We hope you are all still healthy and making the most of the lock-down. The Fish Passage Action Team are taking the time to put together more resources to share with our growing audience.
Below is a link to a short video showing the challenges migrating elvers meet, even from their own species, when obstructed by man-made barriers such as perched culverts.
In nature, migrating fish will encounter delays due to natural features, however many have evolved to make mass migrations to ensure that at least some will get through to continue the breeding cycle.
Man-made structures and/or barriers interfere with this process and upset the natural balance of freshwater species.
It is not uncommon for other species, such as birds or rodents, to also take advantage of any delay in upstream migration. To grab and easy meal.
Enjoy.
