Fish and Sex

[carlyai]

Bought some fishlings yesterday for my aquaponics system. 

The owner said the fish are not male or female but sexless. Also there was talk of fish that can't have babies. 

So I hear at best 3/10 Words at machine gun rate, but can't find these words in my HAAS dic.

 

The words I heard for sexless fish are like:  'kaay phan' and for can't have babies 'man'. This is in Thai . 

One of you learned gentlemen, sorry gentlepeople know the Thai words and meanings?

 

Seems fish aren't binary either. Wonder if you have fish that fit into the LGBY etc pronoun?

What species of fish are they, Tilapia , catfish,?,if they cannot

breed how did the seller get them ?

I know a tiny bit more than you. Fish are Tilapia. Seems males are better (of coarse). So they mix hormones in the water (maybe) with the fry, and that does the trick by producing mostly males. 

There again I could be completely wrong.:)

I could send the article in that direction....about the old fisherman and the huge Grouper.

You're like the other reader, saw the headline and thought/wanted something kinky.

So they have all been turned into males by a hormone process,

I hope the same does not happen to any females that eat the fish !

Some marine fish can change sex themselves, if say a group of

Clown fish are all females, the largest of them will change into a male fish.

The MAN one is probably:

MAN หมัน - sterile, barren

TAM MAN ทำหมัน - to sterilise

Apparently male tilapia grow faster than females and are preferred for farming so they add a hormone, methyl testosterone, to the water or feed of new tilapia hatchlings to reverse the sex and prevent females.
They also have ways of making them sterile by genetic manipulation to stop them spawning before reaching marketable size.
