I had to go,
The Master Auld
Awaits, you know.
Can not be stalled
North wind doth blow,
Here is a scrawled
Goodbye, you’ll know.

How To Calculate The Weight Of Your Fish The simplest method I have found is to make estimations based on the length of the fish. What you do is place something in your pond that you know the length of, such as a decoration or even just a stick. As the fish swim past the item, you can see how long they are compared to that item. You can even take photos as they go past, so you can look at the pictures to help with the comparisons. You then make a list of all the fish you have, and how long they are. Now that you have their lengths, you can use the following average lengths to figure how much they weigh. This may seem complicated or laboursome, but you really only need to do it once or twice a year.

How To Calculate The Dry Weight Of Your Food
First you need to figure what container and scoop works best for you. I personally use a peanut butter jar and it's lid as the measuring cup, however many people use a big plastic jar and a real kitchen type measuring scoop. Whatever measuring scoop you use, put 10 scoops of food into a container and measure it with a postal scale. Then take that weight and divide by 10, and you have a pretty accurate weight of one scoop your food. Write that on the scoop, so you know how many scoops your fish need. For an example, I found that my peanut butter jar lid holds 1.75 oz of my pellet food.
Homemade Koi Food
I have seen a number of large healthy koi that were fed regular koi pellets PLUS large amounts of table scraps. I have become convinced that feeding your koi fresh foods is essential, because processed & dried foods seem to destroy the nutritional value of the ingredients. There are lots of recipies on the internet of how to make your own koi food.
For the food I make, I take koi pellets and run them thru my blender dry, this makes a powder. I set that aside, then blend up a bunch of vegetables to make what looks like a milkshake. I then mix that by hand with the powder, plus wheat germ, wheat flour, corn meal, and other random stuff to thicken it up. I split that up into portions that are the right size for 1 week of feeding. Then I move one portion to the refrigerator, and pull off chunks daily to feed to my koi. Not very scientific, but my fish like it. Also I feed cooked shrimp, and cooked tilapia.
Winter Break - No Feeding
A koi's metabolism is mostly based on the temperature. At temperatures between 60 and 87, you should feed the full daily amount. At temps between 56 and 60, you should cut the feed rate down to 0.75% or less. After the water temp drops to 52 and below (and stays down there), you should stop feeding until the temp rises back above 52 and stays there or above. The koi go into a slow state and mostly sit on the bottom of the pond during this cold time, and they don't process the food very well. This is a normal part of their yearly cycle, they build up a lot of fat in the fall to carry them through the winter. Your filter will mostly die off also, so in the spring when you start to feed again, feed lightly for a while to build the bacteria up again.
Hot temperatures -- reduce feeding
One of the problems we have in Arizona is the water temperature can rise very high, I have seen temps as high as 96 in my tanks. One summer, the water stayed at 96 for about a month and a half. The koi reduce the amount they eat when the temp gets above 88, so if you notice this, then cut back on the amount you feed.
