Fishy mis Adventures Part II Trout Rapture

One fish, two fish, dead fish....*sigh*.....

Recall from Part I, when we decided to take out a few fish to eat, my thought was, "what can it hurt?"  Well, apparently, it can hurt a lot.

The next day, January 4, I found a floater in the tank.  I dont know what caused the fishs death.  In reading about humanely treating fish, I came across a lot of catch-and-release articles.  A couple of things I learned - first, try not to take the fish out of the water at all.  Its like suffocating them.  Next, if you must handle the fish, make sure your hands are wet.  If you touch a fish with dry hands, you are effectively "burning" the fish by removing some of its protective slime.  Also, the protective slime is part of the fishs immune system, so besides causing the fish pain, you are damaging its immune system.  I read on several different sites, that often, if you release a fish and dont handle it properly, it might swim away, so you think the fish is going to live, but it actually swims away and ends up dying.  See photo below.  Note that this is on a standard-size dinner plate (10" or 12"? Im too lazy to go measure it).

Big Dead Fish
Knowing that, when we removed the fish from the water, we tried to put the ones we were going to eat back into the water immediately.  Also, we did not touch the fish with our hands.  I dont know what caused this fish to die.  Maybe it was just shock.  But, it turns out, it was about twice the size of any of the fish we ate!  I think it was the granddaddy trout in our tank. 

OK, so one fish down.  I think I should be down to 30 or 31 fish at this point, so everything is still good, right?

Wrong.

Today, I go down to take care of the dogs, and there are FOUR dead fish floating around.  And a sort-of-alive one hovering near the top of the tank.  The nitrate levels are off the charts.  The water level was a little low, so I added some water, but the nitrite levels were still out of range of my little chart, so I did a 50% water change.  During the water change, yet ANOTHER dead fish comes floating by....AHHHH!!!  Frustration.

The only "good" thing about todays experience is that it has been unseasonably warm all week, with today being the warmest day yet.  It was about 65-70 degrees outside today, so at least I didnt have to do this in subfreezing temperatures.  Its a rather wet and messy process.  It did, however, take me three tries before I found a hose that wasnt frozen, but at least I didnt have to carry the water into the house in buckets.  My back is too old for that kind of work. 

Anyway, heres another picture of fish carcasses.  :-(

This is starting to seem like a rather morbid blog....

More Floaters
Now heres where the trout rapture comes in....this is weird.  My son and I were shining the light in the tank, and it seems like there are only two fish swimming around!  Hopefully, the rest are just so healthy and fast that theyre avoiding the light every time we move it and hiding in the corner (is there a corner in an oval tank?  whatever).  Usually, we can see a bunch of fish shadows swimming around, but now we only see a couple, so my son is convinced the other fish have been raptured. 

I still dont know exactly what happened, but Im guessing one fish died of shock and floated in the water long enough to contaminate the water and kill the other fish.  I just checked the nitrite level again, and although its a lot higher than it should be, at least it seems to have gone down a lot since the water change.  Im hoping that if I dont feed them for a day or two, the level will stabilize.

On a happier note, my plants are still alive.  Actually, I dont know that I would call the plants "happy," but they are alive.  Theyre a little yellow, and growing really slowly, but they are still alive.  If I decide to continue with this, I will have to come up with an artificial light solution.  Here are a couple of pictures taken January 3.  I think I planted the seeds at least two months ago, so you can see that the growth is extremely slow.  I think if I had planted these outside in June, they would be about this size within a week or two.

The good thing is that I didnt lose very many plants when we had the super-sub-zero temperatures a few weeks ago.  There is a gap in the dog door that lets in raw, cold air, and I was afraid it would freeze my plants.  I think it got down to about 40 degrees Fahrenheit, so it was pretty close. 

Bed 1 - Strawberries on the Right, Lettuce and Herbs on the Left

Bed 2 - Sickly Tomato Plant and Some Broccoli and Herbs
Well, thats about it for now.  Not much excitement this winter until recently, so there really wasnt anything to report.  Hopefully the next update will have better news!

Thanks for stopping by!  :-)

Plant Pictures and Water Data

Here are a couple of pictures of the growbeds today.  The lettuce in growbed #1 had stopped growing and started wilting right after it sprouted.  I think this is because of a heat wave we had.  That was the same time the mature lettuce we had outside had turned bitter and started bolting, which is what lettuce does when it gets too hot.  I was about to give up on the lettuce, but once the weather cooled down this weekend, it started to grow again.

