Toxic hobby

It is very rare that you get to know about it or the fish are poisonous, and therefore should be cautious in their daily dealings with it. Actually it’s amazing that no more accidents around the home how to make extra money.

It arouses disgust in most people, when facing a person who has poisonous snakes or large tarantulas as pets, because we know that it is very poisonous animals, they’re doing. Yet we hear very seldom that there have been major incidents with these animals, and it hangs together with the fact that these people know what they’re doing – they know that these animals are poisonous and therefore dangerous.

It is immediately different when we talk about animals as you do not know is toxic, and within our hobby, there is some fish are not only toxic, but also very commonly found in trade.

Okay! – Let it be said immediately – there is a difference between fish toxicity and there are also differences in how each person reacts to each married – if anything happens.

Here, some factors are, first, how much poison you have been in themselves and in what condition you are in. Small children and old people are more likely a young person with a good level of fitness. But allergy sufferers or people with heart failure are at great risk.

But let us look at what kind of poisons as the toxic fish is equipped with:

The toxins that fish are equipped with can be roughly divided into two main groups: one is poison produced by ordinary slimkirtler, and the other is poison produced by the true poison glands. Common to them is that the communication is of glands which are equipped with hard spines.

These spines are usually located in the dorsal and anal fin, but the glands can also be equipped with tags that are predominantly located on the gill covers or on the tail.

By poisoning from toxic slime (slimkirtler) can plug itself be extremely painful, but severe cases of poisoning are rare. Here, just kicked a footnote in:

There are differences in toxicity and infection. The connector of fin rays or tagger – even with non-toxic fish – transferred often bacteria of various kinds to the wound, where they can cause infections – this is also true with our domestic Sculpin, it is not toxic, but can easily cause infection when sticks on it.

Toxic secretions produced by slimkirtler, combined with hard spines, found in some perch species, but also in the saltwater aquarium frequent Surgeon Fish. Surgeon Fish is on each side of the tail equipped with a razor blade-shaped spike.

Zebrasoma flavenscens

After injection of slimsekret of Surgeon Fish, one could detect a non-bacterial infection in experimental animals. The toxinske effect does not exclude the connector to a bacterial infection may encounter the same time and in the internship is it also natural that both exist simultaneously.
Zebrasoma flavescens (Yellow surgeon) is like all the other surgeon fish, equipped with a poisonous spike on both sides of the tail.

The fish are holding right poison glands are Rabbit Pisces Siganidae, which is also very common in saltwater circles. At Rabbit Pisces is the front fin ray in the back equipped with giftkirtel, but some species within this genus also have poison glands in some of the breast fin rays. Finn Rays with poison glands in the dorsal and pectoral fins are covered with skin tissue. Damage to these fish easily occurs when trying to capture or hold them firmly in hand.

Such plugs are very painful, swollen and gives an attack site, but also local damage of lymph nodes can occur. If larger quantities of poison inserted directly into the blood, symptoms can be harder ÂndingsbesvÊr and reduced heart activity occurring. Symptoms disappear after 2-3 days.

Lo vulpinus belongs to the rabbit fish, and as such is also equipped with poison spikes in the front of the dorsal fin.
Lo vulpinus

Other fish with true poison glands can be found among the Rays and some smaller sharks, but these come aquarist rarely in contact.

Many aquarists are blissfully unaware that even some catfish have similar poison glands, and this should be noted that they so popular small Pansermaller not belong to them.

In families, Schilbeidae, Clariidae and Ictaluridae can we find hard spines that are equipped with poison glands. In these families, we also find it commercially commonly occurring Congo-glass catfish, all species within Clarias and Schilb. and the North American Catfish.

Of catfish in salt water is the only coral catfish, Plotosus lineatus, as we come near the aquarium community.

Silurido toxin as mallernes married name, also produced in detteher case of poison glands, located at the harsh rays of the spine, dorsal and ventral fins. These rays – which in some cases are shaped like sharp spikes – often have a sort of locking mechanism can lock the fin rays are stuck in extended position.

Poisoning of Siluridotoxin is familiar because it is not rare to fishermen in Africa and North America puts on them. Even small specimens can be dangerous, and examples of hobbyists who have stabbed himself in a Clarias, and then become so ill that they had to be hospitalized, are well known.

Poisoning with Siluridotoxin primarily provides a strong pain attack instead. Later, following an increase in cardiac and respiratory activity, which later turns into the opposite ditch, and has gained much poison in itself can cause an arterial blood pressure, which together with the above may result in unconsciousness.

Very toxic fish, we find the families, Trachinidae and Scorpaenidae, and within the genera Pterois and Dendrochirus.

