Fish migration research in the Netherlands

This is a video collection about fish migration and eels.

Translated from the Dutch RAVON ichthyologists:

Wednesday, March 4th, 2015

On Monday March 2, the volunteer project North Sea Canal and surrounding areas started again. About 40 volunteers went off that night with their lift nets to 18 different sampling locations. In 2014 the monitoring yielded encouraging results. Then, 2,402 migratory fish were caught during three months. Will this be equaled in 2015?

The launch of the project on March 2, was encouraging. During this cold night with high winds more than 1,000 three-spined sticklebacks were caught in Pumping Station Overtoom! In Beverwijk it was 50 three-spined sticklebacks, three silver bream and a lesser pipefish. After completion of the monitoring a first small glass eel swam along! It promises to be an interesting year. Volunteers in the coming period will monitor twice weekly after sunset. The purpose of this monitoring is to gain more insight into the migration of migratory fish to the North Sea.

Cauliflower mushrooms, not anti-dog poison

This video says about itself:

We find a Cauliflower mushroom ! (Sparassis crispa)

18 September 2014

My son was raised in the forests helping wild-craft edible mushrooms. Every year we find at least one Cauliflower – the first ending up in a bread casserole with chanterelles.

Translated from NOS TV in the Netherlands (they put the wrong photo with their new item; not of a cauliflower fungus, but of a coral fungus):

Baked sponges in Huizen turn out to be cauliflower mushrooms

Today, 11:33

The suspect sponges that were recently found among bushes in Huizen turn out to be actually fungi. That is the conclusion of investigations by the police and the Forestry Commission.

The finder guessed that they were baked sponges and that they were intended to kill dogs.

According to the Forestry Commission in Huizen, these are innocent fungi which normally grow deep in the forest. They are harmless to dogs because the animals do not like eating the fungi. …

The past few days came from different towns alerts about baked sponges supposedly deposited by people who hate dogs.

The sponges are baked in fat and smell good for dogs and cats. But once inside the stomachs of the animals they will expand and they can be lethal.

Except in Huizen sponges were also found in Almere, Hengelo, The Hague, Leiden and Saendelft. It is still unclear whether the sponges in these other places will also prove to be cauliflower mushrooms.

Mice in the Netherlands, new research

This video is about yellow-necked mice.

Translated from the Dutch Mammal Society:

Tuesday, March 3rd, 2015

For years the yellow-necked mouse in the Netherlands was only known from the extreme southeast of Limburg province. Since 2005 from the German border they are expanding to the west. Meanwhile, the species is known from all our provinces bordering on Germany. The question now is: are yellow-necked mice taking over, or may they occur in the same habitats together with common wood mice?

In Northwest Europe two species of wood mice live, common wood mice and yellow-necked mice. The yellow-necked mouse is clearly larger, but in terms of food spectrum it is virtually identical to the ordinary wood mouse.

So far, research has not yet established clearly whether yellow-necked mice supplant wood mice.
