The End of the Rainbow - The Demise of Fatty McFish

FISH
In two days, I will be making the trip to Liley Fisheries in Boulder to get a new batch of fish.  Fatty McFish is  (was) a big fish in a small tank, so it was time to make room for the tank's future occupants.

For me (and probably most people, as evidenced by this post), this is the least enjoyable part of aquaponics - "harvesting" the fish - but, it must be done.  I read a bunch of opinions on the most humane way to kill a fish.  I went with two ideas -
1 - put the fish in a bucket of ice water so its circulation will slow down
2 - smack it in the head with a hammer

Well....let's just say that I won't be doing the smack in the head with a hammer.  It didn't work after one smack...or two...or...Anyway, I think you get the picture.  Obviously, I didn't smack hard enough, but that fish had a tough head.  I ended up taking a sharp knife and sawing off the head.  Wish it had been faster.  Sorry, Fatty.  :-(

Next time I will probably use more ice in the ice water.  Or maybe try the method mentioned in the forum linked above and use clove oil in the water to anesthetize the fish.

At any rate, Fatty's suffering is over and he will be dinner this evening.  He was pretty big.  I should have gotten a tape measure, but I was trying to finish it quickly, so we'll just have to take a guess at his length...looks like over 15 inches.  Actually, it was a "she," but we got used to calling it "him."

Here's a short video of him swimming in his tank last night.  BTW, the noise in the background is my dog drinking water.  He's crazy like that.

PLANTS

Unidentified Growing Object - 

Last year, my husband planted a bunch of acorns to see if he could grow some oak trees.  The planters were sitting above my grow beds.  This spring, once it finally stopped snowing and the temperatures got above freezing, a strange woody plant sprouted in one of my grow beds.  Once the leaves got big enough to be identifiable, I realized one of the acorns must have fallen into the bed.  There is now an oak tree growing with my strawberries and cilantro.

Coconut Husk (Coir) Planting Material

All of my plants in the grow beds end up with very shallow, weak roots.  My husband bought me some coir, made of coconut husks, to see if I can get a stronger root system.  Coir is being used in many places instead of peat moss.  When I soaked the blocks of coir, as instructed, I was a little worried because it just looked like a bunch of potting soil ending up in the water.  However, I put about an inch of the stuff in a section of one of my grow beds, and it seemed to hold together pretty well.  I planted a few basil and cilantro plants...and I think something else, but I can't remember what.  We'll see if this allows them to establish better than starting out directly in the gravel.

Sprouts in Coir - 29 June

That's it for now.  I will post some pictures of the new batch of fish soon.  Hopefully this trip will be a little less...eventful than the last!
