Primavera, Jurgenne 
; (Institut National de la Recherche Agronomique, 1978)
; (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, ...
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 ...
