The capacity of a natural mangrove system in Ibajay, Aklan province, central Philippines to process shrimp pond culture effluents was assessed through analysis of mangrove community structure and 24-hr monitoring of water ...
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 ...

Primavera, Jurgenne ; (BFAR, 1976)
; (BFAR, 1976)
A resume is presented of the practical considerations involved in establishing a sugpo pond culture operation, as a guide to fish farmers, extension workers and others interested in producing marketable sugpo in the ...
Intensive prawn farming in the Philippines: ecological, social, and economic implications
Primavera, Jurgenne (Springer Verlag, 1991)
(Springer Verlag, 1991)
The benefits of intensive farming of the giant tiger prawn Penaeus monodon in the Philippines are discussed in relation to the environmental costs. Ecological effects include mangrove conversion into ponds; use of antibiotics ...

; (Institut National de la Recherche Agronomique, 1978)
Spent Penaeus monodon females were tagged around one eyestalk with numbered brass tags, stocked in a concrete tank with males, and periodically examined for ovarian rematuration over a six-month period (February to August, ...
Mud crab pen culture: replacement of fish feed requirement and impacts on mangrove community structure
Primavera, Jurgenne ; ; ; Lebata, Ma. Junemie J. ; ; ; (Blackwell Publishing, 2010)
; ; ; Lebata, Ma. Junemie J. ; ; ; (Blackwell Publishing, 2010)
Brackishwater pond culture has been a major factor in mangrove loss in Southeast Asia, hence, the need to develop environment-friendly technologies such as mud crab Scylla (Portunidae) culture in mangrove pens exists. This ...
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 ...
