Dreissenid Control Efforts

This table summarizes open water dreissenid mussel control projects (Dahlberg et al. 2023) and was reproduced from that publication as an AirTable. The table and publication summarize dreissenid control projects in different lakes across North America. Projects to control dreissenids after 2023 (the date of the Dahlberg publication) were appended to the table.

 

 Project goals:

  • RRE = rapid response eradication

  • EPE = established population eradication

  • S = suppression

  • R = research

 

Pre- and post-treatment surveying types:

  • Cage = monitoring dreissenid mussels held in cages or chambers in the waterbody

  • DS = diving survey

  • eDNA = eDNA sampling

  • Equip = equipment inspection

  • NMI = assessment of native mussel infestation (i.e., density or number)

  • Plate = settlement plate use

  • Quad = dreissenid density at a given location (i.e., plot or quadrat)

  • Rake = inspection of removed vegetation (i.e., by rake toss)

  • Snork = snorkeling survey

  • UWA = assessment of underwater attachment to substrates and macrophytes

  • Vel = veliger tow

  • Video = underwater video inspection

  • Wade = wading survey

  • Wood = measuring attachment to submerged woody surfaces (i.e., density, total number)

 

Non-target monitoring types:

  • AP = aquatic plants (macrophytes)

  • Bac = bacteria

  • BI = benthic invertebrates

  • Chl = chlorophyll

  • Fish = fish

  • NM = native mussels

  • Peri = periphyton

  • Phyto = phytoplankton

  • Zoop = zooplankton

 

Environmental and water chemistry metrics:

  • Alk = alkalinity

  • NH3 = ammonia

  • BDO = benthic dissolved oxygen

  • BOD = biological oxygen demand

  • Ca = calcium

  • COD = carbonaceous oxygen demand

  • Cl = chloride

  • Cond = conductivity

  • Cu = copper

  • DOC = dissolved organic carbon

  • DO = dissolved oxygen

  • DP = dissolved phosphorus

  • Hard = hardness

  • Mg = magnesium

  • Nit = nitrate or nitrite

  • pH = pH

  • K = potassium

  • Prec = precipitation

  • Na = sodium

  • SO4 = sulfate

  • TN = total nitrogen

  • TP = total phosphorus

  • TSS = total suspended solids

  • Turb = turbidity

  • Temp = water temperature

  • WD = wind direction

  • WS = wind speed

 

Outcomes (Projects that treated 100% of the waterbody, or 100% of the shoreline do not have OT responses):

  • ST = short-term (before post-treatment sampling or within one year)

  • LT = longterm (after post-treatment sampling or after one year)

  • IT = within treated area

  • OT = outside of treated area

  • Y = dreissenid mussels present

  • N = dreissenid mussels not present

  • U = unknown

 

Christmas Lake - 2014 treatment with EarthTec QZ - Initially no barrier was installed; copper concentrations decreased from 1 to 0.5 mg/L Cu within 8 h, prompting installation of a floating barrier.

 

Lake Independence - 2014 treatment - Veliger tows taken during the treatment; came back with no veligers present.
