Brackishwater: salinization/acidification of soils/aquifers. Both: market competition, especially for export produce; feed and fertilizer availability/prices; conflicts/failures, social disruption.
2. Integrated agriculture-aquaculture (rice-fish; live stock/poultry-fish; vegetables - fish and all combinations of these) | As freshwater above, plus possible consumer resistance to excreta-fed produce; competition from other users of inputs such as livestock excreta and cereal brans; toxic substances in livestock feeds (e.g., heavy metals) may accumulate in pond sediments and fish; pesticides may accumulate in fish.
3. Sewage-fish culture (waste treatment ponds; latrine wastes and septage used as pond inputs; fish cages in wastewater channels) | Possible health risks to farm workers, fish processors and consumers; consumer resistance to produce.
4. Cage and pen culture, especially in eutrophic waters or on rich benthos (carps, catfish, milkfish, tilapias)]]> 2017-09-26 08:51:47 UTC https://padlet.com/michael_baker2/o9z5ma80n7pt/wish/191140574 https://padlet.com/michael_baker2/o9z5ma80n7pt/wish/191141183 2017-09-26 08:53:53 UTC https://padlet.com/michael_baker2/o9z5ma80n7pt/wish/191141183 https://padlet.com/michael_baker2/o9z5ma80n7pt/wish/191142028 2017-09-26 08:56:39 UTC https://padlet.com/michael_baker2/o9z5ma80n7pt/wish/191142028 https://padlet.com/michael_baker2/o9z5ma80n7pt/wish/191149037 Most fish can be farmed semi intensive.
