Acoustic surveys for cod and capelin were first conducted in Placentia Bay in the winter of 1995. Since then, several surveys have taken place in conjunction with research on spawning areas and cod ecology. Acoustic surveys employing an EK500 split-beam system (38 kHz) were conducted in June, 1996, and June, 1998, from the CGSS Teleost, across a portion of 3Ps that included the outer part of Placentia Bay and a strip that ran to the shelf edge. Acoustic surveys were also undertaken in the inner portions of Placentia Bay and parts of the outer Bay using small vessels (Innovation and Mares) and a BioSonics DT4000 digital echosounding system. Surveys conducted in June 1996, May 1997, and June 1998 are reported here (closest in timing to the Teleost surveys). gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Lawson, G.
