Dietary lipid requirement of whiteleg shrimp Litopenaeus vannamei juveniles cultured in biofloc system
(Wiley, 2020-06)
An eight-week feeding trial was conducted to evaluate the contribution of biofloc on dietary lipid requirement in whiteleg shrimp Litopenaeus vannamei. Five diets with graded levels of dietary lipid (45, 60, 90, 120 and ...
Survival, growth and biomass of mud polychaete Marphysa iloiloensis (Annelida: Eunicidae) under different culture techniques
(John Wiley & Sons, Ltd, 2020-04-20)
Polychaetes are commercially exploited as fishing bait and supplemental diet to crustacean and finfish broodstock. However, scarcity of supply and biosecurity issues limits its use. Polychaete aquaculture has become the ...
Improved survival and growth of silver therapon Leiopotherapon plumbeus early juveniles through co‐feeding with Artemia and commercial feeds
(Wiley, 2021-12)
This study examined the effects of co-feeding Artemia and commercial feeds on survival, growth and fatty acid composition of silver therapon Leiopotherapon plumbeus early juveniles. Triplicate groups of 36 days post hatch ...
Evaluation of dietary fermented tuna by-product meal as partial replacement for unprocessed tuna by-product meal in fishmeal-based diets for juvenile olive flounder Paralichthys olivaceus
(Springer, 2022-12-06)
This study examined the effects of feeding fermented tuna by-product (FTBP) on the growth, non-specific immune response, liver and intestinal morphology, and disease resistance of olive flounder Paralichthys olivaceus. ...
Grazing periodicity, grazing rate, feeding preference, and gut examination of early juveniles of abalone Haliotis asinina–fed five benthic diatom species
(Springer, 2022-06-03)
This study evaluated the suitability of five diatom species (Amphora sp., Cocconeis sp., Navicula ramosissima, Nitzschia sp., and Tryblionella sp.) as food to abalone Haliotis asinina early juveniles (5-mm shell length). ...
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....
