“…Most of the mussel seed does not survive the cycle from seeding to harvest. Average survival of SMC-seed or seed relayed from wild mussel beds in autumn over the culture cycle is 8 and 15 %, respectively (Capelle et al 2016). A substantial part of the losses is associated with seeding (Theisen 1968;Capelle et al 2014Capelle et al , 2016.…”

“…Losses on culture plots associated with or following seeding are clearly density dependent (Gascoigne et al 2005;Capelle et al 2014Capelle et al , 2016. Seeding practice in bottom culture leads to a highly heterogeneous distribution of mussels on culture plots, with high mussel densities within the space occupied by mussels (Capelle et al 2014).…”

Mussel losses peak after relaying seed on culture plots. The present paper is an attempt to examine the role of shore crab predation and initial mussel density on mussel losses in mussel bottom culture using an intertidal culture plot as a case study. Because of their small size and loose attachment, mussels are particularly vulnerable to predation at this stage, as well as to handling stress and intraspecific competition. In the experimental field plots (1 9 1 m) in the intertidal Oosterschelde, three different densities (1, 5 and 10 kg m -2 ) of mussel seed are laid, with half of the experimental plots protected from predation by means of exclosures. Duration of the experiment was 5 weeks (AugustSeptember 2012) post-seeding. Protection was the major factor accounting for biomass production, followed by mussel density. Loss rates increased with mussel density, both in the exclosures and in the exposed plots. Losses in the exclosures with the lowest density were still 45 %. There are indications that handling stress prior to the start of the experiment played a major role in these losses. At the higher densities in the exclosures, losses increased to 72.1 % and were not significantly different between 5 and 10 kg m -2 . About one-third of the total loss (32.6 %) was attributed to shore crab predation. development during the experimental period was followed and was found to be a slow process that was insufficient to protect mussels from crab predation at the sheltered experimental location.

Growing seed mussels (spat) to larger sizes in single‐seed nursery culture systems prior to seeding onto coastal mussel farms is an effective approach for greatly reducing costly spat losses during this stage of mussel aquaculture. However, the production of single‐seed mussel spat in nursery culture systems relies on first separating spat from the settlement substrata to which they are attached, whether spat are settled in a hatchery or gathered from the wild. This study sought to determine whether chlorination could be an effective approach for separating wild Greenshell mussel (Perna canaliculus) spat from beachcast macroalgal material (Kaitaia spat material) harvested from a beach in northern New Zealand. The results demonstrate that chlorination (i.e. in solutions of up to 0.625% sodium hypochlorite) is a highly effective approach for separating spat, resulting in the detachment of up to 94.6% in one treatment without increasing mortality relative to controls. The effectiveness of chlorination was modulated by spat density, with increasing spat densities, lowering rates of detachment. While chlorination is effective at separating small spat (i.e. successfully separating 72.4% of spat <750 μm in shell length) overall spat densities, further investigation is required to determine how to effectively separate larger spat (i.e. with chlorination only successfully separating 21.5% of spat >750 μm). The high survival (relative to the control treatments) also suggests that chlorine concentrations and exposure durations could be increased from those used in this study. These results demonstrate that chlorination can be used to separate spat from substrate prior to their transfer to nursery systems for ongrowing, paving the way for such approaches for reducing spat losses to be integrated into the aquaculture production cycle.
