resources me available in the work of Tseng and Chang (1959) for the
economic marine algae of the Yellow Sea and the East China Sea, and
Varma and Rao (1964) have reported on the algal resources of Pambam.
The standing crops of harvestable Aswphyllum nodosum on the shores
of Southern Iceland have been described by Munda (1964), together
with some account of their chemical composition. Diaz-Piferer and
de Perez (1964) have given an account of the agar producing and
agaroid algm of Puerto Rico. The extractive content of forty-four
species is described, together with more detailed accounts of the biology
of nineteen plants, including Hypnea musciformis and thirteen species
of &milaria. Accorinti (1963) has given additional information on the
seaweeds of economic importance in Argentina.
Further information is also available on aspects of the biology of
certain of the marine algae described in the review. Thus Kain (1966)
has reported on the results of a study of the effects of light and temperature on the early growth of the sporophyte of Laminaria hyperborea. Mitrakos (1964) has given an account of the effects of various
environmental factors (pH of the medium and light) on the growth of
the young cqosporophytes of Bracilaria verrucosa. Further studies
on the productivity of the Japanese agarophyte Belidium amalzsii have
recently been reported. Thus Yamada (1964) hcts described the uptake
of phosphorus and nitrogen and Yamada et al. (1964) have reported on
the rates of absorption of P3a compounds. The use of mineral salts as
fertilizers for underwater beds of the agarophyte has been studied
(Yamada and Iwahmhi, 1964). A marked improvement wm observed
in both the colour and condition of " yellowed " Belidium fronds after
bags of fertilizer had been placed in the near vicinity of underwater
beds of the agarophyte.
