On predicting the setting season of the oyster Crassostrea iredalei in Himamaylan River, Negros Occidental
(University of the Philippines at Los Baños, 1983)
A spatfall forecasting program in April-November 1981 suggests that daily counts of larvae in plankton samples may be used to forecast spatfall of C. iredalei . Counts of at least five ready-to-settle larvae per 100-liter ...
The food and feeding habit of Penaeus monodon Fabricius collected from Makato River, Aklan, Philippines (Decapoda: Natantia)
(E.J. Brill, 1980)
The food of Penaeus monodon Fabricius collected from Makato River, Aklan, consisted mainly of Crustacea (small crabs and shrimps) and molluscs, making up 85% of ingested food. The remaining 15% consisted of fish, polychaetes, ...
