Summary: This study investigated the combined effects of ocean acidification and warming on the growth and photosynthetic performance of the economically important marine macroalga Gracilariopsis lemaneiformis. The results showed that high CO2 and high temperature decreased the growth rate of the macroalga, but the high temperature may counteract the negative effects of high CO2 and improve nitrogen content.

Summary: Optimizing alkali treatment process alone is not sufficient to achieve the best agar yield and quality. Changes in algae morphology and weight, as well as the physicochemical properties of agar, need to be monitored and analyzed comprehensively during pretreatment processes. Acidification can improve yield by solving the problem of algae hardening after alkali treatment, and enzyme-assisted extraction technology shows potential to replace traditional alkali-extraction technology by promoting desulfurization efficiency and gel strength.

Summary: The use of Gracilaria chouae and Gracilariopsis lemaneiformis in aquaculture has been expanding rapidly due to their bio- and eco-functions. This study explored the carbon use mechanism of these seaweeds in different carbonate systems. It was found that high CO2 and normal HCO3- concentrations led to an increase in net photosynthetic rate and other physiological parameters in both seaweeds. Gracilariopsis lemaneiformis showed higher photosynthetic rates and pH changes. The inhibition experiments revealed different mechanisms of HCO3- utilization in these seaweeds.

Summary: This study characterized the polysaccharide from Gracilaria lemaneiformis and investigated its fermentation by rabbitfish intestinal microbes. The study found that the polysaccharide was mainly composed of galactose and anhydrogalactose, and it enhanced the production of short-chain fatty acids and altered the gut microbiota. The findings suggest that the polysaccharide has prebiotic potential and could be used as a functional feed additive in aquaculture.

Summary: This study found that selenium can alleviate the toxicity of heavy metals cadmium and copper in the red macroalga Gracilaria lemaneiformis. Low levels of selenium can reduce cadmium accumulation and alleviate the associated growth inhibition, while high levels of selenium can increase copper accumulation and induce metal chelators to alleviate growth inhibition. Selenium addition also alters metal subcellular distribution in the algae, which may affect subsequent metal trophic transfer.

Summary: The seaweed Gracilaria lemaneiformis can bioremediate heavy metals and improve the environmental quality of mariculture zones. However, the decomposition of seaweed litter produced during growth and harvest processes is rarely studied and causes secondary pollution. This study compared the decomposition rates and heavy metal release of dried and fresh Gracilaria, and found that the contacted sediments can accelerate heavy metal release from Gracilaria.

Summary: The study revealed that elevated CO2 levels led to increased growth rate and carbon concentrations in kelps, but had no effect on total nitrogen and protein contents. However, it decreased the lipid, magnesium, sodium, and calcium content and changed the amino acid and fatty acid composition. This research provides valuable insights into the metabolic response of kelps to elevated CO2 levels and the potential impact on marine trophic webs and human nutrition resources.

Summary: This study assessed the potential of seaweed cultivation in achieving carbon neutrality in China by 2060. Seaweed cultivation can remove and sequester significant amounts of carbon, nitrogen, and phosphorus, while also increasing dissolved oxygen in seawaters. Among the seaweed species studied, Gracilariopsis lemaneiformis showed the highest capacities for carbon removal and sequestration. The findings indicate that seaweed cultivation can play a crucial role in achieving carbon neutrality and mitigating deoxygenation and eutrophication in seawaters.

Summary: The two-stage model with high CO2 induction is an effective approach for the production of biodiesel and PUFA from Skeletonema costatum, suitable for both biofuel and health care markets. High CO2 levels enhance the synthesis of PUFA and increase lipid productivity, although 5% CO2 level is more beneficial compared to 10% CO2 level.

Summary: This paper reviews the changes in carbon capture and sequestration of marine primary producers and assesses the potential of different marine primary producers in carbon neutrality and climate change mitigation. Blue carbon plants are limited by available areas, while enhancing the carbon sequestration efficiency of microalgae is complex and uncertain. On the other hand, offshore cultivation of macroalgae has substantial potential due to higher carbon sequestration capacity and available areas.

Summary: Integrated multi-trophic aquaculture (IMTA) is proposed as an environmentally friendly solution for aquatic food production. However, little is known about the effects of IMTA on the growth rates and food quality of animals and plants, as well as the seasonal effects. In this study, field mesocosm experiments were conducted to investigate the impacts of IMTA on the shrimp Litopenaeus vannamei and the macroalga Ulva linza. The results showed that IMTA significantly reduced dissolved inorganic nitrogen and phosphorus levels, while increasing dissolved oxygen and pH. Furthermore, IMTA stimulated the growth rates of both shrimp and Ulva in all seasons, and improved the food quality of both species.

Summary: Aquatic ecosystems contribute 50% of global productivity and play a crucial role in mitigating climate change. Factors such as water temperature, ocean acidification, nutrient availability, deoxygenation, and exposure to UV radiation interact to either enhance or decrease productivity. While ocean warming and deoxygenation may have opposite effects on mitochondrial respiration, they synergistically affect plankton migration and N-2-fixation of diazotrophs. Ocean acidification and elevated pCO(2) have controversial effects on marine primary producers, but they can worsen viral attacks on microalgae and reduce calcification of algal calcifiers when combined with UV radiation. Field observations over a long period of time are limited, but future studies are expected to explore the responses and mechanisms to multiple drivers in different regions.

Summary: The marine picocyanobacterium Synechococcus plays a significant role in primary production in the global oceans. However, its responses to changing pCO(2) and light levels have been poorly studied. This research found that the growth of Synechococcus strain CB0101 is strongly influenced by light intensity, with peak growth at 250 μmol m(-2) s(-1). Elevated pCO(2) inhibits cell growth at high light intensities and decreases photosynthetic carbon fixation rates. It also significantly reduces particulate organic carbon and nitrogen, particularly under low light. These findings suggest that future ocean acidification may affect the growth and competitiveness of Synechococcus in surface waters.

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.
