“…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). Wastes released from the fish farm can be used as food sources for inorganic and organic nutrient-extractive species.…”

“…Several studies on the possible applications of IMTA for land-based, inshore, and offshore systems with special interest in seaweed and shellfish have been examined (Buschmann et al, 2008;Fang et al, 2016;Perdikaris et al, 2016;Neori et al, 2017). The recent research includes a concern on assessing the bio-mitigation efficiency of IMTA based on experiments Irisarri et al, 2015;Martínez-Espiñeira et al, 2015;Milhazes-Cunha & Otero, 2017;Laramore et al, 2018). Nevertheless, due to the complex interactive processes involved in the IMTA, it is questionable whether a relatively accurate assessment of IMTA bio-mitigation effectiveness can be fully achieved through partially balanced experiments (Troell et al, 2009).…”

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.

“…Agricultural utilization of Ulva extracts was reported to enhance the vegetative growth in bean plants under drought stress, limiting the lipid peroxidation, increasing the phenolic content and probably contributing to the enhancement of the antioxidant enzymatic activity [37]. Ulva aqueous extracts enhance the vegetative growth under drought stress conditions and antioxidant potential for Salvia officinalis [38].…”

“…Water extraction of sulphated ulvan gives a product with a high antimicrobial activity against Enterobacter cloace and Escherichia coli [63]. A simple acidic method for extraction of Ulvan, with relatively low content of protein and high sulphate, is frequently used [30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64]. The properties and bioactivities of polysaccharides can be modulated by the extraction conditions; where rhamnose, glucuronic acid and glucose are the major monosaccharides obtained at 90 °C with 0.01 M HCl.…”

Ulva lactuca, A Source of Troubles and Potential Riches

2019

Ulva lactuca is a green macro alga involved in devastating green tides observed worldwide. These green tides or blooms are a consequence of human activities. Ulva blooms occur mainly in shallow waters and the decomposition of this alga can produce dangerous vapors. Ulva lactuca is a species usually resembling lettuce, but genetic analyses demonstrated that other green algae with tubular phenotypes were U. lactuca clades although previously described as different species or even genera. The capacity for U. lactuca to adopt different phenotypes can be due to environment parameters, such as the degree of water salinity or symbiosis with bacteria. No efficient ways have been discovered to control these green tides, but the Mediterranean seas appear to be protected from blooms, which disappear rapidly in springtime. Ulva contains commercially valuable components, such as bioactive compounds, food or biofuel. The biomass due to this alga collected on beaches every year is beginning to be valorized to produce valuable compounds. This review describes different processes and strategies developed to extract these different valuable components.

“…The use of macroalgae could significantly reduce the harvesting and dewatering costs compared with microalgae due to their larger size and tendency to grow as dense floating mats or substrate-attached turfs [17]. Macroalgae are usually used in integrated multitrophic aquaculture (IMTA) systems to maintain water quality and to serve as food for cultured species [18]. Bambaranda et al [19] tried to use Caulerpa lentillifera as a bioremediatory species instead of MBBR for nutrient removal in a RAS where a huge volume of macroalgae was needed to achieve the required high efficacy.…”

Rather than direct nutrient removal from wastewaters, an alternative approach aimed at nutrient recovery from aquacultural wastewaters could enable sustainable management for aquaculture production. This study demonstrated the feasibility of cultivating marine macroalgae (Chaetomorpha maxima) with a moving bed bioreactor (MBBR-MA), to remove nitrogen and phosphorus in aquaculture wastewater as well as to produce macroalgae biomass. MBBR-MA significantly increased the simultaneous removal of nitrate and phosphate in comparison with only MBBR, resulting in an average total nitrogen (TN) and total phosphorus (TP) removal efficiency of 42.8±5.5% and 83.7±7.7%, respectively, in MBBR-MA while MBBR had no capacity for TN and TP removal. No chemical oxygen demand (COD) removal was detected in both reactors. Phosphorus could be a limiting factor for nitrogen uptake when N : P ratio increased. The recovered nitrogen and phosphorus resulted in a specific growth rate of 3.86%–10.35%/day for C. maxima with an uptake N : P ratio of 6. The presence of macroalgae changed the microbial community in both the biofilter and water by decreasing the relative abundance of Proteobacteria and Nitrospirae and increasing the abundance of Bacteroidetes. These findings indicate that the integration of the macroalgae C. maxima with MBBR could represent an effective wastewater treatment option, especially for marine recirculating aquaculture systems.
