Crawfish Update

Cooling off for Larry & Moe

They like to have water pouring on their head. There are five left out of the initial seven, the two just disappear. I will need to get two males to replace those that is missing.

Crawfish Feeding Time Lapse

These Crayfish is very elusive and will hide the moment they saw me coming. I use the Samsung Galaxy S5 with Framelapse apps and leave the phone shooting for about 45 minutes at 1 frame per second.

Next time I will try not to feed them and get the camera ready before feeding, it may give better footage.

Anyway here is the timelapse footage.

Crawfish Tank & A 15mm StrainerBell Siphon

It has been sometime since I last tried Crawfish, that time I was not ready and don't know what to expect of this crustasean . With some time to spare this afternoon and many surplus tanks and pipes, I decide to make a tank for it and at the same time making a small 15 mm siphon to test. Killing two birds with a stone.. as they said it.

I am using existing water source to water the new addition and right return tank as support. Surplus Dickson bars or angle irons make a rack using return tank as support. This arrangement make the distance for water return to be very small. It will be difficult to make a siphon.

Using one of the surplus smaller tub which already has holes in it for water inlet and previous 25mm siphon. The 25 mm siphon I use a tank adapter and pvc piping to make a stand pipe since I am not using this siphon, it is just to close the hole.

The other hole was for 15 mm pvc piping, this is just right for the smaller siphon I am  testing. I made this siphon same as the 20 mm StrainerBell just that it is using smaller parts.

The shorter return creates problem with existing fittings, I had to cut it to length so that siphon outlet just above water line in the return tank.

For now I'm setting the siphon to operates at water height of 11 cm, no extender use. I do not want to use too much water since there is no hydroton in this tank. I think Crawfish don't need that much water, and having a flood and drain can keep them continuously supply with fresh water.

This siphon will drain water to about 2 cm, it is preset that way due to the vent on the inverted vent cowl used. BTW it is a 2 inches vent cowl and uPVC pipes, the 20 mm Siphon make use of 3 inches uPVC.

That's the 11 cm water mark, hope Crawfish will not manage to escape.

Water inflow is a trickle, and I "tee" from existing feed to the right growbeds on my CRAFTS set.

That's the completed 15 mm StrainerBell siphon and water feed.

Outlet flushing, I will need to test these. Since it is smaller the operating margin is much less. Water required is also very much less, making this siphon a good candidate for a gutter growbed system.

The completed crawfish tank with smallest siphon I made to test.

Next I will need a few Crawfish... :)

Fresh Water Red Claw

Visited nearby aquarium shop to get some fish for my Ornamental Set Prototype No. 2, so happen that this place stock many of these Red Claw Crayfish of various sizes. Price range from Rm 4.00 to RM 10.00 each. The smaller one at RM 4.00 is a good buy, but I refrain from getting any because I am not prepared for these yet.

Below are just some photos of those Red Claw for show.

Crayfish Aquaponics

Feeder tank has its water level constantly fluctuating, not a good place if you are a fish.. this is where I decide to get the Crayfish, sometimes they were called Crawfish, Crawdad or even fresh water lobster. Not sure its same as Yabbies as in Australia.

Just received few to tryout and lets see ... these are easily breed and in feeder tank they should be okay with water not full all the time.

Just learned from the person that provide these crayfish. Looking at photo below the top crayfish is female and the bottom is male the different is in the circle. The pincers with reddish colour is male and without is female. Lots to learn on this crayfish, especially how to take care of them.

Next would be breeding these crayfish and produce for self use.

Few of the crayfish hiding in pvc pipes.

Need to remove most few more Tilapia and leave only a handful to ensure mosquito is under control. Crayfish don't eat mosquito larvae.

Yabbies

When to International Aquatics trying to see whether they have Jade Perch... nope... not a chance.. you out of luck .. we not going to do that fish.... at the moment.

Ok... then I'll have those Yabbies please.

Five Yabbies in a bag,, they are scavenger so any dead fish... will be taken care off.. by these guys.
