Summary: The euryhaline copepod Pseudodiaptomus inopinus plays a crucial role in coastal waters by efficiently transferring DHA to larval fish, leading to enhanced growth compared to rotifers. The copepods have higher levels of DHA and EPA in their polar lipids, making them a more nutritious food source for fish larvae than rotifers. This study highlights the importance of copepods in facilitating the growth of coastal larval fish through efficient DHA transfer.

Summary: This study presents a novel gram-scale synthesis of CPP in three steps starting from pyrene. The key steps involve the ring contraction of pyrene-4,5-dione to oxoCPP in a single step, as well as the direct reduction of oxoCPP to CPP. The methodology benefits from a small number of synthetic steps, use of relatively non-hazardous reagents, and optimized purification procedures, making CPP accessible in useful quantities.

Summary: This study examines the impact of fish density and exposure duration on the bioaccumulation of trace metal elements (TME) and biomarker responses. The results show that fish density has no effect on TME accumulation in the muscle, but exposure duration significantly affects TME levels. We suggest that a 15-day exposure period with low fish density is sufficient for assessing TME pollution in the field.

Summary: This study investigates the effects of contaminants from different environmental compartments on the morphology and reproduction of the copepod Eurytemora affinis. The results show that dissolved exposures had the lowest survival rate in the first generation, while resuspended sediment exposures were more sensitive in the second generation. Different parameters were sensitive to different exposures at the individual level. The number of lipid droplets was positively correlated with trace metal bioaccumulation and negatively correlated with survival and clutch size. This study provides valuable markers for risk assessment and fish feed studies.
