“…Although farmers cut out the infected parts of the seaweeds during the vegetative selection of cultivars, proper disposal was never practiced. In Malaysia, the use of healthy and uninfected propagules, regular simple cleaning of seaweed thallus and farm ropes to remove biofouling and early identification of infected stocks were proven to be effective simple biosecurity measures (Cottier-Cook et al 2022). Hurtado et al (2021) and Mateo et al (2021) further corroborated the lack of biosecurity measures in the country's seaweed industry.…”

“…The only existing policies in seaweed aquaculture are the Good Aquaculture Practices for seaweeds (GAqP, PNS/BAFS 208:2021 and Dried Raw Seaweeds (RDS, PNS/BAFS85:2021). However, enhancing biosecurity measures will require strict monitoring and implementation of guidelines and the participation of all players in seaweed farming (Hurtado et al 2021;Mateo et al 2021;Cottier-Cook et al 2022). Moreover, simple management strategies such as the implementation of regular cleaning of long lines and manual removal of epiphytes as quickly as possible (Ask and Azanza 2002) and proper disposal can decrease its impact on seaweeds (Ward et al 2019).…”

Many coastal dwellers engage in seaweed farming despite of various challenges because of its simple farming technology, low capital investment, and short cultivation period. This paper explored the attitudes of seaweed farmers (n = 187) from nine coastal communities of Aborlan, Puerto Princesa, Roxas, and Taytay, Palawan towards the difficulties and challenges they experienced. The farmers’ experiences in seaweed farming, mid-term aspirations, and factors affecting their positive attitudes towards seaweed farming were gathered using a Likert-scale questionnaire in KoBoToolbox. Focused group discussion (FGD) sessions were also conducted to obtain more data about their optimistic attitudes. Participants are 55% male and 45% female. Results revealed that farmers had a high level of optimism toward seaweed farming. The majority (75%) ‘will continue to engage in planning the next cropping cycle’, most (89%) ‘are expecting to have a good harvest’, and almost all (96%) ‘are planning to generate raw dried seaweeds from their harvest.’ Many (59%) of the respondents obtained high earnings from seaweed farming, but most (93%) experienced economic losses. As recovery options, 92% aspired to culture other organisms such as sea cucumber and abalone. Further, most of them wanted to seek assistance from government offices (91%), participate in seaweed product development (86.5%), and join a cooperative (87.5%). This study could serve as baseline information in designing relevant training and educational activities to assist seaweed farmers in managing their farms sustainably. Subsequently, this could aid in formulating effective policies to address similar problems of seaweed farmers in other municipalities of Palawan.

“…Nevertheless, as the peak biomass period in a seaweed farming season is short and typically happens towards the end of the season, the ecological impact on photosynthetic benthic communities is likely minimal. However, it is wise to steer clear of densely vegetated areas or protected habitats to mitigate potential compounding effect on primary production, especially as the scale and density of seaweed farms increase [55].…”

We explore the biodiversity impacts of seaweed and shellfish farms in Pembrokeshire, UK, with a focus on using monitoring methods that are affordable and can be integrated into existing seaweed farming operations. Monitoring methods used include Baited Remote Underwater Video Systems (BRUVs), Passive Acoustic Monitoring (PAM) and visual surveys of cultivation lines and natural settlement on farm infrastructure. BRUVs detected 13 motile fauna taxa, influenced mainly by site conditions, while PAM observed distinct patterns in dolphin and porpoise activity that changes between seasons. Visual surveys revealed colonisation of algal, hydroid, and bryozoan species on both the surface and seabed infrastructure, indicating that the farming structures serve as stable substrates for biodiversity accumulation. Apart from the natural settlement on infrastructure, our data does not show a conclusive link between biodiversity and farming due to the highly dynamic environment, small scale of operations, and relatively short monitoring timeframe. Despite these limitations, the data sets a crucial baseline for future studies and showed no negative impacts even as farming activities intensified over the monitoring period. The study aligns with what's feasible for time-constrained farm operators and forms a foundation for routine, integrated environmental and biodiversity monitoring.

“…Nowadays, seaweeds contribute to half of all mariculture worldwide and are now a major participant in bio-based businesses [19,20]. Hot water blanching, which is often the first step in the seaweed processing, reduces postharvest quality decline but also produces a significant amount of hydrothermal waste.…”

Potential application of Saccharina japonica and its extracts in cosmetology

Saccharina japonica (S. japonica), a type of brown algae widely consumed in east Asia due to its enormous health benefits, has now been greeted with great expectation in the field of cosmetics. Although many cosmetological functions of S. japonica extracts have been reported, there is still a lack of comprehensive review on the potential application of S. japonica and its extract in cosmetology. This article aims to sum up the cosmetological functions of S. japonica extracts, including anti-inflammation, skin whitening, anti-oxidation, and anti-bacterial activities. Moreover, the production of bioactive chemicals from S. japonica is explored, hoping to provide new insights into cosmetic manufacturing. Study exploration was conducted using online databases (PubMed) using the keywords Saccharina japonica, Laminaria japonica, kelp, cosmetics, anti-inflammation, skin whitening, anti-oxidation, anti-bacterial, etc., focusing on established pre-clinical trials proving relative bioactivities.
