea) on Ostional Beach (Costa Rica), were studied using light and scanning electron microscopy. Two unknown small-celled gomphonemoid taxa were analysed in more detail and are described as two new genera, closely related to other gomphonemoid genera with septate girdle bands, such as Tripterion, Cuneolus and Gomphoseptatum. Chelonicola Majewska, De Stefano & Van de Vijver gen. nov. has a flat valve face, uniseriate striae composed of more than three areolae, simple external raphe endings, internally a siliceous flap over the proximal raphe endings and lives on mucilaginous stalks. Poulinea Majewska, De Stefano & Van de Vijver gen. nov. has at least one concave valve, uniseriate striae composed of only two elongated areolae, external distal raphe endings covered by thickened siliceous flaps and lives attached to the substrate by a mucilaginous pad. Chelonicola costaricensis Majewska, De Stefano & Van de Vijver sp. nov. and Poulinea lepidochelicola Majewska, De Stefano & Van de Vijver sp. nov. can be separated based on stria structure, girdle structure composed of more than 10 copulae, raphe structure and general valve outline. A cladistics analysis of putative members of the Rhoicospheniaceae indicates that the family is polyphyletic. Chelonicola and Poulinea are sister taxa, and form a monophyletic group with Cuneolus and Tripterion, but are not closely related to Rhoicosphenia, or other genera previously assigned to this family. Features used to help diagnose the family such as symmetry and presence of septa and pseudosepta are homoplastic across the raphid diatom tree of life.

This paper considers fisheries bycatch reduction within the least-cost biodiversity impact mitigation hierarchy. It introduces conservatory offsets that are implemented earlier in the biodiversity impact mitigation hierarchy than conventional compensatory offsets used as instruments of last resort. The paper illustrates implementation in an on-going sea turtle conservation programme by the International Seafood Sustainability Foundation.
