Seaweed cultivation holds significant importance in addressing global challenges.On the one hand,it aids in alleviating the food crisis.On the other hand,it offers substantial ecological benefits,such as enhancing carbon sequestration,facilitating nitrogen cycling,and mitigating eutrophication(He et al.,2008;Wu et al.,2015;Mantri et al.,2023).Globally,the dominant cultivated economic seaweeds include Laminaria spp.,Kappaphycus spp.,Gracilaria spp.,Neopyropia spp.,and Undaria spp.(Park et al.,2021;Khan et al.,2024).In 2022,the annual global production of seaweed is estimated to be approximately 36.4 million metric tons(live weight),with red algae accounting for about 55.8% and brown algae for approximately 43.8%(FAO,2024).Asia constitutes the principal region for seaweed cultivation,representing over 97% of global production,with China(about 60%),Indonesia(about 25%),South Korea(about 5%),and the Philippines(about 4%)being the largest contributors to this industry(Khan et al.,2024;Liu et al.,2024).Among them,the Neopyropia species,a type of high-end red algae,is highly favored among consumers(Li et al.,2023)and possesses rich edible and medicinal values(Subramaniyan et al.,2021;Zhao et al.,2023).It is frequently utilized for the production of foods such as laver sushi and laver pancakes.Consequently,the significance of laver cultivation is self-evident.China boasts the world's largest laver cultivation area,with total production reaching 209,939 metric tons(dry weight)in 2023(...
