Love Me Fish & Lobster Case Study

Sedimentation Build-Up Limiting Boat Launch in Harbour.

Customer: Love Me Fish & Lobster.

Problem: Sedimentation build-up at the boat launch in harbour.

Solution: Bathymetric survey conducted by Sludge Mapper revealed the extent of the problem and helped determine its root cause.

Client Introduction:

Love Me Fish & Lobster is a seafood company that specializes in lobster distribution and is in Antigonish, Nova Scotia.


Love Me Fish & Lobster was having issues launching their boat via the concrete boat launch located within the confines of the harbour. Unless it was high tide, the boat would run aground only a few meters into the water. They knew sedimentation build-up was the issue but wanted a bathymetric survey to determine the extent of the sedimentation build-up throughout the harbour.


Love Me Fish & Lobster knew that Sludge Mapper conducted sludge surveys of wastewater lagoons and asked if a survey could be conducted on the harbour bottom. They were looking for an affordable solution to help them determine the extent of the sedimentation build-up within the harbour breakwater limits. A bathymetric survey was conducted and identified sedimentation build-up along the entire north breakwater section. A drone was also used to create a georeferenced orthomosaic map to help orientate anyone reviewing the survey.  This section of the breakwater runs parallel to the boat launch. It was later determined that because of the “Rubble” construction of the breakwater, the wave action on the north breakwater was causing sedimentation to migrate through the voids in the rocks. This sedimentation will need to be dredged to allow the full function of the harbour.



Sludge Mapper’s bathymetric survey was able to provide valuable information to Love Me Fish & Lobster who were then able to determine the root cause of the problem. Linda from Love Me Fish & Lobster stated, “We are happy that Sludge Mapper was able to provide us with valuable information about the harbour at an affordable price”. Linda went on to state “We’ll have them come in again periodically to monitor sedimentation build-up after the dredging happens”.
