ARTIFICIAL BREEDING IN PISCICULTURE, AND BREEDING OF RARE AND ENDANGERED SPECIES OF FRESHWATER FISH

The important role of aquaculture (pisciculture) is demonstrated using data on development of the world fishery. It is noted that the present-day level of harvesting biological resources of the World Ocean has reached its upper limit. Against this background, the proportion of the global fish catch contributed by pisciculture has almost doubled (from 13.4% up to 26.3%) since the early 1990s. According to information from FAO, more than 180 countries in the world have taken initiatives in pisciculture.
