The trout are harvested by catching them in a net in the dark, and then tickled on the tummy until they don't try to escape, at which point they can be lifted out of the water with minimal to no struggling, and then whacked on the head with a rolling pin. This less stressful method of dispatch (no thrashing about trying to escape from my hands) leads to better tasting fish, and less stress on the person doing the harvesting too, except when I whack my thumb! The largest trout in the 2015 batch was just over 1.2kg (1.05kg after gutting and cleaning), with a lot in the 700-900gram range, along with a range of smaller ones.

73 Rainbow Trout in a buried 4500 litre fish tank (holding a bit over 4000l on average) were harvested in mid Dec 2013. The largest of them was 686g, pictured below, and average weight was 432g. The system has a ~2000 litre sump tank (background, under cover), with 9 * 500 litre grow beds, variously planted with silverbeet, parsley, celery, garlic, beans, asparagas, coriander, beetroot, spring onions, chives, tomatoes (160kg picked between xmas 2013 and 17th July 2014 from 8 plants), strawberries, eggplant, capsicum, Egyptian walking onion (aka tree onion), and a dwarf banana that has become huge (no bananas yet). Snow and heavy frosts in July-August 2015 really knocked the banana about for a few months, but late in 2015 is appears to be looking healthy again.
The aquaponics system is proving to be a lot more productive than growing in the soil, and uses a small fraction of the water. In summer 2012/13 the in-ground garden had to be abandoned due to the excessive amount of water required just to keep the plants alive, meaning we were close to running out of domestic water, which is only sourced from rainwater collected from the roof.
In hot weather keeping the system water under ~22 degrees for the trout was quite a challenge. Lots of ice was added to the fish tank on hot days, up to 65kg on a hot day, and the sides of the grow beds and grow media were mostly shaded. King Parrots discovered the aquaponics vegetables on 6th Nov 2013, so I've had to enclose the greenhouse and outside growbed with netting to prevent any more attacks on the vegetables. Outside growbeds and wickbeds in the new system have netting over them to protect the vegetables from birds, including our chooks, who love chard.
