Study Notes

Philippine National Standard for Production Machinery - Aquaculture Feeder

Standard: PNS/BAFS PABES 287:2019
International Classification (ICS): 65.060.99
Compiled by: University of the Philippines Los Baños – Agricultural Machinery Testing and Evaluation Center (UPLB – AMTEC) in collaboration with the Bureau of Agriculture and Fisheries Standards (BAFS)
Focuses on the fabrication and performance requirements for aquaculture feeders.

Normative References

Standards (PAES) used in this document and their years: PAES 101:2000, 102:2000, 103:2000, PNS/BAFS/PAES 192:2016, PNS/BAFS/PABES 288:2019
These standards provide requirements and guidance related to safety, operation, and sampling methods for aquaculture feeders

Terms and Definitions

Aquaculture Feeder: A specialized feeder designed for aquatic animal cultivation.
Discharge Rate: The amount of feed discharged per unit time or trigger actuation.
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

Materials used in constructing the feeder must be resistant to water and rust damage.
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
