About Romet® TC
A new formulation of hydrolyzed fish protein concentrate that significantly improves the palatability of Romet® feeds which treat furunculosis and ESC. Growers can count on effective disease control because better palatability means improved medicated feed consumption and more antibiotic uptake. Romet® TC works by interfering with the folic acid (a Vitamin B) synthesis pathway. For freshwater-reared salmonids (trout and salmon) and catfish.
Production
The “TC” in Romet® TC stands for “Top Coat”. This Romet® TC can be self-applied or applied in the feed mill. The self-application aspect of Romet® TC is what makes the product appealing. Due to the fact that Romet® TC is a top coat, it is 2/3rds of Romet® 30s strength. Romet® TC can be applied to any type of feed.
Withdrawal
Catfish
Romet® TC‘s withdrawal period can be as short as 3 days for catfish. (This means that with a 5-day treatment period and 3-day withdrawal period, a catfish treated with Romet® TC can be slaughtered 8 days after the drug is initiated.)
Freshwater-reared salmonids (trout and salmon)
Freshwater-reared salmonids (trout and salmon) have a required 42-day withdrawal period from Romet® TC before being slaughtered. Withdraw time is impacted by water temperature.
Dosage
Feed between 2%-3% of the fish’s body weight per day.
For further information consult the Romet® Calculator.
Use Directions
Establish the weight of fish to be treated and calculate the amount of feed needed per day according to fish size and water temperature. Administer medicated feed daily for five consecutive days to provide approximately 50 mg of active ingredients per kg (23 mg/lb) of live body weight of fish per day.
Feed Intake of Fish as Percent (%) of Body Weight
| % Body Weight Fed/Day | Pounds of Romet® TC to add to half gallon of water for each 100lbs of feed* |
|---|---|
| 1.0% | 2.50 |
| 2.0% | 1.25 |
| 2.5% | 1.00 |
| 5.0% | 0.50 |
* For metric calculations, the values may be used as kilograms of Romet® TC added to 4 litres of water for each 100 kilograms of feed.
Medicate feed after pelletizing
Prepare a liquid slurry by suspending Romet® TC in water as shown in the table above based on feed intake and weight of fish to be treated. Coat the pelleted fish feed with the slurry, which should be constantly agitated to ensure uniform suspension of Romet® TC during addition. As a general rule, one gallon of liquid slurry is required to 200lbs of pellets.
Pellets may be placed in a cement mixer (if fifty lbs. or more are to be coated) or spread on plastic or a smooth concrete surface for the coating process. The pellets should be mixed constantly but gently while the slurry is being slowly added to insure even distribution without undue pellet breakage. The coated pellets are then spread out and allowed to air dry for several hours.
