Lumut is the Tagalog term used to designate the assemblage of fitamentous green algae (Chlorophyceae) sometimes intermingled with filamentous blue-green algae (Myxophyceae) growing in brackish and salt-water ponds and composing the main bulk of the natural food of cultivated bañgos, or milkfish, Chanos chanos (Forskål).
The present experiment is intended to provide the basic rate of production data that may eventually be used as a standard of estimate of productivity in bañgos fishpond projects. It was undertaken at the Dagat- dagatan Salt-Water Fishery Experimental Station, Malabon-Navotas, Rizal, in six equally-sized ponds lying side by side, for a period of eight months and divided into two experimental runs of four months duration.
“Lumut” is a vernacular term (Tagalog) used for the as¬semblage of filamentous green algae (Class Chlorophyceae) and sometimes intermingled with some of the filamentous blue-green algae (Class Myxophyceae) which grow in brackish and salt-water ponds in the Philippines. It composes the main bulk of the food of bañgos, or milkfish, Chanos chanos (Forskål) under cultivation.
The following experiment on lumut is intended to provide a method of estimating the total production of the algae per unit area under conditions obtaining in Philippine milkfish ponds. This should provide a basis in estimating the bañgos productivity in fishpond projects. Experimental work was un¬dertaken from November 1, 1949 to February 27, 1950 and from July 31, 1950 to October 30, 1950 at the Dagat-dagatan Salt-Water Fishery Experimental Station, Malabon-Navotas, Rizal Province, Luzon.
