Distributions of diversity values for each AMLR survey. H' (SOLID BAR) represents the Shannon-Wiener Diversity 

 index, and VlOPEN BAR) represents evenness, R (SHADED BAR) represents richness. (Richness was adjusted to 

 the scale of the other indices by dividing by 10.) (A) Diversity of fish community at stations sampled during the 

 1986-87 survey, based on numerical abundance; (B) diversity of fish community at stations sampled during the 

 1986-87 survey, based on biomass; (C) diversity offish community at stations sampled during the 1987-88 survey, 

 based on numerical abundance; (D) diversity offish community at stations sampled during the 1987-88 survey, 

 based on biomass; (E) diversity of fish community at stations sampled during the 1988-89 survey, based on 

 numerical abundance; (F) diversity of fish community at stations sampled during the 1988-89 survey, based on 

 biomass.
