Microalgae-based wastewater treatment has recently emerged as a promising approach for the simultaneous removal of nutrients and production of biomass. However, certain wastewater types, particularly piggery wastewater, contain high levels of ammonia that can be cytotoxic to microalgal cells. In experiments with piggery wastewater adjusted to ammonia concentrations of 45, 65, and 85 mg L-1, Chlamydomonas sp. demonstrated significantly higher removal efficiencies for ammonia and total phosphorus compared to the control medium (BG11 supplemented with equivalent ammonia nitrogen). The microalgal lipid content increased to 38.6% at 65 mg L-1 and reached 44% at 85 mg L-1, depending on the ammonia concentration. Fatty acid methyl ester analysis revealed a higher proportion of C16 : 0 (palmitic acid) at the 65 mg L-1 ammonia level, resulting in a composition favorable for biodiesel production. However, the accumulation of biodiesel-relevant fatty acids was suppressed at the excessive ammonia concentration of 85 mg L-1. In conclusion, this study underscores the metabolic adaptation and lipid regulation of Chlamydomonas sp. in high-nitrogen wastewater environments, providing a foundation for developing microalgae-based wastewater treatment and biomass valorization strategies.

Boreolithothamnion astragaloi, a coralline algal species belonging to the family Hapalidiaceae and order Hapalidiales, has been reported from British Columbia, Canada in northeastern Pacific. In this study, we report B. astragaloi for the first time from Korea, representing its initial record in the northwestern Pacific. Morpho-anatomical and molecular analyses of Lithothamnion-like specimens collected in Korea revealed that some individuals correspond to B. astragaloi. This species is characterized by flattened, flared epithallial cells; subepithallial initials as long as or longer than the cells immediately subtending them; cell fusions; multiporate tetrasporangial conceptacles; and tetra/bisporangial conceptacles developed from small groups of subepithallial initials. Phylogenetic analyses based on the COI-5P, psbA, and rbcL datasets place B. astragaloi firmly within the Boreolithothamnion clade, supporting its identification and extending the known distribution of the species to the northwestern Pacific.

This study examined the spatiotemporal distribution and community structure of fish larvae in the coastal waters of Geoje Island, Korea, from June 2024 to April 2025, and assessed the impact of environmental factors on larvae assemblages. The abundance of fish larvae varied significantly, ranging from 63 to 12,330 individuals per 1,000 m3. A total of 20 taxa from 14 families and 6 orders were identified. Dominant taxa included Clupea pallasii, Parablennius yatabei, Hexagrammos agrammus, Engraulis japonicus, Sebastiscus marmoratus, Sebastes schlegelii, Repomucenus valenciennei, and Rudarius ercodes. Cluster and nMDS analyses identified three distinct seasonal assemblages: a summer-autumn assemblage, a transitional assemblage, and a winter-spring assemblage. The summer-autumn assemblage was dominated by coastal and pelagic species, including Engraulis japonicus and Parablennius yatabei, while the winter-spring assemblage was characterized by coldseason spawning species such as Clupea pallasii and Hexagrammos agrammus. Redundancy analysis (RDA) revealed that temperature and salinity were the primary environmental drivers of fish larvae assemblages (p<0.01). Temperature was strongly correlated with Axis-1, which represents the main environmental gradient influencing larvae assemblages. Additionally, the copepod Acartia omorii showed a strong association with Axis-2, indicating that zooplankton community composition played a secondary role in shaping larvae assemblages. Environmental variables accounted for 26.3% of the total variance, suggesting that larvae distributions were affected by environmental conditions, hydrodynamic transport, spawning strategies, and biological interactions. These findings provide essential baseline information for fisheries resource management and coastal ecosystem monitoring.

This study examined the community structure of macrobenthic animals in the southern East Sea through seasonal surveys at 12 stations from November 2022 to August 2023. A total of 226 species were identified, dominated by polychaetes (102 species, 45.13%), arthropods (59 species, 26.11%), and molluscs (38 species, 16.81%). The total abundance was 1,189 ind. m-2, with polychaetes and arthropods accounting for 740 ind. m-2 (62.26%) and 266 ind. m-2 (22.36%), respectively. Biomass reached 109.93 gWWt m-2, dominated by echinoderms (38.76 gWWt m-2, 35.26%) and molluscs (33.78 gWWt m-2, 30.73%). According to the LeBris index, the top 10 dominant species accounted for 62.92% of the total individuals, including Ampelisca bocki (amphipod), Scoletoma longifolia, Sternaspis scutata, and Magelona japonica (polychaetes). Cluster analysis revealed two distinct groups in the study area: Group I, which comprised shallow stations with higher sand content and species diversity, was dominated by S. scutata, M. japonica, and Moerella hilaris. Group II included deeper stations characterized by higher mud content and lower diversity, primarily dominated by A. bocki and S. longifolia. These findings suggest that the macrobenthic community structure in the study area is largely influenced by water depth and sediment composition. Previous studies have indicated that in the southern East Sea, mud predominates, while sand content and species diversity increase towards the coast. In contrast, the central East Sea is dominated by sand, with both mud content and diversity increasing offshore. These sediment differences between the southern and central East Sea play a crucial role in shaping macrobenthic community structure.
