Abstract:The clam Polititapes aureus is one of the most abundant shellfish species in southern Tunisian waters. Its potential future commercial value is key resource for artisanal fisheries. This study was conducted to assess stocks and develop a management plan for natural clam populations along the Sfax coast. The results revealed significant density fluctuations across the study area, which was divided into six main sites, with stock density ranging from 0 to 6 ind.m⁻² and biomass values varying between 0 and 41 g.m⁻². Total biomass reached 70.1 tons, with an abundance exceeding 16.58 million individuals across 3,867 hectares. Sampled individuals measured between 3 and 32.9 mm in size. Key environmental factors were identified, with several abiotic parameters found to have a significant impact on the distribution of clam species. Conservation guidelines are proposed to restore its stocks to sustainable levels

Title:Stato attuale di Polititapes aureus (Mollusca: Bivalvia) nella zona costiera di Sfax, Tunisia (Mediterraneo centrale)
Abstract:La vongola gialla Polititapes aureus è una delle specie di molluschi più abbondanti nelle acque della Tunisia meridionale. Il suo potenziale valore commerciale futuro è una risorsa chiave per la pesca artigianale. Questo studio è stato condotto per valutare gli stock e sviluppare un piano di gestione delle popolazioni di vongole lungo la costa di Sfax. I risultati hanno rivelato significative fluttuazioni di densità in tutta l’area di studio, che è stata suddivisa in sei siti principali, con una densità di stock che varia da 0 a 6 ind.m⁻² e valori di biomassa che variano tra 0 e 41 g.m⁻². La biomassa totale ha raggiunto 70,1 tonnellate, con un’abbondanza superiore a 16,58 milioni di individui su 3.867 ettari. Sono stati identificati i fattori ambientali chiave che hanno un impatto significativo sulla distribuzione delle specie di vongole e proposte linee guida di conservazione per riportare gli stock a livelli sostenibili.
