08 aquatic animal products (ccpr) 041 diadromoous fish (wd) (ccpr) The diadromous fishes in general migrate from the sea to brackish and/or freshwater and in the opposite direction. The anadromous species spawn in fresh water (streams, small rivers and brooks) e.g. several salmon species, whereas eels spawn in the ocean. Some species, such as trout, are domesticated and do not migrate. They are bred in fish farms in ponds, mountain streams etc. The latter species especially may be exposed to pesticides through compounded fish feed and also through water pollution. The fleshy parts of the animals and, to a lesser extent, roe and milt are consumed. requires discussion
