Summary: The effects of feeding rotifers and Artemia enriched with different types of enrichment on the first feeding and later stages of Scylla tranquebarica larvae were investigated. The results showed that enriched rotifers improved survival and larval development in the early stage, while digestible Tetraselmis sp. enriched Artemia enhanced survival and reduced abnormal molting in the later stages.

Summary: The use of cleaner fish, specifically ballan wrasse, is crucial for controlling sea lice in salmonid cage farming. However, large-scale cultivation of ballan wrasse faces challenges due to the difficulty of the initial feeding phase and the lack of feeding protocols. In an experiment, feeding larvae copepods as their first diet resulted in higher survival rates and better growth compared to other feeding regimes.

Summary: Blue whiting, pouting, and common dab are underutilized fish species with high sustainability potential. They were found to be valuable dietary sources of selenium, with pouting rich in iodine and mussels good sources of iodine and iron. Despite comparatively higher levels of mercury and lead in some species, the contaminants were generally of no concern in both raw materials and products. The semi-industrial products were good sources of selenium and provided appreciable amounts of calcium, iron, copper, and zinc.

Summary: The present study investigated the effects of black soldier fly larval (BSFL) meal as a fish meal (FM) replacement on the growth performance, immune responses, and resistance to Vibrio parahaemolyticus infection in Pacific white shrimp. Results showed that 5-10% BSFL meal can partially replace FM, leading to improved growth performance, decreased bacterial count, and enhanced immune parameters in shrimp.

Summary: The authors investigated the potential of portable Raman spectroscopy as a faster and more efficient method for quantifying the fatty acid composition of rotifers in aquaculture. They found that the portable instrument could accurately measure total fatty acids (TFA) and total polyunsaturated fatty acids (PUFA) and significantly reduced analysis time compared to the traditional FT-Raman system. Portable Raman spectroscopy is a promising tool for high throughput screening of rotifer lipid composition in aquaculture.

Summary: A wide range of fish species have been in public aquariums and zoological collections for more than 150 years. Although there is ongoing debate about pain perception in fish, it is widely recognized that negative impacts on their welfare can significantly affect their health and well-being. The article presents a general overview of the basic biological requirements for maintaining fish in captivity, but emphasizes the need for species-specific information and guidelines. A combination of behavioral, performance, and physiological indicators can be used to assess the well-being of these animals.

This study examined the impact of habitat degradation and restoration on underwater soundscapes and their role in larval navigation. The results showed that healthy habitat soundscapes have specific effects on larval settlement, which is diminished by habitat degradation but can be restored with appropriate restoration measures.

Summary: This study demonstrates the endogenous fatty acid metabolism of the marine rotifer, Brachionus plicatilis, and its ability to produce long-chain polyunsaturated fatty acids (LC-PUFA) from its precursors. The study also finds that the conversion rate of fatty acids is comparatively low, with a lower incorporation of docosahexaenoic acid (DHA) compared to other substrates. These factors, along with a competitive esterification pattern, may result in inadequate essential fatty acid ratios for marine larvae nutrition if not properly considered in the lipid enrichment process.

Summary: A pH-responsive clean fracturing fluid was developed based on the mechanism of pseudo-trimeric surfactant and wormlike micelles formed under specific pH conditions. The fluid can switch between high-viscosity gel state and low-viscosity aqueous solution state by adjusting pH, making it suitable for medium and low-temperature oil and gas reservoirs. After shearing for 60 minutes at 60 degrees C and 170 s(-1), the viscosity of the fluid remains higher than 500 mPamiddots.

Summary: Growing evidence suggests that microorganisms exhibit heterogeneous sensitivity to toxicants, but the mechanisms behind this remain unclear. This study confirmed the heterogenous responses of Chlamydomonas reinhardtii to Cu stress, and found a link with the cell cycle. The increase in labile Cu(I) was related to cell division, leading to fluctuations in labile Cu(I) with diurnal and cell cycles. Cu influenced the cell cycle and algae at different cell phases exhibited different Cu sensitivities. This study reveals the underlying mechanisms of heterogeneous Cu sensitivity in phytoplankton and can help assess the ecological risks of Cu.

Summary: This study quantified the nonspecific interactions between three different functional polystyrene nanoplastics and zebrafish cells. The uptake of the nanoplastics in the cells peaked within 2 hours and then decreased, and the uptake rate was similar among the different types of nanoplastics but related to their functionality. The clathrin-mediated and caveolae-mediated pathways were mainly involved in the uptake process. The internalized nanoplastics were transported to lysosomes and exocytosed by the cells via energy-dependent processes. The estimated retention half-lives of the nanoplastics in fish cells were also determined.

The results showed that the diet composition of threadfin fish varied with their size and ontogeny, and it also shared food resources with other co-existing fish species. Additionally, the size, sex, and collection location of the fish significantly affected their gut fullness index and the number of food types they consumed.

Summary: Due to the COVID-19 pandemic, billions of people wear face masks daily, but the potential risks of hazardous materials released from these masks remain largely unexplored. This study evaluates the leachability and cytotoxicity of copper nanoparticles in face masks for the first time. The results show that inhalation of copper from the mask accounts for around 3% of the total copper, and a significant amount of copper attached to the fibers can be easily released into solution. The released copper causes cellular stress and oxidative damage. These findings underscore the need for careful assessment of the leaching of nanoparticles in face masks.

The results revealed that the gills and digestive gland were the main sites for copper exchange and storage. The gills played a crucial role in regulating copper levels and removing copper from water, while the digestive gland facilitated copper absorption. These findings enhance our understanding of homeostatic regulation and transportation mechanisms in marine bivalves.

The results showed that the transformation products exhibited varied estrogenicity, with oxybenzone transformation products displaying greater estrogenicity than the parent compound at certain reaction times. The findings highlight the importance of considering mixtures and post-transformation cocktails in chemical testing and risk assessment to better evaluate the potential risks associated with these compounds.

Summary: A two-compartmental toxicokinetic model is used to explain the interspecies sensitivity of imidacloprid to different aquatic invertebrates by distinguishing relevant levels of toxicity in organisms. The sensitivity to imidacloprid can vary significantly among different species. Internal levels of toxicity and toxicokinetic parameters are essential in understanding interspecies sensitivity. The model demonstrates that imidacloprid exhibits the highest toxicity to Chironomus dilutus, followed by Lumbriculus variegatus, Hyalella azteca, and Daphnia magna. The sensitivity of these invertebrates to imidacloprid varies by over 1000 times based on water concentrations, but decreases to around 50 times when based on internal residues, highlighting the importance of toxicokinetics in interspecies sensitivity. The two-compartmental model successfully simulates the slow elimination of imidacloprid in three species by distinguishing dynamic and toxicologically available fractions.
