The life of an invasive species: Carp By: Ambhikesh Gulasingam

Classification

Classification is a system of categorizing things into subgroups by their characteristics.

Kingdom: Animal Class: Actinopterygii

Genus:Cyprinus Phylum: Chordata

Order :Cyprinforme Species: Cicarpio

Family: Cypriniformes Bio name: Cyprinus Carpio

Characteristics

Characteristics are a distinguishing feature or quality

Behavioral Characteristics

Behavioral Characteristics has to do with how the animal acts

  • Jump out of water at high speeds
  • Feed according to the direction
  • When air pressure drops they stop moving and start to feed on dead material
  • a typical adult female can lay 300,000 eggs in a single spawn
  • Carp typically spawn in the spring
  • Common carp are omnivorous
  • Carp can eat a herbivorous diet of water plants, but prefer to scavenge the bottom for insects, crustaceans
  • Carp will be more active in the summer months due to the water temperature rising
  • Carps normal swimming motion is an S shape. Coming from tail up the body.
  • Usually in the winter carp will just sit motionless this maybe because they are digesting food.

Structural Characteristics

Structural Characteristics have to do with the animals body

  • Weight: 60-110 pounds (Full grown)
  • Eyes lower than most fish
  • Barbels
  • Single dorsal spine
  • Pelvic fin
  • Anal fin
  • Tail
  • Scales
Carp bone structure
Habitats: A habitat is the home of an animal or a plant
  • Carp are found throughout the Great Lakes region from the upper St. Lawrence River to Lake Superior
  • Large and small man made reserves
  • Other Regions: temperate forests, tropical forests, freshwater ponds and Wetlands
  • Prefer Large slow moving lakes with soft debris
  • Carp live in many inland lakes
  • Aquatic ecosystems: benthic zone (lowest level of a body of water), lake ponds and river streams

How do Carp migrate to new areas

Migrating means tomove from one region or habitat to another

In the 1960's and 70's the Silver and Big-headed carp were brought to North America to improve water quality, and boost the result of fishing in fish ponds. After that they were believed to enter different major rivers by other ponds in the 1990's. Now they have started to reproduce rapidly and now are migrating to more lakes by jumping over dams and barriers.

Carps usually migrate in groups

carp impacts

Impact: A impact is to have a strong effect on someone or something

Some animals might have good and bad impacts but carp only have negative impacts

Negative

  • Asian carp can cause serious damage to the native fish populations in the lakes and rivers or they infest bodies of water because other fish struggle with cap with for food and space.
  • Carp are also thought to lower water quality, which can kill off sensitive organisms like native freshwater mussels.
  • Asian carp have been known to takeover entire streams effectively pushing out the native species.
  • Silver carp are known to jump out of the water at high speeds, which can injure boaters and damage boating equipment.
  • Experts are worried that if these fish get into the Great Lakes, they may negatively affect the area's $7 billion/year fishing industry.
  • By out-competing native fish species for food and habitat, carp may reduce the populations of native fish that are so important to fishermen.

What is being done to control carps?

  • State and federal agencies are monitoring the Mississippi River and its tributaries for Asian carp, and studying various barrier technologies that would prevent the further spread of these species.
  • Some carp are tagged therefore scientists are able to monitor there movement so they can strategically barriers and nets to catch carp
  • Some corporations have constructed a barrier on the Coon Rapids Dam to prevent carp from moving up river.This increases the distance between the water above the dam, and the water below so carp can't jump over the barrier.
  • Electrical barriers are being placed at main streams that lead to the Great Lakes.
  • Creating bubbles or annoying sound push carp out of certain area and into areas where they are netted.
  • To prevent these unwanted invaders from coming into the province, Ontario has regulated four species of Asian carp (Silver Carp, Bighead Carp, Grass Carp, Black Carp) as prohibited under the Invasive Species Act.
  • Ecological separation: Ecological separation is when, because of its harm on a species it is removed for the better of the ecosystem.
