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 ...

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 ...

Effect of salinity on survival of Metapenaeus anchistus juveniles and subadults
Lebata, Ma. Junemie Hazel L. ; Primavera, Jurgenne (University of the Philippines in the Visayas, 1997)
; Primavera, Jurgenne (University of the Philippines in the Visayas, 1997)
Survival of Metapenaeus anchistus (De Man) juveniles and subadults at 5, 15, 25, 35 (control) and 45 ppt salinity levels was determined and compared. Salinity levels lower than 35 ppt level were prepared by diluting pure ...
