Update from Corey Morris on Retrieving the Acoustic Hydrophones October 2009

Corey's most recent trip to the Gilbert Bay MPA involved getting acoustic hydrophones. He stated that putting the data together will take some time, but it does indicate that many cod are spending considerable time outside the MPA as they expected, including an area of Alexis Bay. Having said that, they did not retrieve the receivers from the outside hydrophones yet, so the picture is incomplete.

 
A couple weeks ago there was a scientific review of the Gilbert Bay cod monitoring program, conducted by DFO. Scientists provided a critique of the 5 monitoring indicators used to study trends in the Gilbert Bay cod population, and suggested ways to improve the current monitoring program. Corey stated it was a very positive science review, and provided some excellent advice. All in all, the 5 existing monition indicators that make up the program are useful. Some improvements were suggested, particularly in terms of data analysis and data collection. This information will be published in a DFO Science Advisory Report (general overview) and a DFO Research Document (detailed description) during the coming weeks. 
 
Corey stated that upcoming work during the winter will include analysis and write-up of the acoustic telemetry data. He is not sure if there will be funding available to make a trip to the area during this winter, but we (DFO and LMN) are interested in the winter location of Arctic Char that we tagged last summer. 
 
The Arctic Char work is a collaboration between DFO science and the LMN. They tagged Char within the MPA last summer and tracked their movements. 6 of 25 Char tagged were caught. They also put sonic receivers near the mouths of most brooks in the Gilbert Bay and Alexis Bay area. This should give them an idea of which brooks the Char went into. Corey stated it would be interesting to see if Char spend time in the MPA during the summer, and also where they spend the winter months.

Update on Sewage Outfall Monitoring

 

On September 17th, 2009 Laura Park, Marilyn Parr-Penney and Clayton Curl completed the Sewage Outfall Monitoring in William’s Harbour for another year. This regular check-up is done to ensure that the effluent is not so concentrated or toxic as to have a negative impact on the MPA. The monitoring includes visual examination and water sampling to determine levels of dissolved solids, dissolved oxygen, pH, salinity and temperature. The results were great with no issues to report.

Through the collaboration process between DFO and Memorial University of Newfoundland (MUN), considerable information about the Gilbert Bay cod and its ecosystem has been compiled.  This information has proven quite useful in the development of the Gilbert Bay MPA, as well as in the development of this website.  The strong commitment from both parties on continued research pertaining to the conservation, protection and ecological understanding of the MPA will lead to effective management of the area.
