Title: Some bass myths settled and Questions answered.
Post by: rayke1938 on March 01, 2012, 07:52:45 PM

I am reproducing this with permission from Dinodadog as he is unable to copy and paste.
He has been attempting to get an authoritative answer to the question asking if bass change sex when they get older.
The hatchery manual for the breeding of Australian bass is a very interesting read but be warned it is 49 pages long and too large to copy to the forum so you will have to click on the link.
 I know that is is old hat to the likes of Kurt and others but I personally found it very informative and maybe it will give others a better understanding of the subject.
If you wish to delve deeper have a look at the other species mentioned also.
Cheers

Hi Dennis

Thank you for your enquiry about bass.  There are several species of fish that do change sex as they grow older, however, bass is not one of them.  I have checked this with our Research Scientist; Dr Stewart Fielder who leads the Marine Fish team here at the Port Stephens Fisheries Institute.

He suggested you may be interested in the biology section of the Hatchery Manual for the production of Australian bass, Mulloway and Yellowtail Kingfish.  Here is the link to the manual:  http://www.dpi.nsw.gov.au/fisheries/aquaculture/publications/species-saltwater/hatchery-manual (http://www.dpi.nsw.gov.au/fisheries/aquaculture/publications/species-saltwater/hatchery-manual)

Please don't hesitate to contact me if you would like any further information.

Bye for now

No myth that Bass are dioecious Ray a simple google search will tell you.
As to adaptive sex change in confined populations of single sex dioecious fish which was the subject of the discussion which started this  :popcorn)
