| certainly do not worry that they are too deep, fill less if you must but i wouldnt, id be totally happy, if your not going to add air be aware that your stocking rate and feeding rate will need to be less anyway. youll get less growth if you oiverstock it. i still swear that the deeper ponds wont result in less fish or growth than a 3 and a half foot one (you should be adding supplementary food) but if you do vetoe the air your cutting growth or stocking by atleast half. think economics of that one!! youve paid for the ponds, add air for cheap is like having twice the ponds again!!!
its its this sort of thing, overstocking, no air, leading to lack of nutrition and big swings etc is what leads to disease. its a ball starting to roll once you do that.
if fish farmers abided by the right rules of stocking feeding, waterQ etc,
you more than likely wont get disease and get die off or them coming into shut you down or dispose of fish. sometimes youll get good officers and othertimes ones that dont know much.
in oz, if we lose 5% or more we are bound to notify them. even when its the case that you know your aerator or whatever broke down.
only new farmers totally scratch their head about losses. most experienced ones atleast have an inkling.. even if its not the direct cause it may be linked to the cause..being a bit slack, running low on time, cutting corners, not watching feeding rates etc.
so the trick for you if not doing the air lift or wheels is to not stock too heavily and not expect huge yeilds right away or youll push things into disease. remember if its and extensive system, its an extensive stocking.
thats not to say that you wont be happy with what you get though but as time goes on youll bump it up there..
if you start out smart youll start somewhere in the middle with your yeilds.
iu think youll be stoked either way. |
