Octopus 4 Lunch- Kardamina, Koz, Greece

One day the ARC will serve fresh farmed Octopus! Just like Mama!!!

How MUCH Water is in that Aquarium?

Students will need to collect data-
Height, Length and Width of Aquariums in the ARC to then apply a formula to determine the volume of water each is capable of carrying.

This is vital in:

• adding salt to make the water suitable for marine/salt water species
• determining water flow and aeration
• applying chemicals for illness

AND

• total biomass verses water volume to calculate the number and size of fish each aquarium can support.

Bubbles of Brine

Bubble, bubble toil and ... trouble! Brine Shrimp (Artemia) cycts added, air stone active, bubbles active- some cysts are stranded on the side of the container by the action of the bubbles. They will probably perish as the salt water would have triggered hatching and then left 'high & dry'!!!

A Home For Brine Shrimp

All set and ready to go. Just add salt water and brine shrimp cysts!

We still had issues with leakage through the tube/lid connection and needed to re-silicon the lid hole.

The Daily Grind

The Daily Grind

Yep, it's life on a farm- 'early to rise... early to bed'!

Everyday

• Open door to ARC to enable sun on seedlings/air flow
• Feed peas to Yabbies- not too much not too little
• remove rotting food from aquarium
• Feed pellets to Silver Perch *Tank 6 (stored in plastic container on metal shelf)
• Feed lettuce to snail (lettuce from Canteen, stored in fridge
• Feed lettuce to worms
• check all water levels
• check water quality
• water garden plots
• weed
• water seedling in ARC
• ensure tap key is always returned to ARC
• ensure ARC is always locked ALWAYS!
• all tools returned to ARC- check for damage. NO DAMAGED TOOLS ARE TO BE USED
• no food scraps in ARC, deter rats, mice and cockroaches
• sweep ARC
• collect rubbish, especially rocks etc. from farm and ARC, move to school bins

• Tuesday- 3 * opaque water Jerry cans to PDHPE staffroom to be filled with sea water by beach sport
• Wednesday collect sea water from PDHPE, syphon appropriate litres of water from marine aquarium/s- just enough to enable water exchange to return water level to appropriate level

Jobs completed @ the ARC

• moved female Yabbie (new mother) from nursery aquarium back to communal tank. Babies doing well (100's)
• moved female in 'berry' from communal tank to a new nursery aquarium
• setup, YET another aquarium for more berried females. Set water heater to approx. 23C
• fed all aquarium/tanks- peas
• water tested Brine Shrimp (Artemia/Sea Monkey) nursery bottles- all needed silicon to prevent leakage. Siliconed and awaiting drying.

*Will add Brine Shrimp either Friday or next week.
