Growth and loss of mariculture kelp Saccharina japonica in Sungo Bay, China. However, a focused monitoring program assessing phytoplankton changes and resulting effects would be required to determine the potential negative interactions at larger scales. To summarize some of the potential changes associated with this type of habitat creation this review focuses on three major species groups (plankton, benthic species and epifauna and megafauna species). A., Withyachumnarnkul, B., Itsathitphaisarn, O., et al. This suggests that a proportion of kelp exudates may be resistant to biological breakdown, and rDOC will join the oceanic carbon pool which is estimated to be 4,0006,000 years old (Bauer and Druffel, 1998).

Commercial cultivation and bioremediation potential of sugar kelp, Saccharina latissima, in Danish waters. Spain. The diving behavior of marine mammals puts them at risk of interaction with infrastructure, as it may not be possible to avoid infrastructure when resurfacing for air. This avoids collecting monitoring data to assess the significance of changes against a null hypothesis of no-change. Organic enrichment of submarine-canyon and continental-shelf benthic communities by macroalgal drift imported from nearshore kelp forests. Cultivated seaweed habitats differ from natural macroalgal habitats as the crops must be cultivated in surface waters at depths that optimizes levels of Photosynthetically Active Radiation (PAR).

Not all salmon are created equal: life cycle assessment (LCA) of global salmon farming systems. In most jurisdictions, marine mammals are protected and there is a statutory responsibility to consider interactions when planning marine developments. Sublittoral kelps are recognized as important habitats for a range of invertebrate macrofauna (Christie et al., 2009; Norderhaug and Christie, 2011), which in turn supports a diverse ichthyofaunal assemblage (Norderhaug et al., 2005). As a result, preventing the introduction of new NNS and restricting the likelihood of secondary introductions is typical of current marine management policies in Europe [e.g., Regulation (EU) No 1143/2014 of the European Parliament and of the Council of 22 October 2014 on the prevention and management of the introduction and spread of invasive alien species]. Foliar fertilizersseaweed-based biogenic ZnO nanoparticles: Seaweeds washed with tap water, shade dried, . As the overall consequence of large-scale cultivation is currently unknown cultivation activities must be managed responsibly to ensure that infrastructure deployed is well maintained and fit for purpose to avoid accidental loss of infrastructure at sea, as is required of other aquaculture activities across Europe through multiple regulations (EC, 2016).

Despite the possibility of shading effects on sessile organisms located under cultivation projects, water movement required for efficient nutrient and gas exchange among cultivated species mean that phytoplankton communities will only experience shading for the length of time it takes to travel through the site. High demand has driven a rapid expansion in Asia in this form of aquaculture. The authors would like to acknowledge the Macrofuels project. Cultivation of seaweeds on surface waters may therefore shade underlying habitats containing autotrophic organisms (e.g., pelagic phytoplankton and benthic macroalgae). Total Environ. These include: siting that minimizes damage to sensitive environments; seed sources that maintain the genetic diversity of wild stocks; no cultivation of non-native species; biosecurity measures to control the spread of diseases, parasites and non-natives; no fertilization; and infrastructure which is well maintained (e.g., The Water Framework Directive- Council Directive 2000/60/EC, and Council Regulation EC No. Springer, Cham.

It is likely that negative and/or positive environmental changes may be correlated with one or more of the variables expressed in equation 1. Benthic shading by kelp can affect understory algae, as kelp canopies are capable of reducing light that reaches the benthos by <3% of surface influx (Reed and Foster, 1984). Together these species account for 66% of the global production (FAO, 2015). The development of large-scale seaweed aquaculture in Europe has the potential to play an important role in meeting future resource needs, but must do so in a manner that does not undermine the use and value of existing marine resources.
