Talk:Fish migration

Stream deflectors
an article called stream deflector should also be created. These (emphasis on triangular stream deflectors) are also often used to restore straightened streams to a more natural stream (while stil allowing good use of the still quite straight river) and allow fish migration. See http://cgrg.geog.uvic.ca/abstracts/BironAssessmentInstream.html

A picture similar to the one at page 7 from following document http://www.vmm.be/publicaties/2009/Verrekijker_FEB_09_low_TW.pdf#page=4&view=FIT should be added.

Root Derivatives under Terminology
The "-dromous" end root of each word is not defined, even though the rest of the roots are. This addition would be extremely helpful, even though its definition may be easily be deduced by someone familiar with Greek and Latin roots. —Preceding unsigned comment added by 74.235.10.224 (talk) 14:36, 3 June 2009 (UTC)

Classification section edits
As per the template which was on it, I condensed and simplified the section considerably for layperson readability. I hope my edits are appropriate and sufficient. Naturally, I invite any editors to have a look at the diff page and see what you think and/or re-edit as you see fit. JustDerek (talk) 00:21, 6 September 2013 (UTC)


 * I see no issues to remove the technical tag now. It's fully readable for laypersons who have interest into this subject. The terms may be changed in up-migrating fish, down-migrating fish or multi-migrating fish etc, however this doesn't specifically point out specific scientific understanding. Lets stay with the generally accepted terms. — Preceding unsigned comment added by 85.151.136.111 (talk) 19:44, 20 August 2016 (UTC)

Anadromous
From "Classification": "Anadromous fishes are ones which migrate from the sea into fresh water to spawn; or, ones which stay entirely in sea water and migrate upstream to spawn." How can a fish stay entirely in sea water and migrate upstream? Axl ¤  [Talk]  15:16, 30 January 2014 (UTC)

Amphidromy
I am surprised to see 'amphidromous' listed here as a word which "did not catch on". In New Zealand, this word/concept is critical for understanding a large chunk of our freshwater fish fauna. One of the families, Galaxiidae, owes its broad distribution spanning the Southern Hemisphere to amphidromy. Google search results, on Scholar and normal google, indicate that the term 'amphidromy' is used more often than 'catadromy', although 'anadromy' is several times more commonly used than either. Unfortunately I can't access the citation for this: "Lexicon of life cycle diversity in diadromous and other fishes." StellaMcQ (talk) 04:20, 18 August 2015 (UTC)
