The toxicity of hydrogen sulfide (H2S) to the larvae and eggs of the Javanese carp, Puntius gonionotus (Cyprinidae) was determined using a flow-through bioassay. The eggs and larvae showed similar low tolerances to H2S. The EC50 value for the eggs was 2.8 µg l-1 H2S. One hundred percent of the eggs...
