Successful artificial reproduction of the African carp: Labeo parvus Boulenger, 1902 (Pisces: Cyprinidae)

The effectiveness of hormonal treatments to induce gamete emission in Labeo parvuswas investigated in two spawning seasons (2007 and 2008). Brood fishes measuring 15 to 30 cm were gill netted in the Ouémé River (Benin) during their migration to their spawning habitat and then held in captivity (ponds). Captive fish (N = 30 males and N= 37 females) were treated with GnRHa combined with a dopamine...

Bioindicators for siting the carpet clam Tapes decussatus L. farming in Mediterranean lagoons

With a worldwide increase in shellfish aquaculture and awareness towards sustainable practices, this paper provides a method based on bioindicators for identifying a suitable site for rearing the carpet clam Tapes decussatus in a lagoon of the South Adriatic coast of Italy (Varano lagoon). Although the species is naturally widespread in Italian coastal lagoons, it was in fact absent from Varano lagoon. However, we...
