Effects of different sex ratios on maturation, fecundity and hatching rates of ablated Penaeus monodon wild stock
; Primavera, Jurgenne 
; (Fisheries Research Society of the Philippines, 1980)
; (Fisheries Research Society of the Philippines, 1980)
The minimum number of males per female that would still ensure high maturation, fecundity and hatching rates in Penaeus monodon broodstock, is determined. Wild stock P. monodon were stocked in 4 m diameter circular tanks ...

Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
; Primavera, Jurgenne ; (Science and Technology Information Institute, Department of Science and Technology, 1980)
; (Science and Technology Information Institute, Department of Science and Technology, 1980)
The survival, spawning, fecundity, and nauplii production of ablated Penaeus monodon females reared in flow-through broodstock tanks with white coralline and black sand substrates for 62 days, were assessed. Prawns exposed ...

Mass production in concrete tanks of sugpo Penaeus monodon Fabricius spawners by eyestalk ablation
Primavera, Jurgenne ; ; (Fisheries Research Society of the Philippines, 1978)
; ; (Fisheries Research Society of the Philippines, 1978)
Two batches of 196 and 181 P. monodon females were ablated on one eyestalk in March and July 1977, respectively, and a control batch of 180 unablated females was stocked in July 1977. The females were stocked with males ...

Effect of different stocking densities on survival and growth of sugpo (Penaeus monodon Fabricius) in a milkfish-rearing pond
Primavera, Jurgenne ; ; (STII-DOST, 1976)
; ; (STII-DOST, 1976)
Employing a direct stocking monoculture method, postlarval P. monodon were stocked in 8 compartments of a shallow milkfish rearing pond at densities of 1, 2, 3 and 4/sq m with replicates. Feeding was exclusively natural ...

Primavera, Jurgenne ; Quinitio, Emilia T. (Crustacean Society, 2000)
; Quinitio, Emilia T. (Crustacean Society, 2000)
A total of 24 morphological abnormalities associated with the Runt-Deformity Syndrome (RDS) is reported for the first time in 17- to 18-mo old F<sub>3</sub> generation <i>Penaeus monodon</i> (>40 mm CL) belonging to ...

Effect of different stocking combinations on growth, production and survival of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricius) in polyculture in brackishwater ponds
; Primavera, Jurgenne (Elsevier, 1981)
(Elsevier, 1981)
Milkfish (Chanos chanos) and prawn (Penaeus monodon) were stocked in 500 m2 earthen ponds from 12 November 1978 to 15 March 1979 at the following combinations: 2000 milkfish fingerlings per ha (treatment I); 2000 milkfish ...

Light color and ovarian maturation in unablated and ablated giant tiger prawn Penaeus monodon (Fabricius)
Primavera, Jurgenne ; (Elsevier, 1992)
; (Elsevier, 1992)
The effect of light color (green, blue and white fluorescent lights, with natural light as a control) on maturation in intact and eyestalk-ablated Penaeus monodon was tested in 12-m<sup>3</sup> broodstock tanks. Size and ...

Survival rates of different Penaeus monodon Fabricius postlarval stages
Primavera, Jurgenne (National Science Development Board, 1976)
(National Science Development Board, 1976)
Four different postlarval stages (P<sub>11</sub>, P<sub>15</sub> , P<sub>21</sub>, and P<sub>25</sub>) of P. monodon were stocked in suspension nets at the rate of 200 fry/sq m with 3 nets for each postlarval stage. Pond ...

Effect of tagging on maturation and survival of ablated Penaeus monodon in painted and unpainted tanks
Primavera, Jurgenne ; (San Carlos Publications, University of San Carlos, 1989)
; (San Carlos Publications, University of San Carlos, 1989)
A study was conducted to determine the effects of tags and tank color on reproductive performance and survival of pond-reared Penaeus monodon after eyestalk ablation. In 1986, the best over-all reproductive performance was ...

Preliminary results of feeding aquatic macrophytes to Penaeus monodon juveniles
Primavera, Jurgenne ; (Elsevier, 1989)
; (Elsevier, 1989)
Penaeus monodon juveniles (PL<sub>50</sub>) were fed live and decaying aquatic macrophytes and a commercial grow-out pellet (40% crude protein) in 80-l glass tanks over a 30-day period. Growth and survival were significantly ...
