“…in press). This is consistent with previous ideas relating seston depletion to the balance of tidal food renewal and removal due to suspension feeding (Dame & Prins 1998), as well as previous field studies of raftcultured mussels in Spain (Camacho et al 1995), and bottom-cultured clams in the USA (Grizzle & Lutz 1989). Dowd (2003) modelled seston dynamics in Tracadie Bay and predicted that seston flux differed by an order of magnitude between inner and outer parts of the bay.…”

“…Similarly, studies of seston depletion have been made at localized small-scales (Newell 1990, Fréchette & Grant 1991, Navarro et al 1991, Pilditch et al 2001, and indicate that the concentration as well as the delivery of food determines the capacity of a location to support growth. At bay-wide scales, Dolmer (1998) measured shell growth in 164 Camacho et al (1995) conducted 90 d mussel growth experiments at 3 locations in a Spanish estuary and found that phytoplankton availability controlled live weight increase. The long-term growth response of cultured mussels associated with strong environmental gradients in estuaries and bays has not been addressed despite the potential importance of these gradients to mussel production.…”

Spatial growth variation of experimentally cultured blue mussels Mytilus edulis in Tracadie Bay, Prince Edward Island, Canada, was consistent in both years of a 2 yr study. The spatial pattern displayed reduced tissue growth along a gradient of decreasing tidal exchange from the inlet mouth to the inner estuary. There was no indication of persistent spatial differences in seston concentration among stations. The data imply that the flux of food (expressed as the product of concentration and current speed) controls the spatial variation in growth, with decreasing flux from the outer to inner bay. Growth trajectories analysed by polynomial regression differed between years despite spatial similarities within each year. Results of multiple regression analyses explaining mussel growth suggested that temporal variability in seston characteristics was more important in explaining growth than annual mean seston levels. Chlorophyll a and meat weight showed similar patterns of increase during 1998. In 1999, higher summer temperatures were more important in determining upper limits of growth, with later growth stimulation apparently in response to an autumn phytoplankton bloom. The pattern of spatial variability in mussel growth, representing decreased growth rates in the inner relative to the outer bay, provided evidence that the density of mussels in Tracadie Bay was exceeding the food supply.KEY WORDS: Mussels · Mussel growth · Food availability · Phytoplankton · Aquaculture · Carrying capacity Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 297: [157][158][159][160][161][162][163][164][165][166][167] 2005 There are many scales at which food limitation can affect the growth of cultured bivalves. High density at a local scale (e.g. within socking sleeves) may lead to reduced growth of interior bivalves (Parsons & Dadswell 1992, Côté et al. 1994. Seston depletion resulting from the distribution of bivalves on longlines may also affect their growth in the centre of a farm (Pilditch et al. 2001). A large-scale gradient in mussel growth can occur as a result of the interaction between the distribution of phytoplankton, the filtration capacity of local populations, and water circulation patterns in heavily cultured embayments (Dolmer 2000). Seston depletion might be expected to be most severe in the innermost part of a bay if the majority of the food supply is from incoming tides (Dowd 2000). There are surprisingly few studies of spatial variation in growth of cultured bivalves despite the potential importance of this factor to shellfish growth.This study investigated the relationship between blue mussel growth and food supply within an intensely cultured embayment in PEI. Mussel growth was measured coincident with monitoring seston concentrations and temperature at 5 geographically distinct locations within the embayment. Growth trajectories were described statistically and the interaction between mussel growth, environmental variables, and location examined. In a...

“…This could be due to the major linear importance of the POM variable in this specific analysis that varied between 42 and 73%, (see Tables 2 and 3). In this sense, several studies have shown that the differences in the biochemical composition of mussel populations located in zones with distinct environmental conditions were due to qualitative and/or quantitative differences in the food availability of phytoplanktonic origin (PÉREZ-CAMACHO et al, 1995;FERNÁNDEZ-REIRIZ et al, 1996;OKUMUS;STIRLING, 1998).…”

García et al.: Comparative culture of P. perna and P. viridis 249Comparative performance of the mussels Perna perna and Perna viridis, cultivated at four different depths This study aims to evaluate the effect of environmental variability on the growth and survival of the subtropical and tropical mussels Perna perna and Perna viridis at four different culture depths in the Gulf of Cariaco during an annual cycle. Juveniles of P. perna (39.1±1.88 mm in shell length) and P. viridis (36.7±1.87 mm) were sown on nylon ropes (3/4") and suspended from a raft at 1, 3, 6 and 9 m depths. Every six weeks, three replicates of each species were sampled (10 individuals per replicate) at each depth. Growth parameters were determined: mass and shell length, dry mass of soft tissues as well as fouling and survival rates. Temperature, transparency, chlorophyll a, oxygen, salinity and particulate organic and inorganic matter were recorded at each culture depth for the purpose of relating growth and survival to environmental change. The results show that the growth of both species was linked to the environment, especially with regard to the influence of the food and temperature. A period of stagnant growth of P. perna was associated with the higher temperature and lower phytoplankton biomass that is characteristic of the season with prevalent water column stratification (August-November 2007). By contrast, the growth of P. viridis did not stagnate, although it was gradual and relatively lower. At the end, P. perna achieved higher growth rates than P. viridis. Possible culture strategies to improve the production of both mussel species are discussed. AbstrAct

“…Water temperature may strongly covary with seasonal phytoplankton abundance and/or chlorophyll a (Kautsky 1982;Toro et al 1995;Toro 1996), thus making it difficult to draw any conclusion about the importance of temperature or chlorophyll abundance in regulating growth rate. Strong positive effects on growth would be expected from an increment in the chlorophyll abundance (Page & Hubbard 1987;Camacho et al 1995). This might contribute to an explanation where high growth rates during spring cannot be accounted for by temperature or POM availability (Hawkins et al 1996;Navarro et al 1997).…”

The phytoplankton community of the Putemun Channel (southern Chile) and its correlation with some environmental variables is analysed in this paper. Samples were collected on a monthly basis from May 1991 to May 1993. A total of 121 phytoplanktonic species were identified. The phytoplankton cell abundance ranged between 3.5 × 10 4 cells/litre and 11.2 × 10 6 cells/litre. The phytoplankton community was characterised by the dominance of diatoms. An inverse relationship between temperature and species diversity was observed. A significant correlation, after excluding tychoplanktonic benthic forms, was found between chlorophyll a, cell abundances, and temperature. The influence of biotic and abiotic variables on oyster (Ostrea chilensis (Philippi 1845)) growth was analysed. The instantaneous growth rate was found to be positively correlated with both temperature and phytoplankton abundance, whereas significant negative correlation between growth and amount of particulate inorganic matter was found.
