This study aimed to determine phylogenetic relationship between and among selected species of sea cucumbers (Echinodermata: Holothuroidea) using 16S mitochondrial ribosomal RNA (rRNA) gene. Phylogenetic analyses of 37 partial sequences of 16S mitochondrial rRNA gene using three main methods namely neighbour joining (NJ), maximum parsimony (MP) and maximum likelihood (ML) showed the presence of ...

Mariculture of tropical sea cucumbers is promising, but the nursery rearing of juveniles is a bottleneck for farming and sea ranching. We conducted four medium-scale experiments lasting 3-6 weeks, using thousands of cultured juvenile sandfish Holothuria scabra, to optimise nursery rearing in mesh enclosures in earthen seawater ponds and to test rearing in enclosures in the sea. In one experimen...

One of the ways to increase production for aquaculture is through cultivation monosexuals by ensuring genital reversal from which energy reproduction diverted towards growth. Masculinization has been identified as one most prominent techniques, where sex development was directed female male. This approach only altered phenotype and not genotype. The red claw crayfish (Cherax quadricarinatus) a ...

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 with uniqu...

Market preferences of natural resources contribute to shape their exploitation and production. Beche-de-mer, the product after gutting, cooking, salting and drying sea cucumbers, is exported worldwide to Asian dried seafood markets. A better understanding of the trade, value and market preferences of Pacific island beche-de-mer could identify critical postharvest processing techniques and manag...

introduction: sandfish (holothuria scabra) is a marine species generally sold as a raw material that has been dried even though the meat contains steroid hormone with high economic value, which has the potential to become a source of safe natural steroid hormone. this study was aimed to look at the potency of sandfish as an anti-aging for menopausal women. sandfish could become a source of natu...
