The utility of biochemical parameters as pollution indicators in fishes with special reference to applicability, feasibility, specificity, and sensitivity is summarized from the currently available literature.

A definite explanation for the high Cd concentrations in natural populations of Haiobates spp. is still lacking. In sea-skaters from the Galapagos Islands region, Cd was clearly taken up into the body, not merely adsorbed, but was not concentrated above ambient levels. Inhaled aerosols, a high daily drinking rate, Cd-enriched food, and binding sites for storage of the metal are all considered as possible contributors to the high Cd concentrations in these oceanic insects. lnstitut fiir Meeresforschung Bremerhaven, Germany, F.R.G.

Seawater enriched with inorganic P ( -< 900 ~tg/L), N (<2600 ug/L) and domestic sewage were passed through columns of sandy sediment from a Hong Kong estuary. Effluent concentrations were 18 ug P / L and 5 ug N / L irrespective of influent concentrations. Phosphate removal was probably due to physical adsorption since biocides had no effect. Numbers of bacteria, meiofauna and particulate organic C decreased, but numbers of nematodes increased. Unit of Aquatic Pathobiology, University of Stirling, Scotland, U.K. (mjj)

Microbiol., 25(6): 752-759. Seawater treated with NaHCO3 and Nag3Oa to remove excess Ca 2+ and Mg ~+, and supplemented with K2HPO4, FeSO4 and crystalline or polymerized urea constitutes an economical culture medium as good as the best synthetic medium for the industrial cultivation of S. maxima as a protein source for humans and animals.

French, German and English papers (64 in total) consider various biogeochemical aspects of the marine milieu. Special emphasis is given to soft-bottom benthic community composition, biomass, distribution and ecology. Biota covered include foraminiferans, fungi, bacteria, polychaetes, fouling organisms, algae, protozoans, nematodes, turbellarians, fish and crustaceans. Suez Canal migrations, estuaries as transition zones and the 'phenomena of surfaces' are also discussed. (izs)
