Deposit-feeding invertebrates are proposed bioremediators in microbial-driven sediment-based aquaculture effluent treatment systems. We elucidate the role of the sediment reduction-oxidation (redox) regime in structuring benthic bacterial communities, having direct implications for bioremediation potential and deposit-feeder nutrition. The sea cucumber Holothuria scabra was cultured on sediment...

Cardiovascular disease (CVD) is among the leading causes of death in world caused by thrombosis. Thrombosis formation excessive blood clots on walls vessels called thrombus. This could lead to fatal blockage heart muscle or brain. can be treated using enzyme-type drugs such as thrombolytic proteases. There have been many studies bacteria producing enzymes isolated from fermented foodstuffs. How...

The co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or 'sandfish', with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in tanks with enriched sand substratum. Feed was supplied on trays, accessible only to shrimp. Survival of shrimp and sandfish was high in all treatments (73–100%). Growth of shrimp...

Predation and competition are among the most important factors affecting sandfish, Holothuria scabra, growth survival in ocean-based production systems. In this study, potential predators competitors of sandfish juveniles reared at two sites Philippines using floating hapa ocean nursery system were assessed. A total 26 species from 16 different families fishes, molluscs crustaceans recorded. Th...

Sea cucumber is rich in protein that can be used to prepare a potential derived bioactive peptide for antioxidant and protective effect against UV-B induced skin cell damage. This study aimed optimize preparation of sea hydrolysate with both activities using three commercial enzymes response surface methodology (RSM) face-centered central composite design (face- centered CCD). Hydrolysis time c...

Animal welfare during handling and transportation to aquaculture facilities or public aquaria is commonly estimated by addressing injury andmortality levels. Although these procedures have been optimized for different species, data on individual species’ cellular capabilities to tolerate stress are still scarce. In the present study, several biomarkers related with oxidative stress and energy m...
