(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 ... -
The genetic improvement of farmed tilapias project: Impact and lessons learned
(Springer, 2010)In response to challenges that the developing world confront on food security and malnutrition, the last two decades have witnessed increased efforts in genetic improvement to enhance production traits of commercially ... -
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 ... -
Ovarian development and serum steroid hormone profiles in hatchery-bred female catfish Clarias macrocephalus (Gunther) during an annual reproductive cycle
(Japanese Society of Fisheries Science, 1997)Ovarian development e.g. gonadosomatic index, oocyte diameter, fecundity, histology, and related steroid hormones e.g. testosterone (T), estradiol-17 β (E2), 17α, 20 β-dihydroxy-4-pregnen-3-one (DHP), were ... -
World wide aquaculture drug and vaccine registration progress
(European Association of Fish Pathologists, 1997)Harmonisation of the most important standards and guidelines required in each country. A start has been shown to be made in developing an international effort toward aquaculture drug approvals and vaccine licensure and ... -
Growth and reproductive performance of the Asian catfish Clarias macrocephalus (Gunther) fed artificial diets
(Blackwell Publishing, 1997)Four natural ingredient diets similar in nutrient composition (crude protein = 42–44%; P/E ratio = 115–120 mg/kcal) but different in protein sources, were formulated and fed to hatchery-reared catfish to measure the relative ... -
Semi-mass culture of the dinoflagellate Gymnodinium splendens as a live food source for the initial feeding of marine finfish larvae
(Springer Verlag, 1997)A technique was developed for the semi-mass culture of the unarmored dinoflagellate, Gymnodinium splendens under laboratory conditions. A maximum cell density of 4600 to 6800 cells ml−1 was observed within 8 to ... -
Laboratory manipulation of Gracilariopsis bailinae Zhang et Xia (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1997)Carpospore germination, carposporeling development and tetraspore formation were investigated in Gracilariopsis bailinae Zhang et Xia by manipulating photoperiod, photon flux density, temperature, salinity and nutrients. ... -
Mariculture development and livelihood diversification in the Philippines
(Elsevier, 2012)This paper aims to evaluate mariculture as sustainable livelihood diversification option for coastal fishers in the Philippines and guide policy development in this direction. Mariculture in the Philippines refers to the ... -
Induction of sex change in female Epinephelus coioides by social control
(Society of Israeli Aquaculture and Marine Biotechnology, 1997)Mature female groupers (Epinephelus coioides) of different sizes were stocked in three floating net cages (2 fishes each) and in tanks (2-4 fishes) to induce sex change in the bigger female grouper after isolation from the ... -
Socio-economic impacts of shrimp culture
(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 ... -
Fish predation on mangrove-associated penaeids: The role of structures and substrate
