Fresh water and fisheries: Methodology
Author(s): Naim Saglam*
Freshwater aquaculture production in 2011 was 44.3 million tons or 29% of
world fisheries production. Roughly 95% of this production was from Asia – China
was the leading country. Ponds are the common culture system, but raceways,
cages, net pens, and water re-use systems are important. Seed stock for growout
is produced in hatcheries from farm-reared brood stock. Fertilizers, feeds and
mechanical aeration increase production in ponds. Competition with agriculture
for land and water, wetland destruction, water pollution, and lack of fish meal and
oil for use in feeds could limit aquaculture [1]. There is an effort to avoid these
impacts.
Aquaculture, freshwater or marine, is dependent upon good water quality to
sustain maximal fish growth. Ammonia and nitrate are toxic to fish. NH3 should
be kept at levels below 0.. View More»
