Acute toxicity of water-accommodated fraction and chemically enhanced WAF of bunker C oil and dispersant to a microalga Tetraselmis tetrathele
(Springer Verlag, 2016)This study assessed the toxicity of water-accommodated fraction (WAF) and chemically enhanced WAF (CEWAF) of bunker C oil and dispersant (DISP) to a microalga, Tetraselmis tetrathele. The 72-h median effective concentration ... -
Improved growth performance of Gracilariopsis heteroclada via short-term nitrogen enrichment
(De Gruyter, 2015)This study examined the effect of short-term nitrogen (N) enrichment on Gracilariopsis heteroclada growth and agar quality. Planting materials were soaked in different concentrations of ammonium chloride (NH4Cl) ... -
Colour preference and colour vision of the larvae of the giant freshwater prawn Macrobrachium rosenbergii
(Elsevier, 2016)This paper reports on the innate colour preference and colour vision in the hatchery-reared larvae (10–16 days old, stages IV–VIII) of the giant freshwater prawn Macrobrachium rosenbergii (De Man) based on their response ... -
Use of immunostimulants in shrimp culture: An update
(Research Signpost, 2015)Different approaches are used to prevent and control diseases in aquaculture. Immunostimulation is one method that is gaining popularity and is considered a promising development in aquaculture. Immunostimulants were found ... -
Low pH affects survival, growth, size distribution, and carapace quality of the postlarvae and early juveniles of the freshwater prawn Macrobrachium rosenbergii de Man
(Springer Verlag, 2015)Acidification of rain water caused by air pollutants is now recognized as a serious threat to aquatic ecosystems. We examined the effects of low pH (control pH 7.5, pH 6, pH 5, pH 4) on the survival, growth, and shell ... -
Dietary soy peptide enhances thermotolerance and survival of juvenile japanese flounder, Paralichthys olivaceus
(World Aquaculture Society, 2015)Soy peptide (SP), a soy protein enzymatic hydrolysate, contains bioactive substances that could be utilized as an immune-stimulating feed ingredient. The experiment evaluated the efficacy of dietary SP on promoting growth, ... -
Total volume of 3D small patch reefs reflected in aerial photographs can predict total species richness of coral reef damselfish assemblages on a shallow back reef
(Springer Verlag, 2015)Because fish have a high dispersal ability, an understanding coral reef fish metacommunity structure is vital for effective conservation. Coral reefs provide patchy habitat of various sizes and scales. We examined the ... -
Physiological and avoidance responses of juvenile mud crab Scylla serrata to mercury
(Bioflux, 2014)The physiological and avoidance responses of juvenile mud crab Scylla serrata to mercury was evaluated by determining mortality using a renewal-type acute toxicity test and assessing crabs’ ability to avoid toxic concentrations. ... -
Evidence of WSSV transmission from the rotifer (Brachionus plicatilis) to the black tiger shrimp (Penaeus monodon) postlarvae and means to control rotifer resting eggs using industrial disinfectants
(Bioflux, 2012)Rotifers are considered possible vectors of the white spot syndrome virus (WSSV) and have been implicated in its recurrence in pond-cultured shrimp. However, direct evidence of the transmission and the pathogenicity of ... -
Seasonal gonad cycle of the climbing perch Anabas testudineus (Teleostei: Anabantidae) in a tropical wetland
(Springer Verlag, 2015)Seasonal reproduction of the climbing perch Anabas testudineus in the Candaba wetland, Philippines, is described. Monthly specimens were collected, gonads and viscera excised, and the gonads histologically examined. Low ... -
Utilization of mung bean, Vigna radiata (Linnaeus) as a novel protein source in practical-type diets for juvenile milkfish, Chanos chanos (Forsskal): Effects on growth, feed efficiency, body composition, and histology of gut and liver
(Society of Israeli Aquaculture and Marine Biotechnology (SIAMB), 2015)A 15-week feeding trial was conducted to determine the optimum partial inclusion of mung bean protein in milkfish diet. Six isonitrogenous practical-type diets with mung bean included at 0%, 4%, 8%, 12%, 16%, and 20% of ... -
Qualitative and quantitative comparison of bacterial flora associated with hatchery-reared and wild-caught shrimp postlarvae
(ASIARESIST, 2005)Because of high mortality recorded in pond-reared shrimps due to luminescent vibriosis infection, a study was conducted to determine if postlarvae (PLs) could be major sources of luminescent bacteria (LB). Batches of ... -
Antimicrobial resistance in bacteria isolated from aquaculture environments in the Philippines
(ASIARESIST, 2005)Antibiotics have been used in aquaculture as feed additives to promote growth and added in water to prevent disease occurrence. Therapeutic doses are used to treat diseases. Long-term use and misuse of antibiotics may ... -
Sustainable milkfish production in marine fish cages through strong government support and effective public-private partnerships: a case study from Panabo City Mariculture Park in Davao del Norte, Philippines
(FAO Regional Office for Asia and the Pacific, 2016)This case study presents the successful practice of sustainable intensification of milkfish aquaculture in marine fish cages under semi-intensive grow-out conditions in the Panabo City Mariculture Park (PCMP) in Davao del ... -
Protein concentrate of Ulva intestinalis (Chlorophyta, Ulvaceae) could replace soybean meal in the diet of Oreochromis niloticus fry
(Bioflux, 2014)An experiment was conducted to evaluate the effects of replacing soybean meal with the protein concentrate of Ulva intestinalis (UPC) in the diet of juvenile Nile tilapia, Oreochromis niloticus. Four experimental diets ... -
Metabolic rate characteristics and sediment cleaning potential of the tropical sea cucumber Holothuria scabra
(Ministry of Tropical Agricultural Research Centre, 2015)The oxygen consumption rate (OCR) and ammonium excretion rate (AER) of a tropical sea cucumber, Holothuria scabra, were determined in laboratory experiments. OCR and AER exhibited a significant negative correlation ... -
The first record of a cupped oyster species Crassostrea dianbaiensis in the waters of Japan
(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 pattern of the tropical sea cucumber, Holothuria scabra, under captivity
(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. ... -
Dietary substitution of protein concentrate of Ulva lactuca for soybean meal in the black tiger shrimp Penaeus monodon fry
