The simplification of the methodology used in this study allows this method to be used for routine applications and highlights the importance of tissue‐specific analyses for understanding mussel energetic metabolism.…”

“…These methods include the analysis of the lipid and fatty acid composition in adult mussels (Prato et al. ) and the analysis of lipids or glucose in juveniles (Tankersley ; Sim‐Smith and Jeffs ). In contrast, nonlethal methods can be applied for a larger part of a population to obtain more replications (Gustafson et al.…”

Glycogen is a primary metabolic reserve in bivalves and can be suitable for the evaluation of bivalve condition and health status, but the use of glycogen as a diagnostic tool in aquaculture and biomonitoring is still relatively rare. A tissue biopsy combined with a simplified phenol-sulfuric acid method was used in this study to evaluate the inter-and intraindividual variation in the glycogen concentrations among several tissues (foot, mantle, gills, adductor muscle) of the unionid bivalve, the duck mussel Anodonta anatina. This short report documents that individual bivalves differ in the spatial distribution of glycogen among tissues. Sampling of different types of tissues can cause distinct results in the evaluation of energetic reserves at the individual level. At the same time, spatial variability in glycogen content has the potential to provide a more detailed evaluation of physiological conditions based on tissue-specific glycogen storage. The results obtained and the simplified methodology provide a new opportunity for researching the energetic reserves and health status of freshwater mussels in various applications.

“…3 in the present study, Buchanan & Babcock 1997). Losses of juvenile mussels from aquaculture substrata could also be due to other factors that include variations in genetics and fitness among individuals (Phillips 2002, Alcapán et al 2007, Sim-Smith & Jeffs 2011, disease (Jones et al 1996), predation pressure (Hayden 1995, Peteiro et al 2010, biofouling (Fitridge et al 2014) and stressors associated with the relay of juveniles from the hatchery or wild collection sites to the nursery farm location that might increase mortality or trigger secondary settlement (Webb & Heasman 2006, Carton et al 2007). Quantifying the relative importance of the causes of loss has not been satisfactorily achieved in this and other studies and remains an important research priority.…”

“…Furthermore, the retention of juvenile P. canaliculus on aquaculture growing substrata, such as fibrous nursery ropes, can be very poor, with losses that range from 50 to 100% (Jeffs et al 1999, Webb & Heasman 2006, Hayden & Woods 2011). Consequently, a few studies have specifically addressed the causes of low retention, focussing on methods of determining the quality of juveniles captured from the wild (Webb & Heasman 2006, Sim-Smith & Jeffs 2011, impacts on fitness and behaviour that can occur during transport or due to poor handling (Webb & Heasman 2006, Carton et al 2007) and environmental conditions during early production (Alfaro 2006c, Carton et al 2007, Hayden & Woods 2011. However, the issue of retention is complex and far from understood, largely due to the small number of studies that have addressed this problem.…”

The majority of juvenile seed mussels are lost in aquaculture production. Understanding the causes of the losses of seed mussels is critical to reducing uncertainties in mussel aquaculture production. One major cause of loss appears to be the secondary settlement behaviour of mussels, which is thought to be a behavioural process by which larger juveniles can safely recruit among adults. This implies that once a juvenile mussel has settled among adults, there is either some impetus to remain or other positive interactions that promote increased survival. In this study, 2 densities (5 and 20 per 45 cm experimental rope) of adult green-lipped mussels Perna canaliculus were deployed alongside juvenile seed mussels to test whether this enhanced the retention of the juveniles in a typical suspended culture. Adult shells were also deployed to ascertain whether any effects were due to the physical presence of the mussels or the influence of their biological functioning. The presence of adult mussels or shells did not increase the retention of juvenile P. canaliculus, but small-scale movements of juveniles were increased by the addition of 20 live adult mussels per experimental rope. However, the presence of adult mussels and mussel shells on experimental ropes greatly increased the abundance of biofouling organisms. While the addition of live adult mussels or shells failed to provide a simple tool for increasing retention of seed mussels on aquaculture lines, they offer new insights into the identity and ecology of key biofouling organisms that can be problematic in mussel aquaculture production.
