Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
; Primavera, Jurgenne
; (Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Experiments were undertaken to assess the survival, spawning, fecundity and nauplii production of ablated P. monodon females reared in flow-through broodstock tanks with white coralline and black sand substrate for 62 days. ... -
Notes on ovarian rematuration of ablated sugpo (prawn) Penaeus monodon Fabricius
Primavera, Jurgenne; (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
To what extent spent P. monodon females can remature and spawn successive broods is an important question in terms of recycling spawners in a commercially viable operation. Corollary to this is the quantity and quality of ... -
Notes on the induced maturation and spawning in four-month-old Penaeus monodon Fabricius by eyestalk ablation
Primavera, Jurgenne; (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
The ablation technique consisted of making an incision across the eyeball to allow free flow of fluids while holding the prawn under water, squeezing the eyeball contents outwards, and pinching hard the eyestalk tissue. ... -
Viability of Penaeus monodon eggs after simulated transport conditions
Primavera, Jurgenne; ; (Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
P. monodon spawners, transported from maturation pens suffer from stress which in turn may lead to lowered spawning rate or fertility. Spawning the females in the maturation site and transporting the eggs to the hatchery ...
