AIS: Threatening the Public’s Angling and Boating Recreation

Aquatic Invasive Species (AIS) are threatening the public’s angling and boating recreation and our state’s water and electrical infrastructure. It is critical for anyone who owns or uses watercraft, or has a business reliant on watercraft, to understand the essential nature of this aquatic invasive species containment effort by the Arizona Game and Fish Department. The spread of quagga mussels and other aquatic invasive species has far-reaching impacts, both financial and ecological, that can touch virtually every resident of the state. Whether you fish, or boat, or simply get water and electricity to your home, these aquatic invaders WILL affect your lifestyle…and possibly your wallet.

About Aquatic Invasive Species

Quagga mussels

Quagga mussels were first found in Arizona in Lake Mead in January of 2007. They originally came from Eurasia and became established in the Great Lakes in the 1980s. Since being discovered, these prolific invaders have spread rapidly.

new zealand mudsnails

The New Zealand mudsnail is an invasive snail that is ovoviviparous (live bearing) and parthenogenetic (reproduces asexually). Therefore, it only takes one snail to start a new population.

golden alga information

Golden alga releases unique toxins that affect gill-breathing aquatic organisms (mainly fish and clams). The alga is a rapid growing and resilient algae species, out-competing other algae for nutrients and thriving in a wide variety of environmental conditions.
