Evaluation of hatchery-based enhancement of the mud crab, Scylla spp., fisheries in mangroves: comparison of species and release strategies
Lebata, Ma. Junemie Hazel L.
; ; ; ; Quinitio, Emilia T. ; ; Primavera, Jurgenne (CSIRO Publishing, 2009)
Ranching, stock enhancement and restocking are management approaches involving the release of wild or hatchery-bred organisms to enhance, conserve or restore fisheries. The present study, conducted from April 2002 to ... -
Molecular epidemiology of koi herpesvirus
(Japanese Society of Fish Pathology, 2009)Three regions of koi herpesvirus (KHV) genomic DNA were compared for 34 samples from Japan, six from Indonesia, two from Taiwan, one from the Philippines, 13 from the Netherlands, one from the UK, one from the USA and one ... -
Non-linearity in ecosystem services: temporal and spatial variability in coastal protection
; ; ; ; ; ; ; Primavera, Jurgenne; ; ; ; ; ; (Ecological Society of America, 2009)
Natural processes tend to vary over time and space, as well as between species. The ecosystem services these natural processes provide are therefore also highly variable. It is often assumed that ecosystem services are ... -
Use of Acadian marine plant extract powder from Ascophyllum nodosum in tissue culture of Kappaphycus varieties
(Springer Verlag, 2009)Three varieties of Kappaphycus alvarezii (Kapilaran, KAP), Tambalang purple (PUR), Adik-adik (AA), and one variety of Kappaphycus striatum var. sacol (green sacol (GS) were used to determine the efficiency of Acadian marine ... -
Price dynamics and cointegration in the major markets of aquaculture species in the Philippines
(Southeast Asian Regional Center for Graduate Study and Research in Agriculture, 2009)This study explored the interdependencies of aquaculture markets in the Philippines by establishing price cointegration between wholesale and retail prices of three major species commonly farmed in the country, i.e., ... -
Grow-out of juvenile seahorse Hippocampus kuda (Bleeker; Teleostei: Syngnathidae) in illuminated sea cages
Garcia, Luis Maria; (Blackwell Publishing, 2009)
This paper examines the feasibility of rearing 10–15-day- and 0.7–1.5-month-old seahorse Hippocampus kuda in illuminated sea cages to continue existing hatchery protocols to mass produce H. kuda for trade and enhance ... -
Enrichment potential of HUFA-rich thraustochytrid Schizochytrium mangrovei for the rotifer Brachionus plicatilis
(Elsevier, 2009)An enrichment experiment was performed to evaluate the changes in lipid and essential fatty acid contents of the rotifer Brachionus plicatilis fed with freeze-dried cells of tropical thraustochytrid Schizochytrium mangrovei ... -
Cage culture of the Pacific white shrimp Litopenaeus vannamei (Boone, 1931) at different stocking densities in a shallow eutrophic lake
(Blackwell Publishing, 2009)Postlarvae of Litopenaeus vannamei were acclimated and stocked in lake-based cages at the following stocking densities: 10, 20, 30 and 40 shrimp m−2. Another set of shrimp was stocked in concrete tanks as reference ... -
Microsatellite and mitochondrial haplotype diversity reveals population differentiation in the tiger shrimp (Penaeus monodon) in the Indo-Pacific region
(International Society for Animal Genetics, 2008)The black tiger shrimp (Penaeus monodon) is an ecologically and economically important penaeid species and is widely distributed in the Indo-Pacific region. Here we investigated the genetic diversity of P. monodon (n = ... -
Distribution and symptoms of epiphyte infection in major carrageenophyte-producing farms
(Springer Verlag, 2008)High density commercial farming of carrageenophyte Kappaphycus alvarezii is often plagued with “ice-ice” disease and epiphyte infection, which eventually leads to reduced production and in some cases collapse of crop. ... -
Indicators of diminished organic matter degradation potential of polychaete burrows in Philippine mariculture areas
(University of the Philippines Los Baños, 2008)Sediments from underneath fish cages and in mesocosm tanks were examined to establish indicators of diminished organic matter degradation potential of polychaete burrows from increased mariculture activities in Bolinao-Anda, ... -
Low isozyme variation in native and transplanted populations of the endemic Philippine silver perch, Leiopotherapon plumbeus (Kner, 1864) from three lakes in the Philippines
(College of Agriculture, University of the Philippines Los Baños, 2008)The silver perch, Leiopotherapon plumbeus (Kner, 1864), is an endemic and economically important fish in the Philippines. A native species of Laguna de Bay, the silver perch was transplanted from this lake to Sampaloc Lake ... -
Enhancing nonspecific immune response of grouper, Epinephelus coioides using levamizole as immunostimulant
; ; Amar, Edgar (University of the Philippines in the Visayas, 2008)
The use of levamisole as an alternative approach to disease prevention and control has been resorted to in aquaculture. Its immunomodulatory effect in several fish species is well documented but its effect on grouper, ... -
Diurnal feeding pattern and gut content of milkfish Chanos chanos (Forsskål, 1775) cultured semi-intensively during the wet and dry season in brackish ponds in the Philippines
(Blackwell Publishing, 2008)To improve feeding management and reduce feed cost in semi-intensive grow-out culture of milkfish (Chanos chanos, Forsskål 1775) in brackish ponds, the relative shares of natural food (NF) and supplemental feed (SF) ingested ... -
Purification and properties of a non-stereospecific dehalogenase enzyme E (DehE) from Methylobacterium sp. HJ1
; ; ; Pakingking, Rolando V., Jr.; ; (Academic Journals, 2008)
The bacterial isolate HJ1, which was identified as a Methylobacterium sp., grew on 2, 2-dichloropropionic acid as the sole carbon source and produced a 2-haloalkanoic acid hydrolytic dehalogenase. This non-stereospecific ... -
Biodegradation of monochloroacetic acid by a presumptive Pseudomonas sp. strain R1 bacterium isolated from Malaysian paddy (rice) field
; ; ; ; ; Pakingking, Rolando V., Jr.; (Asian Network for Scientific Information, 2008)
A bacterial strain tentatively identified as Pseudomonas sp. R1 was isolated from a paddy (rice) field that could degrade monochloroacetic acid (MCA) for concentrations ranging from 5 to 40 mM. Quantitative agreement between ... -
Growth and carrageenan quality of Kappaphycus striatum var. sacol grown at different stocking densities, duration of culture and depth
(Springer Verlag, 2008)Kappaphycus striatum var. sacol was grown in two separate studies: (1) at two stocking densities, and (2) at four different depths, each for three different durations of culture (30, 45 and 60 days) in order to determine ... -
Intertidal burrows of the air-breathing eel goby, Odontamblyopus lacepedii (Gobiidae: Amblyopinae)
(Ichthyological Society of Japan, 2008)Odontamblyopus lacepedii inhabits burrows in mudflats and breathes air at the surface opening. Investigations of the intertidal burrows using resin casting demonstrated a highly branched burrow system. The burrows are ... -
Respiratory vasculatures of the intertidal air-breathing eel goby, Odontamblyopus lacepedii (Gobiidae: Amblyopinae)
(Springer Verlag, 2008)Lacking a propensity to emerge over the mud surface, the eel goby, Odontamblyopus lacepedii, survives low tide periods by continuously breathing air in burrows filled with hypoxic water. As with most marine air-breathing ... -
