| Q. |
Will
my pond or lake hold trout? |
| A. |
Ponds
that are spring fed or at least 20 feet deep are the most suitable for
trout. Surface temperatures should remain below 75 degrees F throughout
the summer. Shallow ponds will be fine if there is enough spring water
moving through the pond to keep it cool. Often it is less expensive to
run well water through a pond rather then have it excavated to 20 feet.
Also the exchange of water is beneficial to the trout, approximately 50
gal/min per acre for ponds less than 10 feet deep and 25 gal/min per acre
for ponds in the 10 to 20 foot depth. |
| Q. |
How
many trout can I put in? |
| A. |
Stocking
densities vary greatly. The worst case scenario would be a pond with no
exchange of spring water. Its rate would be 300 lbs of fish per acre.
Remember that 8"-10" fish weigh 4 per pound and 10"-12"
weigh 2 per pound. Now if the pond has an inflow of spring water the rate
at which it can be stocked will increase dramatically, if 300 lbs per
acre is going to be exceeded supplemental feeding with trout chow will
be necessary. Example: A 1 acre pond with 50 gal/min entering it would
hold 2000 lbs of trout, (supplemental feeding would be necessary). If
a surface aerator is added to this pond it would hold 10,000 lbs of trout. |
| Q. |
How
much should I feed them for optimum growth? |
| A. |
The
simplest way to gauge feeding is to cut them off when the feed response
(excitement level) drops by about 50%. Technically they should be fed
about 1% of their body weight at or around 50 degrees F water temperature
and 2% at or around 60 degrees F. |
| Q. |
When
is it time to stock? |
| A. |
Anytime
the surface water temperatures are below 70 degrees F and the closer to
50 degrees F the better. Consequently most stocking is done from October
to June. |
| Q. |
How
do I transfer them to my pond? |
| A. |
Large
orders, more than 400 6"-8" trout or more than 200 8"-10"
trout will be delivered in our tank truck. Small orders can be picked
up at the farm. Trout will be placed in plastic bags with oxygen and are
good for several hours of travel. |
| Q. |
Do
I need a permit from the M.N.R.? |
| A. |
If
trout are going to be put in a private pond or lake, where the fish cannot
escape, nor is it in a floodplain, no permits are necessary.
If an individual is stocking
public waters or private waters that are connected to the public watershed
(for fish movement), then a permit should be acquired from their local
M.N.R. office. Cost is $50.00 and is good for 3 years. If private ponds
have a screened outflow and inflow they should be in compliance and
a permit would not be necessary. The M.N.R. would not likely approve
any stocking that would compete with a wild strain that might already
exist in a public waterbody. Example: They would not allow rainbow or
speckled trout to be put in a lake that had a population of lake trout.
Pure Springs Trout Farm can often assist in acquiring a permit in the
rare case that one is needed.

| Q. |
How
fast will they grow and how long do they live? |
| A. |
Growth
depends on food supply. If trout are being fed artificially they will
grow 2 to 3 times as fast as they do on a natural food source.
| Example: 1 year old rainbow trout
would weigh 10-14 oz |
2
year old " " " " 2 - 4 lbs |
3
year old " " " " 4 - 6 lbs |
4
year old " " " " 6 - 8 lbs |
| 5 year old " " "
" 8 -10 lbs |
6
year old " " " " 10-12 lbs |
7
year old " " " " 12-14 lbs |
8
year old " " " " 14+ lbs |
Speckled trout
grow at a slightly slower rate than rainbows and only live for about
5 years.
|
| Q. |
Should
I stock rainbow or speckles? |
| A. |
Rainbows
are the most popular as they are the hardiest, live the longest and least
expensive. However we do stock thousands of speckled trout every year.
Speckles are very colorful - the males turn a brilliant crimson every
fall. |
| Q. |
Will
they reproduce naturally? |
| A. |
It
is not common for domestic hatchery trout to reproduce significantly,
but not unheard of. Certain waterbodies seem to be more conducive to natural
reproduction. |
