8 most dangerous invasive fish species in the world

Rainbow trout is a popular fish game and introduced into many rivers and lakes. They have grown rapidly and threatened to eliminate native fish species by eating larvae and also delivering them

1. Salmo trutta

Salmo trutta

Brown salmon is introduced into many cold water bodies all over the world to serve fishing, now adapted and developed well in many places. Brown salmon competes overwhelmingly to reduce the population of native fish species (especially other species of salmon family), amphibians and invertebrates because they eat meat, occupy and compete food. .

Common name: Brown Salmon

2. Cyprinus carpio

This carp is introduced into freshwater areas around the world for food and ornamental purposes. This species of carp is considered a pest as they often quickly reach high density and stir up to reduce the clarity of water, destroy, and turn on the roots of aquatic plants as the habitat of many species aquatic animals.

Common names: carp

3. Micropterus salmoides

Cyprinus Carpio

Because the meat is delicious and attractive in terms of sports, wide mouth bass is widely introduced around the world. This is a carnivorous, voracious, predatory species and eats all day and night. Their food includes fish, shrimp, amphibians and insects.

Common name: wide mouth bass

4. Oreochromis mossambicus

Mozambique Tilapia is popular, imported into many countries around the world for food. Adaptive populations of this species in the wild are the result of deliberately releasing or letting out from their farms. This is an omnivore and they eat almost everything from algae to insects. They form dense populations and lack of food in living water bodies.

Common name: Mozambique Tilapia

5. Lates niloticus

Lates niloticus

The bass of the Nile River was introduced to Lake Victoria in 1954, where it contributed to the extinction of more than 200 native fish species due to their meat consumption and competition of food.

Common name: sea bass Nile

6. Oncorhynchus mykiss

Rainbow trout is a popular fish game and introduced into many rivers and lakes. They have grown rapidly and threatened to eliminate native fish species by eating larvae while also cross-breeding with other species of ana that affect their genomes. In addition, they compete to eliminate some other fish species by occupying their habitats.

Common name: rainbow trout

7. Clarias batrachus

Clarias batrachus

The catfish that eats this voracious meat originated in East Asia and has been introduced to Florida since 1960 to feed. Since then this catfish has been adapted and grown extensively in nature throughout the state of Florida. In the dry season, a large number of these catfish species can be concentrated in several ponds and eat native fish here.

Common name: catfish

8. Gambusia affinis

Imported into many parts of the world with a false view that they are more effective at killing mosquitoes than native fishes eating larvae, this gambu species has been damaging the births. deluded because of their voracious character. The release of gambu species to kill salt larvae is still being carried out by some salt prevention agencies and other pathogenic mosquitoes.

Common names: gambu fish, fish kill bugs
