Biofloc-based nursery production system: Heeding the call towards a sustainable shrimp culture industry in the Philippines
(International Network for Natural Sciences, 2022)
The increasing global population resulted in intense pressure on the food production sectors to meet the rise in food demand. The aquaculture industry, which is one of the major food production sectors, provides opportunities ...
Effect of background tank color in combination with sand substrate and shelters on survival and growth of Scylla tranquebarica instar
(Elsevier, 2022-05)
Effect of tank color in combination with substrate-shelters on the survival and growth of the instar of purple mud crab, Scylla tranquebarica (initial body weight of 28.7 ± 2 mg) was investigated. Ten treatments were tested ...
Phylogenetic analysis of tilapia lake virus (TiLV) isolates from the Philippines based on partial genome segment 3 sequences
(College of Agriculture and Food Science, University of the Philippines Los Baños, 2022-03)
This study aimed to expand current knowledge on TiLV genetic diversity by sequence analysis of a portion of genome segment 3 of TiLV detected from the Philippines. This includes a recently deposited sequence in GenBank ...
Vibrio load and percentage composition of sucrose‐fermenting vibrios in Nile tilapia (Oreochromis niloticus) cultured in brackish water earthen ponds and biocontrol potential of recycled tilapia‐conditioned greenwater against population growth of V. parahaemolyticus and non‐sucrose‐fermenting vibrios in the grow‐out culture of white leg shrimp (Litopenaeus vannamei)
(Wiley, 2022-10-20)
<i>Vibrio</i> are known opportunistic pathogens of pond-cultured fish and shrimp. This study determined the presumptive <i>Vibrio</i> count (PVC) and percentage composition of “beneficial” sucrose-fermenting vibrios (SFVs) ...
Evaluation of seafloor environmental characteristics of harvesting ground of a kelp Saccharina longissima using GIS in the Pacific coastal area of eastern Hokkaido, Japan
(Elsevier, 2022-09)
The characteristics of the seafloor environment of the harvesting grounds of the kelp, Saccharina longissima, were evaluated by spatial analysis using a geographic information system (GIS) in the Pacific coastal area of ...
Daytime habitat use and abundance of a freshwater shrimp Macrobrachium yui Holthuis, 1950 (Decapoda: Palaemonidae) in tropical forest stream, northern Laos
(Carcinological Society of Japan, 2021-11-30)
From 2008 to 2014, we monitored the abundance and daytime habitat use of the freshwater shrimp <i>Macrobrachium yui</i> at a fixed site on a tributary of the Xuang River in northern Laos. Throughout the monitoring period, ...
Acute lethal toxicity of dried garlic (Allium sativum) powder on orange-spotted grouper (Epinephelus coioides) juveniles under static exposure
(European Association of Fish Pathologists, 2022-10-05)
The present study was carried out to assess the toxic effect and determine the lethal concentration of dried garlic (Allium sativum) powder on the orange-spotted grouper (Epinephelus coioides) juveniles. Laboratory static bioassays were conducted to determine the 96-h LC<sub>50</sub> of different concentrations of garlic (0, 30, 60, 90, 120, 150 and 180 mg L<sup>-1</sup>) on grouper juveniles (mean weight, 35.4±6.18 g and mean length, 13.2±0.51 cm). The 96-h LC<sub>50</sub> was 74.78 mg L<sup>-1</sup> with lower and upper confidence limits of 62.8 and 89.06 mg L<sup>-1</sup>, respectively. All fish exposed to 30 to 180 mg L<sup>-1</sup> exhibited rapid movement, faster opercular activity and erratic swimming whereas at higher concentrations (90 mg L<sup>-1</sup> to 180 mg L<sup>-1</sup>) fish showed additional behavioral changes such as loss of balance, lethargy, gulping for air and respiratory distress. Water quality parameters were within the recommended acceptable limits. This LC<sub>50</sub> value can be used as a baseline reference to generate an effective concentration of garlic for future prophylaxis and treatment for parasitic, viral and bacterial infection in grouper....
Developing a self-sufficient Philippine milkfish industry through value chain analysis
(Elsevier, 2021-02-15)
The Philippine milkfish industry has been dependent on the importation of juveniles for grow-out ever since the decline of wild fry catch and with inadequate supply from local hatcheries. However, self-sufficiency is ...
Optimum stocking density and feeding level for laboratory‐reared early‐stage silver therapon (Leiopotherapon plumbeus) larvae
(Wiley, 2020-10-23)
Growth, survival and feeding of early‐stage silver therapon Leiopotherapon plumbeus larvae reared at different stocking densities and feeding levels were examined. Larvae (8 days post hatch (dph); 0.38–0.50 mg body weight ...
