COLOMBO 250 ml Leaflet for Morenicol Lernex

Product Information

Morenicol Lernex is a medication that is effective against various parasites that can affect pond fish. It can be used to treat skin flukes (Gyrodactylus), gill flukes (Dactylogyrus), internal worms (Nematodes), leeches (Piscicola), fish lice (Argulus), and anchor worms (Lernea). The medication is available in three sizes: 250 ml for 5,000 ltr of pond water, 500 ml for 10,000 ltr, and 1,000 ml for 20,000 ltr. It is important to determine the volume of the pond accurately as the dosage of the medication depends on the pond’s volume. Good water quality is essential for the medication to be effective, so it is recommended to test the water quality before and after treatment and correct it if necessary. The medication can be repeated after 14 days if needed. It is important to note that the activity of the parasites may increase after administering Lernex to the pond, which can cause irritation to the fish. It is recommended to observe the fish well during and after treatment.

Product Usage Instructions

Calculate the volume of the pond to be treated as accurately as possible: length x breadth x average depth x 1000 = volume in liters.
Test the water quality before and after treatment and correct it if necessary.
Remove carbon and zeolite during treatment; UV lamps and ozone should be switched off 1 week after the last administration.
Keep the biological filter in function.
Determine the appropriate dosage of Lernex based on the pond volume and administer it to the pond.
Observe the fish well during and after treatment.
If needed, repeat the treatment after 14 days.
During treatment, give animals (e.g. dogs and cats), who regularly drink water from the pond, a dish of water.
Do not combine Lernex with other products without consulting a professional.

INTRODUCTION

Lernex is effective against skin flukes (Gyrodactylus), gill flukes (Dactylogyrus), and internal worms (Nematodes). The presence of these parasites can only be determined with a microscope. Lernex is also effective against leeches (Piscicola), fish lice (Argulus) and anchor worms (Lernea). The presence of these parasites can be determined with the naked eye.

Determination of pond volume

Calculate the volume of the pond to be treated as accurately as possible. In meters: length x breadth x average depth x 1000 = volume in liters.
Morenicol Lernex is available in the following sizes: 250 ml for 5,000 ltr of pond water, 500 ml for 10,000 ltr, and 1,000 ml for 20,000 ltr.

Water quality

For an optimal effect of the treatment and for a quick recovery of the diseased fish, good water quality is essential. Hence, always test the water quality before and after the treatment, and correct it when necessary.

Dosage: 20 gr (=1 measuring spoon) per 500 liters of pond water. Use the included measuring spoon provided to measure out the required amount of Morenicol Lernex. Make a premix of this with water in a bucket or watering can. Dose evenly over the surface of the pond. Below 10°C Morenicol Lernex is absorbed insufficiently by the parasite, it’s recommended to increase the water temperature to improve absorption. When needed the treatment can be repeated after 14 days. Remove carbon and zeolite during treatment; UV lamps and ozone should be switched off 1 week after the last administration. Keep biological filter in function.

Warning: At first, the activity of the parasites can increase after administering Lernex to the pond. This irritates the fish which flash through the water and can even jump out of the pond. Hence, observe the fish well during and after the treatment. Lernex is harmful to freshwater lobsters, beetles, dragonfly larvae, and to snails. Only for use on ornamental pond fish. Keep out of reach of children. Store in the box, dry and dark at a temperature of 4 to 32°C. Do not inhale. Avoid contact with eyes and skin. Close package carefully after use.

Decomposition

Added therapeutics will disappear automatically from ponds because of natural processes, such as oxidation and decomposition by means of bacteria.

The effect upon other animals: Pets and birds drink water from the pond to which this medication has been added. In general, it is thought that, if fish can swim in the water, it is harmless to animals who drink from the same water. Nevertheless, it would be advisable during the treatment, to give animals (e.g. dogs and cats), who regularly drink water from the pond, a dish of water.

Combinations: Between the administration of Morenicol Lernex and Morenicol Alparex, there has to be a waiting period of 2 weeks. The effect of a combination with other products is at your own risk.

Information

Fish lice, gill lice, and anchor worms are different as their names presume, no lice and no worms, however a kind of crustaceans: the parasitic crustaceans. Fish parasites are cold-blooded, which means that, at lower temperatures, their metabolism reduces. Below 10°C Morenicol Lernex is absorbed insufficiently by the parasite, it’s recommended to increase the water temperature to improve absorption.

Fish Lice (Argulus) can grow to a length of ½ cm. They have flatted bodes and are round in shape. They possess many appendages on the belly surface. They attach themselves to the fish by means of two suckers and then use their piercing mouth parts to bore through the skin. They feed on the bodily fluids of the fish. Infested fish become thin and rub themselves on the bottom of the pond and on plants. Argulus lays its eggs in the water. These produce larvae which, if they are to survive, must parasite a fish within one day. These produce larvae which, if they are to survive, must parasite a fish within one day. The reproductive process is stopped at temperatures below 14°C. This means that lice problems occur mainly during the summer months.

Gill Lice (Ergasilus) are smaller than fish lice. They attach themselves to the gills, which they use as a ‘grazing’ area, by means of small hooks. This can result in inflammation of the gill tissues. The end result is usually tissue death and thickening of the gills. Infested fish suffer from a lack of oxygen and may even die.

Anchor worms (Lernaea) can grow to a length of several cm. They are not actually worms be belong to the crustaceans group and are therefore related to the parasitic lice. They breed on the gills and it is only the females that can cause damage. These attach themselves firmly to the fish and bury their anchor-shaped head into the tissues. The first symptom is bleeding in the skin of the fish. This can be noticed as a red spot on the body of the fish. When the parasite is mature we observe the 2 cm. long body, with its two egg pouches, project out from the fish as a “V”. When they become detached, anchor worms leave an ulcerated area behind. The eggs become larvae and these then start up a new cycle of infestation.

Skin- and gill worms

are flattish trematodes, 0,3-0,5 mm in size which were previously relatively uncommon in pond fish. However, nowadays they are regularly encountered. Gyrodactylus is a skin worm. This worm gives birth to living young and is therefore capable of rapid and massive reproduction. The resultant skin irritation gives rise to the thickening of the skin and to the production of a slimy mucous layer over the skin. The gill worm is called Dactylogyrus. This parasite lays eggs. It causes damage and irritation to the gills with resultant thickening and loss of full function. Infested fish rub their gills on plants and stoned. In advanced cases, they swim with the gills permanently opened and they can even die.

Internal worms- Roundworms (Nematodes) are large, roundworms occurring in the digestive tract. Their larvae are also transmitted by, for example, weevils in the food. Some larvae migrate throughout the body of the fish and encapsulate in the muscles and organs. Under certain circumstances, these dormant larvae can mature into adult worms. Fish affected by these worms become thin and have slimy feces.

Leeches (Piscicola geometry) are worm-like creatures with two suckers, a smaller one that also functions as a mouth and a larger one at the tail end. They are marked with horizontal stripes and grow to an average of 2 to 4 cm in length. Leeches use the tail sucker to attach themselves to stones and plants where they wait until a suitable host passes by. When such an opportunity presents itself, they propel themselves in a fraction of a second onto the fish and there attach themselves with the oral sucker. As is the case with the oral sucker. As is the case with all blood-sucking parasites, leeches can transmit a variety of infections. Infested fish become hyperactive and rub themselves against objects. All these parasites cause damage to the skin, which can be inflamed by bacteria and fungi. This can be avoided by using Morenicol Cytofex and Morenicol FMC-50.
