Yet another moult and alas another kill , the yabby’s have plenty of food and there water is well aerated the water temp is probably a little high but I think that makes the more sluggish than any thing .
I have recently introduced the other female back into the adult yabby’s tank and suspect that the males kill each other to eliminate the competition for mateing , they didn’t eat this one its tale had been bitten and they were in the process of eating its shedded shell.
I have read on the net that some guy has found a way of eliminating caniblism but he is keeping a tight lip on how he is doing it I think the new cross breed that produces male only juveniles is being used thus eliminating the competition factor and allowing higher stocking densities with out the losses ,thats my theory any way.
Mike’s Place in Dampier
Hi Guy’s
at Sue’s insistance here is a picture of my place in Dampier
you can see the new roof, this is great no more leaks in cyclones.
I have to save up for the concrete driveway, to finish it off
the pic was taken in August, the roof is now dusty, and the front lawn, (weeds) are now dead!
and the backyard still green, it’s our Oasis
nice and shady, and bounced back from the shredding metted out by cyclones early in 2006,
the cyclones actually provided a lot of mulch, which was put to good use.
and the chooks, they’re full grown now, 4 eggs per day, easy to look after and ya just can’t beat fresh eggs!
so what’s this got to do with Aquaculture
I hear you ask!
nothing ……….. actually
Mother moults no loses
I checked in this morning on the juvenile stock to see if there was any movement , it was no surprise not to see any !
The juveniles only seem to come out at night I guess the fish I have in there keep them on there toes
I am not sure if this is normal behaviour but I think its a safe bet to say that it is a defense mechanism.
I have cracked gravel in the tank wich seems to be great for juveniles as there is heaps of spaces between the gravel for them to disapear into , not such a good idea though if I had to transfer them to another tank as it would be almost impossible to catch them unless I made some kind of mini trap for them.
Any way while I was checking I noticed that the mother had moulted I checked to see if there were any juveniles left on it but the empty shell was clean I am assuming that they all made it ?
then again the fish may have had a good breakfast !!!
The PH in both my systems is 7.5 it doesn’t seem to move from there it may be the reason they are moulting so much and around spawning as there is an excess of calcium in the water , the plants in the grow beds are growing good as well wich is surprising me , one of the strawberry plants has flowered and the hot and spicy oregano has tripled in size .
