  • Dispenser: Part of the feeder that distributes the feed.
  • Hopper: Part of the feeder that holds feed before dispensing.

Classification of Feeders

  • Automatic Feeder: Automatically dispenses feed at a pre-determined rate and schedule. Uses mechanical mechanisms (alternating movements, rotations, or vibrations) or compressed air.
  • Demand Feeder: Feed discharge operates based on fish appetite. A trigger mechanism activates feed dispensing when the fish interacts with the feeder.

Hopper Capacity

  • Amount of feed that the hopper can hold.

Fabrication Requirements

  • The feeder hopper must have a lid or cover.
  • Supporting frame needs to support the entire feeder during operation.
  • Bolts, nuts, screws, bearings, bushings, and seals must follow PAES or international standards.

Performance Requirements

  • Discharge rate must meet the manufacturer's specifications.
  • Discharge rate variation should not exceed 10%

Safety, Workmanship, and Finish

  • Free from manufacturing defects that could affect operation.
  • Base or frame must be rigid and durable, without visible cracks or weak points.
  • Metal surfaces must be free from rust.
  • Emergency stop mechanism must be included.
  • No sharp edges or rough surfaces that could injure the operator. Warning notices as per PAES 101:2000.

Warranty

  • Normal wear and tear parts are not covered, except for at least 1 year of normal maintenance and parts.
  • Follows requirements in PNS/BAFS/PAES 192:2016 for specifics.

Maintenance and Operation

  • Manufacturers' tools are provided for maintenance.
  • Operators' manual containing maintenance schedule and list of warrantable parts is required (based on PAES 102:2000).
  • Feeder must be easily operated, maintained, and repaired.

Sampling

  • Follows PAES 103:2000, or other suitable method, for testing the feeder.

Marking and Labeling

  • Each feeder unit displays manufacturer's information, such as registered trademark, brand, model, year of manufacture, serial number, manufacturer's contact details, country of origin/made in Philippines, feed hopper capacity, discharge rate, power requirement.
  • Safety and precaution markings are displayed. Markings must be durably bonded, resistant to all weather types, and legible.

Testing

  • Testing conforms to PNS/BAFS PABES 288:2019
