What We Do

Fisheries Inventories

Fisheries Inventories

Fisheries inventories are necessary for managers to make informative decisions when dealing with development projects around waterways to ensure proper precautions are taken to mitigate impacts on fish and fish habitat.  Determining fish population dynamics, community structure, or presence/absence is also imperative to allow biologists to make informed decisions when regulating and managing a fishery.  At AAE Tech Services we are capable of conducting fisheries inventories in all type of water bodies large or small.  Our large inventory of fisheries equipment  including gill nets, trap nets, surber samplers, beamish nets, seine nets, larval drift nets, minnow traps, egg mats, and boat and backpack eletrofishing equipment allow us to sample for larval, juveniles, or adult fish.


REPRESENTATIVE STUDIES:

Fish and Habitat Assessment of Lake Manitoba North Basin Tributaries

A fisheries inventory was one component of a project conducted on four selected north basin Lake Manitoba tributaries to identify and document the current status of potential spawning habitat around Lake Manitoba. The ultimate goal of the project was to collect baseline data and to compile a list of possible remediation sites spawning habitat could be restored to improve fish populations within Lake Manitoba for the benefit of all.  Aquatic habitat inventories and riparian inventories were also conducted.  


Pine Falls fish Community Analysis

Spring, summer, and fall fisheries inventories were conducted upstream and downstream of the Pine Falls dam on the Winnipeg River to determine potential impacts resulting from a rerunnering project, with four of six turbines scheduled to be upgraded.  Habitat Suitability Index was calculated for numerous fish species upstream and downstream of the dam under a variety of flow conditions.


Non-lethal Sampling Protocal Nopiming Provincial Park Lakes

Non-lethal fish surveys were conducted on five lakes in the Nopiming Provincial Park to establish baseline data for helping to determine stocking rates and manage the fishery.  The sampling protocol included using boat electrofishing and the use of ESTN traps nets to sample for fish.  Otoliths were also removed and assessed for OTC markings from a subsample of walleye captured to determine the ratio between stocked (with mark) and naturally reproduced (without mark) walleye. 


Non-lethal Sampling Protocal Whiteshell Provincial Park Lakes

Non-lethal fish surveys were conducted on nine lakes in the Whiteshell Provincial Park to establish baseline data for helping to determine stocking rates and manage the fishery.  The sampling protocol included using boat electrofishing and the use of ESTN traps nets to sample for fish.  Otoliths were also removed and assessed for OTC markings from a subsample of walleye captured to determine the ratio between stocked (with mark) and naturally reproduced (without mark) walleye.
