Coming to realize, the last series of cubes for

creating a hollow space from the ocean floor...

 

On shallower surfaces, it can be used as a

marine life preservation site.

 

The cubes will need to be modded a bit,

with see-through glass, and ways to

separate the eggs when it reaches the bottom,

by a suction system once filtered and

protected from the other fish.

 

But that would create plenty of space,

and.... less maintenance in the longrun... possibly.

 

That is of course, on shallower waters.

 

 

And if to create automated fishing ships in a very cheap way.

Drone ships. But not by metal.

 

As i've suggested before, interlocking many long beams

of wood together with glue, and bind them together

to create a giant rectangle.

 

And with a handheld router, subtract the mass

in any shape and arrangement.

 

Only the outer surface will be plated with thin

sheets of aluminum, to prevent the water from

contact with the crevices of the wood, which has glue.

There are sealants of course, but to make it lasting,

aluminum sheets, screw-on, and weld the gaps to finalize.

 

By far the fastest way to build biggest ships

in cost-effective way.

 

The mast can be foldable, sails can retract and fold itself

with gears.

 

Path of the ship can be changed with very primitive way

of turning, such as the mechanism used in polynesian cultures,

a beam, with a common vertex (line) but one surface is

in an angle, so it creates friction with the water,

turning the ship when the beam is dropped down.

Automation is possible with use of gears as well.

 

Then, robotic arm. Radar, metal cage. Release into the boat,

with certain compartments ready for their sustenance.

 

The energy required for folding/movements of these gears

can be charged by a power generating turbine.

 

Movement by sail, but I don't think motors are required.

If thinking longterm, and aiming specific goals.

 

It can be used with starlink, complete drone ship.

But completely cost-effective to build...

 

But just a concept. Some species will require monitoring by

humans, while others may not....
