Summary: High concentrations of NH3-N suppress rotifer growth and reproduction, with tropical rotifers showing higher tolerance to ammonia exposure and more active anti-stress strategies compared to temperate rotifers. The findings suggest specific ammonia sensitivity between tropical and temperate rotifer species, with the tropical species exhibiting stronger ammonia tolerance, supporting high-density endurance during mass culture.

Summary: This study investigates the tolerance, reproduction, behavior, and mitochondria-mediated stress and energy defenses of two species of rotifers, Brachionus plicatilis and Brachionus rotundiformis, following zinc chloride exposure. The results show that higher concentrations of zinc chloride inhibited reproductive processes in B. plicatilis but stimulated sexual reproduction in B. rotundiformis. The two species also exhibited different metabolic patterns and behavioral responses to zinc exposure.

Summary: In this study, the impact of salinity and temperature on the marine tropical rotifer Brachionus rotundiformis was evaluated through life cycle parameters, fatty acid composition, and gene transcription levels. The findings suggest that changes in culture conditions influenced the reproduction and fatty acid concentrations of B. rotundiformis. Additionally, the transcriptional levels of Elovl and Fad genes were observed to be associated with compositional modulations of fatty acids, with Elovl9b potentially serving as a useful biomarker due to its temperature-dependent modulation.

Summary: The study revealed that iron had a significant impact on the reproductive patterns of the temperate species Brachionus plicatilis, while it promoted population growth and extended lifespan in the tropical species Brachionus rotundiformis. Additionally, Brachionus rotundiformis demonstrated a better antioxidant mechanism and upregulation of genes related to lipid synthesis and reproduction when exposed to iron, suggesting higher resilience to iron-induced oxidative stress compared to Brachionus plicatilis.

Summary: The study investigated the spawning migration and habitat utilization of greater amberjack in the East China Sea. The fish were found to mainly stay in the waters off eastern Taiwan in winter, then migrate southward in spring to experience a slowly elevated water temperature regime before spawning. This behavior may be influenced by oceanographic features like the seasonal monsoon and the Kuroshio.

Summary: In this study, the entire complement of typical homeobox (Hox) genes in three representative copepods was identified and compared. The Hox gene expression patterns varied among different developmental stages, with some genes mainly expressed in early stages while others mainly expressed in later stages. This suggests that Hox genes may play a crucial role in segment identity development during early development.

Summary: We evaluated the impact of bearing tetrodotoxin (TTX) on salinity stress in juvenile tiger puffer Takifugu rubripes. The study showed that rearing TTX-containing tiger puffer in low salinity resulted in lower survival rate and body weight, while high salinity led to higher plasma osmolality and cortisol levels.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
