“…Also, a study in the intertidal zone of Aurora, Philippines, revealed that H. scabra and Stichopus sp. are present in the area, but their density is critical for repopulation (15) . Furthermore, Sandfish (Holothuria scabra) was classified under the "Endangered" list of the International Union for Conservation of Nature and Natural Resources (IUCN) (29) .…”

Objective: To determine the catch and trade of sea cucumbers in Nasingin, Getafe, Bohol. Methods: The study utilized a descriptive survey method using a structured questionnaire to gather information from the respondents. Respondents were taken using the snowball sampling method. All the fresh samples were weighed and identified based on their genus and species level using the field guides at the landing sites for two months sampling period. Moreover, catch per unit effort (CPUE) was obtained per catching method, and then a significant difference among them was determined. Findings: Results revealed that there were seventeen (17) identified species of sea cucumber. Out of the seventeen ( 17) recorded species in this study, five (5) species were regarded in a similar study as highly exploited species. Moreover, one (1) species recorded in the survey was just classified under the "Endangered" list of the International Union for Conservation of Nature and Natural Resources (IUCN). In terms of the catching method, respondents employed: compressor fishing, gleaning, skin diving, and by-catch using beach seine and triple net. It was also shown that compressor use attained the highest CPUE at 1.74 kg/hr. for April and 2.01 kg/hr. for May and triple net during daytime gained the least CPUE at 0 kg/hr. for April and 0.28 kg/hr. for May. Moreover, it was found that more fishers preferred to dispose of their caught sea cucumber fresh by size and or by species to the local assemblers rather than selling it dried or processed. Novelty: It is noteworthy that some sea cucumber species recorded in this study are still caught and traded despite their listing in IUCN as "endangered" and in CITES Appendix II.

“…Moreover, according to the recent data from FAO (2019), only Indonesia and the Philippines have been consistent and active in sea cucumbers' fishery since 1950 (14) . Further, sea cucumber collection is a livelihood activity for coastal communities in the Philippines (15).…”

“…However, the skyrocketing demand for these species causes the collection of the species to be conducted in deeper waters. As a result, the Philippines ranked second in production and export in the world, next to Indonesia, with 20,000 tons of catch per year (Cañada et al 2020). There are more than 1500 different species of sea cucumber, and about 100 species are recognized to be safe for human consumption.…”

Abstract. Ereguero MG, Cordero MA, Dalayap R, Tabugo SR. 2022. Antifungal activity of selected sea cucumber species from Tukuran, Zamboanga del Sur, Mindanao, Philippines using modified SPOTi assay. Biodiversitas 23: 6049-6055. Marine organisms have become essential candidates for discovering novel compounds that can be medically and commercially important. They are believed to yield novel compounds with unique chemical structures and significant biological activities since they managed to survive a milieu of pathogenic microorganisms and essential predators. The quest against fungal infections has been challenging due to acquired resistance to commercially available drugs hence, novel sources to treat infectious diseases caused by fungi have been investigated. Sea cucumbers have been recognized in Asian countries as a rich food source. Apart from that, they have also been studied for their medicinal properties. This study aimed to evaluate the antifungal activity of the selected sea cucumber species found in Brgy. Sugod, Tukuran, Zamboanga del Sur, Mindanao, Philippines using the modified SPOTi assay. Methanol: ethyl acetate crude extracts of Holothuria scabra, Stichopus sp., and Holothuria atra were tested for their antifungal activity against Aspergillus niger and Candida tropicalis. A 96-well plate assay was used, and the growth of fungi was assessed visually for up to 72hrs. The concentration resulting in ‘no fungal growth’ was observed and taken as the Minimum Inhibitory Concentration (MIC) value. The average MIC was calculated. Results showed that sea cucumber crude extracts have MIC values of 0.0333-0.1 mg/mL. Tukey’s posthoc test confirmed that the antifungal activity of the sea cucumber extracts was comparable to the positive control Fluconazole (p>0.05). The present study revealed a potentially effective natural antifungal agent from sea cucumbers.
