Aquaculture expansion is limited by the negative environmental impact of the waste and the need for alternative sources in the diet of reared fish. In this framework, for the first time, the survival rates, biomass gain, and fatty acid profiles of the polychaete Sabella spallanzanii and the macroalga Chaetomorpha linum, reared/cultivated as bioremediators in an integrated multitrophic aquaculture system (IMTA), were evaluated for their potential reuse applications. Results showed that these organisms represent a natural source of omega-3 and omega-6. On account of the overall results and the high biomass obtained as by-products, a preliminary study was performed employing both S. spallanzanii and C. linum as new dietary ingredients to feed different sized Dicentrarchus labrax. Fish survival rate, biomass growth, and specific growth rate were determined resulting in no significant differences between control and treated fishes. Histological analyses showed no alterations of the stomach tunica mucosa and submucosa in treated fishes. The eco-friendly approaches applied in the here-realized IMTA system could guarantee the achievement of sustainable by-products represented by the bioremediators S. spallanzanii and C. linum, as well as their reliability as a natural source of compounds beneficial to fish and human health.

“…During the cultivation, activities carried out seaweed control/maintenance every 2 days by cleaning the moss and dirt inherent as well as disruption of pests. The growth rate was determined using the following formula (Mtolera et al, 1995;Gerung and Ohno 1997;Aguirre-von-Wobeser et al, 2001;Bulboa et al, 2007;Hayashi et al, 2007aHayashi et al, , b, 2011Hung et al, 2009;Yong et al, 2013) …”

“…The growth of H. musciformis and K. alvarezii in vitro and in the sea were expressed by Daily Growth Rate (DGR) and Carrageenan Yield (CY). The DGR was calculated according to the formula:

DGR = [{(final dry mass / initial dry mass)}^{1 / normaltime normalcultivation} - 1] \times 100

(Yong, Yong & Anton ). The semi‐refined carrageenan yield was estimated by the formula:

CY (%) = (dry mass of carrageenan / dry mass of seaweed) \times 100

Hypnea musciformis: alternative or complement to the production ofKappaphycus alvareziiintroduced in tropical countries?

Hypnea musciformis that are harvested from natural beds and introduced Kappaphycus alvarezii are the two main sources of raw material for the production of carrageenan in Brazil. The daily growth rate (DGR) and carrageenan yield (CY) of both species were evaluated in vitro and in the sea to assess the feasibility of cultivating H. musciformis as a complement or as an alternative to the production of K. alvarezii. The DGR of H. musciformis (10.8 ± 0.6% day−1) was higher than the DGR of K. alvarezii (5.6 ± 0.3% day−1) in vitro, and the CY extracted using NaOH (62.3 ± 0.15%) was better than using KOH (32.0 ± 0.3%). In eutrophic medium, the DGR of H. musciformis (9.4 ± 2.1% day−1) was higher than that of K. alvarezii (5.0 ± 1.2% day−1). However, in this condition, the CY was similar for both species (50.2 ± 3.5%), and both species were effective in removing nutrients (30% NH4+, 18% NO2− and 2.4% PO43−). H. musciformis did not survive when cultivated in the sea, neither in monospecific nor in multispecific cultivation. Moreover, K. alvarezii grew better in monospecific cultivation throughout the year (from 1.73 to 5.15% day−1) except during the wet period and the CY was high in both cultivation types (33.7–50.8%). We conclude that the cultivation of H. musciformis is not an alternative to K. alvarezii on the Brazilian southeastern coast. However, the results in vitro suggested its use as a complementary source of carrageenan or as a biological filter.
