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
Santander-Avancena, Sheryll; Luhan, Maria Rovilla ; (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
; Bagarinao, Teodora; ; ; (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 ... -
Low pH affects survival, growth, size distribution, and carapace quality of the postlarvae and early juveniles of the freshwater prawn Macrobrachium rosenbergii de Man
; Bagarinao, Teodora; ; ; ; (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
; Mamauag, Roger Edward; ; ; (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
; ; ; Quinitio, Emilia T. (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
; Faisan, Joseph P., Jr.; ; ; ; (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 ... -

; Aya, Frolan; ; Garcia, Luis Maria (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 ... -
Protein concentrate of Ulva intestinalis (Chlorophyta, Ulvaceae) could replace soybean meal in the diet of Oreochromis niloticus fry
