Feeding regimes in relation to reproduction and survival of ablated Penaeus monodon
Primavera, Jurgenne 
; ; (University of the Philippines at Los Baños, 1979)
; ; (University of the Philippines at Los Baños, 1979)
Pond-reared P. monodon were stocked in four 12-cu m flowthrough maturation tanks at 25 males and 50 females per tank; females were unilaterally ablated. The combinations of feeds for the morning and afternoon rations were ...

; ; ; ; Quinitio, Emilia T. ; ; Primavera, Jurgenne (CSIRO Publishing, 2009)
Ranching, stock enhancement and restocking are management approaches involving the release of wild or hatchery-bred organisms to enhance, conserve or restore fisheries. The present study, conducted from April 2002 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 ...
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 ...
Effect of salinity on survival of Metapenaeus anchistus juveniles and subadults
Lebata, Ma. Junemie Hazel L. ; Primavera, Jurgenne (University of the Philippines in the Visayas, 1997)
; Primavera, Jurgenne (University of the Philippines in the Visayas, 1997)
Survival of Metapenaeus anchistus (De Man) juveniles and subadults at 5, 15, 25, 35 (control) and 45 ppt salinity levels was determined and compared. Salinity levels lower than 35 ppt level were prepared by diluting pure ...
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 ...
A review of mangrove rehabilitation in the Philippines: successes, failures and future prospects
Primavera, Jurgenne ; (Springer, 2008)
; (Springer, 2008)
From half a million hectares at the turn of the century, Philippine mangroves have declined to only 120,000 ha while fish/shrimp culture ponds have increased to 232,000 ha. Mangrove replanting programs have thus been ...
