“…Anyway, parental contributions were rather evenness both in OSH and WZH, which suggests that the reproduction protocol, at least regarding the maturation condition of parents, seems suitable, and so the main point to be considered in future restocking programs would be the number of batches and progenitors per batch to maintain diversity. (Di et al, 2015;Gallaga-Maldonado et al, 2020;Maynard et al, 2016), sometimes involving specific immune genes, such as the histocompatibility complex (MHC; Kekäläinen et al, 2009;Penn et al, 2002). It is important to note that the term resistance applied until now in this and previous studies related to bonamiosis infection is rather inaccurate, as the response to the parasite may be related both to resistance against infection and the ability to survive once infected (tolerance) (Holbrook et al, 2021) in the wild, associated with their typical large effective population sizes (Gutiérrez et al, 2017;Hu et al, 2021;Vera et al, 2022;Zhong et al, 2017).…”

European flat oyster (Ostrea edulis) is an ecologically and economically important marine bivalve, that has been severely affected by the intracellular parasite Bonamia ostreae. In this study, a flat oyster SNP array (~14,000 SNPs) was used to validate previously reported outlier loci for divergent selection associated with B. ostreae exposure in the Northeast Atlantic Area. A total of 134 wild and hatchery individuals from the North Sea, collected in naïve (NV) and long‐term affected (LTA) areas, were analysed. Genetic diversity and differentiation were related to the sampling origin (wild vs. hatchery) when using neutral markers, and to bonamiosis status (NV vs. LTA) when using outlier loci for divergent selection. Two genetic clusters appeared intermingled in all sampling locations when using outlier loci, and their frequency was associated with their bonamiosis status. When both clusters were compared, outlier data sets showed high genetic divergence (FST > 0.25) unlike neutral loci (FST not ≠ 0). Moreover, the cluster associated with LTA samples showed much higher genetic diversity and significant heterozygote excess with outlier loci, but not with neutral data. Most outliers mapped on chromosome 8 (OE‐C8) of the flat oyster genome, supporting a main genomic region underlying resilience to bonamiosis. Furthermore, differentially expressed genes previously reported between NV and LTA strains showed higher mapping density on OE‐C8. A range of relevant immune functions were specifically enriched among genes annotated on OE‐C8, providing hypotheses for resilience mechanisms to an intracellular parasite. The results suggest that marker‐assisted selection could be applied to breed resilient strains of O. edulis to bonamiosis, if lower parasite load and/or higher viability of the LTA genetic cluster following B. ostreae infection is demonstrated.

“…Se utilizó una línea seleccionada desde 1998 para crecimiento y SC (CRE), y otra línea con antecedentes de resistencia a SMB (RES). Las familias consideradas de cada línea en este estudio tuvieron un máximo de 25% de genes de la otra línea (Gallaga-Maldonado et al, 2020), y se analizaron de manera independiente. Para la línea CRE se analizaron 7,679 registros procedentes de apareamientos entre 49 padres y 69 madres (familias).…”

Este estudio tuvo como objetivo estimar la interacción genotipo por ambiente para peso corporal (PC) y supervivencia a cosecha (SC), en presencia y ausencia de Síndrome de Mancha Blanca (SMB) en dos líneas genéticas de Penaeus vannamei (Crecimiento -CRE-y resistencia a SMB -RES-). La heredabilidad para PC en la línea CRE fue 0.05 ± 0.16 en presencia de SMB y 0.35 ± 0.15 en ausencia, mientras que para la línea RES fueron 0.26 ± 0.07 y 0.49 ± 0.08 en presencia y ausencia de SMB, respectivamente. Las correlaciones genéticas para PC entre ambientes fueron -0.17 ± 0.60 para CRE y 0.89 ± 0.09 para RES. La heredabilidad para SC en CRE fue 0.01 en ambos ambientes y la correlación genética no fue estimable, mientras que, para RES, las heredabilidades fueron 0.06 ± 0.04 y 0.11 ± 0.06 en ausencia de y presencia de SMB, respectivamente, adicionalmente, la correlación genética no fue significativa. Aunque el modelo lineal sugiere una interacción genotipo por ambiente, los estimados proponen independencia de la misma característica entre ambientes y, las correlaciones entre características para la línea de resistencia proponen seleccionar de manera independiente las características cuando SMB esté presente.

“…On the other hand, since 2013, higher resistance lines have been developed with shrimp broodstock imported from Ecuador as a strategy to reduce mortality rates caused by white spot syndrome virus (WSSV) (Gallaga-Maldonado et al, 2020;Perez-Enriquez, Robledo, Houston, & Llera-Herrera, 2018). Nevertheless, the genetic selection processes can influence important physiological and metabolic processes (Grijalva-Chon, Izaguirre-Castro, Castro-Longoria, López-Torres, & Hoyos-Chairez, 2013), such as shrimp growth and immune response.…”

Two shrimp genetic lines (LGR: faster growth and LWR: higher white spot syndrome virus resistance) were evaluated with six dietary treatments containing different sources (animal and plant), and three protein levels (low, medium and high). A five-week bioassay was conducted using Litopenaeus vannamei with an average initial weight of 2.08 ± 0.06 g to determine the influence of the genetic line, protein source, and protein level on the weight gained per week, survival, and expression of immune-related genes. The overall mean of weight gain was 1.02 g/week for LGR and 0.71 g/week for LWR. Survival was 71.7% for LGR and 78.9% for LWR. The genetic line influenced weekly weight gain and survival while a significant interaction between genetic line, protein source, and protein level, influenced the expression of immune-related genes of shrimp. The data suggested that a diet containing plant-based protein (30-35%) at medium level was sufficient to obtain adequate values of weekly weight gain and survival without affecting
