In this book, the classification of ostracods by Muller is used the genus names by the Poulsen classification are cited in parentheses only when appropriate. The author protests against the irresponsible shuffling of scientific names, and hopes for the revival of the Muller classification. In addition, the author believes that Cypridina luciferin is the proper name of this substance that is not necessarily bound to the genus name.

Cypridina luciferase is not available commercially at present. However, Cypridina luciferase can be readily extracted from both live and dried Cypridina, and the crude extract, after dialysis, can be used in the measurement of Cypridina luciferin. Live Cypridina can be collected in Japan, and the ostracod can be cultivated in laboratory (see the last part of Section 3.1.2). Dried Cypridina is available from certain sources, including the author s laboratory.

Rudd Scardinius erythrophthalmus), a medium-sized cyprinid species, is an herbivorous the bulk of its diet consists of plants and algae. However, small invertebrates, such as nematodes, larvae of a freshwater shrimp Atyaephyra des-maresti), larvae of small, littoral chironomids Paratanytarsus sp. and Cricotopus flavocinctus), and particularly microcrustaceans such as ostracods, are included. 

Roach (rutilus rutilus), a medium-sized cyprinid fish, is a planktonic and benthic species, feeding mainly on cladocerans (D. longispina), detritus, plant debris, amphipods (Echinogammarus sp.), filamentous algae, and ostracods. Roach can thrive on poor quality, even polluted water and displays more capacity of adaptation to different kinds of food than rudd [62].
