SPECIES
INDICATIONS FOR USE
FEEDING DIRECTIONS
SALMONIDS
For control of ulcer disease caused by Hemophilus piscium, furunculosis caused by Aeromonas salmonicida, bacterial hemorrhagic septicemia caused by Aeromonas liquefaciens and pseudomonas disease.
Administer medicated feed to provide a dosage of 2.5 - 3.75 g of oxytetracycline per 100 lb of fish daily for 10 days (see finfish mixing directions below). If mortality is not reduced by the fifth day
of treatment, the diagnosis should be reexamined.
Warning: Do not liberate or slaughter salmonids for food during treatment or for 21 days following last feeding of medicated feed.
PACIFIC SALMON
For marking of skeletal tissue.
Administer medicated feed as the sole ration to salmon not over 30 g body weight to provide a dosage of 11.35 g of oxytetracycline per 100 lb of fish (250 mg per kg of fish) daily for 4 consecutive days.
Warning: Do not liberate for at least 7 days following last feeding of medicated feed.
FRESHWATER-REARED
SALMONIDS
For the control of mortality in freshwater-reared salmonids due to coldwater disease associated with Flavobacterium psychrophilum.
Administer medicated feed to provide a dosage of 3.75 g of oxytetracycline per 100 lb of fish daily for 10 days (see finfish mixing directions below).
Warning: Do not liberate or slaughter freshwater-reared salmonids for food during treatment or for 21 days following last feeding of medicated feed.
FRESHWATER-REARED
Oncorhynchus mykiss
For the control of mortality in freshwater-reared Oncorhynchus mykiss due to columnaris disease associated with Flavobacterium columnare.
Administer medicated feed to provide a dosage of 3.75 g of oxytetracycline per 100 lb of fish daily for 10 days (see finfish mixing directions below).
Warning: Do not liberate or slaughter Oncorhynchus mykissfor food during treatment or for 21 days following last feeding of medicated feed.
CATFISH
For control of bacterial hemorrhagic septicemia caused by Aeromonas liquefaciens and pseudomonas disease.
Administer medicated feed to provide a dosage of 2.5 - 3.75 g of oxytetracycline per 100 lb of fish daily for 10 days (see finfish mixing directions below). If mortality is not reduced by the fifth day of treatment, the diagnosis should be reexamined.
Warning: Do not liberate or slaughter catfish for food during treatment or for 21 days following last feeding of medicated feed. Do not use when water temperature is below 62°F (16.7°C).
LOBSTER
For control of gaffkemia caused by Aerococcus viridans.
Administer 1 g/lb of medicated feed as sole ration for 5 consecutive days (see lobster mixing directions below).
Warning: Withdraw medicated feed 30 days before harvesting lobsters.
Note that feeding rates may vary depending on the size and health of the fish. Feeding rates should be chosen to ensure that all fish in the rearing unit are adequately medicated.

* To calculate g Terramycin per ton finished feed at other feeding rates: (desired dose rate/feeding rate) x 2000
To calculate Terramycin 200 for Fish per ton at other feeding rates: g Terramycin per ton finished feed/200
Example: at a feeding rate of 2.5% (2.5 pounds per 100 pounds), with a desired dose of 3.75 g/100 pounds: 3.75 g per 100 lb/2.5 lb per 100 lb = 1.5 g per lb x 2000 lb = 3000 g Terramycin/ton
3000 g Terramycin per ton/200 g Terramycin per lb of Terramycin 200 for Fish = 15 pounds Terramycin per ton of feed
** To calculate total required medicated feed for the 10 day treatment period, multiply total estimated rearing unit biomass by
10 and divide by the pounds of medicated feed needed at your feeding rate
Example: at a feeding rate of 2% in a unit containing 5,000 pounds of fish biomass:
5,000 lb x 10 = 50,000 lb/100,000 lb per ton = 0.5 tons
MIXING DIRECTIONS—Lobsters
Mix 10 pounds of Terramycin 200 for Fish per ton of feed to achieve the dose rate of 1 g/lb.
