Pacu Farm

Pacu are represented by 3 species, and differ in breeding temperature:
 * Gulp Fish -30...+5°C
 * Pacu +5...+35°C
 * Tropical Pacu +35...+80°C

On the merits of the largemouth - cleansing and cooling polluted water was discussed here. Tropical Pacu - gives +25 decor (5 cells). Otherwise their content and utility is the same, and we don't care which species will prevail.

The output of the scheme is fillets (fried +3 morale), kilos of shell (you can't have too much steel), and land. The scheme is simple, the costs are paltry (some algae and electricity).

Properties of Pacu

 * Feed: algae, 140 kg/cycle
 * Excretes: polluted dirt, 50% of what is eaten
 * Life span: 25 cycles
 * Reproduction rate: 7% (no care), 67% (happy)
 * Incubation rate: 20% (basic)
 * Room size: 8 cells/animal
 * Survival temperature: -50...+100°C (depends on species)

Description
The farm consists of 2 parts:
 * Left, hungry, in which the pacu are kept in cramped quarters and without feeding
 * Right, half-starved, which connects to the pool (artificial or the first available), at the rate of 8 cells of liquid per fish, and with partial feeding.

It remains to dig a pool or use a suitable puddle:

If you feed Pacu as it should be, for example, it would take almost 3 tons of algae per cycle for 20 Pacu, which is a lot.

That's why the critter feeder is set to a minimum of 1 kg, and the right auto-sweeper loading the feed into it is activated by a timer for 20% of the time.

Settings

 * Feeder - 1kg.
 * Cycle Sensor - 10% (set it higher at the stage of domestication and 0% to stop the litter)
 * Conveyor Loader: top - eggs, bottom - everything except eggs and algae.
 * Number of paсu in the right pool - depends on the volume (per 1 pacu 8 liquid cells). Accordingly - animal sensor settings.
 * In the left (hungry pool) - not limited (it can be 5, and 100, and 10000pcs).
 * Conveyor Rail - top, feeding algae; bottom - unloading shells, earth.
 * Any liquid (mix works compactly: 50 kg/cage - water, dirty water, petroleum, crude oil, etc.). In the uppermost cage from 400kg.

Productivity


The right-hand pool was 20 Pacu in volume (the pool had about 50 kg/cell of polluted water, crude oil, petroleum, salt water, and the last few cells of water. The circuit has ramped up to 170 Pacu.

In 1 cycle, the circuit consumes only 35 kg of algae, and produces:
 * kcal fillets (10800 as fried fish)
 * kg of shells
 * kg of polluted dirt (with 35 kg of algae, polluted dirt should be about 17 kg, why less - do not know, double-checked 3 times)

So, without any labor, the farm is able to feed a colony of 10 doubles, with minimal algae and power (about 16W).
