Although many fisheries stocks have declined precipitously throughout the world, fish farming--and especially shrimp and salmon farming--has boomed. The increasingly large scale of these enterprises is now having unforeseen ...
Intensive prawn farming in the Philippines: ecological, social, and economic implications
Primavera, Jurgenne (Springer Verlag, 1991)
(Springer Verlag, 1991)
The benefits of intensive farming of the giant tiger prawn Penaeus monodon in the Philippines are discussed in relation to the environmental costs. Ecological effects include mangrove conversion into ponds; use of antibiotics ...
A survey of chemical and biological products used in intensive prawn farms in the Philippines
Primavera, Jurgenne ; ; ; (Elsevier, 1993)
; ; ; (Elsevier, 1993)
With attractive prawn export prices and the availability of hatchery fry and commercial feeds, Philippine aquaculture has experienced a shift from milkfish to prawn Penaeus monodon and an intensification from traditional ...
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 ...

Stable carbon and nitrogen isotope ratios of penaeid juveniles and primary producers in a riverine mangrove in Guimaras, Philippines
Primavera, Jurgenne (University of Miami, Rosenstiel School of Marine and Atmospheric Science, 1996)
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 1996)
Stable carbon and nitrogen isotope ratios were analyzed for primary producers and juveniles of four penaeid species (Metapenaeus ensis, Penaeus indicus, P. merquiensi and P. monodon) in a riverine mangrove in Guimaras, ...
Mangroves and brackishwater pond culture in the Philippines
Primavera, Jurgenne (Springer Verlag, 1995)
