Environmental control of annual reproductive cycle and spawning rhythmicity of spinefoots
(Graduate School of Kuroshio Science, Kochi University, 2015)Many teleost fishes inhabiting shallow tropical waters exhibit synchronous spawning around species-selective lunar phases during their spawning season. For example, ovaries of the goldlined spinefoot (Siganus guttatus) ... -
Parasites of window-pane oyster (Placuna placenta Linnaeus, 1758) from Trapiche, Oton in west central Philippines
(College of Agriculture, University of the Philippines Los Baños, 2015)Parasitology of edible and commercially valuable window-pane oysters (Placuna placenta L.) using gross macroscopic examination and histology was conducted. To screen for the presence of parasites, wild oysters were collected ... -
Impacts of aquaculture on fish biodiversity in the freshwater lake Laguna de Bay, Philippines
(Wiley, 2016)Laguna de Bay is the largest inland water body in the Philippines, being used predominantly for aquaculture and open water fisheries. Aquaculture in the lake began decades ago, with many changes in the lake ecosystem having ... -
Do adaptation and coping mechanisms to extreme climate events differ by gender? The case of flood-affected households in Dumangas, Iloilo, Philippines
(Asian Fisheries Society, 2014)This study was conducted to identify and analyse gender-differentiated adaptation measures and coping mechanisms formulated and implemented by households during Typhoon Frank (international name Fengshen), in barangays ... -
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 ... -
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 ... -
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 ... -
