Observations on artificial fertilization of eggs and embryonic and larval development of milkfish, Chanos chanos (Forskal)
; ; Primavera, Jurgenne 
; ; (Elsevier, 1978)
; ; (Elsevier, 1978)
Hydrated eggs obtained from a female milkfish, Chanos chanos, were artificially fertilized with the milt collected from a male injected with acetone-dried pituitaries of salmon. The fertilized eggs (1.1–1.25 mm in diameter) ...

The loss of species: Mangrove extinction risk and geographic areas of global concern
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; Primavera, Jurgenne ; ; ; ; ; (PLoS ONE, 2010)
; ; ; ; ; (PLoS ONE, 2010)
Mangrove species are uniquely adapted to tropical and subtropical coasts, and although relatively low in number of species, mangrove forests provide at least US $1.6 billion each year in ecosystem services and support ...

; ; Primavera, Jurgenne ; Quinitio, Emilia T. ; ; ; ; ; ; ; (Taylor & Francis, 2008)
Over the last decade, hatchery production of mud crabs has become technically and economically more feasible, enabling evaluation of the potential effectiveness of hatchery release in fisheries enhancement. The high growth ...

A comparison of two prawn (Penaeus monodon ) brood stock systems—land–based tanks and marine pens
Primavera, Jurgenne ; (World Aquaculture Society, 1981)
; (World Aquaculture Society, 1981)
The paper compares two prawn (Penaeus monodon) brood stock systems—land-based tanks and marine offshore pens. Construction costs and annual maintenance and operating costs total US\$1,430 and \$2,550 for the tank and \$1,500 ...

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 ...

Are mangroves worth replanting? The direct economic benefits of a community-based reforestation project
; ; Primavera, Jurgenne ; ; (Cambridge University Press, 2006)
; ; (Cambridge University Press, 2006)
Competition for coastal land use and overexploitation have reduced or degraded mangrove coverage throughout much of their distribution, especially in South-east Asia. Timber production was the initial motivation for early ...

Seasonal abundance, distribution and recruitment of mud crabs (Scylla spp.) in replanted mangroves
; ; Lebata, Junemie H. ; ; Primavera, Jurgenne (Elsevier, 2006)
; ; Primavera, Jurgenne (Elsevier, 2006)
The abundance and distribution of mud crabs were studied in a replanted mangrove forest in Buswang, Aklan, Philippines. Two fishing gears, lift nets and bamboo traps, were used to monitor relative abundance of Scylla spp. ...

Development and conservation of Philippine mangroves: institutional issues
Primavera, Jurgenne (Elsevier, 2000)
(Elsevier, 2000)
The decline of Philippine mangroves from half a million hectares in 1918 to only 120 000 ha in 1994 may be traced to local exploitation for fuelwood and conversion to agriculture, salt beds, industry and settlements. But ...
