Light color and ovarian maturation in unablated and ablated giant tiger prawn Penaeus monodon (Fabricius)
Primavera, Jurgenne ; (Elsevier, 1992)
; (Elsevier, 1992)
The effect of light color (green, blue and white fluorescent lights, with natural light as a control) on maturation in intact and eyestalk-ablated Penaeus monodon was tested in 12-m<sup>3</sup> broodstock tanks. Size and ...

A review of mangrove rehabilitation in the Philippines: successes, failures and future prospects
Primavera, Jurgenne ; (Springer, 2008)
; (Springer, 2008)
From half a million hectares at the turn of the century, Philippine mangroves have declined to only 120,000 ha while fish/shrimp culture ponds have increased to 232,000 ha. Mangrove replanting programs have thus been ...

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 ...
