“…These studies have also contributed to the evaluation of possible human health risks resulting from their consumption (Yüzereroğlu et al, 2010;Connan and Tack, 2010;Stankovic et al, 2012;Conti et al, 2012a;Jović and Stanković, 2014;Shefer et al 2015;Primost et al, 2017). For instance, a recent interesting study, connect the Cd contamination with the use of Mytilus chilensis valves as byproducts in agricultural applications (Blanc et al, 2018). Although the amounts of accumulated metals showed themselves as harmless for humans to ingest, they can be considered an index of human exposure as bivalves and patellid limpets are a common indigenous food in the studied areas (Conti, 2002;Kelepertzis, 2013;Yusà & Pardo, 2015;Pèrez et al, 2011Pèrez et al, , 2017.…”

In this study, we have investigated Cd, Cr, Cu, Ni, Pb and Zn in the biomonitors Mytilus chilensis and Nacella (P) magellanica sampled along seven selected sampling sites along km of the coastal area of the Beagle Channel (Tierra del Fuego, Argentina) in four sampling campaigns: 2005, 2007, 2011 and 2012. The control charts were built by applying Johnson's (Biometrika 36: 149-175, 1949) probabilistic method for the first time in this marine area. We determined the metal concentration overlap ranges in the selected biomonitors (as well as medians and distribution), and the overlap bioaccumulation index (OBI) with respect to the lowest (OBI-L1) and the highest (OBI-L) extreme values of the overlap metal concentration ranges. The OBI can be used as an integrative tool in the management of prevailing unpolluted/polluted marine coastal ecosystems. It consents to identify the most suitable organisms for managing several environmental conditions where an ecosystem quality control is needed. The OBI-L1 index can be employed as a preventive signal of alarm when the contamination process is in its early stages. For Cd, Cr, Cu, and Ni, Nacella showed high OBI-L values that suggest its use as a biomonitor for mainly polluted marine ecosystems, in particular for Cd. Mytilus showed high Cd values for the OBI-L1 which means that this species is highly sensitive to a very low variation of the Cd levels in seawater. Good OBI-L1 values were instead obtained for Mytilus for Cr and Cu, showing the good aptitude of these organisms to detect minimum variations of trace metals concentrations in seawater. The OBI index and its related guidelines have both theoretical and practical implications in environmental management. They can be used, for instance, in environmental prevention from events such as oil spills or other marine disasters. Marine ecosystems are complex systems. According to the Ashby's Law (1957, 1958), the understanding of a complex system (requisite variety) depends on the information variety owned by the observer. The OBI index enhances the observer's information variety about the performance of the molluscs as metal biomonitors in marine ecosystems. Eventually, here we propose to conceptualize the wide set of biomonitoring knowledge endowment as an open and evolutionary endowment of information variety supporting the environmental management.

“…In this context, besides the extraction of selected commercial phenotypes, the production cycle considers seed translocations from seedbeds, facilitating hybridization between individuals from relatively divergent locations, increasing the risk of a loss of locally adapted alleles and the erosion of genetic diversity [ 53 ]. However, translocated individuals also are exposed to a wide range of potentially pathogenic microorganisms [ 54 , 55 ], contamination [ 56 , 57 ], and environmental variability [ [58] , [59] , [60] ]. These factors can affect mussel health, shell biomineralization, reproductive performance, larval recruitment, and population growth [ [61] , [62] , [63] , [64] ].…”

“…However, the success of mussel aquaculture production in Chile is threatened by a wide range of microorganisms [ 3 , 4 , 5 ], marine pollution [ 6 ], and climate variability that can impact the larval settlement and growth of mussel populations [ 7 , 8 , 9 ]. To cope with those stressors, mussels and marine invertebrates produce two-component responses, a specific response to the stressor and a more general response involving immune and endocrine pathways [ 10 ].…”

The blue mussel Mytilus chilensis is an endemic and key socioeconomic species inhabiting the southern coast of Chile. This bivalve species supports a booming aquaculture industry, which entirely relies on artificially collected seeds from natural beds that are translocated to diverse physical–chemical ocean farming conditions. Furthermore, mussel production is threatened by a broad range of microorganisms, pollution, and environmental stressors that eventually impact its survival and growth. Herein, understanding the genomic basis of the local adaption is pivotal to developing sustainable shellfish aquaculture. We present a high-quality reference genome of M. chilensis, which is the first chromosome-level genome for a Mytilidae member in South America. The assembled genome size was 1.93 Gb, with a contig N50 of 134 Mb. Through Hi-C proximity ligation, 11,868 contigs were clustered, ordered, and assembled into 14 chromosomes in congruence with the karyological evidence. The M. chilensis genome comprises 34,530 genes and 4795 non-coding RNAs. A total of 57% of the genome contains repetitive sequences with predominancy of LTR-retrotransposons and unknown elements. Comparative genome analysis of M. chilensis and M. coruscus was conducted, revealing genic rearrangements distributed into the whole genome. Notably, transposable Steamer-like elements associated with horizontal transmissible cancer were explored in reference genomes, suggesting putative relationships at the chromosome level in Bivalvia. Genome expression analysis was also conducted, showing putative genomic differences between two ecologically different mussel populations. The evidence suggests that local genome adaptation and physiological plasticity can be analyzed to develop sustainable mussel production. The genome of M. chilensis provides pivotal molecular knowledge for the Mytilus complex.
