“…The over exploitation of natural Gelidiella populations necessitated the development of cultivation methods for farming seaweeds. Initial methods included long-line ropes (Subbaramaiah et al 1975), single rope floating technique (SRFT; Subbaramaiah and Banumathi 1992), coral stone culture method (Patel et al 1986), and concrete stone method (Ganesan et al 2009). These methods resulted in low biomass yields and were difficult to manage in terms of planting, monitoring and harvest practices.…”

“…Therefore, it became necessary to develop improved methods resulting in higher biomass and easier cultivation operations. The bamboo raft method successfully used for the commercial cultivation of Kappaphycus alvarezii was adopted for G. acerosa (Figure 11A; Ganesan et al 2009) yielding significantly higher harvested biomass than previous methods. The suspended stone method was developed to enhance the bamboo raft method by tying approximately 2 g of seedlings to nylon thread, which was wound around the stones (15-70 cm 2 area and 100-200 g weight) and hung 5 cm below the polypropylene ropes (3 mm diam).…”

Seaweeds are an integral part of coastal ecosystems and offer invaluable ecosystem services supporting the life of many marine forms. The economic value of seaweeds significantly contributes to the sustainable development of rural coastal regions. Seaweeds are consumed as food in some Asian countries, but their utilization for production of phycocolloids is widespread across the globe, with an estimated value of more than one billion US$. In India, seaweeds have been utilized exclusively for the production of phycocolloids but recently they are used for the production of plant growth stimulants for agricultural applications. The domestic agar and alginate industry totally depends on the supplies from natural seaweed beds with some occasional imports. The recent success achieved in both upstream and downstream technologies in production and processing of seaweeds has boosted the prospects for commercialization of seaweed resources in the country. The present article briefly appraises the current status of Indian seaweed resources and their utilization, as well as developments in seaweed farming technologies, the status of seaweed industry and recent efforts to transform seaweed farming into a social enterprise. It also highlights the challenges encountered for mainstreaming these resources so as to evolve into a marine industry.

“…15,16 In the Indian context, the first incidence of epiphyte infestation was reported in Gracilaria edulis farming. 17 Thereafter, studies were conducted in different species such as Hypnea musciformis, Gelidiella acerosa, Gracilaria edulis, [18][19][20][21] Gracilaria dura, Gelidium sp. and Gracilaria deblis.…”

Seaweeds are macroscopic forms of phylogenetically diverse assemblage of marine algae that grow in oceans, thriving among profoundly harsh environmental conditions. They are cultivated in many maritime nations primarily for edible applications; besides hydrocolloid extraction is the second largest domain of utility for this renewable biomass. The farming practices have been traditionally evolved in different Southeast Asian countries. Nevertheless, advancement in the knowledge about their life‐history traits and control over reproduction has paved ways for commencement of large‐scale commercial farming. Food and Agriculture Organisation of United Nations reported the availability of 35.8 million tons of seaweed biomass globally of which 97% accounted for farming. Although cultivation is on the rise due to relevant to social gains, epiphytic infestation, diseases and grazing have been identified as leading causes that result in substantially lower yield, deteriorated quality of product and skewed economics. Epiphytes may considerably impact the interaction of seaweed hosts with other beneficial communities also. Epidemiological studies in natural seaweed populations are scarce and this makes the understanding of the cross‐talk involving host specificity, and their role obscure. An overview of the diversity of epiphytes, understanding of mechanism of action, factors responsible, chemistry behind their interaction will help in deciphering the solutions to overcome infestation. A comprehensive report of seaweed epiphytism, diseases and grazing from the aspects of host–epiphyte interaction and their resultant consequences is presented along with the studies on economic impacts. The role of multi‐omics approaches in delineating seaweed epiphytic interactions is also included.
