Webevaluated smaller-scale variations in benthic charac-teristics within a culture site (1) under long lines vs. between long lines or (2) in areas with juvenile bivalves (i.e. at the beginning of the growth cycle) vs. bivalves of commercial size. Such variation should be taken into account when evaluating the influence of Webrequired to detect this variation. First, we focus on a small spatial scale and quantify whether breeding success or fledgling survival varied consistently among individual …
