Lunch Time!

The salmon used to feed off their egg sacks, but now they are eating off the food we give them. Since they are eating they have grown to be about 1 inch long, with parr marks all over them. Their food has also made them stronger so that they can swim to the top of the water to retrieve their lunch. Their  stomach is getting bigger and they have a thin glossy layer over their scales.        

Tiny the Salmon

Tiny the Salmon

Tiny is the smallest of all the salmon. Tiny is just the same as any other salmon, the only difference is that... well his name describes it! He is the tiniest! Possibly he is a runt so that is why he is so small. He must not have many friends because every time we look at him he is swimming alone. Tiny seems to swim the slowest, maybe he has no friends because they don't see him because he is so small. I hope that Tiny has a better life when he's older, we know that we will not see him then. 

Interesting Hand Movments

The Waving Of the Hand 

  The salmon are growing by the second, it's awesome to see them progress so fast. One really cool thing that we noticed is that when you walk up to the tank and you start waving your hands around the salmon scatter. This does not usually surprise people but what surprised us was how you do it. If you do it crazily and you run up to the tank and jump around like a monkey waving your hands around they speed away like rockets. If you do it calmly and wave slowly they react the same way swimming away slowly. The different things that we learn about the salmon is intriguing and we can't wait to learn more.    

Way too Much Food

Way too Much Food

    Today in the morning there was a horrible tragedy that there was way too much food in the salmon's tank. Imagine, a huge light brown  blob of food in the middle of the tank with fish swimming all around it, which killed one of the poor little salmon.  We think it was a mixture of dirty water and eating too much food that killed the salmon. For some reason, someone put too much food in their tank. Luckily the kids were able to clean the tank before it harmed any other salmon.

COHO SALMON LIFE CYCLE

The coho salmon life cycle starts when the salmon are eggs. In about a few weeks the salmon start to hatch one by one. The salmon life cycle takes a while. STAGE ONE: The coho salmon are eggs,and later we saw them in their eggs and watched them wiggle and move side to side. STAGE TWO: They hatch with their yolk sac to feed on for the next few weeks. STAGE THREE: There yolk sacs disappeared and when the yolk sac disappeared one that had two heads died. STAGE FOUR: When we got back from winter break they had changed colors and they have stripes on their back they change colors because the light  reflects off the glass on the tank. STAGE FIVE: this stage is about the coho salmon now 1/28/15 they look like actual full grown salmon but very little.

                                                                      Salmon Stripes

                                    When we arrived at school after Winter break we were in for a big surprise! The salmon grew up! Most of them have lost their egg sacs. They look like they have zebra print on them, but not with the same colors.There are streaks of black and small dots on their body and their bodies are silver.These lines and dots covering their side are called Parr Marks. The salmon's Parr Marks help camouflage them. You can faintly see their fins. They've been swimming up to the top and sometimes they look like their climbing up the sides. Their growing up so fast!

NO FINS

There is a fish in the tank with no fins. The no fin fish tries to swim around like the others ,but just swims in circles. He doesn't have control over his swimming. He keeps swimming awkwardly. The no fin fish doesn't swim  to the top right now he is probably thinking'  ¨no fair you swim better than me.¨'He does flips and swims on his sides. Maybe he will grow out his fins someday.
