{ Week 9 } What Fish to Harvest

  • Barramundi
  • Perch
  • Sleepy Cod
  • Perch
  • Parrotfish
Australian natives work well in this system. If all fish were growing at different rates, we can fit more in and harvest continuously. 

I can probably hold 1000-2000 fish from my current calculations. It isn't a lot but I think it will still be so much better than what would be available. 

{ Week 9 } What Food To Produce

Decisions of What to Produce Are Dependant on:

1. Cultural Dietary Requirements
2. How long we stay there for.
3. How long it takes to get there.
3. Little refrigeration requirements for storage.
4. Keep long enough for loading and distribution
5. Speed of growth for rotation of crops.

Crops that could be used include:

Beans: 4 weeks
Radishes: 3 weeks
Lettuce: 4 weeks
Spinach: 4 weeks
Onions: 4 weeks
Leafy Asian Greens: 4-6 weeks
Wombok: 7 weeks
Carrots: 6-10weeks
Potato: 12 weeks to 20 weeks depending on variety.

I think Chau can plant slower growing plants because of the size of her ship. Mine would work better with faster growing crops that can provide quick and constant turnover.

Keep in mind that these will grow faster in an aquaponics/ETFE environment because it's such a healthy system.

{ Week 9 } Feeding Fish Option: Worm Farm


Thinking about managing food waste from crew. Worms can eat food scraps, reducing waste, which can then feed the fish.

{ Week 9 } Feeding Fish Option: Fish Pellets

Fish Pellets

Probably the easiest and most realistic option.


There are formulas that can be used to calculate exactly how much food to give your fish per day.  The formulas are grams of food per grams of fish weight.  To exercise the formula correctly requires that a number of fish be caught and weighed on a regular basis, establish an average fish weight, then  calculate the correct amount to feed.


Possible to purchase an auto fish feeder device to give a regulated amount of feed per day.

{ Week 9 } Feeding Fish Option: Grow Black Soldier Fly Larvae

With Murray Hallam

Yum! Not. 

High Capacity production.

5-8 day life. They consume vegetables. Can recycle food scraps from people's meals to reduce waste. They are clean. Can be frozen but I don't want to have to freeze too much stuff. I want to keep energy use down.

{ Week 9 } Model Ideas


Exploring!!!

{ Week 9 } Other Forms


This is the montenegro apartments by BIG. Makes me think about the possibilities of organic curves.

{ Week 9 } Steps Ideas

Did some modelling. Still Thinking about form.


Thinking about how to step the "paddies" and the relationship it has with the accommodation spaces underneath.

{ Week 9 } Arrangements


Stepped Rice Paddy Form Presents opportunities of light.


Then thought about vertical planting as well.


I want spaces to work hard. Plants will need light but so will people. Accommodation will sit directly under food production spaces so that people can still have light and sir. The window will hence also open out onto the planting and have "ocean" views.


Walking areas and Semi-Private Spaces can extend beyond the food production area to create healthy vibrant spaces for people to walk, talk, relax, eat, read, work, etc.

{ Week 9 } Initial Form


Section


Alternative Form and Idea

I imagined that the structure would look like a leaf or something close to a ship for mobility but I noticed Chau is doing something similar. I am considering changing the shape of the shell. I think it will be nice if all three of us showed very different designs. So back to the drawing board. Should be ok.

{ Week 8 } Cont. Opposite Thoughts


Sinking Ship!
What if I sink the gardens into the boat. What opportunities would present itself? How about the idea of capturing wind energy and collecting water that exists in the air already? Will see.

{ Week 8 } Initial Thoughts

In section. Folding Shell.

Form
Should be aerodynamic for movement

Wind Advantage
Form should catch the wind to convert into electricity for: lighting, communications, etc.

Rising Heat
Can be captured for electricity


Form
Core as a community space. Edges as personal spaces.


Alternative Arrangements
Creating sun opportunities. Lowers energy cost. Not sure if the air to spaces ratio is good enough?


Open End
How about creating a closer relationship between the community space to the water, situating it between the water and the land. Like a beach???? There are notions about how we would normally plan a city.

