I have had a few requests for for this...so here it is so far. The image is of Alantic Salmon eggs prior to hatching. The eggs are about 480 degree days old.

~This is an Alevin just hatched from it's egg. The Alevins surrive on their sac for about another 300 degree days before they start to feed.

The Alevin here is about half way through its growth before first feeding. As you can see the sac is starting to reduce and the body is changing. Notice the fins are starting to form.

This the same batch of fish, now fry, about 6 weeks after first feeding. This was taken last week. I hope you enjoyed this small doc. I will post more over the next few months as they develop. Steve : Scotland

Get the borax.... wow this is good reportage. Are you going to do a salmon enhancement prog?

YIPPPPPPPPPEEEEEEEEE!!!!!!!!!!! Spinning in my chair over here, Steve!!!!!!!!! OMG, i ADORE these pictures!!!!!! #2 is my fav!!!!!! you show his little mouth and eye so clearly!!!!!! oh wow...seeing the development is so incredible!!!!!!!!!!! oh man i'm so sorry i eat salmon now. ;( oh...in #3 i notice his little fin!!!!!!!!! adorable!!! and in #4, look at that top guy...he looks a bit scared or lost! awwwww. you gonna post any of these in your gallery??????? i sure hope so!!! maybe you already did??? running there now!!!!! THANK YOU THANK YOU THANK YOU!!!!!!!! :)

Cool, interesting seeing this. Never knew about the sack.

Oooooh! Very cool!!! Thx so much for sharing this!!! Fascinating and adorable!! And yes, Sheila, I'm wondering how u can eat those 'lil creatures, u awful woman! :P

Thanks for the comments. OH dear... Shelia is now going to feel guilty when someone orders salmon now....... These shots are not easy to take with a non-DSLR camera in macro mode. Manual Focusing is the main problem through an electronic eye piece. Mmmm might put #4 up for the caption thingy. Steve

good idea! feeling a bit guilty too as i luv salmon! yummy :d

Awwwww! :( U guys are barbaric!! I hope the guilt will turn u vegetarians! ;P

Slap it on the BQ.........

wow, interesting stuff!! Not wanting to seem thick, but what's the difference between a degree day and a standard 24 hour one?!? Is the degree one better educated or summik? lol ;-) (",)

LOL@Mike!! Good question actually! I was wondering the same thing!

I knew we were all wondering it but no-one wanted to appear ignorant enough to ask...... as the resident Psycho Troll ignorance is part of my job description. ;-) (",)

I was waiting for someone to ask. A degree is the average water temp for the day. Therefore if the water is 6 degrees, that is a 6 degree day. So therefore you keep a record of the daily temp and accumulate it. Hence 1000 deg days at a water temp of 10 deg C equals 100 normal days. Hope that helps. Eggs and Alevins are kept at approx 6 degree and fry (pic #4)at approx 12 deg. Steve

A bit more info, the alevins at first feeding are about 0.18 to .2 grams per fish, and the fry in pic 4 are about 0.8 grams and about 32 mm in the length.

Ok! Thx for the Chinese Steve! O_o It's SO much clearer now!! LOL!

Glad I made it so clear..........Mmmmmmmmmmmm Steve

So, lemme get this right - unless you know the water temperature, you can't tell how old they are? Like, in the first one they are 480 degree days old. As we don't know the water temp they could be 48 days (@10 degrees) or 80 days old (@6 degrees).....? And what happens if the temp changes, like for half the time it's 8 degress? that would make them 70 days old.... ehhh? Blimey, the Gregorian calender DOES have it's advantages ;-0 Wow. poor things. imagine not knowing when your birthday is coz it got warmer........ (",)

The water is logged automatically via a data logger. Then the temp is averaged for that day. So yes you are right, the old Gregorain calender does have it's advantages... :) At certain stages of lives it is very important that the temp remains in a certain temp band, i.e. when there in their egg and Alevin stage, the temp should remain about 6 degrees (C).
