Careful management and monitoring of oxygen levels is critical during Salmosan® Vet treatments. A minimum oxygen level should be set by the prescriber prior to treatment. In order to maintain oxygen levels, vigorous oxygenation of the water must be provided during treatment. It is recommended that oxygen addition beings before the tarpaulins are fitted to the pens.
Impaired gill health and concurrent disease such as pancreas disease and cardiomyopathy syndrome has been shown to increase fish mortality post treatment, due to stress related to the treatment and/or treatment procedure.
The product should be applied to salmon suffering from infestations with pre-adult and adult sea lice before the stage at which serious skin damage is evident.
During treatment, fish should be monitored for, but not limited to, signs of stress (lethargy, gasping, orientation problems, balance problems and abnormal swimming behaviour). If any of these signs are observed during or shortly after treatment, flush the treatment area with clean sea water and ensure vigorous oxygenation.
A laboratory study was conducted to determine the safety of treatment at temperatures above 10°C for the maximum recommended treatment duration of 60minutes. Salmon (with bodyweights from 350 g) appeared to tolerate exposure to Salmosan® Vet at up to three times the recommended dose rate (i.e. 0.6 ppm), for up to three times the recommended treatment time (i.e. 180 minutes), at both 6°C and 15°C.

MEDICAL ADVICE TO USERS
•If you have previously felt unwell after using a product containing an organophosphorus compound, consult your doctor before working with this product and show your doctor the product label.
•If you feel unwell after using this product, consult your doctor and show your doctor the product label.
•Treat any cases of heavy contamination as an emergency. You should go straight to hospital after removing contaminated clothing, and rinse areas of skin which came into contact with the product with plenty of water.
•If the product has been swallowed go straight to hospital and take the product label with you.
MEDICAL ADVICE TO DOCTORS
Poisoning from organophosphorus compounds results from blockage of acetylcholinesterase, with a resulting over-activity of acetylcholine.
Symptoms include headache, exhaustion and weakness, mental confusion together with blurred vision, excessive salivation and sweating, cramp-like abdominal pain, chest tightness, diarrhoea, constricted pupils and bronchorrhea. These may develop for up to 24 hours after exposure.
Severe poisoning can include general muscle twitching, loss of coordination, extreme difficulty with breathing and convulsions which may lead to unconsciousness in the absence of medical treatment. Treat symptomatically and seek urgent hospital transfer if poisoning is suspected.
Advice on clinical management is available from the National Poisons Information Service.
Other precautions
The product is very dangerous to crustaceans and is dangerous to fish and other aquatic organisms; therefore the product should not be used in sea farms where crabs and lobsters are kept in close proximity of the treated cages.
Frequent use and/or use on a larger scale may pose an increased risk to the environment. In order to ensure safe use (including large scale and multiple treatments) of the product under a combination of different environmental conditions (e.g. low water current speeds, shallow waters, short distance to the shore etc.), local environmental regulations governing discharges, where applicable, must be adhered to. If there is any doubt about safe use in the environment, relevant competent authorities should be consulted or professional advice sought accordingly.
The most important mechanism for removal of the product in coastal waters is dilution which is increased by water movements including the flushing effects of sea lochs. After treatment, care should be taken to provide sufficient water exchange through the net to dilute residual azamethiphos. The water movements from a boat's propeller may be used to increase water exchange in cases where low water exchange rates cannot be avoided. These measures will help to prevent possible adverse effects on aquatic life.
From a practical use position, 'restrictive tarpaulins' are commonly available now and can be used to reduce the volume of larger net pens for bath treatments. Depending on biomass, these tarpaulins can reduce the size of larger net pens by >60%. This is good practice which not only allows for better measurement of the water volume to be treated but also reduces the amount of product needed to be used and therefore released at the end of treatment.
For countries where an environmental authorisation is not required at each individual site, the following risk mitigation measures should be followed:
At sites with cages ≥ 150 m in circumference, a maximum of one cage should be treated per day.
At sites with cages 120-149 m in circumference, a maximum of two cages should be treated per day.
