Natural River fishes in Japanese Izu Peninsula
Hi all !
I show pictures because I took a photo underwater in the river of Japanese Izu Peninsula. last month.
Because the Kuroshio Current flows through the sea near the shore, the district is comparatively warm.
It is uploaded video clip to YouYube as always.

Hi plaalye!
The small prawn would think one's reflected image reflected in the lens surface to be a rival.
The water temperature was about 20 degrees Celsius.
I do not do the water test, but this river has a big hot spring upstream.
An ingredient of the hot spring may be what is advantageous to the breeding of the alga.
Because both eat an adhesion alga, sicyopterus goby and the sweetfish are rivals.
I heard that both did a territorial dispute frequently, but a fight was not seen at all in this river.

Hi all !
Everybody enjoys it, and I am glad.
The worst foreign fish in Japan is a large-mouth bass.
However, as well as Japan, a menace of gobies is natural destruction by the human being.

I think that the menace of Catfish does not matter much.tyrano34 wrote:Your goby fish are in danger?

Hi tyrano34!
You can confirm a lot of rivers of Izu Peninsula when you lose expansion.

I do not know parameters of the water.
I photographed the pictures mentioned above in the plural rivers of Izu Peninsula.tyrano34 wrote:could you give us information on the fishing grounds.
Would you parameters of the water?

Thank you for the card I knew or found the Izu peninsula, which I find is the name of the river or you're sunk.
Thanks for your videos on youtube, I could explore the Japanese Internet and I saw that a word that often return to the subject of gobies.

"ボウズハゼ" is Bouzu / Haze.
Bouzu means a Buddhist priest, and Haze means a goby.
The origin of the name is a meaning called the goby of the shaven head or a meaning called the goby of the vegetarianism.
"ボウズハゼ" means Sicyoputerus concretely.
"ナンヨウボウズハゼ"is Nanyou/Bouzu/Haze.
"Nanyou" means South Seas.
"ナンヨウボウズハゼ" is a meaning called Sicyoputerus of the South Seas.
However, actually it is Stiphodon percnopterygionus or the Stiphodon genus as a fish class.

yes Graeme
an interesting specimen of 7 cm, female with 5 cm (may be I've two with different colours
on a german website - with breeding infos - they are identified (with doubts) as r leavelli. I doubt it. as M. Kottelat doesn't identify rhinogobius by pics I'm stuck. more pics are on seriouslyfish.com.
seems to be a freshwater species without pelagic larves, but it seems to be hard to make them survive. I found two other pics on the web, one with the id as r sp OR (from Japan) which is certainly wrong. no way to fix the origin. south of china is the most probable as the first female came in with pseudagastromyzon cf cheni=p fasciatus, peristictus, myersi mix.
