Embayment fish community biomass at maximum biomass weight class versus maximum biomass weight class. Total fish community biomass at maximum biomass weight class (k) versus maximum fish community biomass weight class (h) for drowned-river mouth (open circles), pelagic-protected (black squares), and littoral-protected (grey triangles) embayments. Points represent 3-year means ± standard error (SE). Embayment codes follow Figure 2. Fish Community Response to Embayment and Habitat Characteristics The models that provided the best, most parsimonious fit to the data included total phosphorus load, area, the interaction between total phosphorus load and area, and percent vegetation.

Annual fish relative abundance (total fish catch per unit effort; #·min-1) in July, 2001–2003, versus mean percent vegetation for drowned-river mouth (open circles), pelagic-protected (black squares), and littoral-protected (grey triangles) embayments.

NSS were created for each embayment-year by transforming all fish weights by log base 2 [32]. The sum of transformed weights in each size class was plotted against the transformed weight of the heaviest fish actually recorded in that size class (sensu [33]).
