What is barbed water?

Byhotrephes Longimanus or Byhotrephes cederstroemi , also called barbed water, is a slight freshwater crustacean originally from Asia and northern Europe. It arrived in the area of ​​large lakes in the United States through discharged ballast water at the beginning of the 80s. Years and quickly spread throughout the area. These invasive types of competitions with local food types and have no natural predators. When the ships arrive at the ports, drain water and replenish the tanks and often release organisms they have collected in the last port. Many species that are introduced in this way will not survive, but barbed waters were beneficial in their new environment. Until 2011, the species was fully established in most of the region. This spine prevents the barbed waterfall to eat any kind except the largest fish, so they have no natural predators that limit their populations. They apply from 0.25 to 0.625 inches (6.35 mm to 15.87 mm). They gather in bristle, jellySimilar balls on fishing nets and lines.

The type of Byhotrephes is reproduced sexually or asexually depending on the environment. Females can produce up to 20 viable offspring per month. Bargaining eggs are able to remain sleeping throughout the winter and hatch as temperatures rise.

eggs that are eaten by birds or fish can pass through the body of the animal unharmed. Eggs resist frost and drying. Even the mother dies out of the water and her eggs dry, the eggs can still hatch if they are returned to the water.

barbed water fleas compete with other fish for food, especially the type of zooplankton called Daphnia. In some regions, they have completely eliminated certain native types of zooplankton, limiting the available food supply for juvenile fish that rely on zooplankton to survive. In addition, they clog the fishing eye eye eyes and prevent fish from being caughty.

This species is difficult to check after its determination. Spinate Water Blea easily travels from one place to the other on buckets on bait or in Bilge water, and after the show they quickly colonize new lakes. Since 2011, in Minnesota have been listed as regulated invasive species.
