Microscopy course: Practice and Theory was another fun and educational day

On Friday 29 September I will drive to the high north at 16.00 u. I have to make a stopover in Overlangel, to pick up the microscopes and booklets from Willy van Summeren, board member of the Nishikigoi Association of the Netherlands . The ride lasts 3 hours and I am a bit on the road. It is raining so hard that I have poor visibility and tomorrow I have to go all the way back to the beautiful south.

Immediately it appears that the entry level is very different

At 23.00 u Tiebo and I prepare the last things and the beamer-laptop combination is tested. Good preparation is half the job. I go to sleep with peace of mind, although it takes a while before I fall asleep. Healthy tension and enthusiasm keep me awake.

Everyone is ready

At 9.15 you are back on location and the coffee pot is turned on. Alie de Boer has also arrived and offers a helping hand today. Gradually the students flow in and I am curious to see what comes up with this course. Some know each other from the previous course: Health: Prevention, control and diagnosis of 9 September.

We start with a piece of theory

The microscopes brought to the table are on the table and the proposal round can begin. Immediately it appears that the entry level is very different.

Two hands to hold the koi well and with which hand do you iron?

Some often make scraps and for others it is completely new. However, everyone has the same goal: to increase the welfare of the Koi.

Know your tools

We start with the basics. Which microscope is suitable and which is not and what should be on it? What is necessary and what is luxury? The best is yet to come and that is the practice. There are three major practical assignments in the course with, of course, the fish themselves.

a piece of mucous skin that will move due to the heat of the lamp is not an Ichtyobodo

Jan has brought six Koi, of which we can take a scrape.

Here's what to do

Yet it appears again that it is not too bad. The koi are not very large and that means that they are very mobile and fast. In the end, everyone succeeds in making a smear. There is also cooperation, because you are short of hands. Two hands to hold the koi well and with which hand do you iron?

Concentration is scanned for unwanted living organism

Now it's looking for parasites. Everything that moves is suspicious. Distinguish the air bubbles from the Trichodina and a piece of mucous skin that will move due to the heat of the lamp is not an Ichtyobodo.

Passed the exam, earned the certificate!

The day ends with a digital exam. Everyone succeeds and you can still say that you have earned the certificate. The day ends, but the course curriculum does not. During the conversation it is immediately discussed who will see each other again next time. Unfortunately I am not there, because it is in December Joop van Tol turn.

All students, Tiebo as host and Alie as helping hand: thanks for the nice day. It was more than worth the many miles and I look back on a nice weekend!
