NTGCICP Glossary

Revised vice Memorandum of Agreement 2010, Amended August 2010


Alleged- Fish that are declared or stated to be as triploid.

Calibrate- A procedure to standardize equipment or instrument for accuracy by determining its deviation from calibration references and applying any necessary correction factors.

Certification- Obtaining a certificate via the inspection process indicating the triploid grass carp inspected are triploid and do not contain diploids within the limits of the NTGCICP.

Certified Fish Health Specialist- Professional who specializes in the causes, nature, and control of the diseases of non-mammalian aquatic animals.

Certified- Holding or guaranteed by a certificate.

Channelize- Activating the electronic function on the coulter counter to provide a visual frequency-volume histogram indicating the size distribution of the particles.

Channelizer- Electronic part of the coulter counter that provides a frequency-volume histogram, indicating the size distribution of the particles.

Confidence Limits- A pair of numbers used to specified probability that the population characteristic (diploid) is included between them.

Containment Units- Vats, tanks, raceways, tubs, and troughs used to hold water and live fish.

Coulter Counter- Instrument for counting and sizing particles.

Diagnostic Services- Service offered to detect and identify the cause and effect of the nature of anything.

Diploid Controls- Grass carp that have been tested for ploidy and determined to be diploid and therefore, blood from these fish can be used to verify the working order of coulter counters.

Diploid- A cell or organism having two sets of chromosomes.

Fees- Money collected for inspection services which can include fees for non-compliance of the standards.

Fish Veterinarian- Doctor of fish medicine

Flow Cytometer- Instrument used for counting, sizing, and sorting microscopic particles by shining a strong, focused beam of light on the particle or cell and then measuring the scattered light.

Force Majeure- A natural and unavoidable catastrophe that interrupts the expected course of events.

Grass Carp- (Ctenopharyngodon idella) - a herbivorous, freshwater fish that was introduced in Europe and the United states for aquatic weed control.

Hold Harmless- A phrase used in contract law to signify a commitment by one party to make good or repay another party in the event of a specified loss.

Identified Lot- Group of Grass carp that are present in a containment unit that have been tested for ploidy.

Indemnifies- Pay for loss or damage, compensate, reimburse; insure against possible loss or damage.

Inspection- Service provided by a federal grass carp inspector that monitors a sub-sample of alleged triploid grass carp using a coulter counter to ensure that they are indeed triploid.

Inspector- Federal employee or their designated agent who have been trained to perform inspections of triploid grass carp.

Lacey Act- Conservation law that prohibits the transportation of illegally captured or prohibited animals across state lines. This law is primarily used to prevent the importation or spread of potentially dangerous non-native species.

Lot- The number of certified triploid grass carp to be sold and shipped within 6 calendar days from the inspection. The maximum fish per lot is 6,000.

MOA- Memorandum of Agreement: A document written between parties to cooperatively work together on an agreed upon project or meet an agreed upon objective. The purpose of an MOA is to have a written understanding of the agreement between parties.

No Warranty- No guarantee, certificate indicating responsibility; authority; justification.

Participating States- States that voluntarily chose to only accept fish that have been certified by the National Triploid Grass Carp Inspection Certification Program.

Particle Sizer- Operational Coulter Counter used to check ploidy.

Pathologist- Individual that specializes in the study and diagnosis of disease through examination of organs, tissues, bodily fluids and whole bodies.

Placard- Sign or sign-like device attached to or hung from a vehicle to indicate information about the contents of the vehicle.

Ploidy Test- Test used to determine the number of copies or sets of chromosomes present in a particular biological cell.

Polystyrene Beads- The most common form of plastic, solid polystyrene is a hard, colorless plastic that is semi-rigid and limited in flexibility.

Producer- Companies who produce triploid grass carp for sale.

Sale- Agreement where fish are transferred from the producer to the buyer for a fixed price.

Shipment- Fish that are sold to a customer and leave the grass carp producer’s facility.

Stakeholders- Those who have a vested interest in or may be impacted by the success of the program.

Standards- Set of guidelines and protocols used to govern the NTGCICP.

Sunset-Clause- Provisional part of the MOA that terminates or repeals all or parts of the MOA at a specified time period, unless the MOA is renewed.

Tenets- Any opinion, principle, dogma, or doctrine which a person or group believes or maintains..

Tested Fish- The grass carp producer has taken a blood sample and analyzed it for ploidy using a Coulter Counter.

Tetraploid- Organism that has four times the haploid number of chromosomes in a cell nucleus.

Triploid- A cell or organism having three complete sets of chromosomes.

Type A Failure- (true failure): when a diploid grass carp is found during an inspection within a lot of alleged triploid grass carp.

Type B Failure- Equipment or other non-compliance failure of the grass carp standards.

Untested Fish- Fish that have not had a blood sample taken for ploidy testing.

Vat- A large tank that holds fish and water for observation and inspection by the grass carp inspector.
