Sorry for the long absence. I have been busy with my research, and will be MIA intermittently.
Youtube is really and interesting place to look for amusing stuff on agriculture. Look up the link below on Langat Aquatech's high density catfish farming.
http://www.youtube.com/watch?v=EGlIS-8QBgoThe video is old, but still quite impressive. The least dense tank contained 10,000 fishes, with a target weight of around 125g (8 fish per kg). That's a hell lot of fish for such a small tank. Going by the rate above, we're looking at 1,250kg of fish; @ retail value of RM5.00 per kg, that's about RM6,250 sitting there. Now the average growth rate of Clarias catfish to reach 125g is about 3-4 months, so that's about 3 cycles in a year. I believe that about 10 tanks can be house on say half acre space, with generators, shed house, etc. Therefore, 30 harvests of RM6,250 each = RM187,500.
Anyway, back to business.
MrFarmer:
The peck marks? Birds are attacking your papayas. They should be near ripe. The papayas, I mean.
As for Cavendish, yea, lots of process required to market the fella. This variety rarely ever does turn yellow on its own, unless almost rotten. It also doesn't ripe evenly, even after exposure to farnesene or carbide. You will need a cold room to achieve even ripening. But export market is very good. In Australia, they sell for about AUD$3.50 a kg off-peak (roughly RM13.00 here).

Foreigners are permitted to purchase land in Malaysia. But I would suggest you get a good lawyer, aside from a good real estate negotiator. This is because not all land are designated for plantation-based agriculture, and there are some which actually specify what kind of crop is permitted (although it is usually ignored by the growers and the authorities). Also, some properties carry with them special clauses (eg. TOL land which is leased land from the government, land of limited statutes of ownership, native customary rights land etc.). You will need a good and honest lawyer to help you through this, especially in dealing with the government.
Anyway, it's been 2.5 months now since I've landed in Sarawak. I must say, Kuching+Samarahan is a pretty flat land. Very heavy clay in the higher elevations, and really swampy peat soils in the lower grounds. But overall, it is actually a pretty fertile land. Just the agronomic aspect need to be given more emphasis; noticed that agronomic practices are almost non-existent.
Also, checked out much of the wet markets around town. Aside from the usual stuff seen in Peninsular, there were a lot more other varieties of vege and fish being sold. It isn't often you find fiery Habanero chili peppers being sold in such abundance in one place, or huge Pacu (piranha) fish being traded eagerly. The variety of fish species, in particular really caught my attention. I believe that Sarawak (well at least Samarahan) has a good potential for freshwater aquaculture, as long as the downstream activities are also equally developed (eg. smoked catfish, pickled fish, etc.).
Sunlight hours in Sarawak is extremely long. I estimated about 6.5 hours of full sunshine hours here; but it may just be due to the time of the year. Weather patterns, however, is very volatile. It can be blistering hot for a moment, and then suddenly a massive thunderstorm will roll in. Might be tied to the lay of the land, and its located to the South China Sea. The mountain ranges fringing Kuching + Samarahan, in my opinion, sort of act as a funnel, channeling in the water vapour and trapping them over the two towns.
I have yet to really sample any local species for agriculture purposes, but I believe I may have found a potential catfish candidate to hybridize with the existing version of the hybrid to create a super hybrid of sorts. The current variety does grow very fast (reaches 1kg in 8-12 months), but apparently does not taste as good. Hopefully, by including more genetics of local species, the new hybrid will have better taste while retaining its high growth rate.
