“…In this study, the term 'feeding rate' refers to the net result of various feeding processes: filtration, ingestion, absorption, rejection and selection. The feeding rates (Table 1) have been adapted from Hawkins et al (1999) and calculated using the biodeposition method as discussed by Iglesias et al (1998). The term 'filtration rate' (FR) has been used even though technically Perna canaliculus is a suspension feeder, not a filter feeder (Shimeta & Jumars 1991).…”

“…The biodeposition method provides results equivalent to those from more conventional methods used for estimating feeding rates in closed or flow-through systems, providing the methods are followed exactly (Riisgård 2001). The main advantage of this method is that feeding responses are time-integrated and are therefore less affected by short-term variations in feeding behaviour (Iglesias et al 1998).…”

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

-1 , respectively. The biodeposition rates of 2-yr-old scallops were almost double these values. Sedimentation rates at scallop culture sites averaged 2.46 times that at the reference site. Theoretically, the total water column of the bay could be filtered by the cultured scallops in 12 d, with daily seston removal amounting to 64%. This study indicated that filteringbiodeposition by suspension-cultured scallops could exert long-lasting top-down control on phytoplankton biomass and other suspended material in the Sishili Bay ecosystem. In coastal waters subject to anthropogenic N and P inputs, suspended bivalve aquaculture could be advantageous, not only economically, but also ecologically, by functioning as a biofilter and potentially mitigating eutrophication pressures. Compared with distribution-restricted wild bivalves, suspension-cultured bivalves in deeper coastal bays may be more efficient in processing seston on a basin scale.

“…Feeding rates and efficiencies (see Table 1 for abbreviations) were measured using the 'biodeposition method' as described by Iglesias et al (1998), Hawkins et al (1998) and Bayne et al (1999). Oysters were placed individually in specially constructed feeding trays and directly supplied with water pumped from the immediate vicinity of the experimental trays.…”

This field study had 2 objectives: (1) to test predictions from laboratory studies on growth and feeding behaviour in a comparison of 2 oyster species from the same estuary in NSW, Australia; and (2) to compare the feeding behaviour of these oysters with published accounts of other bivalve species from elsewhere. The predictions were that Pacific oysters Crassostrea gigas would feed and grow more quickly along with a greater metabolic efficiency than Sydney Rock oysters Saccostrea glomerata. Measurements were made at 3 sites in the Port Stephens estuary, NSW, and the predicted differences between species were confirmed. For both species, growth was quicker from March to May than from May to July (1999). Feeding was also faster in March and May than in July. Absorption efficiency was maintained at a relatively constant level over the experimental period by a compensatory response to changes in the organic content of the ingested material. Selection and absorption efficiencies for nitrogen altered over time, holding nitrogen absorption relatively independent of the nitrogen content of the food. Simple equations were fitted to the data to describe feeding behaviour as a function of properties of the diet, and these equations used to compare these oysters with relationships for other bivalves in the literature. A few such equations may be used to predict net absorption of food energy by oysters in the field, based on measurements of food only. At one rather coarse level, there are basic similarities between bivalve suspension feeders regarding feeding behaviour and its relation to growth. At a more detailed level, differences in physiological responses to diet may help in the interpretation of differences in growth, such as have been observed here for 2 oyster species growing in the same habitat. The competitive advantage enjoyed by C. gigas over S. glomerata is due to faster rates of feeding, particularly at higher food concentrations, and greater metabolic efficiencies of both feeding and growth.KEY WORDS: Oysters ⋅ Feeding ⋅ Growth ⋅ Metabolism ⋅ Carbon ⋅ Nitrogen Resale or republication not permitted without written consent of the publisher
