“…Various species of nutrient absorbers, suspension feeders, deposit feeders, and other organic-extractive organisms (Table 1) are candidate organisms that can be co-cultured with the targeted species (finfish, e.g., red sea bream F5, Atlantic salmon F7) in an IMTA system (Zhou et al, 2006;Aveytua-Alcazar et al, 2008;Abreu et al, 2009;Mao et al, 2009;Shi et al, 2011;Yokoyama, 2013;Brito et al, 2014;Yokoyama et al, 2015;Cubillo et al, 2016;Fang et al, 2016;Alexander & Hughes, 2017;Shpigel et al, 2017;Laramore et al, 2018;Zamora et al, 2018).

“…Thus, effective utilization of aquaculture wastes through the IMTA system can mitigate and alleviate the adverse impacts on the environment and aquatic animals. Practice of IMTA The rudiment of IMTA in fresh water has been found in China centuries ago, which was applied in marine aquaculture and arose the interest of many other countries in Asia (Bangladesh, Japan, Korea), North America (Canada, United States), Europe (France, United Kingdom, Spain), Oceania (Australia, New Zealand), and South America (Chile) in the last few decades (Yang et al, 2004;Zhou et al, 2006;Buschmann et al, 2008;Abreu et al, 2009;Ren et al, 2012;Yokoyama, 2013;Irisarri et al, 2015;Park et al, 2015;Fang et al, 2016;Shpigel et al, 2017). The selection of suitable candidate organisms varies with locations ( Table 2); for example, the blue mussel (e.g., D5) is Canada's top shellfish aquaculture product and was initially chosen as the organic-extractive species in the Bay of Fundy.…”

In general, aquaculture wastes from traditional aquatic organism cultivation rapidly deteriorate the water quality of the surrounding ecosystems, endangering animals living in the area. The integrated multitrophic aquaculture (IMTA) system is a bio-mitigation strategy to alleviate the adverse impacts caused by aquafarming pollutants on the environment and aquatic species. This study provides an overview of the IMTA system, explains the interactive processes among the different trophic levels, summarizes the major practices being followed around the temperate coastal waters with a field case study in Japan, and discusses the assessment of IMTA bio-mitigation efficiency through experimental greatly dependent on the customs and market values in the local IMTA practice. Bio-mitigation efficiency acquired in a land-based experiment exhibits its limitation in approach and conducts a comprehensive analysis on the possibility of applying numerical models to evaluate IMTA effectiveness. The selection of a suitable candidate organism is estimating that in the same or different culture conditions with various biomasses of extractive species. However, in open water experiments, it is difficult to evaluate the bio-mitigation effect of extractive species because the initial biomass ratio (IBR) of the extractive to target species is too small. Alternatively, the possibility of applying existing numerical models to assess IMTA is relatively low. In conclusion, an optimally designed large-scale IMTA experiment is required, in which the IBR of the extractive to target species is adequately considered, and a full-scale IMTA model should be further improved with a database of individual-based submodels for IMTA candidate organisms.

“…With its broad environmental plasticity, high growth rate, and multipurpose biomass usage, green macroalgae provide novel and reusable sources of compounds and materials of potential applicability in several sectors (Hafting et al, 2015). In particular, members of the widespread genus Ulva are already playing an essential role in the food (Colombo et al, 2006;Abreu et al, 2014;Santos et al, 2015), pharmaceutical, and cosmetic industries (Barzkar et al, 2019) as well as in fish aquaculture (Neori et al, 2004;Naidoo et al, 2006;Shpigel et al, 2017) to and for the generation of biofuels (Chen et al, 2015;Abomohra et al, 2018).…”

