; ; ; Primavera, Jurgenne ;
; ; ; Primavera, Jurgenne ;
<ol><li>Small-scale fisheries are an important element of the ecosystem goods and services that mangrove habitats provide, especially to poorer coastal communities that rely most on natural resources, and have similar ...
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 ...
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, fishponds, and the quest for sustainability
Primavera, Jurgenne (American Association for the Advancement of Science, 2005)
(American Association for the Advancement of Science, 2005)
Aquaculture, the farming of shrimp and other useful aquatic and marine plants and animals in artificially confined and tended ponds, pens, and cages, ranks as a phenomenal success story in global food production. In 1975, ...
Socio-economic impacts of shrimp culture
Primavera, Jurgenne (Blackwell Publishing, 1997)
(Blackwell Publishing, 1997)
Farmed shrimp contributed 27% of total world shrimp production in 1995 with a volume of 712 000 tonnes. Undoubtedly, the shrimp culture industry earns valuable foreign exchange for developing countries and generates jobs ...

; ; (Springer, 2010)
Practical mapping methods employing GPS field surveys and manual image analyses with affordable software were used to assess two mangrove sites in Aklan Province, NE Panay Island, central Philippines. The Jawili mangroves, ...
Distribution pattern of shrimps and fish among Avicennia and Rhizophora microhabitats in the Pagbilao mangroves, Philippines
; ; ; Primavera, Jurgenne (Elsevier, 1999)
(Elsevier, 1999)
For sustainable management of mangrove ecosystems, there is a pressing need to increase our knowledge of fish and invertebrates associated with this system. This study sampled microhabitats (89–258 m<sup>2</sup>) ...
Gill structure, anatomy and habitat of Anodontia edentula: Evidence of endosymbiosis
Lebata, Ma. Junemie Hazel L. ; Primavera, Jurgenne (National Shellfisheries Association, 2001)
; Primavera, Jurgenne (National Shellfisheries Association, 2001)
Surveys and interviews were conducted to determine sources and habitat of Anodontia edentula. Results showed that they inhabit muddy substrate of mangrove areas or the adjacent mudflats, burying at 20-60 cm deep in the ...
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 ...
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 ...