Growbed #2, which had tiny pea sprouts on Sept 1, now has lots of peas and beans, and I think even some tomato sprouts.

?
Growbed #1-beans, peas, lettuce and basil

Growbed #2 - beans, peas and tomatoes
??I had to add a little bit of ammonia last week because the nitrate levels dropped.  I need to keep the nitrate levels up until I get the fish.  Once the fish are introduced to the tank, their waste should produce enough ammonia to keep the nitrate levels up.  Here is the data Ive collected since starting the tank.  Note that our tap water pH is about 6.5.

Fishy mis Adventures Part I The Feast

WARNING - some of this might be a little graphic for the PETA set.  Or for squeamish people (like me) who prefer to buy their meat already dead and wrapped in cellophane.
------------------------------------------------------------------------------------------------------------
After watching what appeared to be a few rather large fish swimming around in the tank for the past couple of months, we decided to take a few out for dinner.  The water is still too dark to see the fish very well, so we werent sure if they were really that big, or if it was a trick of the light, but what could it hurt, right?

So, on January 3, my son and I pulled a few out with a net, but they were way too small, so we put them back.  We did this a couple of times, until we finally came out with a few that were smallish eating size.  Not wanting to allow my fish to suffer by letting them die of suffocation, we put them in a bucket of water and took them upstairs.  I had done a few searches on how to "humanely" kill a fish, and the most popular way I found was using something that stabs them between the eyes, stabs their brains, and supposedly instantly kills them.  I didnt trust my skill at getting just the right spot through the skull, so I decided I would try the next best thing (IMO)...chop off the heads.  I knew killing the fish would be the least pleasant part of the entire aquaponics process, but its got to be done. 

The Six Fish We Decided to Eat
First of all, this method turned out to be very messy.  In hindsight, this should have been very obvious.  Usually, by the time a person cleans a fish, it has been dead for at least a few minutes, so the blood circulation has stopped.  Chopping the head off a live fish - blood spurts everywhere, all over my kitchen counters and all over us.  So, first lesson - dont chop the heads off of live fish.

Fish out of Water
Yuck
Ready for the Grill...or so We Thought

Next, just like the proverbial chicken running around with its head cut off, the trouts nervous systems are still active, even after they are dead.  Flopping around, gills moving.  Ricky even found a little tiny fish heart that was still beating several minutes after the fishs death.  Gross.

Thinking the drama is over, we put the beheaded and cleaned fish on a cedar plank to be grilled.  Apparently, the nervous system was still active for longer than we thought, because when my husband went out to the grill to check the fish, a couple of the headless fish had "jumped" off the plank and onto the grill.  Weird.

Well, either way, dinner was good.  Fish, rice, corn, and naan.  I was so excited to taste the fish that I almost forgot to take the picture.  So, here is the half-eaten, grill-jumping fish.  Yum.

One Dead Fish and Blossoming Beans

Went to Vegas last weekend and put an automatic feeder on the tank.  Came back and had one floater.  I wasnt really surprised. I was actually expecting closer to a 50% mortality rate when I thought I was going to get fingerlings, so this isnt so bad.  The only problem was that Im not sure how long it was dead (it was pretty stiff), so I dont know how long it was decomposing and contaminating the water.  I took ammonia and nitrite readings and they were a little high, but not too bad.  I held off feeding until the next day, then my readings were normal, but the water is still a little cloudy.  The rest of the fish seem to be doing OK, though.  They love feeding time.  I turn on the light underneath them and I can see a bunch of them start swimming all crazy when I drop the food in. 

BTW, Fishcam is dead.  Uh, I guess my Ziplock idea wasnt so airtight after all.  At least not the last time (and I do mean "last time") I used it.  At least I got one sort of good little video.

The bush beans that think theyre pole beans are finally starting to blossom, which means I should hopefully have some green beans soon.  Peas are doing OK, but no flower buds yet.

The beans are still growing crazily toward the window, as expected, to the point that theyre pretty much lying flat on the ground.  Not sure what that means for bean production, but I guess well see.  I put a full spectrum light in the room and leave it on for a couple of hours a day (when I remember).  Hopefully that will help even them out a little.  Here are a few pictures.
