For example, observed biomass of S. latissima cultivated at a site in Spain produced approximately 16 kg m-1 on growing lines in one season (Peteiro and Freire, 2013a). (2007). While learning how to compost is one way to improve your garden soil, using seaweed may well take your garden to a whole new level.

The alginic acid in seaweed forms a filmy layer on plant surfaces. For a decade, local lawmakers pointed to fertilizer as a key killer of the Indian River Lagoon. of seaweed make it as distinguished organic manure. The assessment of risk associated with projects is complex and uncertainty is increased by a current lack of information regarding the likelihood of entanglement of different megafauna species with seaweed cultivation systems.

Human induced changes to sources and sinks of nutrients can have negative impacts on coastal ecosystems altering local ecology and ecosystem services (Shumway, 1990; Anderson et al., 2002; Heisler et al., 2008). 267, 107119. In a global assessment of invasive macroalgae introductions, 121 of 223 introductions were derived from aquaculture either through macroalgae cultivation or indirectly through shellfish farming (Williams and Smith, 2007). In 1983 the brown kelp U. pinnatifida native to Asia was introduced to the French Atlantic coast for commercial cultivation (Kraan, 2017). Mar. (2015). In addition the presence of vectors (e.g., movement of biofouling associated with vessels and other structures) must be managed in such a way as to reduce the potential risk that cultivation activities will result in the spread on NNS. Int. (2001). However, continuing trends toward increased seaweed aquaculture could still provide a significant contribution to climate change mitigation and adaptation though providing additional benefits through carbon capture (estimate 1,500 tons CO2 km-2 year-1), animal feed supplements that reduce levels of methane production, substituting synthetic fertilizers and mitigating coastal erosion through absorbing wave energy (Duarte et al., 2017). Received: 12 April 2018; Accepted: 21 February 2019;Published: 22 March 2019. This means farmers can grow seaweed using a process known as vertical, or 3D, farmingand reap large harvests from a small area. Contact and Competition between cultivated algae and phytoplankton can be expected at time intervals in the production cycle where algae growth is rapid and natural renewal of nitrogen resources is affected by altered water exchange. cookies.

The alternate fraction of these carbohydrate rich exudates will be bioavailable to microplankton such as bacterioplankton and phytoplankton, and could be rapidly utilized (Azam et al., 1983). Potassium, nitrogen, phosphorus are basic elements to boost the yield which is easily provided by all fertilizers in different ways. 58, 325343. Production of kelp-a major aspect of Chinas exploitation of the sea. Chamberlain, J. Helgolander Meeresuntersuchungen 52, 259275. The authors acknowledge the assistance from Visva-Bharati Library Network, West Bengal, India. A new FAU study suggests so. J. However, it is important that there is more clarity regarding which target cultivation species are permitted throughout Europe to ensure comparable approaches across neighboring countries. Seaweed may also be grown for energy where the carbohydrate-rich biomass is fermented to produce alcohol (Wargacki et al., 2012), or subjected to methanogenic anaerobic digestion (Fasahati et al., 2017). 29, 436459. 3, a hybrid of Laminaria gametophyte clones with a more than intraspecific but less than interspecific relationship. Such information would support a more holistic approach to managing nutrient levels and allow for the scaling of cultivation projects to the characteristics of the specific water body. doi: 10.3354/meps09422. doi: 10.1016/j.jclepro.2016.07.195, Seghetta, M., Trring, D., Bruhn, A., and Thomsen, M.

Available at: https://www.gov.scot/publications/seaweed-cultivation-policy-statement-2017/, Marinho, G. S., Holdt, S. L., Birkeland, M. J., and Angelidaki, I. (2014). In recent years, seaweed fertilizers have gained popularity due to their numerous benefits for plants and the environment. Whether you use fresh seaweed or store-bought seaweed fertilizer, there's no doubt that this gift from the sea has huge benefits for your plants, which makes it well worth seeking out. Ecol. Bioacoustics 17, 273275. The application of seaweed extracts was found to affect the growth and yield of many crops positively. Biofuel. J Appl Phycol 2:269272, Crouch IJ, van Staden J (1991) Evidence for rooting factors in a seaweed concentrate prepared from Ecklonia maxima. doi: 10.1111/j.1749-7345.1990.tb00529.x, Sieburth, J. M. (1969). Seaweeds have been employed as a fertilizer since the eighteenth century, although exclusively in the coastal areas. Many of these nutrients have to be converted into inorganic forms by soil bacteria and fungi before plants can use them, so they typically are more slowly released, especially during cold weather when soil microbes are not as active. Kelp cultivation sites may have similar effects on microplankton assemblage and function, and will need to be determined not only in relation to the size of the cultivation site, but also through a cascade of indirect effects, which will require further investigation. Plus, seaweed improves soil by adding natural nutrients, increasing soil organic matter, improving soil structure and tilth, increasing soil water holding capacity, reducing soil crusting issues, and reducing wind and water erosion.

It has, however, been possible to identify several important environmental risks based on this systematic review. In some areas, the introduction of non-native species through abandoned cultivation efforts has had a serious effect on local ecosystems and the economy. (2017). Mar.

Feed Management. Despite these challenges the environmental consequences of large-scale seaweed cultivation in these regions has remained relatively benign when compared to other form of aquaculture and can even offset risks by providing positive ecosystem services (Kim et al., 2017).

Once lost from the farm, debris may contribute to existing environmental pollution issues such as increasing levels of plastics in marine food webs (Derraik, 2002; Andrady, 2011) or social concerns such as the reduction in coastal amenities due to drifting debris (Sheavly and Register, 2007). Agreeing acceptable limits of change where possible will be necessary to design robust monitoring procedures, especially given a number of site specific positive and negative changes are likely to occur simultaneously in cultivation areas.
