Why Phosphating is detrimental on a Chromated cold rolled material?

Phosphated cold rolled sheets are usually given a chromic acid sealing to improve their corrosion resistance. Why the reverse can't be done? Can chromated sheets be powder coated without phosphating?

Does anyone have an insight into the behavioural response of fishes to moving wind turbine blades as seen through the air-water interface?

I am interested to find out if wind turbines located close to rivers or lakes, or perhaps even in marine locations, are a potential problem for fish. This seems to be a very under-researched area...

Ton van Haaren

looks very much like Cyathura carinata we have here (Netherlands), but not sure if there are siblings in Italy. I have added a photo of a Dutch specimen

Michael L. Zettler

It is an Anthuroidea species for sure. The estuarine character of your sampling location indicated the possibiloty of Cyathura carinata, but it can also be another species.

Please check Wägele (1981) Study of the Anthuridae (Crustacea: Isopoda: Anthuridae) from the Mediterranean and the Red Sea. Israel Journal of Zoology 30: 113-159

With a better picture of the telson, I think we can be 99% sure of the species identity. In the Scheldt estuary, we also have C. carinata and it also dwells in the oligohaline and freshwater reaches of the river.

Succes with the identification!
