5 trout harvested on Friday, average 916g, largest 1090g. I've started feeding them a mix of 6 and 8mm pellets.

I've got a Classica automatic feeder set up to give them 150g twice a day, plus I usually give them another 200g manually. The water has been around 10-12C lately, so they aren't eating as much as when it was warmer. I'm testing the feeder out to make sure it is reliable enough to leave operational when away.
When I fed them 100g of pellets this morning, one of them jumped up and banged into the feeder with its mouth when all the pellets were gone... so it might be time to make an on-demand feeder for them I think.

I'm not sure if they have figured out the timing of the autofeeder and are waiting for it, but large numbers of them are immediately onto the pellets as soon as they are sprayed into the water from the feeder. Maybe they just recognise the sound and rush over to get the pellets before the others do ;)

The trout farm I bought my trout from had feed trained their trout. It seemed to work pretty well, they just used a 2-liter bottle turned upside down with a pendulum on it with a red marker on it and said they train them from hatching that red means food because when they are smaller they use red ketchup bottles to dispense their food, so they get used to seeing the red and associate it with food then when they are in the bigger tanks they get the demand feeder and just keep hitting it until they get enough food to fill them up.

After the hottest July on record in town, with 5 days over the previous record max, the water temps have been high enough for the trout to be eating well. I'm still picking capsicums, rather unusual for the middle of winter!

Unfortunately, it is still extremely dry, so the wallabies, wallaroos and kangaroos have been attacking the AP veg due to there being nothing much else to eat. We've been buying (very expensive) hay for them to distract them from the AP and my wife's plant nursery. They demolished all my rhubarb when we were away for a few days, but fortunately it has sprung back well, after I put some netting over it. The stomped all over the spuds, and ate some of the leaves, so that crop is a bit of a write-off. The cabbages were also significantly chewed on, but we've been eating what was left. Fortunately, we've been eating excellent cauliflowers and broccoli, and we are about to start picking romanesos, as there are harder to get to for the roos.
I've also been harveting a few trout, the largest one a week ago was 1.45kg with the average of 9 = 842g.

This chunky 1.5kg trout was so big around the middle I had trouble lifting it out of the FT! Quite a bit shorter (only 40.5cm) than many in this weight range, but 15cm top to bottom... we ate half of it last night, some more on toast for lunch today, and I'll make some trout cakes with the remaining 1/3.

I harvested 8, largest 2039, average 1.33kg- average pulled down by 3 "small" ones, 601, 634 and 880g. They do look quite small after handling the big ones!

I don't know if it's the biggest trout or not, but I haven't heard of any larger.

Another 9 harvested tonight, largest 1680g, average 1230g. There are still plenty of big ones in there, but also some that are quite small... some might call them plate sized ;)
Maybe they'll get a chance to grow a bit as I remove the big ones over the next couple of months before it gets too hot.


The rhubarb was completely trashed by hungry wallabies and wallaroos in July, pic below, and then they ate more of the stems in August

The stems all died off, but fortunately new stems grew back really well, and I'll be cutting some to eat and sell this week.

About 18 months since I got them as 50-80mm fingerlings- I managed to keep them through last summer, but lost a few dozen due to heat, even with a water chiller. I haven't decided on whether I'll keep any smaller ones over summer this year, but maybe not if it's going to be another ridiculously hot summer.

Yea, with the weather playing silly burgers and likely to be a bloody hot dry summer. If the spring so far gives any indication I think you'll be pushing the proverbial up hill!

That is a good size.
I am keeping an eye on our water temp which was 18C at 7am and 20C at 12.30pm.
Don't think that our trout will be that size, they loo a lot smaller although it is hard to see in the water as they are hiding at the back under the grow bed until you feed them. But then they are too quick.

Since I've just been advised that my job has been outsourced to Hyderabad, I'll have a bit more time on my hands and will be starting to build a new stand for 5 GBs shortly. Fortunately I have already purchased the GBs and most of the steel, so it wont cost me too much more to complete, other than for the poly fittings.
I'll probably remove the blue drum shade cloth filter and use the new GBs for the extra filtration I've needed with the large fish mass I currently have.

I'm planning to do a lot of seedling raising in some of the new GBs for my horticulturist wife, who has found some work in a nursery, so hope to have a small income stream from that.
I'll post some pics as it progresses.
