| The main life history characteristics, ecology and fishing interest of bivalve and gastropod species from the Argentine Sea are described. Exploited bivalve species are: mussel Mytilus edulis platensis, cholga Aulacomya ater, tehuelche scallop Aequipecten tehuelchus, Patagonian scallop Zygochlamys patagonica. Bivalve species irregularly exploited are: yellow clam Mesodesma mactroides, purple clam Amiantis purpurata, hard shell clam Ameghinomya antiqua and wedge shell Donax hanleyanus. It is also presented information on species of potential interest: clams Eurhomalea exhalbida and Pitar rostratus, half naked pen shell Atrina seminuda, 'geoduck' Panopea abbreviata, razor shells Solen tehuelchus, Ensis macha, Tagelus plebeius, and flat oyster Ostrea... |

| Starting with the major issues of the recent World Conference on Aquaculture, organized in 1981 jointly by the European Mariculture Society and the World Mariculture Society, the paper indicates a number of new and appealing maricultural technologies in shellfish and fish farming. It is postulated that several of the techniques described will have a far-reaching impact on maricultural production in the next decade. Special attention is given to the potential of the mass production of brine shrimp <i>Artemia</i> in extensive and intensive operations, and in particular to its key role in vertically integrated aquaculture. |

| Nematodes are probably the most abundant metazoans in the biosphere and of very great importance to man. As parasites of man they are responsible for disease in hundreds of millions of people and an estimated eight billion nematodes are enjoying food, warmth and shelter in human intestines today; <i>Ascaris lumbricoides</i> is, after the viruses responsible for diarrhoeal disease, the second most infectious organism in the world, about a quarter of the world's population being infected (Ash, Crompton & Keymer, 1984). Plant-parasitic nematodes cause considerable damage to crops and many species are vectors of soil-borne viruses. Today, plant nematology is one of the most vital fields in agricultural research and is studied in many university... |

| The hyperbenthos is a term applied to the association of small animals living in the water layer close to the sea bed. The species composition of the hyperbenthos is distinctly different from that of other benthic and planktonic groupings, and includes endemic species, planktonic species derived from their downward extensions (often with seasonal periodicity) and endo- or epibenthic species as they emerge into the water column (usually in diel cycles). In nearly all marine ecosystems investigated to date, there is a general increase in the biomass at the benthic boundary layer (hyperbenthon) relative to the water column immediately above it, yet the zone and its fauna remain relatively poorly studied. Sampling these often highly mobile animals is not easy... |

| Recent data and opinions on meiofaunal ecology are briefly reviewed; and from scattered data, the place of turbellarians in the meiobenthic community is discussed. Turbellarian diversity is of the same magnitude higher in sandy habitats than in muddy bottoms. In sand, turbellarian diversity is of the same magnitude as that of other important meiofaunal taxa, while densities range between 7-25% of the total meiofauna. Mean individual turbellarian dry weight seems to be four times that of nematodes and in sandy habitats turbellarian biomass may be equal to or exceed that of nematodes. Most turbellarian species may be considered as predators and in this respect may take the place occupied by macrofaunal species in muddy sediments. |
