BIOLOGY O F SEAWEEDS OF ECONOMIC IMPORTANCE

need for conservation and a “ farming ” of the available stocks.
The aim of the present work will be to summarize recent advances in
our knowledge of the general biology of the seaweeds of economic
importance, and in particular to explore those aspects which are
germane to their availability and productivity as crop plants. This will
include knowledge of their systematics, life histories, sporing seasons,
conditions of growth and effects on the products, and on harvesting
times and techniques and subsequent effects on the standing crops.
For this purpose the studies carried out within the last two decades
have been mainly drawn on as sources of information. It is of interest
to note that whilst earlier work stressed the fact that the full potentialities of the seaweed industry were yet to be developed (Chapman,
1950), in later reviews there is clear demonstration of the great expansion in the various aspects of the utilization of marine algae (Newton,
1963).
11. THE SEAWEEDS OF ECONOMIC IMPORTANCE
The list of marine algae which follows is not an exhaustive compilation of all seaweeds utilized by man, but will show the main species
described in the following pages, together with the authorities for the
nomenclature. In subsequent pages only the generic and species names
will be given without the authorities. Many of the plants of more
restricted use which are confined to certain localities have not been
included, since these have been described in a detailed fashion elsewhere, e.g. Zaneveld’s (1959) account of the marine algae of south and
east Asia. The synonyms of some of the species are given in parenthesis, and the numerical code after each plant indicates the way in which
it is utilized, viz., (1) = human food; (2) = animal fodder; (3) = soil
dressing; (4) = extractives (organic or inorganic). The many subsidiary uses, medicinal and otherwise, are not included.
