Walmer Tilapia Hatchery

The first batch of my tank bred  red strain Mozambique Tilapia (Oreochromis mossambicus)
have now reached about 5 cm each. They seem better adapted to the tank environment and take both commercial feed and duckweed quite well. I am still keeping the ordinary grey ones though and may play with the idea of crossing them to see what happens.

Major disaster this morning in the Tilapia Hatchery. Water levels in the outside 1 kl went lower than the bubbler leaving fish starved for oxygen. Sadly these fish are now contributing their nutrients to the compost heap. Perhaps I lost half the fish, there are still many quite healthy. I also lost two gold fish that had become quite big in the tank.

I have now changed the bubbler set up in such a way that it can never be exposed above the water level. But the system is being tweaked and adjusted with every mistake I make. I have made a lot of mistakes!

Walmer Vinyard

I have been working for a few weeks now on cleaning up the vine on my east boundary.

The vine has been there for a long time. When we moved in 13 years ago it was already very established and giving small purple blackish fruit. The I count three vines, with a least one on the neigbours side of the fence.

I intend to make wine from these grapes come Feb or March next year.

The best gues so far is that the cultivar is a Catawaba. This cultivar comes from America. When I googl Catawaba, it does come up with a number of sites trying to popularise the wine.

Interestingly though, when I went to the Nursery a few weeks ago to buy 4 new vines, the only red cultivar that they had available was Catawaba. Perhaps the nursery man their knows a thing or two about suitability to the Port Elizbeth climate.

Which brings me to the Theescome wine estate that i visited last week. Sandra there is making wines from four cultivars – Pinotage, Cabernet Sauvingon and two whites. here vinyard is only two hectars in extent!

Climate therefor does not seem to be an impossible impediment in Port Elizabeth.

I can be worked around!

Walmer Tilapia Hatchery

Major disaster on Sunday. I heard a crashing noise. When I got to the hot house the glass aquarium had broken and the red tilapia breeding group were all over the ground flapping around. Managed to save them but I think we lost the fry the broody mother was carrying in her mouth.

I bough this tank second hand about a year ago for about R200.00. Just to replace the broken glass would cost me about R600.00. I t does not seem worth it. I have never built a fishtank before and the chances of me getting it wrong are quite big. Perhaps I will live without the glass aquarium. (for now)
