From triphenyltins to integrated management of the 'pest' snail Cerithidea cingulata in mangrove-derived milkfish ponds in the Philippines
(Kluwer Academic Publishers, 2000)The potamidid snail Cerithidea cingulata is considered a pest in brackishwater milkfish ponds in the Philippines and has been controlled by the triphenyltin (TPT) compounds Aquatin and Brestan. But TPT is also toxic to ... -
Lipids and fatty acids in wild and pond-reared mud crab Scylla serrata (Forsskål) during ovarian maturation and spawning
(Wiley-Blackwell, 2007)Wild-caught and pond-reared female mud crab Scylla serrata at different stages of ovarian maturation were collected from Samar and Capiz, Philippines. Crabs were categorized into five stages according to the external ... -
The sulfide tolerance of milkfish and tilapia in relation to fish kills in farms and natural waters in the Philippines
(Kluwer Academic Publisher, 1998)Fish kills of milkfish Chanos chanos and tilapia Oreochromis spp. now occur frequently in brackish, marine, and freshwater farms (ponds, pens, and cages) in the Philippines. Aquafarms with high organic load, limited water ... -
Knowledge, gender, and resources in small-scale fishing: The case of Honda Bay, Palawan, Philippines
(Springer Verlag, 2003)The coastal zone is a place of intense activity where resources, users, and resource-use practices interact. This case study of small-scale fisheries in Honda Bay, Palawan, Philippines shows that resources, space, and ... -
Environmental capacity of receiving water as basis for regulating intensity of milkfish (Chanos chanos Forsskal) culture
(Blackwell Publishing, 2004)This paper presents the results of the assessment of the environmental condition of a receiving water and demonstrates how the environmental capacity of the system can be estimated based on effluent discharge from milkfish ... -
Seasonal abundance, distribution and recruitment of mud crabs (Scylla spp.) in replanted mangroves
(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. ... -
A farmer-oriented Nile tilapia, Oreochromis niloticus L., breed improvement in the Philippines
(Blackwell Publishing, 2005)Opportunities for developing small-scale tilapia industry in the Philippines is hampered by the shortage of good-quality seeds and broodstock. Most small-scale farmers are dependent on distribution centres for improved ... -
Oxygen, sulphide and nutrient uptake of the mangrove mud clam Anodontia edentula (Family: Lucinidae)
(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 ... -
Effect of Epinephelus coioides, Chanos chanos, and GIFT tilapia in polyculture with Penaeus monodon on the growth of the luminous bacteria Vibrio harveyi
(Elsevier, 2006)Studies have shown that the presence of Tilapia hornorum hybrid has antibacterial effect against luminous bacteria. The present study aims to determine the effect of different fish species such as grouper, milkfish and ... -
Molecular typing of Vibrio parahaemolyticus strains isolated from the Philippines by PCR-based methods
(Wiley-Blackwell, 2005)Aim: The main aim of the present study was to use three PCR-based techniques for the analysis of genetic variability among Vibrio parahaemolyticus strains isolated from the Philippines. Methods and Results: Seventeen ... -
Microcystins in natural blooms and laboratory cultured Microcystis aeruginosa from Laguna de Bay, Philippines.
(Urban & Fischer Verlag, 2002)Laguna de Bay, the largest freshwater lake in the Philippines, experiences periodic blooms of the cyanobacteria Microcystis aeruginosa. Blooms of these cyanobacteria in 1996, 1998 and 1999 were sampled. HPLC and MALDI-TOF ... -
Temperature fluctuation, low salinity, water microflora: Risk factors for WSSV outbreaks in Penaeus monodon.
(Society of Israeli Aquaculture and Marine Biotechnology, 2011)White spot syndrome virus (WSSV) has been devastating the shrimp industry for almost a decade. This study compares water parameters, alkalinity, and microflora in three ponds on a farm on Negros Island (Philippines) during ... -
Effect of iodine disinfection on the bacterial flora and hatching rate of grouper, Epinephelus coioides eggs at the cleavage and eyed stages
(European Association of Fish Pathologists, 2001)In this study, the effect of iodine disinfection on the bacterial flora and hatching rate of grouper egg at two different stages of development were investigated. The eggs (at cleavage and eyed stages) were soaked for 10 ... -
Protected areas for biodiversity conservation and environment education in the Philippines
(Science and Technology Information Institute, 1999)The Philippines holds the distinction of having enormous biodiversity with the highest density of endemic species but has the problem of very fast decline in old-growth forests and the highest number of endangered mammal ... -
Mud crab pen culture: replacement of fish feed requirement and impacts on mangrove community structure
(Blackwell Publishing, 2010)Brackishwater pond culture has been a major factor in mangrove loss in Southeast Asia, hence, the need to develop environment-friendly technologies such as mud crab Scylla (Portunidae) culture in mangrove pens exists. This ... -
Food selection of early grouper, Epinephelus coioides, larvae reared by the semi-intensive method
(Japan Aquaculture Society, 1997)The grouper, Epinephelus coioides, larvae were reared in outdoor tanks with nauplii of copepods and/or rotifers, Brachionus rotundiformis as food. Nauplii propagated in tanks consisted mainly of Pseudodiaptomus annandalei ... -
LHRHa and pimozide-induced spawning of Asian catfish Clarias macrocephalus (Gunther) at different times during an annual reproductive cycle
(Elsevier, 1997)Captive Clarias macrocephalus were induced to spawn during the off-season (February), before (May), during (August) and end (November) of the natural breeding period to test their seasonal responsiveness to hormone treatment, ... -
Testicular histology and serum steroid hormone profiles in hatchery-bred catfish Clarias macrocephalus (Gunther) during an annual reproductive cycle
(Japanese Society of Fisheries Science, 1997)Testicular development, gonadosomatic index (GSI), and related steroid hormones (testosterone or T, 11-ketotestosterone or 11-KT, 17α, 20β-dihydroxy-4-pregnen-3-one or DHP) in serum were monitored during an annual reproductive ... -
