“…Previous studies have reported that jellyfish fertilizer increases soil moisture due to jellyfish's colloidal and hydrophobic nature (Chun et al, 2012). According to Emadodin et al (2019), jellyfish dry matter can absorb and hold water in the soil, and Kim et al (2012) reported that jellyfish fertilizer could hold water around the plants nearly seven times the fertilizer's weight. This study also reports the high water holding capacity of prepared jellyfish fertilizers and the potential of using jellyfish as a liquid fertilizer can also be explored in future studies.…”

Jellyfish are free-floating gelatinous animals belonging to the subphylum Medusozoa of the phylum Cnidaria. Nineteen jellyfish species have been reported in Sri Lanka and their abundance is found to be high (making 15,600 tons biomass per year). The seasonal occurrence of jellyfish blooms is widespread along the coast of Sri Lanka, interfering with human activities, including tourism and fisheries. This study aims to assess the possibility of using jellyfish blooms as a commercially available organic fertilizer. Highly abundant four jellyfish species, Lychnorhiza malayensis, Chrysaora sp., Chiropsoides buitendijki, and Marivagia stellata in the coastal waters of Sri Lanka were selected for this study. Using the traditional composting procedure, jellyfish fertilizers were prepared and the total nitrogen, phosphorus, potassium, water holding capacity, and pH of each fertilizer were assessed using standard procedures. The effectiveness of these fertilizers was tested by treating them separately on Okra (Abelmoschus esculentus) plants (n = 10 per treatment) once a week with a positive (commercial-grade compost) and negative control. Height, number of leaves, flowers, and fruits of each plant were recorded weekly for 10 weeks. All jellyfish fertilizers had higher phosphorus (10.01-22.09 g/kg), and lower potassium (0.66-1.88 g/kg) levels than the commercialgrade compost (~10 g/kg; ~5 g/kg, respectively), and their nitrogen levels ranged from 6.24 to 23.34 g/kg. The fertilizers prepared using L. malayensis (15.12 g/kg) and Chrysaora sp. (23.34 g/kg) showed significantly higher nitrogen content than that of commercial-grade compost (10 g/kg; p < 0.05; ANOVA). The average height and growth rate of plants treated with jellyfish fertilizers and commercial-grade compost were mostly within the same range during the experimental period of 10 weeks. Plants treated with jellyfish fertilizers showed flowering between 35 to 40 days, where compost-treated plants showed no evidence of flowering within the experimental period. Further studies are warranted on the potential use of jellyfish as a potential organic fertilizer that can be widely promoted locally.

“…In Russia, jellyfish have been successfully added to cement, which ultimately increased the mechanical strength of traditional cement by 50 % (CIESM 2010), although unfortunately the details are vague. Experiments have also demonstrated that jellyfish can successfully be used as fertilizer for a variety of plants, trees, and crops (e.g., Fukushi et al 2004Fukushi et al , 2005Chun et al 2011;Kim et al 2012;Hossain et al 2013;Hussein and Saleh 2014;Seo et al 2014;Hussein et al 2015). There are even recent reports that a company in Israel has developed an absorbent and biodegradable material from jellyfish that could be used in products such as diapers and paper towels (Shamah 2014).…”

Jellyfish (primarily scyphomedusae) fisheries have a long history in Asia, where jellyfish have been caught and processed as food for centuries. More recently, jellyfish fisheries have expanded to the Western Hemisphere, often driven by demand from Asian buyers and collapses of more traditional local fish stocks. Jellyfish fisheries have been attempted in numerous countries in North, Central, and South America, with varying degrees of success. Here, we chronicle the arrival of jellyfish fisheries in the Americas and summarize relevant information on jellyfish fishing, processing, and management. Processing technology for edible jellyfish has not advanced, and presents major concerns for environmental and human health. The development of alternative processing technologies would help to eliminate these concerns and may open up new opportunities for markets and species. We also examine the biodiversity of jellyfish species that are targeted for fisheries in the Americas. Establishment of new jellyfish fisheries appears possible, but requires a specific combination of factors including high 123Rev Fish Biol Fisheries DOI 10.1007/s11160-016-9445-y abundances of particular species, processing knowledge dictated by the target market, and either inexpensive labor or industrialized processing facilities. More often than not, these factors are not altogether evaluated prior to attempting a new jellyfish fishery. As such, jellyfish fisheries are currently expanding much more rapidly than research on the subject, thereby putting ecosystems and stakeholders' livelihoods at risk.

“…By‐catch jellyfish are often landed and disposed of. Alternatively, jellyfish are sometimes used as an agricultural fertilizer (Kim, Kim, Damdinsuren, Ezaki, & Chun, ) or for the extraction of valuable chemicals, for example collagen (Barzideh, Latiff, Gan, Benjakul, & Karim, ), although few methods are commercially viable owing to the high costs of desalination and transportation.…”

Efficacy of feeding tiger pufferTakifugu rubripeson moon jellyfish with respect to nutritional composition and behavioural traits

et al. 2017

Although jellyfish blooms are serious nuisances for fisheries and other industries, the utilization and nutritional value of by‐catch jellyfish has drawn public attention. Here, we evaluated the efficacy of feeding tiger puffer Takifugu rubripes with moon jellyfish Aurelia sp. using 20‐day rearing experiments. Feeding on jellyfish had no positive effect on growth performance, although it significantly reduced neutral lipids and increased proportions of polar lipids, n−3 and n−6 highly unsaturated fatty acids (HUFAs), especially arachidonic and docosahexaenoic acids, and taurine. Supplemental feeding on jellyfish plus pellets elevated activity and responsiveness in the fish, with no effect on burst swimming speed or prevention of aggressive biting by siblings. The present research suggests that feeding on jellyfish improves body composition and some behaviours in tiger puffers. As cultured fish tend to accumulate excessive amounts of lipids from lipid‐rich pellets that can induce an unhealthy condition, and behavioural deficits of hatchery‐reared fish reduce survival after release in the wild, we propose the use of jellyfish as a supplemental diet in the nursery production of tiger puffer. Moreover, feeding on jellyfish can overcome deficiencies in alternative soy‐material feeds by supplying phospholipid, HUFAs, or taurine.
