For silver dollar enthusiasts-
In an interesting paper [Pagezy & Jegu 2002. Bull.Fr.Peche Piscic. 364:49-60, free online], the authors describe the feeding ecology and cultural appreciation for the fish (“kumaru” - large silver dollars) and the fishery for them in the Wayana region of French Guyana.
Image 1 shows the 3 fish taxa discussed (names of genera not all up to date).
Image 2 shows the aquatic plant the fishes show the highest association with: Mourera fluviatilis (Podostemaceae), a recurrent element in the ecology of many herbivorous Serrasalmidae.
Image 3 shows depictions by children (ages 8-13) of the fishery, showing both bow-and-arrow, and standard line and hook fishing. Figs 2 and 4 show awareness of fish consumption of Podostemaceae plants on the rocks, whereas Figs 5 and 6 show awareness of fish consumption of terrestrial fruit falling in the river from riverine fruit trees.
Rarely do we see such a vivid depiction of both the fish ecology and the cultural appreciation for them by the locals.
Hopefully you will like it too.
