“…In the late 1960s, two protozoans, both in the genus Marteilia , Marteilia refringens and Marteilia sydneyi , were identified as the causative agents of disease and heavy mortalities in the flat oyster: O. edulis , in France, and in Saccostrea glomerata , in Australia, respectively [59]; afterward, the parasite become widespread: M. refringens , infecting O. edulis , has, to date, mainly been found in Europe (Albania, Croatia, France, Greece, Italy, Morocco, Portugal, Spain, Sweden, Tunisia and the United Kingdom); Mytilus galloprovincialis , in the Gulf of Thermaikos, northern Greece [60], on the north coast of the Adriatic Sea [61] and along the Campanian coast (Tyrrhenian Sea, South of Italy) [62]. Marteilia was also previously found in M. galloprovincialis bred in Puglia [63].…”

A variety of bivalve mollusks (phylum Mollusca, class Bivalvia) constitute a prominent commodity in fisheries and aquacultures, but are also crucial in order to preserve our ecosystem’s complexity and function. Bivalve mollusks, such as clams, mussels, oysters and scallops, are relevant bred species, and their global farming maintains a high incremental annual growth rate, representing a considerable proportion of the overall fishery activities. Bivalve mollusks are filter feeders; therefore by filtering a great quantity of water, they may bioaccumulate in their tissues a high number of microorganisms that can be considered infectious for humans and higher vertebrates. Moreover, since some pathogens are also able to infect bivalve mollusks, they are a threat for the entire mollusk farming industry. In consideration of the leading role in aquaculture and the growing financial importance of bivalve farming, much interest has been recently devoted to investigate the pathogenesis of infectious diseases of these mollusks in order to be prepared for public health emergencies and to avoid dreadful income losses. Several bacterial and viral pathogens will be described herein. Despite the minor complexity of the organization of the immune system of bivalves, compared to mammalian immune systems, a precise description of the different mechanisms that induce its activation and functioning is still missing. In the present review, a substantial consideration will be devoted in outlining the immune responses of bivalves and their repertoire of immune cells. Finally, we will focus on the description of antimicrobial peptides that have been identified and characterized in bivalve mollusks. Their structural and antimicrobial features are also of great interest for the biotechnology sector as antimicrobial templates to combat the increasing antibiotic-resistance of different pathogenic bacteria that plague the human population all over the world.

“…The main objective of treating aquaculture solid waste using BFT is to re-utilize nutrients, especially nitrogen in particles (Crab et al, 2007;Schneider et al, 2006). Bio-flocs produced was the vector for recycling nutrients.…”

“…A potential alternative, referred to as bio-flocs technology (BFT), uses the production of heterotrophic bacteria to convert the nutrients in aquacultural sludge into bacterial biomass (De Schryver and Verstraete, 2009;Schneider et al, 2006). The biomass could potentially be used as fish feed, thereby reducing waste discharge and increasing nutrient, particularly nitrogen, utilization efficiency (Kuhn et al, 2010).…”

“…Therefore, ex situ BFT system explored sequence batch reactors (SBR-BFT), in which culture units are portioned with bio-flocs have been advocated (Azim and Little, 2008;De Schryver and Verstraete, 2009). SBR-BFT was proved to be effective in producing heterotrophic biomass (Schneider et al, 2006) and treating aquaculture waste water (De Schryver and Verstraete, 2009). However, using SBR-BFT to treat aquaculture sludge and the nitrogen recycling process is not well studied.…”

“…The positive effects of BFT have been studied extensively (Crab et al 2012). In addition, it has been demonstrated that BFT reactors can be used in RASs as a sequencing bypass treatment unit to treat effluents from solid-liquid separation and to control the total ammonia nitrogen (TAN) concentration; moreover, they can reduce the amount of traditional biofilters needed and achieve RASs that yield zero discharge (Kuhn et al 2009;Schneider et al 2006;Avnimelech 1999).…”

Geosmin and 2-methylisoborneol (MIB) are two of the most common odorous compounds that critically affect the quality of fish. In the current study, the solid fish waste from a recirculating aquaculture system (RAS) was used as the substrate to produce bioflocs in suspended growth reactors (SGRs). The removal efficiency of geosmin and MIB by the bioflocs was investigated under in situ and in vitro conditions. The highest removal rates for geosmin and MIB in the SGRs were 187.00 ± 0.23 and 170.91 ng L -1 d -1 , respectively. Under the in vitro experimental conditions, 90.30 % of the geosmin and 72.93 % of the MIB were removed from the aqueous phase by the bioflocs within 48 h of incubation. It was found that the decay of these odorous compounds by the bioflocs was mediated by both chemical/physical sorption and biological degradation. Moreover, the addition of these odorous compounds did not affect the treatment efficiency of the reactors and had no adverse influence on the crude protein content of the bioflocs. Thus, using biofloc technology (BFT), SGRs can be used to reuse the nitrogen in fish waste and to remove geosmin and MIB from the culture water efficiently.
