Beauty's Poisonous Fish Species Other Annihilate

Maroon beautiful fish populations but poisonous in the waters of the Caribbean spread, even to shift the local species. Aka prickly fish named lionfish lion fish is often stinging divers. Though these fish originated from the tropical Indian and Pacific oceans. They allegedly fled the Florida fish tank and spread to Cuba, to the Cayman Islands, the main purpose of the divers.

The existence of this lionfish worried enough marine ecology experts, since they quite destroy other native species. A lionsfh could spend 20 small fish within 30 minutes. "There is no way to stop this invasion," said Mark Hixon, marine ecologist at Oregon State University.

Invasion

Besides toxic, it also kills fish prey or enemies with long thorns around its body. Similar cases also occurred in Africa, the Nile perch fishing has destroyed more than 200 species of rare fish. According to the World Conservation Union, the case was entered in the 100 list of the world's worst invasive species.

Lion fish poisonous been held in the Bahamas, where they also prey on all the kids fish. Scientists believe that fish was first brought to malignant Atlantika in 1992 during Hurricane Andrew. These species are not aggressively attack humans, but once bitten it is very fatal poison. Throughout the 18-inch fish was moving rather slowly and in deep water. So who is the most potentially poison the divers.

Carp On The Fly


Insanity or the ultimate stalking experience ?

Year after year we strive to find something different to present carp with, different baits, rigs, hook sizes, floats, just about anything. Carp learn to associate certain sounds, objects (sight), and tastes with a threat. On some waters carp learn to be suspicious in certain areas of the lake but not in others. 2oz weights have a distinct sound when they hit the water, on some pressurized waters the plop of weights can spook Carp, although I suspect that this is limited. What normally appears happens is that the Carp turn round to look for the cause and if nothing moves they soon forget about it. Recasting, a moving shadow or the movement caused by the straightening of a float can definitely spook them at this stage. However, leaves, twigs, ducks, and who knows what continuously land in the water; all are perfectly normal and will not so raise more than an carp's eyebrow. How much more of a dramatic change in presentation could you ask for than to fly line? One this is for sure, carp have virtually never seen a fly line; let alone heard the gentle splash it makes as it lands on the water. All of this is to the fly fisherman's advantage, carp have virtually no knowledge of any associated treat.

A standard fly rod, around a 7 or 8 weight with either a double taper or weight forward floating line will produce good results. The floating line helps, it keeps the line away from the fish who will swim under it apparently not even realizing it's there. If they do notice it, they probably assume it's a piece of floating reed or something. A rod lighter that a 7 weight does not have enough back bone when it comes to playing Carp. Remember you are probably used to fishing a rod with around a two and half pound test curve and now you have dropped to a pound or less. It is quite surprising how light a leader you can get away with. The comparatively soft fly rod provides very high levels of buffering. Start with 9 foot leader with a 6lb tip. You can use a lighter tip, but your chances of losing a strong fish will increase.

You don't have to use flie's, a fly rod makes an excellent tool for casting various different types of bait. The traditional fly fisherman would shy away from ideas such as super-glue and dog biscuits. With a fly rod; you have the opportunity to cast one 20yds from the bank without controller to make a large splash as it lands. Another option is corn on a small hook, size eight for example will sink the corn with no problems. Floating baits will require the leader to be greased so that is floats, sinking baits need a sinking de-greased leader.

Conventional trout flies can be used; large whites can be mistaken for bread floating on the surface. Carp are often the curse of the American fly fishermen, who pick them up on a nymph whilst fishing for lake trout. This can also be used to our advantage. Patterns that work include; blood worm, pheasant tail nymphs, hares ears and olive nymphs, to mention a few. To fish these you will need a very slow retrieve with lots of pauses. A floating line and a sinking leader is best, provided it is not too deep. For deep water a sinking line can be used but this increases the risk of spooking the Carp. A small twitch is enough to get their attention and a small coating of diluted flavor before you cast, whilst not necessary, will help to get a strong take. One fly which is particularly effective and was designed for carp by Tom Conner is the Corn Fly. This consists of a small cube of yellow foam mounted on the hook in a similar fashion to a hair rig. The foam is dipped in flavor before casting and is allowed to sink to where the fish are.

Tactics are very similar to stalking, slow movements and a light foot fall are essential. Use what vegetation there is as cover and wear dark cloths that blend in. Location is definitely king in this game; you need to target individual or small groups of feeding fish. Random casting will not bring results. Polarized sun glassed are essential not only as visual aid but they add a safety factor when you have a hook in the air. Once the target carp has been spotted, there are three main tactics that can be used; which one to choose will depend on their behavior and your casting abilities. The first is to drop the fly "on the fishes head" and allow it to slowly sink. Don't worry about the fly touching the fish, it will feel it, and will probably turn and taste it, if it doesn't a slight twitch of the fly can often provoke a response. The second is to over cast the fish and slowly and gradually retrieve through to the point where the fish are feeding. This method is particularly effective when carp are end up feeding on the bottom, as casting direct to them will only result in the fly being "blown off-course" by their tail finning. The last method is for surface or near surface fish. Cast the fly about six to twelve inches ahead the fish. Moving the fly gently away from the approaching fish ,only an inch or two, will probably result is a definite take if only out of curiosity.

