has an important component of echinoderms in the incidental catch, which is
extracted and discarded maimed or dead, or their habitat destroyed by the low
selective fishing gear (Fig. 7.8).
Unfortunately, estimating the echinoderm discards in fisheries has been difficult. In this sense, Kelleher (2005) mentions that both fishers and observers tend to
focus on commercial species and recognized animals. There is a tendency to group
tunicates, sponges, echinoderms, hermit crabs, worms and corals with jellyfish and
