Check out Florence IN the finfish tank
Aquaculture Report 2/5/2011 by Florence Bloomfield
Today in Aquaculture instead of breaking in our regular routine, we got together as a group and discuss possible ways of going about and change the screen on the center drain of the Fin-Fish tank. While discussing we came up many ways of going about and completing this job, but doing so we might lose some fishes.
We came to a conclusion of having one of our students go inside the tank and unscrew the screen on the center drain. By doing this we had to drain the water from the tank. Draining the water from the tank the fishes will lose oxygen really fast, so we had to work fast and efficiently. Starting off we transferred the water from the Fin-fish tank and distributed the water to different perimeters of our lab.
With the help of everyone working efficiently it was a success transferring the water and doing it at a fast pace because the fishes were losing oxygen. After the transfer, I was the lucky student who got to go inside the Fin-fish fish tank and unscrew the screen form the center drain. I was excited to do this, but with the fishes wanting to jump out the tank because of little oxygen made me a little scared, but unscrewing the screws from the screen on the center drain was a success because all the fishes survived. With the help of everyone everything went well. We then transferred the water that we removed from the Fin-Fish tank back into the tank and got the system up and running again.

This is a picture of Pete’s Dad and the group that visited Fishers Island. In this picture, it shows Pete’s Dad explaining how to add algae to conical filled with oyster algae. He is also explaining the amount of larvae each conical recieves. I learned about how to measure out the algae to put in the conical and also how it would look after a couple hours of the oysters eating the algae, “crystal clear”
Alpha uses a hand counter to count the number of oysters in 1mL. We use this number to calculate how many oysters are in 30 Liters. This allowed us to count 6.1 million oysters in 10 minutes.
This picture shows Alimot, Hanaa, Alpha and Victor. Alimot is looking into the microscope to see the oyster larvae moving around on the glass slide. We were getting to count the amount of oyster larvae on the slide. We can use this skill in our lab when we start growing our own oysters
Final Project for 2nd Semester.
Aquaculture Report-1.19.11. By Hanaa Butcher
For our Final Projects, each group have to draw a detailed picture about their systems. For the Xr-3 system, Todtiyana Bown, Alimot Yussef, Florence Bloomfield and I would be drawing out the tanks, biofilter and the many pipes. Discussing how the water travels throughout the system. For the Finfish, we have Alfonso Gonzales, Victor Traveres, Mike Jones and Najah Louree. They would be discussing how the water is traveled from the finfish tank, to the bubblebead,then to the UV filter into the biofilter, into the heat exchanger into the cooling unit and back into the finfish tank. These series of steps would be drawn out onto poster paper and would have detail descriptions. For the Aquaponics, you have Jennifer Mendez and Candice Reyes. They would be disscussing what makes up their system and how using the finfish water, their tomato and basil plants thrive. The final system is Special Project and Holding System who has Venessa Ero, Millie Olivo, and Devin Mojica. They would be discussing the oysters and how they converted their entire system from fresh water into salt water to accomidate the oysters.
Special Report: “Ladybugs” by Candice Reyes
Ladybugs were added on Friday, 1/14/11 to the aquaponic racks, to kill off the aphids eating the plants. The lady bugs were a great addition to the plants. Right now the ladybugs are mating, making new ladybugs to keep any problems from happening again.

Special Report
Stocking Density vs Growth Rate by Todtiyana Bowen
The advanced aquaculture students Alimot, Hanaa, Florence and me created a stocking density experiment which consisted of fish tanks water food and a triple beam balance. The project went on for 4 weeks and we used our XR-3 system. We had 20 tanks we slipt the fish up into four different groups. Group one had two in each of four tanks. Group two had four fish in each of four tanks. Group 3 had eight fish in each of four tanks. Group four head 16 fish in each of four tanks. We initially weighed the fish and fed them 10% of their initial weight. We weighed fish once a week and changed their food amounts accordingly. This process of weighing fish and weighing food continued for about a month. We came to the conclusion that fish grow at a faster rate with a lower stocking density. This is relevant to fish farming because when growing fish it is better to have less fish in more tanks than more fish in less tanks. This will allow you to sell fish at a faster rate and raise fish at a faster rate. If your fish grow at a faster rate you can sell more!