{ Week 8 } Rice Intensification and Process


Australia boasts the most efficient rice production system in the world. We create the highest yields of medium grain rice, using least amount of water (50% less). I did get this information from Sunrice though.

Another efficient rice method is SRI - system of rice intensification. Currently, we are teaching women and men in developing countries to use this method to increase yields. It is a dry method as opposed to the wet one.

{ Week 8 } Aquaponics Ratios

Pilot Commercial Aquaponics at Challenger Institute of Technology (Fremantle, WA)

Say a 5000L tank will require:
- a vortex filter system
- 1000L sump tank with submersible pump
- 16 x 6m NFT channel

Shade cloth for:
- wind
- frost
- birds

Fish Ratio
- 350 Rainbow Trout
- 35kg per cubic metre

Hallam's Aquaponics

This system uses 1 Fish : 10L water : 10 L Food  (As long as fish are growing at different rates).
So 100 Fish: 1000L of water : 1000L of food can be produced.

In another video showing a commercial crop, 1000 Lettuce can be harvested every week with 4000 Lettuce growing. To achieve this rotation, it takes 2hrs a day to harvest but I couldn't find out how many people this required.

Other Systems
I also found another ratio: 1 Million Pounds of Food, 3 acres, 10000 Fish, 500 compost

{ Week 8 } Main Components

http://aquaponicssystemplans.com/wp-content/uploads/2011/07/Commercial-Aquaponics.jpg
  • Fish tank
  • Grow beds
  • Water pump
  • Aeration pump
  • Biofiltration
  • Mechanical Filtration
  • Plumbing for irrigation and drainage
  • For media based systems, medium is needed.
  • Fish and plants (seeds)
  • Water

{ Week 8 } How Plants Receive Nutrients from Fish


My dad started a small patch of tomatoes a couple of years back using a similar technique to the video. Very primitive but similar ideas of using the tank of fish at the bottom as opposed to NFT which uses a nutrient film flowing into channels. Wish I had looked more closely at what he was doing at the time...

Information below by Dr Wilson Lennard, Phd Applied Biology, Australia, studies aquaponics
http://www.ecofilms.com.au/2011/01/08/dr-wilson-lennard-on-commercial-aquaponics/


Natural Provider of Nutrients
Phosphorous, Nitrogen and Micro-minerals are provided by the fish waste as opposed to using Seasol or other fertiliser.

Additions
This system has iron deficiencies so you need to add this especially in the first year.
Calcium hydroxide and Potassium carbonate is also added. This also balances pH.
Sodium bicarbonate is a cheap option but sodium is not good for the system.

{ Week 8 } Hydro/Aqua-ponics Research



Benefits of hydroponics.

  • No soil is needed
  • The water stays in the system and can be reused - thus, lower water costs
  • It is possible to control the nutrition levels in their entirety - thus, lower nutrition costs
  • No nutrition pollution is released into the environment because of the controlled system
  • Stable and high yields
  • Pests and diseases are easier to get rid of than in soil because of the container's mobility
Benefits of Aquaponics
  • Yields 25-75% Faster

{ Week 8 } Circle of life

Mimic natures cycles.

Produce an ecosystem?

For example, produce seaweed for consumption and use as fish food to harvest fish. Fish waste can be reused for seaweed production.

But what about plankton and other things you can't get? Maybe it should be open for any fish to come along

This is hard. Time to look at food production soon

{ Week 8 } Ship Basics

SHIPWEIGHT 9 with crack !!!

When designing and building a vessel, weight and center of gravity are key parameters for successful performance. Speed, strength, deadweight, stability and seakeeping are all parameters crucially dependent on the weight and center of gravity. To ensure and maintain these parameters a reliable estimation of weight and center of gravity followed by an organized tracking and monitoring activity is essential.

{ Week 7 } Inspiring Ship Engineering: Catamarans

Benefits of a double hull
Faster than monohulls as there is less drag in the water.
Resists overturning better

Cons
Slower to turn than monohulls due to drag
Can capsize
