The lack of size-suitable live food for small-gaped fish larvae is a major impediment to their growth and survival. Rotifers are viable live food that can bridge the gap between the dependence of such fish larvae from their endogenous yolk to larger-sized live feeds. The present study focused on developing Filinia longiseta, a very small local roti...

Aquaculture of the endemic silver therapon (Leiopotherapon plumbeus) in Laguna de Bay is now seen as a valuable instrument to improve its diminished stock and fisheries. Its dietary preferences during its early life stages are not yet well understood leading to low survival. Hence, the present study examined the effect of different natural live fee...

A new island record of Ideopsis juventa luzonica Moore 1883 is reported with photos of specimens collected from Fuga island, Philippines.
Presentation
Leiopotherapon plumbeus, locally known as ayungin, is a native fish species in the Philippines known to be endemic in Laguna de Bay. Ayungin used to be the top catch in Laguna Lake, however, due to overfishing, fishpen construction, introduction of invasive species and exploitation of juveniles, catch of ayungin has declined in recent years. For se...
Presentation
With the declining population in the wild, Leiopotherapon plumbeus or ayungin has been regarded as one of the priority native species for conservation and has been the subject for aquaculture studies in recent years, However, larval rearing remains a challenge, with low survival observed in captivity. This study was conducted to determine potential...

Chitala ornata (J.E. Gray) (Osteoglossiformes: Notopteridae) has since established abundant and nuisance populations in Laguna de Bay. A fundamental prerequisite for the development of management strategies for invasive species like C. ornata is a full understanding of its life history characteristics including sexual dimorphism. In the present stu...

A full understanding of life history characteristics of invasive species is a fundamental prerequisite for the development of management strategies. Chitala ornata (knifefish) have established highly abundant and destructive populations in Laguna de Bay (Philippines). In the present study, we examined the reproductive biology of C. ornata with the...