Small flies can often work better than large ones, size 12 is about right. Larger ones can spook fish. since a small hook is very sharp and has no bait in the way, it will penetrate deeply, filling the hook bend. This action combined with the damping effect of the soft rod reduces the strain on the hook and is therefor less likely to result in a bent or de-formed hook. Carp don't chase flies, nor do they take and run immediately. Once they have realized something is wrong, they move off with the hook still in their mouths, you will see the line start to move with them and now is your time to strike gently, after that they really do move. You will need to give line, forget using this method near snags. Letting the fish take all your slack line so that you can play the fish off the reel is essential. Line played in the hand can be very jerky and result in hook pulls. After that is down to you.

They will probably think you are insane, but you will be the one holding the fish.

Arowana Fish Breeding

Arowana fish farming has successfully developed a long time. This activity originated from the enlargement in the aquarium. But in about the year 2000 the Center for Freshwater Aquaculture Development successfully breeding of fish which is said to bring hockey to the owner, naturally.





Gonadal maturation and selection

Arowana fish gonad maturation was conducted in an aquarium. The trick: prepare an aquarium size 80 cm long, 60 cm wide and 50 cm high; dry for two days; water content as high as 40 cm; pairs of two points and turn on aeration during hatching; input a mother Arowana; news feed in the form of small fish or small shrimp, cleaned and replace the water every week. Selection of male to female is still elusive. Until now I still have not differentiate between male and female parent. The author also has not found a reference that explains about it.


Spawning

Arowana spawning ground with the water. How: ready pool size 1000 m2; dry for 4-5 days; fix all the parts thereof; make kemalir a width of 40 cm and 10 cm high; essentially averaged soil; water content as high as 60-80 cm and let it flow continuously; input 50 tails Arowana parent; news feed in the form of small fish and shrimp. let spawn naturally.

Note: Arowana fish will spawn naturally. The food is usually quite done several times only, such as tilapia or a thousand fish, two fish, then it will evolve by itself. Similarly, the shrimp will usually own ketch, because the shrimps including wild animals.

Harvest


Harvest done three months after the rainy season, around July and August. How, surutkan pool water up to as high as 20-30 cm or up to an altitude where the seeds could be arrested; catch Arowana parent with a fine net sekup; input into the plastic and fine accommodation in hapa installed near the pond spawning; also catch the seeds; input into the bucket ; density into the aquarium that had been prepared, with its completeness.

Note: To avoid disruption during the next spawning, then the wild fish, especially tilapia caught. After the completion of harvest, all the pool repaired, especially the dike, coated with a land base, if any leak was dismantled and closed again with earth




Prettiest Fish in the World

10. African Cichlids

This fish is pronounced as "Sick-lids." This fish is found in three lakes in Africa: Malawi, Tanganyika, and Victoria. Existing species in Lake Victoria the number is less diverse and less colorful than others. They usually grow to 6-7 inches, with the exception of Species Frontosoa, who can grow until 12-14 inches. This is ikan2 Ikan2 freshwater dipiara who could easily in a home aquarium. DiAfrika addition, there are also species of this fish in the waters of the Amazon who idup, but it was bigger and more aggressive than the antecedent of Africa.

9. Parrotfish



So called because the shape of bird beak-like mouth. This fish who uses her mouth like the beak to break down and eat the small invertebrates living in the area of coral. Usually they will eat the whole rocks and coral or sea sand munching abyssal invertebrates, then discard the rest of it.




8. Regal Tang


This is the fish in Finding Nemo is not it? Btw, this fish is considered in the Surgeonfish family, who have small knife from the lime who can be hidden in front of its tail fin. This small knife is used primarily for defense systems in the face of predators.





7
. Coral Beauty



This fish is categorized in angelfish. This fish can be stored in a home aquarium and can survive well in their habitat (hardy).








6. Flame Ange


This fish memikiki close relationship with the Coral Beauty. Same nature as the Coral Beauty, but nature does not 'seteguh' Coral Beauty.







5. Koi



There are many color variations of koi fish (about 100an). Koi can have orange, red, white, golden, or black. Some koi enthusiasts willing to pay thousands of dollars for a koi simply to find who koi rare color patterns.






4. Moorish Idol


This fish is considered difficult to dipiara in home aquariums, and also very expensive. In the source who read the cave, there is more information ga for these fish. Want googling?





3. Lionfish




Iit is also called Zebrafish. It has a poisonous spine in great painful and quite effective. People who take care of them surely have to be careful if you want to clean the tank







2. Discus


This fish is a species of freshwater fish is a fish who may be the most beautiful fresh water. The price is also very expensive: tillers who three inches in length ranging from $ 50 - $ 80.








1. Mandarinfish



There are two varieties of this species: Mandarinfish standards and Psychedelic Mandarin. The standards usually have a color pattern and who better than the Psychedelic. Ga lebihdari price $ 20 per cow, but off-the problem was the food.
