Few bAsic Rules of fish ponds...
for fishing have to be at least ______ acre because the pond can't support a _______ (with prey and predators) for blue gills fish don't go over ______ acres |
at least ONE acre bc MINI ECOSYSTEM
3 ACRES |
|
|
CONstructed...
SURFACE AREA= needs to be less than ______ft deep prob with spring fed? what temp does it need to be? |
how much sunlight is hitting it
10 feet (6-8ft is good) it's too cold between 75 and 80 F (if high enough alt and have a big enough volume spring fed is possible but news to be over 70 F or not TROUT) |
|
|
you want a _______ pond, for this you need ________land, also known as __________ ____)
|
WATER SHED, CONTOURED, SURFACE RUNOFF
|
|
|
need to fill a 1 acre pond with ____ - _____acres of watershed per _____ acre of pond
TYPES OF PONDS |
7- 15 acres, per one acre
HILL POND= collect water from a watershed and is built between hills and dammed up on one side -Leakeage: to avoid place the pond where hter is adequate clay in soil )at least 20%) DEEP PONDS= don't want it too deep no more than 10 ft, 6ft is good, even 4 ft is enough -STRATIFICATION: below a point there is typically no oxygen in the water and the temp drops SPRING CREEK FED PONDs |
|
|
When would be closer to a 7 acres, 15?
|
Vegetation in summer pulls out a lot the water (TRANSPIRATION)
PASTURE WATERSHED = 7 acres FOREST WATERSHED= 15 ACRES BOTH= somewhere in between |
|
|
Drainage =
|
standpipe, needto invest in one if not your stuck
|
|
|
when is the best time to build a pond?
|
Late in the year (september - october) bc it is AGAISNT THE LAW IN TN to have a pond full of water w/ no fish.......bc of mosquitos
|
|
|
PROPER KIND OF FISH NEEDED FOR POND....
|
BALANCE OF PREDATORS AND PREY .....based on when you stock them
|
|
|
who are the predators and who are the prey?
|
pred= LARGE MOUTH BASS
prey = BLUE GILL |
|
|
when do you stock each?
what is the ratio? |
Bluegill= November (about 1,000 per surface acre)
Bass= next spring June (about 100 per acre) 5 to 10 to 1 ratio (bass start out a year younger than the bluegill) |
|
|
There are only 5 permissible species to add with the bass and blue gill, what are they?
|
1. BLue gill...can use 25% of your blue gill as RED EAR
2. Bass 3. RED EAR 4. GRASS CARP 5. CATFISH |
|
|
what do the grass carp and catfish do (describe each)
|
GRASS CARP (not for fishing)
- control aquatic weeds -Its and Asian Carp that eats only vegetation (INVASIVE EXOTIC) *can nay stock ones that don't breed = TRIPLOID stock only 8-40 per acre CATFISH _channel catfish at about 50/acre -wont reproduce themselves, need little hide hole to nest in (don't rally want them reproducing a lot) |
|
|
A lot of ponds in TN are less than an acre, too small but channel catfish can provide fishing
-in a catfish only pond.... |
will do supplemental feeding
no more than 600 an acre if catfish pond |
|
|
more fish a re killed by _______ , can safely not feed fish for ___ - _____ weeks
|
OVER FEEDING from ppl being out of town
3- 4 WEEKS (Hard to starve a fish) |
|
|
if we don't do anything but fill, stock and harvest the pond properly we can expect that our pond will contain about___________ lbs fish per SURFACE acre Just from ______ energy.
|
100 pounds
suns energy actaully not a lot of fish |
|
|
how many bass will you have if thats all you do?
|
about 5-6 so have to be careful when fishing
|
|
|
what can you do to increase the bIOMASS of the pond? how many ponds of fish will you get?
|
FERTILIZE ...number on back of bag = LIMITING NUTIRENTS
|
|
|
what is the limiting nutrient?
how many pounds of it per acre? what does it do? |
PHOSPORUS
about 8 lbs per acre per month during warm months sun and it causes water to get greener making phytoplankton which zooplankton eat which fish eat = food chain ....wil increase standing crop up to 300 lbs per acre (if start fertilizing you have to keep up with it, bc fish will quit growing but still reproduce = overpopulation |
|
|
HARVEST RECCOMENATION?
|
keep 1 punt of bass for every 5 pounds of bluegill that you remove
natural ratio = 5:1 -remove to keep the balance - do not just harvest one type of fish *problem is thats a lot of bluegill! better solution dont kill the bass (fishing...return to pond when caught) |
|
|
alternative to the 5:1 ratio =
SLOT LIMIT (size limit) |
protecting certain fish for overall success
-12-16 inches for LMB (largemouth bass) = don't kill these -these midsize bass are what keep the population (or 14 to 18?) going -anyfish in that 2 lb range shouldn't be killed |
|
|
What is a way to assess an existing pond to tell if it is in good shape?
when should it be done? |
SEINE CHECK
fine mesh net to catch lil fish July - Aug.. after spawning  |
|
|
what to look for in siene check?
|
1. GOOD YOY bass= geren ....mini
(do more than one Haul, every haul you want to have more than 1 bass, tells you if they are reproducing 2. range of blue gill sizes whats bad= no bass, stunted blue gill size, tadpoles (which are bad bc the bass would eat them if there is no blue gill ) |
|
|
in a wuater acre pond-cathfish only you want ____ catfish per____
|
600 per acre
|
|
what is this ?
how many per acre? |
Blue GILL
1,000 |
|
what is this? how many per acre?
|
catfish 50/acre
catfish only pond = 600 per acre |
