On the life-history and ecology of
Hornellia marina gen. et sp. nov.,
(chloromonadineae), causing green
discoloration of the sea and
mortality among marine organisms
off the Malabar coast
There are many published accounts dealing with " red ", " yellow " and
" pink " discoloration of the sea water, caused by the occurrence in swarms
of micro-organisms, particularly members of the Dinophyceae (cf. Hayes
and Austin, 1951). Some of these organisms are known to affect the fishery
adversely. Green discoloration of the sea, however, has not been recorded
frequently. Swarms of Noctiluca harbouring a green flagellate have been
recorded as having rendered the sea green by Weber and Weber van-Bosse
(1890), Delsman (1939-40), Prasad (1953) and recently by Subrahmanyan
(1953)
