Additional Details to know before recieving Mosquitofish

Before distribution, District staff must first determine if mosquitofish is the appropriate method to control mosquito larvae in the water feature. Other environmentally conscious and effective treatment options are also available free of cost. 

Information needed from Alameda County residents for mosquitofish:

• Contact information: Name, street address, phone number
• Size of water feature (gallons or square feet)
• Has the water been treated for chloramines?
  • Tap water in Alameda County contain chloramines, which are toxic to mosquitofish and do not evaporate from water if left standing overnight. Water must be treated for chloramines (different than chlorine) before mosquitofish are added using a tap water conditioner or chloramine treatment kit. These are found at aquarium or pet supply stores.

It is against California Department of Fish and Game regulation for private citizens to plant mosquitofish in waters of the state without a permit (Title 14 CCR, Fish and Game Code, Section 1.63, Section 6400, and Section 238.5). Do NOT introduce mosquitofish to rivers, stock ponds, lakes, or creeks.
