Fishery Population Assessment Through Planktonic Sampling
The primary objective of this program is to develop an effective method for conducting plankton surveys in physically dynamic coastal environments. This goal is critical if we are to develop egg and larval production models in pelagic spawning, cold ocean species. As a management tool, egg production methods have been used successfully in other areas of the world, but to date are not used in Atlantic Canada. We seek to design a statistical optimization approach for guiding on-going surveys that will enable effective and accurate sampling in a coastal upwelling environment. One component of the program will be the implementation of data assimilation methods to a circulation model to enhance simulation modeling of the coastal circulation. In particular, we will apply these models to a series of ichthyoplankton surveys to verify the accuracy of the model. This dynamic oceanographic approach will be used in the assessment of inshore spawning stock abundance using Egg Production Methods. This research will enhance the design of plankton surveys and ensure statistically sound coverage while allowing for corrections resulting from losses and transport during the survey.
