“…Rajesh et al (2001) also arrived at a similar conclusion for three Indian bivalves (Perna veridis, Crassostrea madrasensis, and Paphia malabrica). However, for the oyster, laboratory-based experiments have demonstrated that clearance rate decreases with POM (Barillé et al 1997). The observed pattern of elevated clearance rates obtained in the present study reflects the rapid decrease in POC during the first 3 h after feeding, regardless of the initial quantity (Fig.…”

Abstract:In coastal ecosystems, variations in food quantity may have significant effects on the clearance and ingestion rates of suspension-feeding bivalves. In this study, clearance rates and ingestion efficiencies were determined for Japanese scallop (Patinopecten yessoensis) juveniles (60.6 4.5 mm in shell height) under laboratory conditions. Scallops were kept individually in glass beakers at 15°C and fed with different cell numbers of Pavlova sp. (0.8 to 57.60 10 6 cells) to provide a wide range of food quantity as particulate organic carbon (POC). Clearance rates (CR) and ingestion efficiencies (IE) were estimated by monitoring POC concentration over a two-day period, and from 2 to 14 days of feeding, respectively. Both CR and IE were significantly influenced by POC concentration. CR ranged from 15.8 to 38.5 mL ind 1 h 1 (or 8.9 to 49.6 mg C h 1 g dry weight ). It is concluded that particle filtration rates by juvenile scallops are related to food quantity, as suggested by both field and laboratory-derived feeding rates.

“…Variations in phytoplankton biomass (expressed as Chl-a level), POM and TSS, could partially be associated with the diverse amount and type of nutrient material flowing from inland human activities to the cultivation sites (Ruíz-Luna & de la Lanza-Espino, 1999). Barillé et al (1997) mention that C. gigas has the capacity to select food depending on its abundance as a feeding mechanism, which could partially explain the oyster growth. The salinity drop in December and March presented in Ahome and Guasave farms was possibly caused by a dilution effect from agriculture and aquaculture drainages combined with the mean shallow depth at both places.…”

ABSTRACT. Diploid and triploid Crassostrea gigas oysters were cultivated at three farms (Guasave, Navolato and Ahome) in Sinaloa, Mexico, to evaluate their growth and economic performances. Growth rate and survival of oysters were compared in long-line cultivation and were mostly affected by water parameters rather than ploidy or their interaction. The highest growth rates for shell length (8.01 mm month ) were obtained for the Ahome/triploid group. Survival differed significantly from 98.6% for the Guasave/triploids to 76.7% for the Ahome/diploids. After the first production cycle, more than 80% of production costs represent the purchase of cultivation equipment and salaries contributed with around 9%. The Guasave farm produced the highest profits (US$8,053.71 diploids, US$8,182.19 triploids). Use of diploids starting the production cycle on October-November to avoid mortality and improve final profit is recommended.

“…Suspended sediment may be particularly important, influencing turbidity and light, and the feeding efficiency and biodeposit production of suspension feeders (Barillé et al 1997, Hawkins et al 1999. Suspended sediment loads may also determine the distributional limits of benthic macrofaunal suspension-feeders within the estuary (Quijón et al 1996, Ellis et al 2002.…”

Benthic nutrient fluxes (BNF) can supply 30 to 100% of the nutrient requirements of benthic and pelagic algae in an estuary, and can, thus, potentially sustain benthic and pelagic primary production within the estuarine food web. While BNF can be influenced by microbial processes, epibenthic suspension-feeding bivalves have the potential to alter fluxes by their influence on the community composition of surrounding macrofauna and benthic boundary conditions, and their feeding activities. In Mahurangi Harbour, New Zealand, the large suspension feeding pinnid Atrina zelandica (hereafter referred to as Atrina) occupies large areas of the harbour floor. Consequently, Atrina have the potential to substantially influence the BNF and, thus, primary production, and the food supply to the filter feeding community within the harbour, including the rack-farmed Pacific oyster aquaculture industry. Mahurangi Harbour is almost always isohaline, but exhibits a strong gradient in suspended sediment concentration, which declines from head to mouth. As Atrina increase their rate of pseudofaeces production with increases in suspended sediment concentration, we conducted in situ light and dark paired benthic chamber experiments with and without Atrina at 4 stations along this turbidity gradient, to determine their effect on BNF. Our results showed substantially greater BNF from Atrina beds than bare sediments. We also found greater net BNF (difference between Atrina beds and bare sediment) in the less turbid water under dark conditions, but enhanced water column nutrient supply in the more turbid water in light, due to Atrina excretion of ammoniacal nitrogen . On an areal basis, we estimate that BNF from Atrina beds may account for up to 80% of the nutrient supply for pelagic primary production and, thus, they are of major importance to the sustainability of aquaculture in this harbour.

However, the presence of large benthic animals may also stabilise the sediments, and affect the composition and functioning of macrofaunal communities (Cummings et al. 1998, Ellis et al. 2000, Norkko et al. 2001, Reise 2002. Abundant suspension-feeders may build loose hummocks, multi-species epibenthic thickets or solid reefs, accommodating diverse epibenthic assemblages. Their raised and rough surfaces alter benthic boundary conditions (Green et al. 1998) and, hence, turbulence (Reise 2002), while their biodeposits may enrich the sediments and smother the microphytobenthos.
