2So What is Aquaculture?
- Aquaculture is growing plants or animals in salt,
fresh or brackish water, It has been practiced
with Hawaiian islanders and the Polynesians over
1000 years ago. Basically aquaculture is the
science of fish farming.
Open ocean aquaculture is like a farm in the
ocean. Like the image seen below, only a few
operate around the Hawaiian Islands.
Aquaculture is the logical choice to preserve
marine life.
3Why Is It So Important We Have Aquaculture In
Hawaii?
The ancient Hawaiian Islanders made and
farmed only what was essential to survive, but
now, due to the high demand from consumers, the
fish population has been decreasing. Over 50
million pounds of fish are eaten annually by
Hawaii alone.
Its important that we restore more of
the fish population before most fish species
become rare or even extinct.
Hawaii has a perfect climate for aquaculture
locations, so we should use that as an advantage.

5 Did You Know?
Interesting Facts About Aquaculture
-Back in Ancient Hawaii they had fishponds called
makaha
-Fish ponds, unlike the ocean, are controlled
environments and are almost completely man-made.
What goes in and what comes out can be completely
controlled and monitored. So the fish farmed
there are free of pollutants.
-The fish in those fishponds can also be fed a
lot more than what they could manage to get in
the ocean, and thus this would generally result
in better fish harvests.
-For ancient Hawaii fishponds were used as the
the focal point for the ritual and supernatural
forces that were vital to ancient life.
6Life Without Aquaculture
Without fish farms and aquaculture, fish species
will become endangered and in worse cases extinct.
Fish population would be decreasing tremendously
over time and fishermen and commercial fishers
who live their life catching and selling fish
wouldnt be very successful because there would
be less fish in the ocean and may take a while to
catch just one fish.
Life In Hawaii Would Definitely Not Be Pono
(good).
7So What Is Over Fishing?
- Well most states in America have fishing laws,
one example of a fishing law is, you must return
the sea creature thats caught if it doesnt meet
the standards of the minimum size. - These laws are to help the fish populations to
be healthy and so no sea creatures are in risks
of being extinct. A very common law states that
you cant go over a specific quantity of fish.
8Fishing Over The Limit, Under, Fish
Population
Satisfaction
- Drastic fishing in the United States, especially
in Hawaii, has caused many species of fish to
become endangered. Because of this, there are now
laws and regulations on fishing in Hawaii and on
coastlines in the United States. These laws help
make sure fish species dont become extinct. -

9Some Fishing Laws On Oahu
In Waialua Bay it is prohibited To take any
illegal size fish in season with one line, or one
rod and line, with more than two hooks.
The Uhu or Spectacled Parrotfish, can be caught
if it is larger than twelve inches long. Anything
smaller than twelve inches is breaking the
over-fishing laws.
At Pokai Bay it is illegal to be using fishing
nets that are more then two feet in diameter.
It is strictly prohibited to take the State Fish,
the Humuhumunukunukuapuaa.
10What Is The Difference of The Hawaiian Methods of
Catching Fish Comparing To Todays?
As you see, as we progressed through life tools
became more easier to use and catch fish with.
The ancient Hawaiian islanders were very
resourceful because they would make their own
tools with the limited resources around them.
Hawaiian tools Examples -Spears made out of
wood (whatever type was indigenous of the area.)
For the tips, they used Metal, copper in
particular, was a popular tip as was bone -nets
- Modern tools
- Examples
- -Spear guns and harpoons
- -Throw nets just made out of different material.
- Fish rods
- Fish Cages
11In Conclusion
Aquaculture
Aquaculture had been in Hawaii since the Ancient
Islanders years ago and its a really efficient
to preserve marine life.
Over Fishing
Over fishing is a problem all over the world and
if continued can be a really big problem towards
the future.
- In conclusion, Hawaii needs more aquaculture
farms, and should enforce fishing laws so in the
future everything would be alright.
