Effects of crude, semipurified, and purified starch of sago (Metroxylon sagu Rottb.) on the water stability of pelleted shrimp diets
(Fisheries Research Society of the Philippines, 1979)Three isonitrogenous, isocaloric practical-type diets with purified, semipurified and crude starch from sago palm as binders, were pelleted through a 2-mm diameter die in a Hobart meat grinder, steamed for 5 min at 85 to ... -
Results of drift card experiments and considerations on the movement of milkfish eggs and larvae in the northern Sulu Sea
(Fisheries Research Society of the Philippines, 1979)For a period of one year beginning December 1977, drift card experiments were conducted off the western and southwestern coasts of Panay Island to determine the surface currents in the area. Of a total 2,384 drift cards ... -
