Abstract:
- The red porgy, Pagrus pagrus, is a protogynous hermaphrodite
sparid of increasing interest to the aquaculture industry. The first efforts for the
intensive culture of the red porgy started at the IMBC in 1989, when
broodstock and fry were caught from the wild and acclimated at on land
installations. The present work describes data on i) reproduction (study of
gametogenesis, age of sex reversal and sexual maturity, spawning strategy), i¡)
larval rearing (stocking density, feeding regime, water quality, timing of the
developmental stages), iii) ongrowing (growth rate, conversion index, mortality,
water requirements) and ¡v) disease problems related to the intensive farming at all stages of production
