The salmon farming industry has significantly expanded in South-eastern Tasmanian both in production and in number and location of farms. Along with this expansion has been an increasing concern from the general community about the effects of salmon farms on the environment. This includes a reported spread of ‘nuisance’ algae in the intertidal zone; however, this has not been verified scientifically. As one of the main effects of salmon farming is an increase in nutrients to the environment from waste products, a possible flow-on effect could be a proliferation of macroalgal beds near salmon farming operations. However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

As one of the main effects of salmon farming is an increase in nutrients to the environment from waste products, a possible flow-on effect could be a proliferation of macroalgal beds near salmon farming operations. However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

However, a survey of intertidal areas in the Huon and D’Entrecasteaux Channel region in 2002/03 found no clear patterns of macroalgal abundance with distance from salmon farms, (Crawford et al 2006), and it was recommended that any future studies focus on surveying the abundance of key species in the intertidal, Ulva spp and Hormosira banksii, which are widely distributed and readily identified.

In this project researchers from the Institute for Marine and Antarctic Studies at the University of Tasmania repeated the survey of intertidal macroalgae conducted in 2002/03 to assess whether abundances have significantly changed at these sites. We also investigated monitoring macroalgal abundance at a larger spatial scale using Unmanned Aerial Vehicles (UAVs), commonly known as drones. Since the previous survey in 2002/03, the technology for UAVs has significantly advanced and they are now a much more cost effective option. However, the techniques and quantitative analyses required to monitor intertidal algal assemblages using drones have not been assessed.

The salmon farming industry has significantly expanded in South-eastern Tasmanian both in production and in number and location of farms. Along with this expansion has been an increasing concern from the general community about the effects of salmon farms on the environment.
