Summary: This study investigated the abundances and characteristics of microplastics in sediments and sandfish in Lampung and Sumbawa, Indonesia, finding a high abundance of microplastics in both sandfish and sediments. The results suggest the need for improved solid waste management in Indonesia to reduce the sources of microplastics.

Summary: In order to sustainably promote the development of wild sea cucumber fisheries, management strategies including restocking and sea ranching programs have been implemented. Genetic analysis reveals that wild populations have high genetic diversity and gene flow, while hatchery-produced individuals suffer from genetic drift and small effective population size.

Summary: Sea cucumber hydrolysate with UV-B protective and antioxidant activities was prepared using three commercial enzymes. The optimum conditions for hydrolysis were determined and the resulting hydrolysates showed high degree of hydrolysis, yield, and antioxidant activities. Additionally, six potential peptides were identified from the selected hydrolysate.

Summary: The sea cucumber Holothuria scabra is an economically important species and an emerging experimental model for research studies in regeneration and medicinal bioactives. Identification and expression analysis of growth factor genes in H. scabra provided molecular information of growth factors in this species. Genes such as BMP 2A, BMP5-like, NT, and FGF18 were found to be widely expressed in various tissues, with specific localization patterns.

Summary: Intraspecific chemical communication in sea cucumbers has been observed not only during spawning, but also throughout the year. This study investigates the aggregation behavior and chemical communication of the sea cucumber Holothuria scabra. The study confirms that the sediment and water preconditioned by conspecifics induce positive chemotaxis in juvenile individuals, and identifies a distinct saponin profile as a pheromone for sea cucumber intraspecific recognition and aggregation.

Summary: Hatcheries are crucial for seed production in commercial aquaculture species, but they can lead to loss of genetic diversity among progeny. By analyzing genome-wide SNPs, this study evaluated the genetic impacts of hatchery production on sandfish, a high-value sea cucumber. The results showed skewed parental contributions, low effective population sizes among offspring cohorts, and a need for optimizing hatchery protocols to ensure genetically diverse offspring.

Summary: The study in the Tigak Islands of Papua New Guinea found that the recovery rate of cultured juvenile sea cucumbers was low, mainly due to factors such as mortality, migration, and the misidentification of cultured and wild individuals. The species richness and density of the wild sea cucumber community increased in response to stocking and protecting the sea ranch.

Summary: The sandfish Holothuria scabra is a valuable tropical sea cucumber species for mariculture in the Indo-Pacific region. Genomic technologies have the potential to improve mariculture production by enhancing growth traits. By analyzing the transcriptome of fast- and slow-growing sandfish from the Philippines, this study identified genes associated with immune response and metabolism in fast-growing individuals, as well as genetic markers linked to fast growth. These findings offer insights into the genetic factors regulating growth in juvenile sandfish and can guide future functional studies.

Summary: Oyster farming is an important industry in both developed and developing countries, but overexploitation of natural stocks has caused declines in spat fall and unstable production. This study compared the growth and survival of wild and hatchery-bred oyster spat and found that they had similar growth rates and survival rates in grow-out culture, indicating the potential of hatchery-bred oyster spat as seeds for addressing the declining number of spat fall in natural oyster beds.

Summary: Abalone, particularly the Haliotis asinina species, is an important and highly studied fishery resource in the Philippines. The traditional reliance on Gracilariopsis heteroclada as food for abalone is not sustainable, prompting the investigation of alternative food sources like Ulva reticulata. However, the study found that while Ulva reticulata is not a suitable sole substitute for Gracilariopsis heteroclada, its potential as a partial substitute warrants further exploration.

Summary: The rapid global spread of COVID-19 and other anthropogenic threats such as global climate change are posing significant economic challenges to the aquaculture sector. A positive correlation between the impacts of the pandemic and anthropogenic stressors was detected, with different effects on various parts of the supply chain. The use of integrated multitrophic aquaculture (IMTA) methods may enhance resilience to multiple stressors, providing different market options during the COVID-19 pandemic.

Summary: Farmed eucheumatoids are the top aquaculture commodity in the Philippines, but have suffered significant production losses in recent years due to pests and diseases. The study found ice-ice disease to be widespread across all sites, although prevalence rates were generally low. Further strategies for diagnosis, surveillance, and management are needed to ensure the sustainable development of this important aquaculture sector in the Philippines.

Summary: Settlement of sea cucumbers is a critical phase in larval development, and the highest mortality occurs during this stage. This study evaluated the potential of Chaetoceros calcitrans concentrate as a settlement cue for H. scabra larvae. The results showed that the settlement efficacy of the concentrate was comparable to that of commercial 'Spirulina' and live benthic diatoms.

Summary: This study compared the effects of feeding abalone with seaweed, formulated diet, or a mix of both. The results showed that abalone fed mixed diets had the highest growth rates, shell length, and body weight. Survival rates were also higher in abalone fed mixed diets. The findings highlight the importance of a balanced and more nutritional diet for the well-being of abalone.

Summary: Molluscs are a valuable resource in the Philippines, providing food and livelihood for marginalized fisherfolk. However, mollusc culture has remained small-scale and dependent on wild seed stocks. The lack of commercial-scale hatcheries and limited government support hinders large-scale production. Future research should focus on refining technologies and addressing gaps in economic viability, post-harvest technologies, and genetic information for mollusc culture.
