| yeah ive just worked out what your measurements are..
I dont get the 25 foot surface area though but anyway i can see what your doin there.
its good to see what your dealing with and doing. i musunderstood you before thinking you meant metres.
i dont know mikes take but also while 4 foot may be fine for fry and grow out, i prefer for fish ponds to be a bit deeper.
id be asking more why would prefer you go shallow. i know shallow ponds can grow fine, people say the light penetrates that depth better..no offence intended to you at all mike but i reckon theres more to it than light.
tell her to hide the keys of those dozers for a night itme joyride.
really if they are 4 foot at deepest then you will have them even more shallow at the other end and you have to have a freeboard.. they wont be fully full.
(you should get them to put a taper in and not leave them flat bottomed.)
i prefer ponds about 1.8 to 1.4m and not less.
shallow ponds= cool quick, warm quick. ie. they fluctuate more are less forgiving.
predators can eat them out easier also.
a farm next door to where i worked failed, one big reaon was cause the ponds got attacked by predator birds. it seemed they put as many ponds in as quick as they could, now theyre full of bottom growing weeds.
shallow ponds with slow sloping banks are even worse at a lot of long legged varieties can feast on your efforts.
dont let that panic you if theres not a lot around to eat them but it is a bad point of shallow ponds.
with deeper ones your getting more water for land area also.
for me shallow ponds limit the ability to breed and grow in a larger time window.
you can spend more on what land you do own and itll be ok.
pleas eremember how much more work many many ponds are, even though you get more control ove rpairings in theyre own pond you can expect them to provide less than the real shallow ones too.
if its gonna cost you more than you wnat5 it to, then you can keep going as is, itll still be ok.
though if they can scrape em deeper while yhey are there ,for not much more dollars, id do that.
id assume theyre going by the hour. tell em to chunk it up deeper to begin and manicure last.
this might be a time when its better to have 3 done right then get them in to redo once your up and running with water and fish on the property.
well anyway thats my advice.
anyone prefer 3 and 4 foot over five and six feet deep in regards to farming? |
