“…Various studies have examined the influence of age on the growth and survival of pearl oysters, including the penguin's wing oyster (Liang et al 2008), black-lip pearl oyster (Fu et al 2010), pearl oyster (Yin et al 2012), and triangle mussel (Xu et al 2011). For example, Liang et al (2008) reported that the survival and retention rates among 2.0year-old penguin's wing oysters were evidently higher than rates for 3.0-and 4.0-year-old oysters.…”

“…In evolution, aging is described as the age-related or progressive decrease in tissue functioning that occurs in all living organisms over time (Flatt 2012). Various studies have documented the effects of aging on the growth, survival, and pearl traits (luster, size, and color) of pearl oysters, such as the pearl oyster (Yin et al 2012), blacklip pearl oyster Pinctada margaritifera (Fu et al 2010), and penguin's wing oyster Pteria penguin and the freshwater triangle mussel Hyriopsis cumingii (Xu et al 2011).

This study evaluated the influences of age on the pearl production performance and innate immune responses of the pearl oyster Pinctada fucata martensii. Two age‐groups (group A: 1.5 years of age; group B: 2.5 years of age) were subjected to a nucleus insertion operation. The immune‐ and antioxidant‐related enzymatic activities and expression levels of immune‐related genes in both groups were evaluated 3 d after the nucleus insertion operation. The survival rate, retention rate, and biomineralization capacity of the groups were examined when the pearls were harvested. The results showed that the activities of alkaline phosphatase, acid phosphatase, superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) and the expressions of the SOD, GPx, heat shock protein 70 (HSP70), and HSP90 genes were significantly higher in group A than in group B 3 d after the nucleus insertion operation (P < 0.05). Group A had a significantly higher survival rate than group B at 3, 7, and 30 d after the operation and at harvest. Group A had a significantly higher retention rate and pearl thickness than group B at harvest. The expression levels of the biomineralization genes for nacrein and pearlin were significantly higher in group A than in group B (P < 0.05), whereas expression of the biomineralization gene for Pif‐177 was significantly higher in group B. Collectively, these results suggested that 1.5‐year‐old pearl oysters have better pearl production performance and innate immune response to nucleus insertion operations, so selecting young pearl oysters to use as host and donor oysters shows promise as a process for improving the quality of cultured pearls.

Freshwater bivalves farming is principally focused on freshwater pearl production in Asia and conservation aquaculture in USA while in Europe is almost completely unknown. High larval mortality is considered the bottleneck in freshwater bivalve larval rearing and methods currently used in marine bivalve larval rearing can be transferred in freshwater mussels. It is likely that probiotics and aquatic microbiology will play a key role also in freshwater bivalves larval rearing. Alternative applications of freshwater mussel rearing should be studied in deep in the future as integrated productions, bioindication projects and utilization of freshwater mussel meal as potential source for fish feeds. The aim of this review is to give a description of potential applications for freshwater bivalve rearing and possible future perspectives.

“…Aquaculture of mussels is a traditional industry that contributes enormously to the economic development of aquatic products. In recent years, however, the impact of various diseases is an increasingly serious problem (Wang et al, 2007;Xu et al, 2011). Increased resistance of bacteria towards antibiotic drugs has stimulated intensive efforts for the discovery and characterization of antimicrobial effectors.…”

ABSTRACT. Antimicrobial peptides (AMPs), of which big defensins are examples, are an important component of the natural defenses of most living organisms, and possess remarkable microbicidal activities. In the present study, using expressed-sequence tag sequences from a cDNA library and RACE, the full-length cDNA sequence of the big defensin gene from the triangle-shell pearl mussel, Hyriopsis cumingii, (HcBD), was cloned. The gene consists of a 5'-untranslated region (UTR) of 166 bp, a 3'-UTR region of 96 bp, and an open reading frame of 342 bp that encodes 113 amino acids, consisting of a 23 amino acid signal peptide and a mature peptide of 90 amino acids with a molecular mass of 12.5 kDa. Amino acid sequence analysis showed that the sequence contained a transmembrane domain and a hydrophobic region. The full-length amino acid sequence showed the highest similarity to an amphioxus (Branchiostoma floridae) sequence (64%), and lower similarities to other known defensins (α-, β-, and θ-defensins, and insect defensins). Expression of HcBD was relatively high in the mantle and blood, lower in other tested tissues, and absent in gill and foot tissues. Real-time quantitative PCR was used to investigate Big defensin gene in freshwater musselHcBD expression in various tissues at different time points after injection of Aeromonas hydrophila. At 4 h post-inoculation, HcBD expression in the mantle, liver, intestine, gill, and foot was greater than in the control, with the greatest expression at 72 h, while at 24 h, expression in the liver, intestine, gill, and foot were at their lowest levels. These results suggest that HcBD might play an important role in the host immune response. This study enriches the basic research on the big defensin family of antimicrobial peptides and lays foundations for further research on antimicrobial peptide expression and relevance to disease defense.
