Lernaesis (Anchor Worm)

Caused by the parasites Lernaea Sp. Commonly infecting Grass Carp, Javanese Carp, Kissing Gourami, Giant Carp, Large Headed Carp and Common Carp. These parasite invades the body (outer surface) of the fish by sucking the bodily fluids thus causing tissue damages to the head, eyes, tail and fins.

Signs Of Disease

- There are red signs on the body

- Usually small fishes will die and large fishes will experience a lack of weight.


Treatment

1. Sodium chloride (salt) from 8 ppm to 11 ppm for 10-15 minutes. Once every week for 4 weeks.

2. Dipterex 0.25 ppm once in every week for 4 weeks consecutively.

This parasite invades the outside of the body by sucking blood on the head and tail fin just like a vampire.

Signs Of Disease

- Fish becomes thin due to loss of body fluid sucked by the parasite.

- There are traces of blood on the body where the parasite are staying.

- Deaths will occur if the number of parasite are too high.


Treatment

1. Potassium permanganate 10 ppm for 30 minutes max.

2. Dipterex (Masoten or Trichlorfon) 0.25 ppm once in every week for 2 weeks


Fish ponds (Earth Pond) affected by this disease must be dried and limed at the rate of 1.5 tonnes per hectare.

Gyrodactylosis

The causative agent for gyrodactylosis is Gyrodactylus salaris (a small parasitic flatworm). Usually attacks Marble Goby and Common Carp. This parasite invades on the body surface only. Important: fishes with disease may show one or more of the signs below, but disease may still be present in the absence of any signs. On the pond or tank level, you may see the fishes scrubbing (rubbing against objects in response to skin irritation) and flashing (darting and twisting of fish and erratic swimming).


Signs Of Disease

Same with white spots disease

Signs Of Disease

- Gills will appear bloody and there will be excessive mucus (early stage)

- In serious condition, gill filament will corrupt and the fish can't close its operculum properly resulting in breathing difficulties.


Treatment

1. Sodium chloride 10 to 15 ppm for 10 to 15 minutes
