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 ...
Field efficacy evaluation of a formalin-inactivated white spot syndrome virus (WSSV) vaccine for the preventive management of WSSV infection in shrimp grow-out ponds
(Elsevier, 2021)
A shrimp grow-out trial was conducted in four 700 m<sup>2</sup> earthen ponds in Dumangas Brackishwater Station of SEAFDEC Aquaculture Department, in Iloilo, Philippines to evaluate the efficacy of a combination of immersion- ...
Growth performance, production and economic viability of Indian white shrimp (Penaeus indicus H. Milne Edwards) fed with varying dietary protein levels
(Wiley, 2022-03)
The growth efficiency, productivity and economic viability of Indian white shrimp (<i>Penaeus indicus</i>) fed with diet containing 40% (CP<sub>high</sub>) and 34% (CP<sub>low</sub>) crude protein (CP) levels were determined ...
The influence of monosex rearing on gonad maturation and reproductive behavior of Indian white prawn, Penaeus indicus broodstock
(Elsevier, 2022-02)
Monosex culture was proven to be an effective rearing method for grow-out, but in a closed-cycle hatchery, males and females are usually reared communally in tanks until maturation. This study determined the effect of ...
Determination of poly‐β‐hydroxybutyrate assimilation by postlarval whiteleg shrimp, Litopenaeus vannamei using stable 13C isotope tracing
(Wiley, 2021-02)
A preliminary study was conducted to demonstrate fate of the bacterial storage compound poly-β-hydroxybutyrate (PHB) once ingested and degraded in vivo in crustaceans. The 2% supplementation of <sup>13</sup>C-labeled ...
Biodiversity in mangrove-derived aquaculture ponds in Dumangas, Iloilo, Philippines
(Science and Technology Information Institute, Department of Science and Technology, 2021-02)
Large tracts of mangroves have been converted into aquaculture ponds and the consequent loss of biodiversity has been much decried. This paper shows that high aquatic biodiversity is retained in mangrove-derived aquaculture ...
An innovative biofloc technology for the nursery production of Pacific whiteleg shrimp, Penaeus vannamei in tanks
(International Network for Natural Sciences, 2022-10-09)
Nursery production of shrimp is usually done in small ponds; however, the use of small and circular tanks with plastic liners is gaining popularity. From an industry standpoint, there is still a need to assess how nursery systems can be of benefit to the shrimp production cycle. Hence, the use of small circular tanks coupled with the incorporation of biofloc technology was assessed in terms of its viability during the nursery production of the Pacific whiteleg shrimp, Penaeus vannamei. A 450m<sup>2</sup> plastic lined circular tank was installed and prepared for the stocking of P. vannamei postlarvae (PLs) at a density of 500 PLs per m<sup>2</sup>. Biofloc was produced and maintained throughout the nursery phase using brown sugar as carbon source at a carbon to nitrogen (C:N) ratio of 10. Water quality was monitored daily, while presumptive Vibrios were enumerated weekly. Sampling for growth was done at the 14<sup>th</sup> day post-stocking and weekly until harvest on the 30th day. The different water quality parameters were within optimum levels required for shrimp growth. Presumptive Vibrios were dominated by the yellow colonies. At the end of the nursery phase, there was 100% survival and the shrimp attained an average body weight of 1.26 g and a feed conversion ratio (FCR) of 0.43. Our results indicate that the use of small circular tanks with biofloc during the nursery production phase of whiteleg shrimp is feasible and can be incorporated in the grow-out culture of this shrimp species....
Inclusion of live mud polychaete (Marphysa iloiloensis) in the feeding regime improved the hatchery performance of domesticated Indian white shrimp (Penaeus indicus)
(Elsevier, 2023-03-07)
A 60-day feeding trial was conducted to evaluate the effect of inclusion frequency of hatchery-bred mud polychaete, Marphysa iloiloensis, as part of a combination diet on the reproductive performance and larval quality of ...
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 ...
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) ...
