               Step 4

What equipment is needed for fish farming?

  • Pumps;

They ensure the fish have adequate fresh water by filling the ponds, or tanks with fresh water from the source.

They also came in handy when you choose to drain the ponds at the end of the growing cycle. The two common types of pumps used are the centrifuge and turbine pumps.

The centrifuge pumps are set horizontally and the turbine pumps vertically.

  • Aeration devices;

The main task of the aeration devices is to ensure adequate supply of oxygen to the fish. They allow you to have more fish in a small space.

Fish farmers with the use of recirculating aquaculture systems (RAS), can now keep fish in tanks housed in building basements.

They also make recycling water after removing impurities much easier.

  • Nets/ Seine Reels;

After the awaiting the growth and maturation of the fish and it is time to harvest the seine reels or nets are effective.

Seine sinks to the bottom of the pond or tank and with assistance the reel gathers the fish towards the outer edges of the seine. By doing so the fish gather into the nets.

During this process ensure the aerators are on full speed as the fish are in close proximity to each other requiring maximum oxygen supply.

  • Handling and Grading Equipment

While fish harvesting, you grade them by size. The grading process is important as it ensures improvement in growth of the fish.

Poor grading will make the smallest fish have difficulty in gaining access to food because of competition with the larger fish.

There are two types of grading equipment;

i.   Mechanical graders
ii.  Manual graders
iii. Fish counters

The last step and the most important to address is feeding.

Demand feeders are used for particular species of fish. The tilapia is fed in small quantities over a period of time.

Clockwork driven belt feeders are used for the smaller fish species. It is an equipped belt that rolls on a clockwise motion. The feed is placed on the belt and it is rolled up progressively over 8-10 hours releasing the feeds slowly.

Manual feeding is commonly used, you should train to feed them according to their behavior.

Calculation of daily feeds should be based on weight, water temperatures and water quality. When feeding the fish consider their behavior, appetite and aggressiveness.
