Effetti del regime alimentare e di illuminazione sulle gonadi del riccio di mare Paracentrotus lividus (Lmk, 1816).

Paracentrotus lividus (Echinodermata: Echinoidea) adult specimens were reared in a recirculating aquarium under controlled conditions up to 4 weeks to evaluate the effect of the light and feeding regime on gonad growth. Gonad yield and reproductive conditions were influenced by feeding regime, while light regime proved to have no effect on them.
