New Born Album

New Born Album

Postby Luis A M » Sun May 06, 2007 3:50 pm

I thought it would be useful to start a library of new born fish and shrimp.Only newly hatched larvae,or newly delivered fry,in the case of Banggais and Seahorses,should be pictured here.
Accurate measurement is important.Either total length (TL) or standard length (SL),when the caudal fin of a larval fish can not be seen clearly.
Knowing if a larval fish is hatched with a yolk sac,and it's size,will help to design a good rearing protocol.
For those not having precise built in measurement optics in their microscopes,following method is good enough. Take a picture of a mm ruler under the same magnification you used for the larval pic.Camera setting,such as zoom,must be exactly the same,as well as processing of the pictures until they are posted.You can also post the ruler so everybody can take their own measures of your picture.
This will be my ruler:
ruler.JPG





Measuring this pic in my computer's screen,6mm measure 15cm.
6./.15=0.4,which is my correcting factor.Then I can measure on the screen and make the cm times 0.4 and get the result in mm.Of course the correcting factor will be different in each computer.

Sweet!
When I have larvae again, I'll have to try this.

Got to go sell some fish! I need an empty tank.....

Luis, this is a good idea...perhaps in the future we can expand upon it (i.e. maybe down the line we'll be able to have galleries that people can contribute and upload to etc...)

For now, folks, tag on your larval pix to Luis's thread....

Forgot to mention that the greenish stuff inside is yolk material,the equivalent of yolk sac in fish.
Otherwise the larva is completely clear,the gut can be seen running along the whole body.So it is easy to tell apart newly hatched larvae of L.amboinesis,L.debelius or the peppermints.

But only newly hatched,please! :D This is a "new born only"album.
Older larvae should be placed in other thread here,or perhaps posted in their species forum?
And we should stick it?.Guess a thread can be sticked only when started?

Right Kathy! 8)
Checking in my 17"office´s monitor,6mm measure 19cm,so the correcting factor comes to 0.3.

Glad you guys are posting!.It looked as my personal album! :(
Kathy,sure your baby is cute,and we´ll let him join the party,but this is meant for newly hatched,measured larvae :)
Of course we can make a general larval gallery or something.
But in the particular case of pelagic prolarvae,I think we should register both how they look right after hatching and also when they become real larvae.
