Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock fish.
The idea: Grow the salmon indoors to reduce exposure to parasites, warming waters and algae blooms that threaten the fish grown in farms in open waters near shore — and in turn reduce the fish ...

Fish can be manually stripped of eggs and sperm by stroking the anaesthetised fish under the pectoral fins towards the anus causing gametes to freely flow out. Environmental manipulation : Thermal shock, where cool water is alternated with warmer water in flow-through tanks can induce spawning.
The aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
