Parasite Identification Part 2


So, lets discuss some more parasites, these may be a little less common in your aquarium but are still rife in ponds.

 

Costia (Ichthyobodo necator)

Costia is a parasite commonly found in pond livestock, this parasite is difficult to spot unless using a high magnification as it is minute however there are some tell-tale signs of costia being present on your fish which includes some of the following symptoms i.e. Sunken eyes, laboured breathing and excess mucus build up to name a few. This parasite attacks both the skin and the gills of its host.

The best way to find costia when taking a mucus scrape from your fish is to add a drop of water to your slide and carefully scan the slide & edges of the mucus this is where this parasite is most obvious. There are a couple of different options you could use when treating costia the most common are linked below;

NT Labs Trearments 

Also available is a new product called Cloverleaf Absolute Potassium Permanganate

In ponds having lots of floating plants and marginals will also help to create escapes from the heat, direct sunlight or potential threats (herons etc.) With this parasite the quickest solution and best treatment in my opinion would be FMG mixture.

 

Gill Flukes (Dactylogyrus)

Dactylogyrus another very common parasite better known as gill flukes, this parasite is not visible to the naked eye however, it is obvious to spot under the microscope. This fluke is an egg layer and prefer warmer temperatures to reproduce as the cooler temperatures slows them down quite considerably. There are a couple of treatments which can be used for this parasite in both an aquarium and ponds I have listed a few below;

Fluke Solve

or a product more commonly used for ponds is NTlabs Flukasol

Also available is a new product called Cloverleaf Absolute Parasite

 

These are just a couple of examples of what are available to target and eliminate these parasites. It’s always worth bearing in mind these parasites reproduce at such a rate that a second dose is almost always advisable to eliminate them especially as most treatments available will not treat the eggs. This parasite primarily targets the gills of your livestock however the eggs are released into the water and once the larvae hatches it needs to find a host within 6-8 hours in order to survive, in higher temperatures they hatch in around 4 days.

 

Trichodina

Trichodina (trich) is a parasite more commonly found in ponds, This parasite can cause severe damage to your livestock and reproduces at a rapid rate, they hook themselves onto your fish and are disc shaped under the microscope and reproduce by division. This parasite moves very quickly in a circular motion and is a great swimmer.

The best treatment for this parasite is listed below although there are others available however a secondary dose would be necessary with this parasite;

Cloverleaf Absolute Potassium Permanaganate or Cloverleaf Absolute Parasite

Or alternatively Kusuri Potassium Permanganate

Temperatures should always be considered when using any treatment and you would need to supply extra aeration whilst using any potassium-based treatments as this treatment is well known for reducing oxygen supply.

 

This is only a very brief description of each parasite to give you a glimpse, they each have life cycles which should be taken into account when using any form of treatments, Before using any treatment please always check the bottles for best results and ideal temperatures to treat your pond effectively. Keep your eyes peeled for more parasite ID soon…
