Nocillado, Josephine; Palma, Peter ; Wang, Tianfang ; ; Levavi-Sivan, Berta ; Elizur, Abigail (Elsevier, 2022-05)
Late maturation and large size at maturity are significant challenges when administering hormonal treatments in captive broodstock. Here, we report the potential of yeast, Pichia pastoris, as a vehicle to orally deliver a ... -
A technical and economic evaluation of supplemental feeding strategies for Nile tilapia (Oreochromis niloticus L.) reared in lake-based cages
Romana-Eguia, Maria Rowena R.; ; Aya, Frolan ; ; (AquacultureHub Inc., 2022-03)
Tilapia cage farming in eutrophic lakes uses low stocking densities since tilapias can thrive mainly on natural food or minimal supplementary feeding. For semi-intensive Nile tilapia cage culture, feeding strategies to ... -

The influence of monosex rearing on gonad maturation and reproductive behavior of Indian white prawn, Penaeus indicus broodstock
Santander-Avancena, Sheryll; Monteclaro, Harold ; Estante-Superio, Erish ; ; Traifalgar, Rex Ferdinand (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 ... -
Biofloc technology (BFT): A promising approach for the intensive production of ornamental fish
; ; ; Pakingking, Rolando V., Jr.; Caipang, Christopher Marlowe (Bioflux (Bioflux SRL), 2021)
Biofloc technology (BFT) is an approach in the rearing of fish and shrimp as a means to support intensive culture, maintain optimum water quality, recycle the nutrients and reduce feed costs. The technology is primarily ... -
