Identifying nursery habitats is of paramount importance to define proper management and conservation strategies for flatfish species. Flatfish nursery studies usually report upon habitat occupation, but few attempted to quantify the importance of those habitats to larvae development. The reliance of two sympatric flatfish species larvae, the European flounder Platichthys flesus and the common sole Solea solea, on the estuarine food web (benthic vs. pelagic) was determined through carbon and nitrogen stable isotope analysis. The organic matter sources supporting the production of P. flesus and S. solea larvae biomass originates chiefly in the benthic food web. However, these species have significantly different δ13C and δ15N values which suggests that they prey on organisms that use a different mixture of sources or assimilate different components from similar OM pools (or both).

底栖食物网支持在河口育苗栖息地生产同域比目鱼幼虫

确定苗圃栖息地对于确定比目鱼物种的适当管理和保护策略至关重要。比目鱼苗圃研究通常报告栖息地占领，但很少有人试图量化这些栖息地对幼虫发育的重要性。通过碳和氮稳定同位素分析确定了两种同域比目鱼幼虫，即欧洲比目鱼 Platichthys flesus 和常见的唯一 Solea solea，对河口食物网（底栖与远洋）的依赖。支持 P. flesus 和 S. solea 幼虫生物量生产的有机物质来源主要来自底栖食物网。然而，
