Summary: The study reports the nutritional value and heavy metal profiling of two Australian kelps cultivated through integrated multitrophic aquaculture systems in southeastern Australia. The results suggest that these kelps have suitable nutritional composition for human and animal consumption, but the iodine content exceeds the maximum tolerable level established by food standards.

Summary: The study revealed that sea urchins fed with polluted kelps from highly impacted zones showed lower growth rates and gamete release compared to those fed with non-impacted kelps. Additionally, the polluted kelps caused developmental delays and an increase in malformed larvae, indicating that pollutants ingested by sea urchins can be transferred to their offspring, negatively impacting their early development and categorizing Macrocystis pyrifera as a pollutant carrier.

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: This study introduces a new method for kelp production by adjusting the temperature to slow down gametophyte growth and reproduction, allowing for extended storage time. Storing seeded twine in cold banking conditions can prolong storage time without negative effects on kelp growth, improving aquaculture efficiency.

Summary: The study found that in mid-latitudes, floating kelps are quickly replenished from benthic sources during summer, while the biomass of floating kelps remains high in fall. Wind speed is a good predictor for the biomass accumulations of the two kelp species.

Summary: The sub-Antarctic Magellan Ecoregion at the southern tip of South America is characterized by exceptional marine flora and high endemism. Algal species Macrocystis pyrifera and Lessonia flavicans play crucial roles in providing important habitats for marine organisms, as well as being significant components in the food industry and biomedicine due to their nutrient content. This study revealed intra-thallus variation of fatty acids in different morphological structures of M. pyrifera and L. flavicans, highlighting their potential nutritional and biomedical importance.

Summary: The newly created Kawesqar National Park and National Reserve in southern Chile encompass diverse terrestrial and marine habitats, including the southern terminus of the Andes and sub-Antarctic rainforests. The marine environment is influenced by various hydrological factors, and an integrated ecological assessment using SCUBA and remote cameras was conducted to examine the largely unexplored ecosystem. The study revealed kelp forests dominating the nearshore ecosystem and benthic communities varying in composition based on proximity to the Pacific Ocean.

Summary: This research aimed to extract sodium alginate from brown algae Macrocystis pyrifera and Lessonia trabeculata, and produce composite films composed of sodium alginate/ kappa-carrageenan/ iota-carrageenan, which were loaded with aminoethoxyvinylglycine. The extracted sodium alginate had low molecular weight and the composite films showed desirable drug release properties. Therefore, sodium alginate can be used to prepare composite films as an alternative to synthetic polymers for drug loading and release.

Summary: The ocean has the potential to function as a carbon sink, and shellfish culture can be used to increase its carbon sink capacity. We analyzed the production and carbon sink capacity of six important mariculture shellfish species in nine coastal provinces of China and found that both production and contribution to the carbon sink generally increase.

Summary: In this study, the productivity of an outdoor cultivation system using secondary attachment discs (SADs) of Chondracanthus chamissoi was evaluated. It was found that utilizing fiberglass as the substrate was the most suitable choice, as it increased the survival rate of SADs and improved the growth of seaweeds within the tanks.

Summary: The study of pollution effects in the marine environment has become increasingly important in recent decades, with a focus on the impact of exposure to multiple pollutants. Research shows that Macrocystis pyrifera exposed to a mixture of heavy metals and polycyclic aromatic hydrocarbons experienced negative effects on growth and morphology. Additionally, the associated community structure, including M. pyrifera grazers, also suffered from low richness and diversity due to the pollution pulse.

Summary: Several seaweed species are widely commercialized globally due to their demand in food, feed, and the extraction of phycocolloids. Chile is the leading producer, but overexploitation has caused a decrease in natural stocks. Various strategies have been implemented to restore seaweed stocks, with varying success rates. However, technological improvements are needed to develop cost-effective restocking strategies that are scalable, transferable, and socio-ecologically sustainable.
