Growth pattern of the tropical sea cucumber, Holothuria scabra, under captivity
; ; Lebata-Ramos, Ma. Junemie Hazel 
(Ministry of Tropical Agricultural Research Centre, 2014)
(Ministry of Tropical Agricultural Research Centre, 2014)
The growth of the juvenile sea cucumber, Holothuria scabra, was studied under captivity to elucidate the growth variation pattern and determine the best-fit growth model to estimate age- and size-specific growth rates. ...

The first record of a cupped oyster species Crassostrea dianbaiensis in the waters of Japan
; ; ; ; Lebata-Ramos, Ma. Junemie Hazel ; (Springer Verlag, 2015)
; (Springer Verlag, 2015)
With a combination of our mitochondrial and nuclear DNA data, we evidenced the occurrence of a Crassostrea oyster hitherto unrecognized in Japan. This species, C. dianbaiensis (named Sumizome-gaki in Japanese), was very ...

Growth and survival of hatchery-bred giant clams (Tridacna gigas) in an ocean nursery in Sagay Marine Reserve, Philippines
Lebata-Ramos, M. Junemie Hazel L. ; ; ; ; ; ; (European Aquaculture Society, 2010)
; ; ; ; ; ; (European Aquaculture Society, 2010)
To restore the diminishing population of the giant clam Tridacna gigas in Sagay Marine Reserve (SMR), Negros Occidental, central Philippines, two size classes [8- and 10-cm shell length (SL)] of hatchery-bred T. gigas were ...

Oxygen, sulphide and nutrient uptake of the mangrove mud clam Anodontia edentula (Family: Lucinidae)
Lebata, Ma. Junemie Hazel L. (Elsevier, 2001)
(Elsevier, 2001)
Oxygen, sulphide and nutrient (ammonia, nitrite and phosphate) uptake of Anodontia edentula was measured. Oxygen and sulphide were measured from sealed containers provided with 1 l fresh mangrove mud (sulphide source) and ...

Approaches to stock enhancement in mangrove-associated crab fisheries
; Lebata, Ma. Junemie Hazel L. ; ; Primavera, Jurgenne ; Quinitio, Emilia T. ; ; ; ; ; ; ; (Taylor & Francis, 2008)
; ; 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 ...

Metabolic rate characteristics and sediment cleaning potential of the tropical sea cucumber Holothuria scabra
; ; Lebata-Ramos, Ma. Junemie Hazel ; (Ministry of Tropical Agricultural Research Centre, 2015)
; (Ministry of Tropical Agricultural Research Centre, 2015)
The oxygen consumption rate (OCR) and ammonium excretion rate (AER) of a tropical sea cucumber, <i>Holothuria scabra</i>, were determined in laboratory experiments. OCR and AER exhibited a significant negative correlation ...

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. ...

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 ...

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 ...

Size measurement and nutritional condition evaluation methods in sandfish (Holothuria scabra Jaeger)
; ; ; Lebata-Ramos, Maria Junemie Hazel ; (Wiley, 2012)
; (Wiley, 2012)
The aims of this study were to establish an accurate size measurement method and a nutritional condition evaluation method of Holothuria scabra (Jaeger). Although 0.5% KCl and 0.05% MgSO<sub>4</sub> did not induce anaesthesia, ...
