Title Boring sponges destructive to economically important
Molluscan beds and coral reefs in Indian seas
 
Creator Thomas, P A
 
Subject Sponges
Coral Reefs
 
Description Systematics, descr'ption and distribution are given of 32 species of boring
sponges from the Indian seas, the frequency of occurrence of which can vary
from time to time as any one or more speci'js can at any lime cause
an outburst creating severe havoc in the economically important molluscan and
coral bedis and then disappear into a period of quiescent stage, while some others
may continue to exhibit moderate incidence without causing any such deleterious
effects.
During the period of the present study only some species were moderately
active an the Indian seas, and those, in the order of abundance, were Cliona celata,
C. vastifica and C. carpenteri on chanks; C. vastifica and C. celata on pearl oysters;
C. celata, C. vastifica and C. carpenteri on edible oysters; C. celata, Spirastrella
cuspidifera, S. inconstans and S. aurivilli on corals. The present composition of
boring sponge in the Indian seas is liliely to get altered in future, and such
changes if any may be well affirmed by comparing with the observations presently
reported.
The boring pattern, damage caused to the shell, the modes of reproduction
of the sponges, etc., are discussed. Some of the common measures adopted for
controlling the boring sponges in different parts of the world are reviewed.
Illustrations are provided for all the 32 species described.