At the first family we find Face Nobody Trachinus draco, the only poisonous fish we have here at home – Okay, it is not widespread in the aquarium community, but cases of poisoning among fishermen and bathers on the North Sea and the Sound, is “widely” available. Its poison – Trachinid toxin – provides intense swelling and affect the heart activity.

Within the family Scorpaena, the potency of the venom varies greatly from species to species. Species from the colder waters rarely severe poisonings, but the situation is quite different from their relatives from warmer climes.

The Mediterranean fish occurring within the family is Scorpionfish Scorpaena or rockfish, if you will, is equipped with several poison spikes: Two of these are at the forefront of the dorsal fin, and there are 3 of the anal fin, and one in each pectoral fins.

These spines are all equipped with well developed poison glands, and a cross section of these spines shows that they are triangular or T-shaped. The poison glands found in the deep grooves that run along fin rays.

The effect of the toxin – called Scorpaeno toxin – has put gray hairs on the scholars for some time. In laboratory studies of their venom, you could only find minor reactions in laboratory animals. Later it was discovered that Scorpaenatoxin is very fragile in terms of contact with other liquid substances – including excluding water.

But not enough. Scorpaenatoxin is also sensitive to heat, and possibly also to light. These factors reduce the efficiency quickly marry, but married transfer directly from the fish, has a very strong effect on the victim:

Attacks place swells up, and so does the lymph nodes, which is incredibly painful. Through the lymph nodes spread poison throughout the body and can be sufficiently large quantities of lower activity of the heart, trigger convulsions in the arterial system and cause acute paralysis.

Also bacterial infections are very common after an attack from a rockfish.

Dragon Fish from the genera Pterois and Dendrochirus should have separate consideration because they are very commonly found in trade, and as such also often found among the private aquarist. At Dragon fish are the hard spines in dorsal, anal and pelvic fins equipped with poison glands. The spines and poison glands are covered by skin tissue, and secretion of toxin occurs by finn the beam tip.

The venom of the lionfish – Pterois labeled toxin – may seem very different on the individual victims, but even very small plugs are extremely painful.
Dragon Fish

Plug with very little toxinsk effect can easily give a perception that the venom from the Dragon Fish may not be particularly harmful – but it can be a fatal mistake …

While the pain and agony psychological effect, there is a very fast drop in blood pressure that affects cardiac activity. In addition, the poison destroy the red blood cells. The fall in blood pressure can at worst lead to an inadequate supply of blood to the heart, with permanent injury to follow (like a heart attack).

Severe swelling of the attack site and lymph nodes, as well as ataxia (inability to control muscle movements), and paralysis are other symptoms that may befall. Even death through paralysis of the diaphragm and heart failure is well known.

The poison inactivity slowly by the liver and excreted by the kidneys in about. 70 hours.

Pteroistoxin is a tough, colorless liquid that quickly loses its effect when it comes into contact with liquids other than water, or heated to a temperature higher than 500C. In the frozen state can poison the other hand, retaining its toxicity over time – something you should be aware that if you want to freeze her dead lionfish for later studies (?!).

Also stone Pisces are extremely poisonous lionfish – they are equipped with fish fauna most efficient stabbing weapons – and the difference between them and the lionfish is that ambulance to drive even more hazardous by the city.

The venom like a stone fish are equipped with are the most dangerous and most toxic of all poisons fish we know today.

The poison is called Synanceiatoxin and when it ends up in your body, you are unwell and have severe vomiting and a rapid temperature drop is not unusual. You become short of breath and respiration becomes very large. This falls later so strongly that there is paralysis of the diaphragm and cardiac arrest. When slightly poisoning cases occur acute paralysis of the arm-leg and back muscles.

The poison is in the research community as compared to the dreaded Indian arrow poison curare.

Fortunately, stone fish color and body shape in a way that you do not get the big aesthetic thrill – they look like a stone and behaves as such ..! Fortunately, it is also true that these highly poisonous fish are extremely rare in the trade, and therefore not widely used around the home …

There is thus some fish (and also evertebrater) which is more or less toxic – including why it is so important to know the animals that you buy.

But let it be said right away: the different poisons that we may encounter in the aquarium hobby, works differently from person to person, it means that children, elderly people and those with poor cardiac and / or lung function, is a greater risk for severe cases of poisoning than young and healthy subjects.

But nevertheless, one must engage in serious reflection on it is worth the risk, to have with these fish do. One should not just think about themselves:

Other pets (cats, dogs) and small children may inadvertently come to these fish in an unguarded moment, and it would be disastrous to lose a family member because of one’s own fascination for the dangerous …
