Summary: This study investigates the effects of temperature on the fertility and growth of the kelp species Laminaria digitata. It finds that there are persistent effects of temperature on gametogenesis and recruitment within the gametophyte generation, and a cold pre-experimental cultivation enhances the growth and thermal tolerance of juvenile sporophytes. This cross-generational effect suggests that priming of early life cycle stages can increase the resilience and productivity of kelps in marine forest restoration and kelp mariculture.

Summary: In this study, we examined the fragmentation and attachment mechanisms in sea-based cultivation of Asparagopsis armata. The results showed that fragments attached to substrata using specialized barbs and were able to regrow. These findings have important implications for large-scale cultivation.

Summary: This study examined the effect of different binder types and application treatments on the adhesion of kelp propagules to cultivation ropes, and evaluated their effectiveness by comparing adhesion densities under different flow velocities. The results showed that the effectiveness of binder-assisted seeding of kelp propagules was not affected by flow velocities and was comparable to the non-binder treatment.

Summary: Seaweeds have a long history of varied use in food, feed, and medicine. Despite the dominance of a few species in the seaweed industry, interest is growing in specific varieties like Macrocystis pyrifera and Laminaria digitata due to their polysaccharide and protein properties, with potential applications in functional foods and other areas.

Summary: Industrialized aquaculture is an essential trend in China due to its advantages in lower water consumption, higher productivity, and sustainability. However, the current status and problems of industrialized aquaculture in China have been poorly documented. This paper reviews the current status, identifies existing problems, and proposes possible solutions for the development of industrialized aquaculture. Major constraints include high costs, uncompetitive market prices, uneven distribution, lack of experienced managers and operators, and the impact of the COVID-19 pandemic. Possible solutions include technological innovations, renewable energy sources, pollution-free certification, increased professionals in water control and waste management, and financial assistance.

Summary: The production of high-quality seedlings is crucial for horticultural productivity. This study investigated the use of Euterpe oleracea residue as a substrate for Coriandrum sativum seedling production in an aquaponic system. The results showed that using more than 25% of Euterpe oleracea offal had a negative impact on plant growth.

Summary: The study investigated the growth rates of male and female multiannual delayed gametophyte strains of Saccharina latissima and Alaria esculenta in culture, as well as how changing sex ratios affect reproductive yields of these cultures. Results showed that reproductive yields declined with decreasing male:female ratios, especially at higher culture densities. Female gametophyte densities had a significant impact on reproductive yield, with higher amounts of female gametophyte biomass halting gametophyte reproduction.

Summary: This paper systematically reviews the life-cycle, diversity, seedling culture, and cultivation of Scytosiphon lomentaria, based on previous experiences and published papers. Perspectives and methods of industrial development pertaining to this species are also briefly discussed. A new efficient cultivation method, filaments-derived seedling, is proposed, which includes establishing uncontaminated germplasm, amplificatory of filaments, reproductive induction of free-living filaments, in-door tank culture of seedlings, and in-situ cultivation. This method is considered to be a potential strategy for the future large-scale cultivation of S. lomentaria, due to its simplicity, high stability, and low-energy consumption.

Summary: Aquaculture ponds in China contribute significantly to methane emissions at the national level, with larger emissions compared to reservoirs and lakes. However, the emission intensity of aquaculture species is lower than other major livestock sources. Further field measurements are needed to reduce uncertainty in methane emissions from aquaculture ponds.

Summary: Aquaculture ponds are exposed to potential microplastic sources, with differences in microplastic pollution characteristics depending on the type of aquaculture species. This study found that crab ponds had higher microplastic abundances compared to fish ponds and nearby lakes, with varying sizes and shapes of microplastics observed. The results suggest that the use of plastics in different types of aquaculture ponds can impact microplastic pollution, and further attention is needed to address the drainage of microplastics from ponds to nearby lakes.

Summary: This study investigated the occurrence and distribution of seven antibiotics in aquaculture areas in Guilin, South of China, revealing relatively low concentrations of antibiotics but potential risks to microorganisms and organic matter in water and sediment. The results suggest that antibiotics may not pose a direct risk to human health via dietary exposure, but could lead to secondary pollution in sediments, thus requiring heightened local management awareness.

Summary: The environmental impact of tiger puffer farming in China was evaluated using a life cycle assessment (LCA), with a focus on energy consumption and carbon emissions. The study identified the marine aquatic ecotoxicity potential as the largest contributor to the environmental impact. Industrial recirculating aquaculture was found to be the most significant farming stage. Recommendations were made to improve the environmental performance, including the use of renewable energy sources and the exploration of new production strategies.

Summary: Through analyzing the spatiotemporal variation patterns of shrimp aquaculture in China over the past 18 years, it was found that shrimp aquaculture production has been steadily increasing with an average annual growth rate of 5.2%, the spatial distribution of shrimp farms has expanded in a zonal pattern from northeast to southwest, and factors such as the level of development in the fishing industry, labor quantity, and per capita income are the main influences on the spatial distribution variability of shrimp aquaculture, with the degree of influence varying temporally.
