They require large ponds ranging from 1 to 5 hectare in the areas used for farming fish. An extensive aquaculture systems requires no supplemental feeding or fertilisation is provided, harvest from 500 to 2000 kgs/ha.]]> 2017-09-26 08:46:48 UTC https://padlet.com/michael_baker2/53zgujs0kab5/wish/191139278 https://padlet.com/michael_baker2/53zgujs0kab5/wish/191140934 Growth is limited by available food. (Zooplankton feeding on pelagic algae or benthic animals such as crustaceans and mollosks). Tilapia for example filter feed directly on phytoplankton which makes higher production possible.]]> 2017-09-26 08:53:00 UTC https://padlet.com/michael_baker2/53zgujs0kab5/wish/191140934 https://padlet.com/michael_baker2/53zgujs0kab5/wish/191147697 Fish species that you would find in a extensive aquaculture systems are species like filter algae fish like tilapia, benthic feeders such as carp and catfish and zooplankton or submerged weeds filter like grass carp. ]]> 2017-09-26 09:16:30 UTC https://padlet.com/michael_baker2/53zgujs0kab5/wish/191147697 https://padlet.com/michael_baker2/53zgujs0kab5/wish/191150732 2017-09-26 09:28:33 UTC https://padlet.com/michael_baker2/53zgujs0kab5/wish/191150732
