“…Obtained values of the excreted ammonia are consistent with the results reported by Widdows and Johnson (1988), Navarro and Gonzalez (1998) and James, Weatherhead, and Ross (2001). It should be mentioned that Bayne and Scullard (1977b) investigating specific dynamic action of the mussel M. edulis in experiments in which shellfish were fed with flagellate T. suecica found an increase in AE 24 to 30 hours after the feeding in almost a half of the experiments.…”

Bearded horse mussel and Noah's ark shell are sometimes observed to live together in groups. Oxygen consumption, ammonia excretion and clearance rate were investigated on these species under laboratory conditions considering different size of individuals divided into three size groups (less than 25 mm; 25 to 50 mm and larger than 50 mm). Body size of both species significantly influenced oxygen consumption, ammonia excretion and clearance rate of the Noah's ark shell. In both species, respiration and clearance rate decreased with body size while excretion rate increased with body size. For Noah's ark shell groups of 25 to 50 mm and smaller than 25 mm, the atomic ratio between oxygen consumption and ammonium excretion i.e. O:N ratio was detected to be greater than 30. The same applies to a group of the bearded horse mussels smaller than 25 mm. Animals of both species larger than 50 mm have O:N ratio smaller than 30 indicating use of proteins as metabolic substrate, compared to use of lipids and carbohydrates in younger animals.

“…These results concur with studies that show that filtration/removal efficiency decreases for most bivalves within a size range of around 1 to 7 μm, depending on the bivalve species (Ward & Shumway 2004). James et al (2001) reported P. canaliculus could remove particles efficiently down to 5 μm. The results of Møhlen-berg & Riisgård (1978) and Riisgård (1988) suggest that retention efficiency is, in part, dependent on the morphology of the laterofrontal cilia of the ctenidium.…”

“…Perna canaliculus can efficiently remove and ingest organisms as small as 5 μm (James et al 2001) and more recent evidence indicates that they can also capture and ingest larger particles, including zooplankton (Zeldis et al 2004). Studies of other bivalves have demonstrated that, as well as food quality, size and shape can be a significant criterion by which particles can be preferentially rejected as pseudofaeces before ingestion (Defossez & Hawkins 1997), although there is still debate whether size alone is a criterion for rejection (Ward & Shumway 2004).…”

Phytoplankton biomass alone cannot predict growth and condition in the mussel Perna canaliculus. This study investigates whether food selection processes, low removal rates of small picophytoplankton-sized particles (0.2 to 2 μm) or additional heterotrophic food sources such as microzooplankton and bacteria may help explain this observation and therefore aid in predicting growth and condition in P. canaliculus. Three grazing experiments were run at different times of the year, using naturally varying planktonic assemblages. P. canaliculus did not feed efficiently on picophytoplankton or bacterial particles and higher filtration rates were always observed on larger phytoplankton (> 2 μm). Much of the 0.2 to 2 μm size fraction, whether heterotrophic or autotrophic, was not directly utilised for mussel growth. In terms of phytoplankton biomass, grazing and ingestion was often highest on naked flagellated cells. Results indicated that selection of some phytoplankton for ingestion was based on food quality, with both small and large naked flagellated cells with high carbon content often preferred over other morphotypes. P. canaliculus also supplemented its diet with heterotrophs, heavily grazing a range of microzooplankton. Grazing overall showed selection for naked flagellated or ciliated microzooplankton with high carbon content. The results indicate that rather than directly accessing picophytoplankton and bacteria, P. canaliculus accesses these populations through the food web by grazing upon microzooplankton, mixotrophic algae and, potentially, aggregates. This study adds to our ability to predict mussel condition by identifying key food sources for the growth of P. canaliculus.KEY WORDS: Phytoplankton · Size structure · Mussels · Picophytoplankton · Pelorus SoundResale or republication not permitted without written consent of the publisher

Biofouling on Greenshell™ mussel (Perna canaliculus) farms: a preliminary assessment and potential implications for sustainable aquaculture practices

2011

Greenshell TM mussel (Perna canaliculus) culture is the primary aquaculture industry in New Zealand. However, our knowledge of biofouling on Greenshell TM mussel farms, and its contribution to farm ecotrophic effects, is poor. We conducted a preliminary study of biofouling accumulation at two Greenshell TM mussel farms during Intermediate and Final seed on-growing stages (each of 6 months duration) with sampling of mussel ropes at 0, 3, 5 and 6 months during each on-growing stage. A diverse range of biofouling organisms (71 distinct taxa) accumulated on mussel ropes, with biofouling biomass dominated by suspension-feeding organisms (*88% of biofouling biomass) such as other bivalves, ascidians and, to a lesser degree, bryozoans. Biofouling biomass increased with culture time, varied between farms and was generally greater at 2 m than at 8 m depth. After 6 months, biofouling organisms on average comprised 54% of the total rope biomass. The reseeding of ropes between Intermediate and Final seed crops reduced the amount of non-Greenshell TM mussel biofouling. However, after 6 months, non-Greenshell TM mussel biofouling on average still comprised 15% of the total rope biomass. To evaluate potential ecotrophic effects of biofouling on Greenshell TM mussel farms, we compare the clearance rates of Greenshell TM mussel longlines based on Greenshell TM mussels alone and when combined with the two dominant biofouling species observed in our study (the mussel Mytilus galloprovincialis and the ascidian Ciona intestinalis). Our study shows that accumulated biofouling biomass on Greenshell TM mussel ropes can be significant and recommends further investigation as to actual ecotrophic effects of biofouling to ensure sustainable mussel farm practices.