Cultivating the Macroalgal Holobiont: Effects of Integrated Multi-Trophic Aquaculture on the Microbiome of Ulva rigida (Chlorophyta)

et al. 2020

Ulva is a ubiquitous macroalgal genus of commercial interest. Integrated Multi-Trophic Aquaculture (IMTA) systems promise large-scale production of macroalgae due to their high productivity and environmental sustainability. Complex host-microbiome interactions play a decisive role in macroalgal development, especially in Ulva spp. due to algal growth-and morphogenesis-promoting factors released by associated bacteria. However, our current understanding of the microbial community assembly and structure in cultivated macroalgae is scant. We aimed to determine (i) to what extent IMTA settings influence the microbiome associated with U. rigida and its rearing water, (ii) to explore the dynamics of beneficial microbes to algal growth and development under IMTA settings, and (iii) to improve current knowledge of host-microbiome interactions. We examined the diversity and taxonomic composition of the prokaryotic communities associated with wild versus IMTA-grown Ulva rigida and surrounding seawater by using 16S rRNA gene amplicon sequencing. With 3141 Amplicon Sequence Variants (ASVs), the prokaryotic richness was, overall, higher in water than in association with U. rigida. Bacterial ASVs were more abundant in aquaculture water samples than water collected from the lagoon. The beta diversity analysis revealed distinct prokaryotic communities associated with Ulva collected in both aquacultures and coastal waters. Aquaculture samples (water and algae) shared 22% of ASVs, whereas natural, coastal lagoon samples only 9%. While cultivated Ulva selected 239 (8%) host-specific ASVs, wild specimens possessed more than twice host-specific ASVs (17%). Cultivated U. rigida specimens enriched the phyla Cyanobacteria, Planctomycetes, Verrucomicrobia, and Proteobacteria. Within the Gammaproteobacteria, while Glaciecola mostly dominated the microbiome in cultivated algae, the genus Granulosicoccus characterized both Ulva microbiomes. In both wild and IMTA settings, the phylum Bacteroidetes was more abundant in the bacterioplankton than in direct association with U. rigida. However, we observed that the Saprospiraceae family within this phylum was barely present in lagoon

“…Production of Ulva spp. has been successfully integrated with other types of aquaculture such as abalone (Bolton et al 2009) and fish (Sphigel et al 2017). Apart from its beneficial function as a nutrient scrubber, the produced biomass also has very interesting functional and nutritional properties and can be used directly as food (Bolton et al 2016), or turned into value-added products such as functional foods, cosmeceuticals, nutraceuticals, or pharmaceuticals (Hafting et al 2015).…”

Effects of irradiance, temperature, nutrients, and pCO2 on the growth and biochemical composition of cultivated Ulva fenestrata

Ulva fenestrata is an economically and ecologically important green algal species with a large potential in seaweed aquaculture due to its high productivity, wide environmental tolerance, as well as interesting functional and nutritional properties. Here, we performed a series of manipulative cultivation experiments in order to investigate the effects of irradiance (50, 100, and 160 μmol photons m−2 s−1), temperature (13 and 18 °C), nitrate (< 5, 150, and 500 μM), phosphate (< 1 and 50 μM), and pCO2 (200, 400, and 2500 ppm) on the relative growth rate and biochemical composition (fatty acid, protein, phenolic, ash, and biochar content) in indoor tank cultivation of Swedish U. fenestrata. High irradiance and low temperature were optimal for the growth of this northern hemisphere U. fenestrata strain, but addition of nutrients or changes in pCO2 levels were not necessary to increase growth. Low irradiance resulted in the highest fatty acid, protein, and phenolic content, while low temperature had a negative effect on the fatty acid content but a positive effect on the protein content. Addition of nutrients (especially nitrate) increased the fatty acid, protein, and phenolic content. High nitrate levels decreased the total ash content of the seaweeds. The char content of the seaweeds did not change in response to any of the manipulated factors, and the only significant effect of changes in pCO2 was a negative relationship with phenolic content. We conclude that the optimal cultivation conditions for Swedish U. fenestrata are dependent on the desired biomass traits (biomass yield or biochemical composition).
