Grazing of Natural Particulates by Bivalve Molluscs: A Spatial and Temporal Perspectiveo tidal cycle changes in the seston flux. Field observations have shown that the processing of phytoplankton, organic detritus and inorganic particulates by shellfish beds results in kilometer scale effects on particle concentration which can be simulated by computer modelling. A four-year study (19

Invertebrate Predators and their Role in Structuring Coastal and Estuarine Populations of Filter Fee predator is likely to be most pronounced amongst specialist predators which feed on only a restricted number of prey species, and perhaps least pronounced amongst generalist predators in which the diet includes a much broader spectrum of alternative prey types. Even so, generalist predators can hav

The Impact of Bird Predation on Marine and Estuarine Bivalve Populations: A Selective Review of Pattas wintering areas (see Davidson and Pienkowski 1987; Boyd and Pirot 1989 and references therein). For some species they also form important breeding sites. Birds are attracted to these habitats because of the huge amount of food present that can be exploited easily as the tidal flats are exposed at

The Role of Bivalve Filter Feeder Material Fluxes in Estuarine Ecosystemsd from and releasing waste materials to the overlaying waters. The surrounding shallow tidal waters provide a habitat for growing phytoplankton and an environment for nutrient recycling. In essence, these systems are natural “feed lots” with the herbivorous bivalves playing the same role as large ma

Bivalve Feeding and the Benthic Boundary Layerytilidae in most oceans (see Paine 1984). This dominance may be related to at least two important aspects of their ecology the sestonic nature of their food and their sessile mode of life. The food of seston feeders is produced in a three-dimensional environment which flows over the animals. Under f

Perspectives on Field Studies and Related Biological Models of Bivalve Growth and Carrying Capacity grown exponentially in the last decade (Hickman 1989; Mallet 1989). Acceptable culture sites are limited due to habitat suitability, road access, and competing recreational or commercial use such as wild fisheries. As available culture space becomes filled up with stock, there may be a depression o

A Set of Models to Investigate the Role of Benthic Suspension Feeders in Estuarine Ecosystemsities can be the key mortality factor for the phytoplankton. It is not unusual that the daily filtration capacity of the suspension feeders is in the order one fifth to one third of the total system water volume, thus imposing on the phytoplankton a mortality rate in the order of 0.20 to 0.33 d.

Why Carrying Capacity Models are Useful Tools for Management of Bivalve Molluscs Cultureans have been proposed to regulate the cultivated biomasses in order to fit the carrying capacity of the different ecosystems (Heral et al 1990; Heral, 1991). In areas where new aquaculture of molluscs is beginning, oyster or mussel farmers need to know how large the extension of the culture could b
