Mangroves and brackishwater pond culture in the Philippines
Primavera, Jurgenne (Springer Verlag, 1995)
(Springer Verlag, 1995)
Around 50% of mangrove loss in the Philippines can be traced to brackishwater pond construction. The decrease in mangroves from 450 000 ha in 1920 to 132 500 ha in 1990 has been accompanied by expansion of culture ponds ...

Preliminary results of feeding aquatic macrophytes to Penaeus monodon juveniles
Primavera, Jurgenne ; (Elsevier, 1989)
; (Elsevier, 1989)
Penaeus monodon juveniles (PL<sub>50</sub>) were fed live and decaying aquatic macrophytes and a commercial grow-out pellet (40% crude protein) in 80-l glass tanks over a 30-day period. Growth and survival were significantly ...
